Question / Objective
Read the current U.S. Treasury yield curve and monetary policy backdrop to assess whether conditions are historically tight or accommodative, and what that implies for borrowing, lending, and fixed-income markets.

Methodology
- 1.Pulled current Treasury yields across four maturities (3-month, 2-year, 10-year, 30-year) to plot the current yield curve shape.
- 2.Pulled the FRED T10Y2Y series directly (the Fed's own published 10Y-minus-2Y spread, not a value re-derived by differencing two separately-quoted yields) to state the current spread and to verify the exact historical inversion window by scanning for sign changes in the full daily series.
- 3.Pulled the effective federal funds rate and compared it against headline and core CPI inflation (same month) to approximate the current real (inflation-adjusted) policy rate.
Assumptions
- The real policy rate is approximated as (nominal fed funds rate − headline CPI YoY), a simplified approach rather than a precise Fisher-equation or inflation-expectations-based calculation.
- Only four points on the yield curve were plotted (3M, 2Y, 10Y, 30Y); a full curve would include additional maturities (1M, 6M, 1Y, 3Y, 5Y, 7Y, 20Y).

Yield-Curve Inversion History
Pulling the FRED T10Y2Y series directly (rather than differencing two separately-quoted yields) shows the spread was continuously negative from July 6, 2022 through September 5, 2024 — roughly two years — before returning to positive territory in early September 2024 and staying positive since.
Approximate Real Policy Rate
Effective fed funds rate (3.63%, Aug 2026) − headline CPI YoY (3.4%, Aug 2026) ≈ +0.2% real policy rate
A simplified approximation (not a forward-looking Fisher-equation calculation), using fed funds and CPI figures from the same month — suggests current monetary policy is only mildly restrictive rather than tightly restrictive.
Key Findings
- As of mid-September 2026, the yield curve is normal (upward-sloping): 3-month bills yield 3.97%, rising to 4.65% (2-year), 4.97% (10-year), and 5.34% (30-year).
- The 10-year/2-year spread (FRED T10Y2Y) is positive at +0.32 percentage points as of September 14, 2026, meaning the curve is not inverted — a reversal from the inverted curve that persisted, per a direct scan of the full FRED series, from July 6, 2022 through September 5, 2024 (roughly two years), historically one of the most closely watched recession indicators.
- The effective federal funds rate (3.63%) sits only modestly above headline CPI inflation (3.4%), implying a real policy rate of roughly +0.2% — suggesting monetary policy is only mildly restrictive at present, not tightly so.
- Core CPI (2.4%) is running a full percentage point below headline CPI (3.4%), indicating food and energy prices are contributing disproportionately to headline inflation.
Limitations
- • The inversion window (Jul 2022–Sep 2024) is precise to the day the T10Y2Y series crossed zero, but the spread hovered within ±0.04pp of zero for about two weeks around the crossover (late Aug–early Sep 2024), so treating that transition as a single hard date is a simplification of a genuinely choppy period.
- • The real-rate approximation is a simplification; it does not account for forward inflation expectations, which is the theoretically correct input for a real interest rate calculation.
- • This is a point-in-time snapshot (September 2026) and will move as new data is released — check the linked FRED/BLS sources directly for current figures.
