Bitcoin liquidity faces test as US tax deadline coincides with Fed meeting

The US estimated-tax deadline on September 15, 2026, is expected to shift cash into the Treasury, potentially tightening dollar funding and impacting Bitcoin liquidity. This movement of funds occurs as the Federal Reserve begins its policy meeting, creating a scenario where bank reserves may face pressure. While bank reserves recently increased to approximately $3.037 trillion as of September 9, tax payments typically reduce these reserves by moving balances from commercial banks to the Treasury, which can influence short-term financing and market risk appetite.
