FirstFed was No. 5 on the list, at 6.7%, up from 0.5% a year earlier. Washington Mutual was No. 12, at 3.9%, up from 1.6% a year earlier.
All three banks have sought to reassure customers and investors that they are not at risk of failing like IndyMac. In a statement Monday, Downey said its bank had raised $62 million in new capital before the second quarter ended -- $50 million from its parent company and $12 million as a dividend from a real estate subsidiary.
As a result, the bank had about 50% more capital than necessary to remain classified "well-capitalized" by federal regulators, Downey said.
Washington Mutual said it too continued to "significantly" exceed the well-capitalized threshold, having recently raised $7.2 billion from private equity investors.
FirstFed Chairwoman Babette E. Heimbuch noted that her bank had twice the level of funds that regulators considered necessary to be well-capitalized. She said FirstFed's moves to cut back on risky lending and focus on more traditional loans, begun more than two years ago, meant that its condition would improve faster than that of competitors.
"While I'm not projecting [profits] the next few quarters, I'm also not projecting big enough losses to get us anywhere near being below the well-capitalized level," she said.
Nonetheless, investors fearful of bank failures pounded the stocks. FirstFed was down 92 cents to $3.99, Downey down 41 cents to $1.28, and WaMu fell $1.72 to $3.23. The Standard & Poor's 500 banking index had its worst one-day decline since September 1989, falling 9.8%.
Anne Martin, 56, wasn't taking any chances Monday. She went first to an IndyMac branch in Arcadia to liquidate a certificate of deposit, then planned to go to Downey Savings, where she intended to close another CD amid speculation it would be the next bank to fail.
"I'm going there after this," she said. "I know they did a lot of loans, and I'm afraid they're going to be caught up in the same situation."
At a Downey branch in Arcadia, Doris Crosby of Pasadena was transferring money from another bank, where it hadn't been insured, into her checking account despite hearing rumors that Downey was in trouble.
"I just have this feeling I'm jumping from one frying pan to another," Crosby, 82, said. "I just don't know what to do."
At IndyMac's branch in Arcadia, Don Dowd, 55, said he was worried he wouldn't be able to get access to all of his money right away. Dowd, a mechanic, said he had two CDs, each holding $111,000.
