U.S.|Coronavirus Live Updates: Officials Struggle With When to Lift Restrictions, Weighing the Economy Against Public Health

The question of when and how to restart the economy dominated discussions on Sunday, with one expert calling for a “rolling re-entry” to normalcy. Many Americans attended Easter services from their living rooms.

Right Now

Getting the economy back to normal after the pandemic may take 18 months, and leaders should plan accordingly, according to a Federal Reserve president who helped lead the Treasury’s response to the 2008 financial crisis.

Questions loom about reopening the economy: ‘You can’t just pick a date and flip a switch.’

With most stores closed and millions of American filing for unemployment benefits, officials explored the question on Sunday of when and how to ease protective measures and start reopening the economy. The discussion came even as much of the country was dealt yet another reminder of just how much life has been upended by pandemic.

President Trump has been open about his eagerness to see stay-at-home orders lifted as soon as May. But officials who see the death tolls still rising in their cities and states urged caution, fearing that relaxing restrictions prematurely could allow the virus to surge once again.

“We could be pouring gas on the fire, even inadvertently,” Gov. Philip D. Murphy of New Jersey, a Democrat, said in an interview on CNN, explaining that while returning to a semblance of life before the outbreak was the goal, “it’s not Job No. 1., because right now, the house is on fire and Job No. 1 is to put the fire out.”

As the debate played out on the Sunday talk shows, millions of Christians in the United States celebrated Easter separated from their extended families and fellow believers, watching religious services broadcast on television or streamed online.

Presiding over Mass in a largely empty St. Peter’s Basilica in the Vatican, Pope Francis described “the contagion of hope” as he acknowledged that for many, “this is an Easter of solitude, lived amid the sorrow and hardship that the pandemic is causing, from physical suffering to economic difficulties.”

Indeed, the impact of the pandemic has intensified around the world. In Britain, where Prime Minister Boris Johnson has recovered from Covid-19 enough to be released from the hospital on Sunday, the total number of reported coronavirus deaths has surpassed 10,000. And officials in Russia reported more than 2,100 new cases on Sunday, the largest daily increase there since the start of the outbreak.

The United States also recently marked a grim milestone, surpassing Italy in the total number of confirmed coronavirus deaths, reaching its deadliest day on Friday with 2,057 deaths. As of Saturday night, the total stood at more than 20,500. On Sunday, New York, the epicenter of the virus, reported that another 758 more people had died, bringing total in the state to 9,385.

Tens of thousands more could die. Millions more could lose their jobs. And the president’s handling of the crisis appears to be hurting his political support in the run-up to the November election.

The pandemic has put more than 16 million people out of work in the United States in the space of a few weeks, forcing Mr. Trump to grapple simultaneously with the most devastating public health and economic crises in a lifetime. He finds himself pulled in opposite directions, with bankers, corporate executives and industrialists pleading with him to reopen the country as soon as possible, while medical experts beg for more time to curb the coronavirus.

Mr. Trump has acknowledged the gravity of the question of when to reopen the country. “I’m going to have to make a decision, and I only hope to God that it’s the right decision,” he said.

But the decision is not entirely his to make. The closures and movement restrictions now in place have largely been imposed through a patchwork of orders issued by states, counties and cities. Many governors have expressed wariness about lifting them prematurely.

“We’ve got to balance those needs,” Gov. Larry Hogan of Maryland, a Republican, said on the ABC program “This Week” about weighing public health concerns against economic considerations. “But, really, right now, the first thing is saving lives and keeping people safe. We do also have to think about how do we eventually ramp up and get some folks back to work. But you can’t just pick a date and flip a switch. I don’t think it’s going to be that simple.”

Arkansas is one of the few states not to impose a statewide stay-at-home order. Gov. Asa Hutchinson said on CNN Sunday said while such an order might have been essential in limiting the virus’s spread in other places, it was not as important in his state, most of which is far less densely populated than New York or New Jersey. “It just reflects the flexibility a state needs,” said Mr. Hutchinson, a Republican.

He noted that the hospitalization rate in Arkansas had been low so far. The state, with a population of 3 million, has reported 1,280 cases and 27 deaths through Sunday.

Arkansas has called for strict social distancing, but has allowed businesses to stay open and people to go to work. “That’s the important balance that we have in our state,” he added. “If we need to do more, we will do more.”

