OTS blamed the failure on a bank run following a June 26 letter to the OTS and FDIC from Sen. Charles Schumer (D., N.Y.) that expressed concerns about IndyMac's viability. Depositors withdrew more than $1.3 billion from the bank over the next 11 days, OTS said.
"This institution failed today due to a liquidity crisis," OTS Director John Reich said in the statement. "Although this institution was already in distress, I am troubled by any interference in the regulatory process."
Schumer, in a press conference Sunday, defended his letter, saying it offered "no new revelations" and only highlighted problems that had been festering for some time.
"The regulator here was asleep at the switch," Schumer said, according to the
. "The administration is doing what they always do, blaming the fire on the person who called 9-1-1."
