Fed kicks off hiking cycle with first rate increase since 2023

On September 16, the Federal Reserve approved its first interest rate hike in three years, raising the federal funds target range to 3.75–4.00%. The decision marked a definitive pivot from the easing stance that began in late 2025, with the dot plot indicating a median fed funds rate projection of 4.1% for year-end 2026. This move signaled that the central bank remains committed to containing inflation despite slowing growth signals.

10-Year Yield Touches Multi-Year Highs Before Reversing

Ahead of the FOMC meeting, the 10-year Treasury yield spiked to 5.011% on September 14, its highest level since October 2023, driven by concerns over persistent inflation and fiscal deficits. However, yields moved lower immediately following the Fed’s announcement, settling around 4.986% as traders digested the guidance that future hikes would be gradual rather than aggressive. The volatility highlighted the market’s sensitivity to any deviation from expected monetary tightening paths.

Short-End Yields Surge on October Hike Odds

The 2-year Treasury yield reached a multi-year high of 4.744% on September 18, reflecting a sharp repricing of near-term policy expectations. Following the Fed’s statement, futures markets increased the probability of another 25 basis point hike in October to approximately 58%. This steepening of the short end contrasts with the flatter long end, suggesting investors are skeptical that the Fed will maintain higher rates into 2027 without triggering a recession.

Global Bond Markets React to US Policy Shift

International bond markets mirrored US movements, with German Bunds and Japanese JGBs experiencing correlated sell-offs as global investors adjusted to the new "higher-for-longer" US rate environment. In Germany, media outlets noted that the 10-year US yield breaking 5% forced a re-evaluation of safe-haven asset valuations globally. Japanese press reported that while the 10-year US yield eased post-Fed, the Nikkei and local bond markets remained volatile due to fears of imported inflation from stronger dollar dynamics.

Local view

German financial media emphasized the impact of the Fed's hike on equity valuations, with finanzen.net noting that expensive stocks lose their primary support argument when risk-free rates approach 5%. The outlet argued that the "TINA" (There Is No Alternative) trade is effectively dead as cash and short-duration bonds offer competitive real yields.

In Japan, Nikkei reported that long-term US bonds continued to decline in price (yield rising) initially, but stabilized as the BOJ's own policy decisions set up a next market test. Bloomberg Japan cited a survey showing that over 60% of respondents expect the 10-year US yield to remain above 5% by year-end, driven by additional hike expectations.