Dr. Anthony S. Fauci, the director of the National Institute of Allergy and Infectious Diseases, said on Sunday that reopening the country would not be an “all or none” proposition. Dr. Fauci said in an interview with CNN that restrictions must be lifted in a gradual manner to prevent a resurgence of cases. Computer models project that lifting all social-distancing measures at once nationally may set the stage for a rebound sometime in July.

“If all of a sudden we decide, ‘OK, it’s May, whatever, and we just turn the switch on, that could be a real problem,” Dr. Fauci said.

He said governors will need to manage a “rolling re-entry,” guided by testing results and local risk levels. “I think it could probably start, at least in some ways, maybe next month,” he said on the network’s “State of the Union” program, though he added, “Don’t hold me to it.”

Getting the economy back to normal may take 18 months, a Fed official says.

Policymakers should be thinking about the coronavirus as an 18-month problem, said Neel Kashkari, a Federal Reserve president who helped lead the response to the 2008 financial crisis as a Treasury Department official.

“This could be a long, hard road that we have ahead of us,” he said, adding that waves of flare-ups could make this last for 18 months, and officials should prepare for that by considering how to reopen the economy piecemeal.

“If it ends up being shorter than that, that’s great,” he said. “We should prepare for the worst-case scenario.”

Mr. Kashkari, who is president of the Federal Reserve Bank of Minneapolis, said that if the economic pain lasts, it could spill into the banking sector, even necessitating government intervention.

“People don’t pay their mortgage, a coffee shop doesn’t pay their landlord, the landlord then can’t pay the bank’s mortgage,” he said.

“Right now the banks are well capitalized relative to where they were in 2006,” he said, but if “this goes on long enough, it could produce strains on the banking sector, and then the Fed, and Congress and Treasury, would have to step in to make sure that the banks are sound.”

Celebrating Easter, in empty churches. Some pastors resist.

Millions of Americans tuned in to online church services Sunday morning to celebrate one of the holiest days of the Christian calendar. For most Christian denominations, today is Easter. (Most Orthodox churches will mark Easter on April 19.)

The vast majority of churches celebrated virtually, while a handful of pastors in states like Louisiana and Mississippi defied stay-at-home guidance and hosted in-person worship services, risking the health of their followers and their own arrests.

Others attempted something in between. In Franklin, Ky., Victory Hill Church hosted a service at a drive-in movie theater, where people worshiped in their cars.

In St. Patrick’s Cathedral in New York, Cardinal Timothy M. Dolan prayed over the communion cup and wine, his voice echoing across empty pews to the locked front door, as parishioners watched online.

President Trump said on Twitter that he would watch the online service of First Baptist Dallas, led by Robert Jeffress, a prominent Trump supporter who has said that non-Christian religions are sending their followers to hell. Vice President Pence said he would also attend church virtually.

On Sunday morning Mr. Trump posted a short video urging people to follow social distance guidelines on the holiday.

In Dallas, Mr. Jeffress thanked Mr. Trump from the pulpit of First Baptist for defending religious liberty. In his service on Sunday, Mr. Jeffress portrayed Mr. Trump as a supporter of religion, although the president does not regularly attend church or exhibit deep knowledge about the Bible.

Mr. Jeffress has lashed out at other faiths, calling the Catholic Church an instrument of Satan, describing the Church of Jesus Christ of Latter-Day Saints as “a cult,” claiming that Islam “promotes pedophilia”and saying that Jews, Muslims and others would go “to Hell.”

On the National Mall in Washington, a few people gathered on the steps of the Lincoln Memorial to sing hymns and watch the sun rise.

Restrictions on mass gatherings have frustrated a small number of religious conservatives, who see the rules as attempts to limit Christian practice. In Kentucky, a federal judge on Saturday blocked the mayor of Louisville, Greg Fischer, from restricting drive-in church services, noting that drive-in liquor stores were still open.

The Supreme Court of Kansas ruled late Saturday night to uphold Gov. Laura Kelly’s order limiting the size of church services on Easter Sunday to 10 people. Republican legislators had argued it restricted their constitutional freedoms.

The Department of Justice may take action next week against local leaders who have restricted in-person gatherings. Attorney General William Barr is “monitoring” government regulation of religious services, a Department of Justice spokeswoman said in a tweet on Saturday night.

