Why investors are worried about banks
The problem for SVB was that it held many bonds that were bought back when interest rates were low. Over the past year, the Federal Reserve has raised interest rates eight times to combat the highest inflation in generations. As rates went up, newer versions of bonds became more valuable to investors than those SVB was holding.
Even before SVB capsized, investors were racing to figure out which other banks might be susceptible to similar spirals.
With the tech industry cooling, some of SVB’s customers began withdrawing their money. To come up with the cash to repay depositors, SVB sold $US21 billion of bonds. The bank racked up nearly $US2 billion in losses.
Those losses set off alarms with investors and some of the bank’s customers. If the rest of SVB’s balance sheet was riddled with similar money-losing assets, would the bank be able to come up with enough money to repay its depositors?
Rather than wait around to find out, customers rushed to withdraw their funds — tens of billions of dollars. A classic bank run was underway.
Even before SVB capsized, investors were racing to figure out which other banks might be susceptible to similar spirals. One bright red flag: large losses in a bank’s bond portfolios. These are known as unrealised losses — they turn into real losses only if the banks have to sell the assets.
Since the Fed began raising interest rates, banks have faced growing unrealised losses.
These unrealised losses are especially notable as a percentage of a bank’s deposits — a crucial metric, since more losses mean a greater chance of a bank’s struggling to repay its customers.
At the end of last year, US banks faced more than $US600 billion of unrealised losses because of rising rates, federal regulators estimated.
Those losses had the potential to chew through more than one-third of banks’ so-called capital buffers, which are meant to protect depositors from losses, according to Fitch Ratings. The thinner a bank’s capital buffers, the greater its customers’ risk of losing money and the more likely investors and customers are to flee.
But the $US600 billion figure, which accounted for a limited set of a bank’s assets, might understate the severity of the industry’s potential losses. This past week alone, two separate groups of academics released papers estimating that banks faced at least $US1.7 trillion in potential losses.
The most skittish bank customers tend to be those whose deposits are uninsured.
This was a huge problem at SVB, where more than 90 per cent of deposits exceeded the amounts covered under federal insurance. The Federal Deposit Insurance Corporation insures deposits for individual accounts up to $US250,000, and many other banks also have elevated levels.
To make matters worse, many banks — especially those with $US50 billion to $US250 billion in assets — kept less than 4 per cent of their assets in cash, according to Fitch.
Banks with less cash on hand may be more likely to bear losses if there is a rush of withdrawals.
Midsize banks such as SVB do not have the same regulatory oversight as the nation’s biggest banks, which, among other provisions, are subject to tougher requirements to have a certain amount of reserves in moments of crisis. But no bank is completely immune to a run.
Two separate groups of academics released papers estimating that banks faced at least $US1.7 trillion in potential losses.
“I don’t think anybody’s built to withstand 25 per cent of their deposits leaving in a day, which is what happened” in the case of SVB, said Nathan Stovall, a banking analyst at S&P Global Market Intelligence.
The Federal Reserve and other regulators are rushing to reassure everyone. Recently, the Fed announced a program that offers loans of up to one year to banks using the banks’ government bonds and certain other assets as collateral.
Crucially, the Fed said it would value the bonds at their original value — not at the lower levels that banks stood to receive if they tried to quickly sell them in the markets. The Fed’s goal was to send a reassuring signal that banks would not have to transform unrealised, potential losses into crippling actual ones.
At least so far, that program hasn’t been much of a game changer. Banks borrowed only about $US12 billion — a small fraction of the deposits that were pulled out of SVB alone before its implosion.
But banks gobbled up a whopping $US153 billion in loans through the Fed’s traditional lending program. That was up from less than $US5 billion a week earlier and was the largest amount borrowed in a week since the 2008 financial crisis.
The fright that began with SVB has continued to spread to other banks.
On Wednesday, Swiss authorities vowed to protect the giant bank Credit Suisse as concerns about its stability swirled. The next day, the US authorities helped organise an industry bailout of First Republic — one of the large banks that had attracted particular attention from nervous investors.
The troubles lurking in the balance sheets of small banks could have a large effect on the economy. The banks could change their lending standards in order to shore up their finances, making it harder for a person to take out a mortgage or a business to get a loan to expand.
Analysts at Goldman believe that this will have the same impact as a Fed interest rate increase of up to half a point. Economists have been debating whether the Fed should stop raising rates because of the financial turmoil, and futures markets suggest that many traders believe it could begin cutting rates before the end of the year.
Investors have continued to pummel the shares of regional bank stocks. First Republic’s stock is down more than 80 per cent for the year, and other regional banks such as Pacific Western and Western Alliance have lost more than half their values.
Investors, in other words, are far from convinced that the crisis is over.
