Dollar funding / liquidity conditions
Updated
What it is
Dollar funding refers to the cost and availability of borrowing U.S. dollars overnight in short-term money markets, chiefly the repo market, where cash is lent against Treasury collateral. The New York Fed publishes the Secured Overnight Financing Rate (SOFR) each business day as the benchmark measure of this cost. A spike in repo rates relative to the Fed's policy rate signals stress in the plumbing banks, dealers and money-market funds rely on.
Why it matters lately
On September 17, 2026, repo rates spiked toward 10% — an unusually large dislocation versus the normal 10-20 basis-point intraday range — driven by corporate tax-date cash outflows and heavy Treasury settlement needs. The Fed responded with daily repo operations injecting roughly $52 billion to $75 billion-plus from September 17 through September 27, 2026. This came one day after the Fed's September 16 hike to 3.75-4.00%, its first increase since 2023, which tightened dollar liquidity further just as Treasury yields hit 19-year highs.
