US regulators are set to make public confidential details of their supervision of Silicon Valley Bank and Signature Bank in the operation up to the local lenders’ sudden collapses last month, while another large financial institution’s survival struggle develops in the present moment.

In consecutively reports due on Friday, the Federal Reserve and the Federal Deposit Insurance Corporation (FDIC) are also anticipated to propose an array of fixes that could pave the way for tougher US bank-sector regulation and supervision in the future – shifts that are probable to draw pushback from an industry willing to keep the regulating releases it received a few years ago.

Financial regulators shut down Santa Clara, California-based SVB on March 10 in the most significant bank failure since the financial crisis a decade and a half ago, after trembled consumers dragged $42 billion in funds in one day and waited up to cash out another $100 billion the next day, indicating the biggest banking run in US history.

Signature in New York situated in New York, was shut down two days later after losing 20% of its deposits in the hours following SVB’s failure and facing a flood of withdrawal requests that weekend.

To stem further contagion, US authorities opened up new emergency lending to banks on Sunday, committed to making SVB and Signature Bank investors whole, and provided broad confirmation of more safeguards should the financial system be subjected to additional stress from other bank failures.

In the weeks that followed, the financial sector stabilized. However, turmoil resurfaced this week after the First Republic reported a drop in deposits of more than $100 billion in the second half of March.

A revelation on Wednesday that the FDIC, First Republic’s regulator, may soon reduce the bank’s secret rating, limiting its ability to borrow from the Fed, has stoked uncertainty over the lender’s survival.

Fed Vice Chair of Supervision Michael Barr, who oversaw the US central bank’s SVB examination, has offered some information on the bank’s demise, including executives’ failure to handle “bread and butter” liquidity and interest-rate risks, which he claims played a significant part in its demise.

And he has stated that the confidential supervisory conclusions of bank examiners, who have identified some of the hazards at the fast-growing, tech-focused lender as early as 2021, will be included in Friday’s report.

However, little is known about the interactions between SVB’s management and supervisors, even as the bank built up enormous amounts in long-term assets that lost market value as short-term rates of interest rose, despite the fact that under the Fed’s rules for banks of its size, it did not have to the water up capital to make up for those unrealized losses. It is also unknown to what extent investigators focused on the bank’s huge amount of uninsured deposits, an important component of the run that brought it down.

Signature and First Republic were both largely reliant on uninsured deposits, albeit the majority of the money still in accounts at the ailing San Francisco-based lender now falls outside the FDIC’s insured deposit limit of $250,000 per client, according to its quarterly report.

FDIC Chair Martin Gruenberg has not supplied much information on Signature’s oversight, which, like SVB, has grown dramatically in recent years.

Analysts suspect that the banks’ quick expansion may have outpaced management’s ability to plan for the tighter scrutiny that banks with more than $100 billion in assets are subject to, as well as supervisors’ capacity to oversee risks appropriately.

US Representative Patrick McHenry, the Republican chairman of the House Financial Services Committee, and Representative Maxine Waters, the ranking Democrat on the committee, have asked the Government Accountability Office to look into the bank collapses. Both the House and Senate are anticipated to hold additional investigations on the banks and have stated a willingness to hear from the prior CEOs of SVB and Signature.

Barr told Congress in March that he believes it is appropriate for independent evaluations of the Fed’s monitoring of SVB to be conducted as a supplement to the US central bank’s own review.
