Economists are watching for the aftereffects of recent bank collapses across many industries. How bad could it get?Sarah Puil needs to buy $500,000 to $1 million of premium wine and other inventory by the end of the year to make into the specialty blends that her company sells and ships to customers around the country. But after the collapse of Silicon Valley Bank started a chain reaction that is causing many types of funding to dry up, she is not sure where she is going to get the cash.Boxt, her three-year-old purveyor of upscale boxed wine, is at a vulnerable stage in which access to credit is crucial to its growth and ability to keep producing its red, white and rosé offerings.As banks and other investors retrench because of the turmoil, Ms. Puil and fellow entrepreneurs are finding that borrowing and raising money are more difficult and expensive.“It’s all we’re talking about,” she said. The demise of the bank, a major lender to the tech and wine industries, “accelerated the tightening of venture capital — that’s the big thing,” she said.Boxt’s worries offer a hint of the economic fallout facing borrowers across the country as credit becomes harder to get. It is too soon to say how much the banking tumult could slow the economy, but early evidence points to increased caution among banks and investors.Taking out big mortgages is getting harder, industry experts report. The commercial real estate industry is bracing for trouble as the midsize banks that service it become more cautious and less willing to lend. Used car loans are more expensive. And a recent survey by the Federal Reserve Bank of Dallas showed a sizable share of banks in the region reporting stricter credit standards.The question now is whether banks and other lenders will pull back so much that the U.S. economy crashes into a severe recession. Until comprehensive data is released — a Federal Reserve survey of loan officers nationwide is due in early May — economists are parsing stories from small businesses, mortgage originators and construction firms to get a sense of the scale of the disruption. Interviews with more than a dozen experts across a variety of industries suggested that the effects are beginning to take hold and could intensify.“People are for the first time in some time using the ‘c’ words: credit crunch,” said Anirban Basu, chief economist at Associated Builders and Contractors, a trade association. “What I’m hearing — and what I’m beginning to hear from contractors — is that credit is beginning to tighten.”Silicon Valley Bank’s collapse on March 10 sent shock waves across the banking world: Signature Bank failed on March 12, First Republic required a $30 billion cash injection from other banks on March 16 and, in Europe, Credit Suisse was sold to its biggest rival in a hastily brokered deal on March 19.The situation seems to have stabilized, but depositors have continued to drain cash from bank accounts and put it into money market funds and other investments. Early Fed data on the banking system, released each Friday, has suggested that commercial and industrial lending and real estate lending both declined meaningfully through late March.When banks lose deposits, they lose a source of cheap funding. That can make them less willing and able to extend loans. The threat of future turmoil can also make banks more cautious.When lending becomes more difficult and expensive, fewer businesses expand, more projects fail and hiring slows — laying the groundwork for a broader economic slowdown.Bags of a rosé wine blend. Boxt’s worries about its access to credit offer a hint of the economic fallout facing borrowers.Tamir Kalifa for The New York TimesThat sequence is why officials at the Fed believe the recent upheaval will cause at least some damage to the economy, though nobody is sure how much.Any slowdown will intensify conditions that were already getting tougher for borrowers. The Fed has been raising interest rates for the past year, making money more expensive to borrow, and labor market data released on Friday offered the latest evidence that demand is beginning to slow enough to cool the economy, weighing on hiring and wage gains.Still, many Fed officials had come into March anticipating that they might lift rates a few more times in 2023 until inflation comes under control. Now, the banking fallout may restrain the economy enough to make further moves less urgent, or even unnecessary.“It is too soon to determine the extent of these effects and therefore too soon to tell how monetary policy should respond,” Jerome H. Powell, the Fed chair, said at a news conference last month.Aftershocks are already surfacing. Commercial real estate borrowers rely heavily on midsize regional banks, which have been particularly hard-hit by the turbulence. Those banks were already become pickier as interest rate increases bit, said Stephen Buschbom, research director at Trepp, a commercial real estate research firm. Anecdotally, Silicon Valley Bank’s blowup is making it worse.“It’s not easy to get a loan commitment is the bottom line,” Mr. Buschbom said.Tougher credit could bedevil a sector that was already suffering: Office real estate has struggled in the pandemic as many city workers have eschewed their desks. Mr. Buschbom says he thinks many borrowers will struggle to renew their loans, forcing some into what’s known as special servicing, where they pay interest but not principal. And as distress trickles through the industry, it could worsen the pain for midsize banks.The problems could mean less business for contractors like Brett McMahon, chief executive of the concrete construction firm Miller & Long in Bethesda, Md.“I don’t think it’s 2008, 2009 — that was such an extraordinarily severe event,” Mr. McMahon said. But he thinks the bank blowups are going to intensify the tightening of credit. He’s being cautious, trying to eke more time out of aging machines. He expects to pause hiring by the end of the year.“Most contractors will tell you that 2023 looks decent,” he said. “But 2024: Who the hell knows?”When it comes to the residential real estate market, jumbo loans — those above about $700,000 or $1 million, depending on the market — were already becoming more expensive. Now, Michael Fratantoni, the chief economist at the Mortgage Bankers Association, has been hearing from bankers that deposit outflows in the wake of Silicon Valley Bank’s demise mean banks have less room to create and hold such loans.Ali Mafi, a Redfin real estate agent, has noticed big banks tightening their standards a bit for borrowers in San Francisco. It’s nothing like the 2008 financial crisis, but over the past few weeks, they have begun asking that would-be borrowers keep a couple of more months of mortgage payments in their bank accounts.Still, he hopes the fallout will not be extreme: Some mortgage rates have eased as investors anticipate fewer Fed rate moves, which is combining with higher stock prices and a drop in local house prices to counteract some of the banking issues.Auto loan interest rates have risen sharply, based on credit application data from March analyzed by Cox Automotive. Borrowing costs for used cars rose more than three-quarters of a percentage point in a month, said Jonathan Smoke, Cox’s chief economist. New car loans also became more expensive, though not as significantly.“The auto market is going to have some challenges,” Mr. Smoke said. But there’s a silver lining: “We haven’t seen appreciable declines in approval rates.”Ms. Puil, right, joined other senior company executives in preparing the packaging for wine shipments at Boxt’s fulfillment center in Austin, Texas.Tamir Kalifa for The New York TimesThere are also reasons for hope in the wine industry. Winemakers have been on “tenterhooks” since Silicon Valley Bank’s collapse, said Douglas MacKenzie, a partner at the consulting firm Kearney, partly because many big banks “don’t know the difference between a $100 case of sauvignon and a $2,000 case” when it comes to valuing collateral that can be “quite liquid, no pun intended.”But he noted that the Bank of Marin, a regional lender, had been running ads in trade magazines saying it was open to new customers. There is also interest in the private equity industry, with which he works.And Ms. Puil at Boxt is determined to get through the crunch.“I’m going to find that money,” she said. Failing because of a lack of credit “can’t be how this story ends.” More
