Société Générale Identifies Mispriced U.S. Treasuries as Bond Yields Drop

Société Générale analyzed the U.S. government bond market following a broad decline in bond yields, identifying specific U.S. Treasury securities that trade at notable discounts or premiums compared to modeled fair values. The benchmark 10-year U.S. Treasury yield (TVC:US10Y) stands at 5.081%, while the 2-year yield (TVC:US02Y) is at 4.715% and the 30-year yield (TVC:US30Y) is at 5.426%.

The relative-value study mapped individual bonds against a mathematical spline yield curve to evaluate pricing discrepancies among similar maturities. Securities found to offer higher yields than the model baseline included a 2.5% Treasury bond maturing in February 2045 yielding 5.485%, along with notes maturing in May 2036 and August 2036. Conversely, a 4.375% bond maturing in February 2038 yielded 5.010%, trading roughly 7.3 basis points below fair-value estimates and marking it as relatively expensive.

Understanding relative mispricing offers fixed-income investors ways to navigate the market without relying solely on directional rate bets. Discrepancies can emerge due to differing liquidity, seasonal demand, or trading flows. Moving forward, market participants will watch whether these yield differences narrow toward their historical averages or widen further across intermediate and long-term maturities.
