This market will resolve to "Yes" if the Treasury 30-year yield is lower than the listed value for any date between September 3, 2026 and September 30, 2026. Otherwise this market will resolve to "No". This market will resolve as soon as the Treasury 30-year yield is lower than the listed value, or once data is available for September 30, 2026. If no qualifying value is published and data is not available for September 30, 2026 by October 14, 11:59 PM ET, this market will resolve to "No". The resolution source for this market is the Department of the treasury, specifically the data listed under "Daily Treasury Par Yield Curve Rates" for the column "30 Yr" (see: https://home.treasury.gov/resource-center/data-chart-center/interest-rates/TextView?type=daily_treasury_yield_curve&field_tdr_date_value=2026).Recent surges in the 30-year Treasury yield to approximately 5.35% as of September 11, 2026, reflect elevated term premium demands amid heavy federal debt issuance, persistent fiscal deficits near $2 trillion annually, and competition for capital from AI-related corporate borrowing. Oil price spikes near $110 per barrel have reinforced inflation concerns, while Treasury auctions have cleared at multi-year highs with solid but not exceptional demand. Market-implied odds for near-term Fed tightening have risen ahead of the September 15-16 FOMC meeting, even as some economic releases show moderating pressures. Softer CPI or labor data could ease yields by signaling policy restraint, whereas stronger growth or energy-driven inflation prints would likely sustain the upward bias through month-end resolution.
