US inflation came in hotter than expected in October, with headline and core CPI both 0.1 percentage point above forecast. For those managing US dollar cash, the implications extend beyond the inflation print itself. Expectations for Federal Reserve policy influence market interest rates and, ultimately, the rates banks are prepared to offer on USD deposits.

What drove the increase

Shelter rose 0.3% and accounted for more than 30% of the overall monthly increase. Food rose 0.5%, with food at home up 0.4% and food away from home up 0.5%. Energy rose a further 0.7%, well below September's 5.2% jump.

There is no comparable year-on-year rate for October, as data were not collected in October 2025 during the US government shutdown. That gives this month's figures greater significance than usual.

Market reaction

The reaction was immediate, with the US 10-year Treasury yield nearly touching 5% at the time of writing, up approximately 12.5bps on the day so far.

Ahead of the data, markets were already expecting persistent inflation to keep the Federal Reserve on course for a December rate increase. A stronger-than-expected core reading adds to that picture, and attention now turns to whether the Fed maintains a restrictive stance.

The key question is whether the move in yields and the US dollar holds as markets digest the detail.

What it means for you and your clients

For trustees, advisers and treasury teams managing US dollar cash, a few practical points stand out.

• Deposit rates do not move in lockstep with the data. Banks price Fixed Term Deposits with reference to wholesale funding conditions, their own funding needs and the interest rate and swap curves, so the same deposit can be priced quite differently from one bank to the next.

• Expectations can shift quickly. As the Treasury yield reaction shows, market pricing can move within minutes of a data surprise, and the rates available across banks and tenors can change with it.

• Choice matters. Being able to compare banks, currencies and tenors side by side helps clients make informed decisions about where, and for how long, to place cash.

Through Flagstone International, eligible clients can access a range of deposit and Money Market Fund options across multiple banks and asset managers through a single platform. This helps treasury teams compare opportunities, diversify cash and manage liquidity without establishing individual relationships with every provider.