“While social distancing policies are appropriate during this emergency, they must be applied evenhandedly & not single out religious orgs,” the spokeswoman, Kerri Kupec, wrote. “Expect action from DOJ next week.”

The outbreak in New York may be leveling off, but at a high level.

Gov. Andrew M. Cuomo said on Sunday that 758 more people had died in New York State, but that other data showed that virus’s spread was slowing in the state.

The governor’s morning update tracked closely with news from the state over the last week: daily death tolls approaching 800 and the rate of hospitalizations continuing to fall. The governor compared his experience of the outbreak to the film “Groundhog Day,” saying that each day felt like a repeat of the day before.

Mr. Cuomo again criticized the federal response to the coronavirus, saying that money had been misdirected, with states that were less hard hit getting a disproportionate share.

He said that he would sign an executive order requiring employers at essential businesses to provide employees with cloth or surgical face masks to wear when interacting with the public.

In all, the state has now had 9,385 deaths related to the coronavirus, the governor said.

Throughout January, as President Trump repeatedly played down the seriousness of the virus and focused on other issues, an array of figures inside his government — including top White House advisers and experts deep in the cabinet departments and intelligence agencies — identified the threat, sounded alarms and made clear the need for aggressive action.

Dozens of interviews and a review of emails and other records by The New York Times revealed many previously unreported details of the roots and extent of his halting response:

  • The National Security Council office responsible for tracking pandemics received intelligence reports in early January predicting the spread of the virus, and within weeks raised options like keeping Americans home from work and shutting down large cities.

  • Despite Mr. Trump’s denial, he was told at the time about a Jan. 29 memo produced by his trade adviser, Peter Navarro, laying out in striking detail the potential risks of a coronavirus pandemic.

  • The health and human services secretary directly warned Mr. Trump of the possibility of a pandemic during a call on Jan. 30, the second warning he delivered to the president about the virus. The president said he was being alarmist.

  • The health secretary publicly announced in February that the government was establishing a “surveillance” system in five American cities to measure the spread of the virus. It was delayed for weeks, leaving administration officials with almost no insight into how rapidly the virus was spreading.

Asked on Sunday morning whether lives would have been saved if Mr. Trump had followed recommendations on social distancing in late February, Dr. Fauci said on CNN, “It is what it is; we are where we are right now.” He added: “Obviously you could logically say that if you had a process that was ongoing and you started mitigation earlier, you could have saved lives, nobody’s going to deny that.”

Dr. Tom Inglesby, director of the Center for Health Security of the Johns Hopkins Bloomberg School of Public Health said on “Fox News Sunday” that “if we had acted on some of those warnings earlier, we would be in a much better position in terms of diagnostics and possibly masks and personal protective equipment and getting our hospitals ready.”

F.D.A. chief urges caution on antibody tests.

Coronavirus antibody tests have not always been accurate in other countries, and the United States should be careful not to approve their use too quickly, Dr. Stephen Hahn, the commissioner of the Food and Drug Administration, said on Sunday.

Antibody tests are not designed to detect whether someone is infected now; they tell doctors whether the person has been exposed to the virus at some point, and may have acquired some degree of immunity. So far, the F.D.A. has approved only one such test.

“There are a number on the market that we haven’t validated,” Dr. Hahn said on the ABC program “This Week.” “We do expect that relatively soon.”

Referring to reports from other countries of inaccurate antibody tests, he added: “I think it’s really important for the American people to know that we need tests that are accurate, reliable and reproducible.”

In an appearance on the NBC program “Meet the Press,” Dr. Hahn said, “What we don’t want are wildly inaccurate tests.”

Boris Johnson, out of the hospital, hails Britain’s National Health Service.

Prime Minister Boris Johnson of Britain, who contracted the coronavirus and spent time in intensive care, showered praise on his country’s often-criticized National Health Service after being released from the hospital on Sunday.

It was a major step forward in his recovery and a welcome relief for a nation whose death toll from the pandemic has surpassed 10,000 and whose political leadership has been hard hit by the contagion.

In a video posted on Twitter, he credited the National Health Service with saving his life, calling it “the beating heart of this country.”

“It’s hard to find words to express my debt,” he said, looking a bit wan but speaking with his usual vigor.

He thanked Britons for adhering to social distancing measures and said that they were helping to slow the spread of the virus. And he singled out two nurses — Jenny, from New Zealand, and Luis, from Portugal — who “stood by my bedside for 48 hours when things could have gone either way.”

