Fed Cut Sends Dollar and U.S. Bonds Repricing Now.

U.S. policy and bond indexes recalibrated after the Federal Reserve cut rates by 25 basis points on Sept. 17. Traders quickly digested the move and Fed guidance, producing notable shifts across the dollar, nominal Treasury yields and bond indexes such as the Bloomberg U.S. Aggregate and TIPS benchmarks.

Key price updates

• U.S. Dollar (DXY): The dollar softened early after the Fed cut, trading around 97.1 in U.S. hours as markets parsed the Fed’s cautious tone.
• U.S. Treasury yields: The 10-year Treasury yield rose to roughly 4.07%, reflecting a post‑decision backup in nominal yields.
• Bloomberg U.S. Aggregate: The broad U.S. bond index ticked higher (previous close near 2,269.8), indicating modest inflows or reweighting into investment‑grade debt following the Fed action.
• TIPS: The Bloomberg U.S. TIPS index edged lower, implying relatively firmer real yields compared with nominal yields.

What drove the moves

The Fed’s quarter‑point cut was priced as a risk‑management step, but the central bank’s message left room for debate about the pace of future easing. That ambiguity prompted two main reactions:

Repricing of nominal yields

Even after a rate cut, nominal Treasury yields can rise if investors reassess the outlook for growth or future policy. The 10‑year’s uptick suggests some investors are demanding higher compensation for duration risk or positioning for different inflation or growth expectations.

Real yields and TIPS

TIPS underperformance (relative to nominals) points to a move higher in real yields — either due to cooling inflation expectations embedded in breakevens or to shifts in technical demand. When real yields firm while nominals also rise, breakeven inflation can compress.

Implications and what to watch next

• Follow incoming economic data (inflation prints, payrolls) that will shape expectations for further Fed action.
• Watch DXY and major pairs (EUR/USD, USD/JPY) for dollar direction; a steadier or weaker dollar can support U.S. bond inflows over time.
• Track on‑the‑run Treasury yields and Bloomberg index revisions for signs of sustained flows into or out of aggregate‑index bonds.
