Global banks prepare for Basel III rollout on July 1, 2025, borrowing costs expected to rise

The financial system is about to undergo a major transformation. The Basel III Endgame regulations, set to begin on July 1, 2025, will increase capital requirements for banks with over $100 billion in assets, forcing them to hold more reserves and limit lending. The Federal Reserve, along with the Office of the Comptroller of the Currency (OCC) and the Federal Deposit Insurance Corporation (FDIC), finalized these reforms in July 2023, marking a new era of financial regulation.

The new rules will raise common equity tier 1 capital requirements by 16 percent, affecting large financial institutions that play a critical role in credit markets. Banks will be required to include unrealized gains and losses from securities in their capital ratios, making risk management more stringent.

Credit availability is expected to shrink. With banks forced to hold more reserves, lending activity will slow down, particularly in commercial real estate, private equity, and corporate debt markets. Borrowers will likely face higher interest rates, as financial institutions adjust to the new regulatory framework.

Global banks are preparing for impact. The Bank for International Settlements (BIS) has confirmed that most member jurisdictions have finalized their Basel III rules, ensuring a coordinated global rollout. European and Asian banks are already adjusting their balance sheets, anticipating tighter liquidity conditions.

The Federal Reserve’s role is crucial. As a member of the BIS, the Fed will enforce these capital requirements, despite pushback from Wall Street. Major banks have lobbied against the reforms, arguing that stricter rules could stifle economic growth. The Treasury Department has advocated for looser regulations, creating a policy conflict that could shape financial markets for years to come.

The coming months will reveal the full impact of Basel III. If banks cut back on lending, businesses and consumers could face tighter credit conditions, leading to slower economic expansion. The question remains whether regulators will adjust policies to prevent a credit squeeze or hold firm on financial stability measures.
