Randal Quarles, who was appointed to the Fed by President Donald Trump in 2017, oversaw the Fed's bank supervision until his resignation in 2021.
Quarles did not respond to requests for comment on Friday. The Federal Reserve did not offer any further comment on criticism of its report and actions.
The report appeared only to harden long-set policy positions.
Democratic Senator Elizabeth Warren, who serves on the Senate Banking Committee and has led post-crisis reforms to rein in financial sector excesses, said the report "clearly identified" 2018 legislation among the "major contributors" to SVB's demise.
Patrick McHenry, the Republican chair of the House of Representatives Financial Services Committee, blasted the Fed report as a "thinly veiled attempt" to justify positions like those of Warren. In 2018, a significant number of Senate Democrats joined all Republicans in rolling back key provisions of the 2010 Dodd-Frank Wall Street reforms enacted after the global financial crisis. Among other things, the new law raised the threshold at which the most intensive oversight is required to $250 billion in assets, from $50 billion, a key point cited in the report. The reforms ultimately meant looser regulation and lower capital requirements at precisely the wrong time, according to the report. "While higher supervisory and regulatory requirements may not have prevented the firm's failure, they would likely have bolstered the resilience of Silicon Valley Bank," the report said. The collapse of SVB and Signature Bank last month burned a $23 billion hole in a government fund for deposit insurance, which officials are preparing to recoup in special fees expected to fall most heavily on the largest U.S. banks. It was unclear on Friday whether the Fed report made it more likely lawmakers could ultimately undo 2018's deregulation, with a narrowly divided Congress consumed by a battle over raising the government's borrowing limit to avert a default on U.S. sovereign debt in the coming months. According to the report, the 2018 law caused the Fed to raise the supervisory threshold for large banks, i.e. those smaller than the "global systemically important banks," to $100 billion in assets from $50 billion -- delaying stricter oversight of SVB "by at least three years." Had SVB been subject to the capital and liquidity requirements that existed before, the report said, SVB "may have more proactively managed its liquidity and capital positions or maintained a different balance sheet composition."
