**The 30-year Treasury yield has traded in a rising range near 5.23–5.40% through mid-September 2026, with the monthly low so far occurring early in the period before climbing to close around 5.35–5.36% on September 15.** Sticky August CPI (+0.4% MoM, +3.4% YoY, driven by energy and shelter) and resilient growth data have reinforced expectations that the Federal Reserve will begin tightening again. Markets price a high probability of a 25-basis-point hike at the September 15–16 FOMC meeting, lifting the federal funds target from the current 3.50–3.75% range. Geopolitical tensions have pushed oil prices higher, adding to near-term inflation pressures and supporting elevated real yields. Longer-term rates also reflect firmer growth expectations and reduced odds of near-term easing, outweighing any term-premium effects. The upcoming FOMC statement and dot plot will be the dominant near-term catalyst, with any hawkish surprise likely to keep downward pressure on yields limited for the remainder of the month.
