US Treasuries and the Fed: Yields, Auctions, FOMC — 2026-09-25

Top developments

10-year yield rockets to 19-year high above 5.1%

On Wednesday, September 23, the 10-year Treasury yield surged to 5.093% (intraday above 5.1%), its highest level since July 17, 2007, after new services and manufacturing data showed strong business activity and intensified inflation concerns, boosting expectations of further Fed rate hikes. The squeeze in yields raises financing costs across the economy and strengthens the case for watching how far term premium reconstruction can run.

Fed's fresh hiking cycle keeps pressuring the long end

The Fed raised rates on September 16 — its first hike since 2023 — with Chairman Warsh signaling resolve on inflation, and the September dot plot projected a fed funds target of 4.00%–4.25% at yearend 2026 and 2027. Several Fed officials have since advocated another hike, keeping rate expectations and the 10-year yield elevated into week's end. Higher-for-longer pricing is the key driver behind the curve and term premium dynamics this week.

Sell-off spreads across the entire bond market on weak auction demand

Handelsblatt reported on September 23 that weak demand at a US Treasury auction and growing fears of a tighter Fed rate path pushed yields to new yearly highs, dragging a sell-off across the global bond market. This is a warning sign for future Treasury financing: soft demand at auctions amid a heavy issuance calendar can force further term premium increases.

Higher yields deliver a "reality check" on a hot economy

CNBC analysis (September 24) argues elevated Treasury yields will complicate both Fed policy and Treasury financing, as government debt costs leaped higher on September 23 amid multiple overlapping pressures. With the 10-year rising for a sixth consecutive week and oil above $100, fiscal financing costs and the deficit trajectory are back at the center of market debate.

Local view

• Germany — finanzmarktwelt.de runs an analysis asking whether Fed chief Warsh is "losing control" as US yields keep climbing and the debt burden weighs, reflecting European worries that Fed interventions are "running into the void."
• Germany — wallstreetONLINE frames the yield shock as a bond-market earthquake hitting equities: 19-year-high yields with oil over $100 and weak gold left only 7 stocks keeping pace on the DAX and Wall Street.
• Japan — Nikkei argues the 5% era for long-term US yields may be a "new normal," citing economic expansion and concerns over fiscal largesse — a notable view from the largest foreign holder of Treasuries.
• Japan — Nikkei also reported long bonds extending losses with the 10-year at 5.02% on additional Fed hike expectations.

Context & numbers

• 10-year yield: 5.093% intraday September 23, highest since July 17, 2007 (19-year high).

On the radar

• More Fed speeches: another Fed official advocated another hike this week — watch for further hawkish commentary and its effect on the 2s10s curve.
• Upcoming Treasury auctions: check TreasuryDirect for this week's bill and note announcements; the weak-demand signal from the last coupon auction bears monitoring for tails.
• Trump–Xi meeting agenda including trade and oil — headline risk for inflation expectations and yields.
• CME FedWatch pricing of the next FOMC move — probabilities will be live data to watch as more officials speak.