The toll of keeping Florida open during the spring break season has started to become apparent.

Weeks before Florida ordered people to stay at home, the coronavirus was well into its insidious spread in the state, infecting residents and visitors who days earlier had danced at beach parties and reveled in theme parks. Only now, as people have gotten sick and recovered from — or succumbed to — Covid-19, has the costly toll of keeping Florida open during the spring break season started to become apparent.

Gov. Ron DeSantis, a Republican, has blamed travelers from New York, Europe and other places for seeding the virus in the state. But the reverse was also true: People got sick in Florida and took the infection home.

The exact number of people who returned from leisure trips to Florida with the coronavirus may never be known. Cases as far away as California and Massachusetts have been linked to the Winter Party Festival, a beachside dance party and fund-raiser for the L.G.B.T.Q. community held March 4-10.

As of last week, 38 people had reported that they were symptomatic or had tested positive for the coronavirus in the weeks after the event, according to the organizer, the National L.G.B.T.Q. Task Force.

Another California man died after going to Orlando for a conference and then to a packed Disney World. Two people went to Disney and later got relatives sick in Florida and Georgia.

Slow action by Florida’s governor left local leaders scrambling to make their own closure decisions during one of the most profitable times of the year for a state with an $86 billion tourism economy. The result was that rules were often in conflict from one city to another.

The governor, who did not order people to stay home until April 1, has said the state supported local governments that ordered event cancellations and beach closures, but that it was not his role to step in first.

Scientists look at why some people are more infectious than others.

As the coronavirus tears through the country, scientists are studying the role of superspreaders, a loosely defined term for people who may infect a disproportionate number of others, whether as a consequence of genetics, social habits or simply by being in the wrong place at the wrong time.

The virus carriers at the heart of what are being called superspreading events can drive epidemics, researchers say, making it crucial to figure out ways to identify spreading events or to prevent situations, like crowded rooms, where superspreading can occur.

At the end of February, for example, when 175 Biogen executives gathered for a conference at the Boston Marriott Long Wharf Hotel, at least one was infected with the coronavirus. Two weeks later, 75 percent of the 108 Massachusetts residents infected with the virus were associated with or employed by Biogen.

But just as important are those at the other end of the spectrum: people who are infected but unlikely to spread the infection.

Distinguishing between those who are more infectious and those less infectious could make an enormous difference in how an outbreak is contained, said Jonathan Zelner, a statistician at the University of Michigan.

Envoy to W.H.O. tries to calm the waters with Washington.

Responding to Mr. Trump’s threat that the United States might withhold funding from the World Health Organization, one of the group’s top officials said Sunday that it would be “so unfortunate” if anything happened to lessen the cooperation between the organization and Washington.

On Tuesday, Mr. Trump accused the W.H.O. of not having been aggressive enough in confronting the coronavirus, suggesting he would put “a very powerful hold” on the funding the United States provides the organization.

The budget for the W.H.O. is about $6 billion, and in 2019, the last year for which figures were available, the United States contributed about $553 million.

Dr. David Navarro, the special envoy to the W.H.O., said on NBC’s “Meet the Press” that he hoped “that all nations will not find any reason to make threats or other such things that will undermine our capacity to bring together all the best knowledge that we can find.”

He added, “We’ve worked with United States scientists for years. I personally have huge respect for what you bring and what you offer.”

Pregnant in the Coronavirus Epicenter

The Brooklyn Hospital Center’s maternity floor is a place of anxiety for staff and patients. But amid the fear, mothers with Covid-19 are experiencing moments of joy and gratitude.

