Big Banks Could Be Getting Very Good News From Regulators. Here's What You Need to Know.

In This Article:

After three large regional banks collapsed last year, the industry braced itself for blowback, not only from the public but from a regulatory perspective as well. Since the Great Recession happened roughly 16 years ago, banks have been waiting for the final phase of capital rules.

This framework, referred to as Basel III Endgame (BE3), would stipulate a wide set of requirements for the largest banks. These requirements include how much capital they would have to hold, what would count as capital, and how much capital banks would need to hold for certain types of loans and securities, among many other capital rules.

Following a lot of speculation about how the rules would shake out, it looks like banks could be heading for a positive outcome after Michael Barr, vice chair of supervision at the Federal Reserve, recently laid out his recommendations for BE3. Let's take a look.

Lower capital requirements than before

BE3 is an extraordinarily complex set of capital rules wrapped inside an extraordinarily complex process that has now taken close to two decades to hammer out. It's called BE3 because there have already been Basel I and II frameworks.

In July 2023, banking regulators rolled out their initial outline for BE3. It likely came out more restrictive -- and perhaps rightly so -- after the collapse of Silicon Valley Bank, Signature Bank, and First Republic.

The proposal called for as much as a 19% hike to aggregate common equity tier 1 capital ratios for all banks with at least $100 billion in assets. The CET1 ratio is a measure of core capital (and therefore loss-absorbing capital) to risk-weighted assets (RWAs). Essentially, banks have required CET1 capital ratios each year, and excess capital above these levels is used to originate and reserve for new loans, buy back stock, and issue dividends. Higher capital requirements typically lower banks' profitability and, as such, have less capital to return to their shareholders.

Other parts of the BE3 proposal included requiring most large regional banks to include unrealized securities losses in their CET1 ratios (the four largest banks in the U.S. already do this). This was a major issue that led to the downfall of the three banks that were taken into receivership last year.

These banks were in a situation that might have required them to sell bonds at a substantial loss to cover deposit outflows, which would have wiped out shareholder equity. Including unrealized securities losses in CET1 calculations provides a more accurate reflection of a bank's capital position. The initial version of BE3 also would have required banks to hold more capital for certain loans, such as mortgages.
