Capital reform push could restore Wall Street’s edge in global markets

A proposed rollback of US bank capital requirements could give large American lenders new momentum in capital markets, helping them regain ground lost to nonbank firms while widening the competitive gap with European rivals.

The shift stems from a March proposal by the Federal Reserve that would ease capital reserve obligations for major US banks, marking what industry observers describe as a sharp reversal from years of increasingly restrictive post-crisis regulation.

The move follows a period in which banks amassed large Common Equity Tier 1 buffers in preparation for stricter Basel III “endgame” requirements that were expected to significantly raise capital thresholds.

According to a new Greenwich Associates report, the proposed changes could revive banks’ traditional role as key market intermediaries by freeing up balance sheet capacity that had previously been constrained by capital rules.

The report said the reforms may allow US banks to expand market-making operations, support greater trading activity and reclaim business from nonbank competitors that have gained market share in recent years.

Greenwich Associates said lower capital burdens could also create a structural advantage for US institutions relative to European banks, which continue to operate under tougher regulatory frameworks.

“Banks are likely to become much more active in fixed-income and other capital markets businesses if these rules are implemented,” the report noted.

Over-safe safeguards?

The proposal arrives amid a broader policy debate over whether post-2008 financial safeguards have gone too far in limiting banks’ ability to support market liquidity and economic growth.

Supporters of the changes argue current capital standards discourage banks from holding low-risk assets such as US Treasuries and reduce their ability to provide liquidity during periods of market stress. Critics, however, warn that easing requirements could weaken financial safeguards established after the global financial crisis.

Federal regulators in March proposed lowering aggregate capital requirements for the largest US banks by roughly 5%, according to multiple reports. The reforms would also reduce leverage constraints for some institutions and simplify aspects of the Basel III framework.

The Greenwich report suggested the reforms could particularly benefit US dealers competing against both European banks and fast-growing private credit and nonbank trading firms.

European rivals

European lenders, meanwhile, continue to face pressure over their ability to compete with Wall Street giants. Analysts have noted that stricter capital regimes and fragmented regional markets have limited the scale and profitability of many European investment banks compared with their US counterparts.

The debate has also exposed divisions among policymakers and regulators. Some officials argue banks already hold ample capital and that lowering requirements may primarily benefit shareholders through increased buybacks and dividends rather than translating into greater lending activity.

Others contend the changes could improve liquidity in key markets, including the US Treasury market, where regulators and industry participants have raised concerns about declining dealer capacity during periods of volatility.

The proposed rules remain subject to a public comment process before any final implementation decisions are made.