This is Precious Anderson. She was pregnant. About two months before her due date, she had severe Covid-19. Actually so severe that her baby had to be delivered by c-section to try to save both of their lives. In fact, she couldn’t actually visit her baby “Here you go, Precious.” And then it was amazing because we got to watch her video chat with a nurse who was with her baby and Precious Anderson got to see her baby, David. “Wonderful, right?” “He’s so handsome, Precious. He’s very handsome.” We actually went to visit him and he was moving around. He was stretching, pointing his toes like a little dancer. He was so, so cute. Actually he tested negative for Covid. At this hospital, seven of the pregnant who tested positive for Covid have given birth and their babies have generally done very well. None of them have been confirmed to have Covid. I’m Sheri Fink. I’m a correspondent at the New York Times. For the past several weeks, Victor Blue, a photographer, and I have been able to spend time at the Brooklyn Hospital Center. And for the story published this week, we spent time with pregnant mothers on maternity and in the intensive care unit. Dr. Erroll Byer is the Chair of Obstetrics and Gynecology. And he said that this moment, which should be such a joyful moment in a family’s life, bringing new life into the world, that, in fact, now it’s anxiety provoking. “How you doing?” What struck me was people doing the typical things you would do on a maternity ward, but doing them with masks, with face shields, with gloves, with gowns. Many, many of the staff members on the maternity ward and in the neonatal I.C.U. are out sick. So there is a level of fear. Basharrie McKenzie was also on the intensive care unit. And she’s pregnant, and she got very sick with Covid. She was so afraid. And of course, it’s really hard because you’re alone. You can’t have any visitors. When I met her this Monday, she was so much improved. “My three-year-old daughter keeps me going.” And she was able to continue her pregnancy. “Your respirations are pretty okay.” “Okay?” “Very good.” So, there are a lot of very sad stories with Covid-19 — people in the intensive care unit — many, many of them not making it. So it was amazing to see this young woman, who had been so, so sick, was able to pack up her bags and actually go home. And she’s one of the success stories. “You made it.” “You’re telling a great story, honey.” “We’re proud.” “You got to have heart, and you had it.” “So we’re very proud of you.” “Thank you for allowing us to take care of you.” “Thank you.” I spoke with the intensive care unit doctors and they said when people like Ms. McKenzie get to leave the hospital, get to come off a ventilator, out of an intensive care unit, and recover enough to go home that it’s giving them the energy to keep going.

The obstetrics unit at Brooklyn Hospital Center, which delivers about 2,600 babies a year, is typically a place of celebration and fulfilled hopes. Amid the coronavirus pandemic, it has been transformed.

Nearly 200 babies have arrived since the beginning of March, according to Dr. Erroll Byer Jr., chairman of the department of obstetrics and gynecology. Twenty-nine pregnant or delivering women have had suspected or confirmed cases of Covid-19, the disease caused by the virus. They have been kept separate from other patients. Mothers-to-be are confined to their rooms, and visitors are kept to a minimum. Multiple doctors and nurses in the department have fallen ill.

Even healthy pregnant women are anxious. “They don’t feel the happiness and joy that many people experience” at this time of life, Dr. Byer said. Worse, some pregnant patients who become sick are so scared of coming into the hospital — citing fear of the virus or of being alone — that they have delayed doing so. A few of them have become dangerously ill.

As at other New York hospitals, the surge of new patients with Covid-19 flattened this past week. But nearly 90 patients at the Brooklyn hospital who were confirmed or suspected to have the virus have died since March 1, 30 of them from Monday to Friday last week. Five staff members have also died. The crisis is not over, Dr. Byer and other physicians warned.

Pregnant women are thought to be at a similar risk for severe illness from Covid-19 as other people. But Dr. Byer said that more research was needed, particularly in communities, like Brooklyn, where obesity, diabetes and hypertension are common among expectant mothers.

But he is grateful: So far, not one mother or baby has been lost.

Lines for basic needs stretch across America.

Standing in line used to be an American pastime, whether it was camping outside movie theaters before a “Star Wars” premiere or shivering outside big-box stores to be the first inside on Black Friday.

The coronavirus has changed all that.

Now, millions of people across the country are risking their health to wait in tense, sometimes desperate, new lines for basic needs. Carefully spaced, people stretch around blocks and clog two-lane highways.

The scenes are especially jarring at a moment when freeways are empty and city centers are deserted. Public health officials are urging people to slow the transmission of the coronavirus by avoiding each other.

“It’s worrisome,” said Carl Bergstrom, a biologist at the University of Washington who studies pandemics. “It’s setting up unnecessary opportunities for transmission.”

In Milwaukee, Catherine Graham, who has a bad heart and asthma, left her apartment on Tuesday for the first time since early March to vote in the Wisconsin primary election.

“It was people, people, people,” Ms. Graham, 78, said. “I was afraid.”

She said she nearly turned back when she saw the line, but waited for two hours to cast a ballot. Every day since, she has been watching for symptoms of the coronavirus.

Guam is the center of the U.S. Navy’s coronavirus outbreak.

