The decrease in long-term interest rates this year has helped banks' bond portfolios recover a bit. Some of them may consider restructuring their securities portfolios in the short run, and longer-term changes are also possible as the fallout from last month's crisis continues.

The world's largest retailer sued Capital One over their four-year-old credit card partnership, saying the bank failed to meet customer service standards. The McLean, Virginia-based bank disputed the allegations, and analysts said that the firm could compensate by landing new credit card partnerships or cutting back on marketing expenses.

Some concerns linger over the sector after Silicon Valley Bank's collapse last month. The most pressing worry now, analysts say, is not whether banks will survive but how much money they'll make in the coming months.

The Spanish banking giant is doubling down on its U.S. operations, unlike other foreign-owned banks that have abandoned efforts to reach American consumers. It's doing so partly by better integrating its large auto lending business with its retail bank.

The banks invested in bonds at a time when rates were low, and their value has since dropped substantially. While there appears to be very little risk that the banks will ever have to realize the losses, an American Banker data analysis raises questions about whether regulators should toughen their monitoring of interest rate risk.

There were many red flags before the California bank failed last week. Now the questions are: How did federal and state regulators assess the risks, and what actions did they take in response?

Many banks whose shares got hammered a day earlier rebounded strongly, with double-digit gains at Western Alliance Bancorp, First Republic Bank and PacWest Bancorp in midafternoon trading.

The KBW Nasdaq Bank Index dropped 9.6% on Monday as the fallout from two bank failures prompted investors to trim their exposures. Some regional institutions saw declines of 30% or more, while the nation's largest banks had much more modest declines.

The San Francisco-based bank, whose stock came under pressure after the failure of Silicon Valley Bank, said the increased borrowing capacity strengthens and diversifies its funding. The bank's "capital and liquidity positions are very strong," executives said.

The bank's tech-sector focus contributed to its rapid demise. But the reasons for its failure come down to the nuts and bolts of banking, and other banks may have similar vulnerabilities.