Strapped by the same problems facing health care workers around the world, including a limited supply of personal protective equipment, hospital beds and ventilators, Guam’s government is contending with how to help the crew of infected sailors on the aircraft carrier U.S.S. Theodore Roosevelt, which arrived on March 27. The outbreak on the ship ended up creating a moral crisis for the military.

As an American territory roughly 7,200 miles from the continental United States, Guam is home to Joint Region Marianas, a military command made up of Andersen Air Force Base on the northern part of the island that supports stealth-bomber rotations, and Naval Base Guam to the south, where four attack submarines are stationed to counter Chinese military expansion in the South China Sea.

Local residents, sailors from the Roosevelt and their loved ones described a complicated situation on the island. Guam is providing logistical support to the Navy while also trying to protect the local population from the coronavirus, which could quickly overwhelm Guam’s fragile health care system.

Here’s what’s happening around the globe.

Pope Francis livestreamed Easter Mass, and spoke of a “contagion of hope,” in the midst of a “pandemic severely testing our whole human family.” The outbreak is fanning anti-Muslim attacks in India. As the demand for tulips dropped precipitously, Dutch growers found themselves having to destroy their flowers.

    • When will this end?

      This is a difficult question, because a lot depends on how well the virus is contained. A better question might be: “How will we know when to reopen the country?” In an American Enterprise Institute report, Scott Gottlieb, Caitlin Rivers, Mark B. McClellan, Lauren Silvis and Crystal Watson staked out four goal posts for recovery: Hospitals in the state must be able to safely treat all patients requiring hospitalization, without resorting to crisis standards of care; the state needs to be able to at least test everyone who has symptoms; the state is able to conduct monitoring of confirmed cases and contacts; and there must be a sustained reduction in cases for at least 14 days.

    • What should I do if I feel sick?

      If you’ve been exposed to the coronavirus or think you have, and have a fever or symptoms like a cough or difficulty breathing, call a doctor. They should give you advice on whether you should be tested, how to get tested, and how to seek medical treatment without potentially infecting or exposing others.

    • Should I wear a mask?

      The C.D.C. has recommended that all Americans wear cloth masks if they go out in public. This is a shift in federal guidance reflecting new concerns that the coronavirus is being spread by infected people who have no symptoms. Until now, the C.D.C., like the W.H.O., has advised that ordinary people don’t need to wear masks unless they are sick and coughing. Part of the reason was to preserve medical-grade masks for health care workers who desperately need them at a time when they are in continuously short supply. Masks don’t replace hand washing and social distancing.

    • How does coronavirus spread?

      It seems to spread very easily from person to person, especially in homes, hospitals and other confined spaces. The pathogen can be carried on tiny respiratory droplets that fall as they are coughed or sneezed out. It may also be transmitted when we touch a contaminated surface and then touch our face.

    • Is there a vaccine yet?

      No. Clinical trials are underway in the United States, China and Europe. But American officials and pharmaceutical executives have said that a vaccine remains at least 12 to 18 months away.

    • What makes this outbreak so different?

      Unlike the flu, there is no known treatment or vaccine, and little is known about this particular virus so far. It seems to be more lethal than the flu, but the numbers are still uncertain. And it hits the elderly and those with underlying conditions — not just those with respiratory diseases — particularly hard.

    • What if somebody in my family gets sick?

      If the family member doesn’t need hospitalization and can be cared for at home, you should help him or her with basic needs and monitor the symptoms, while also keeping as much distance as possible, according to guidelines issued by the C.D.C. If there’s space, the sick family member should stay in a separate room and use a separate bathroom. If masks are available, both the sick person and the caregiver should wear them when the caregiver enters the room. Make sure not to share any dishes or other household items and to regularly clean surfaces like counters, doorknobs, toilets and tables. Don’t forget to wash your hands frequently.

    • Should I stock up on groceries?

      Plan two weeks of meals if possible. But people should not hoard food or supplies. Despite the empty shelves, the supply chain remains strong. And remember to wipe the handle of the grocery cart with a disinfecting wipe and wash your hands as soon as you get home.

    • Should I pull my money from the markets?

      That’s not a good idea. Even if you’re retired, having a balanced portfolio of stocks and bonds so that your money keeps up with inflation, or even grows, makes sense. But retirees may want to think about having enough cash set aside for a year’s worth of living expenses and big payments needed over the next five years.
