A three-day, roughly 15 basis point climb in the 10-year Treasury yield put the long end at multi-year highs going into Friday's August consumer price report, and the market's own volatility gauges disagree about what that means.
The Treasury market did not wait for the data. The 10-year U.S. Treasury yield closed Thursday, September 10, at 4.95%, up from 4.83% on September 9 and 4.80% on September 8, a move of roughly 15 basis points across three sessions and the highest level in years. The 30-year closed at 5.37% and the 2-year at 4.56%. By Friday's pre-market hours the 10-year was quoted near 4.94%, with the 5-year at 4.73%.
That climb is the single most consequential price development heading into the August consumer price index, scheduled for release Friday at 8:30 a.m. Eastern, four business days before the Federal Open Market Committee meets September 15 and 16. As of Friday morning, interest-rate futures and prediction-market pricing put the probability of a September rate increase somewhere between roughly 60% and 70%, depending on the measure. That is a wide band, and the spread between measures is itself a signal of how unsettled the positioning is.
Two explanations, and they point to different trades
The first reading is straightforward. August producer prices came in hotter than expected on September 10. Diesel crossed $6 a gallon for the first time. Crude has spent weeks above $100 on the Iran conflict. Under this interpretation the bond market is pricing a hawkish inflation surprise before it prints, and Friday's CPI report will confirm what yields have already said.
The second reading is less discussed and harder to dismiss. A Treasury buyback operation the same day reportedly took in less than its stated maximum size. If part of the long-end move reflects who is and is not willing to hold duration at current levels, rather than what they expect inflation to do, then a CPI print in either direction may not settle the question at all.
The volatility signals split
The equity tape fell alongside yields. The S&P 500 closed Thursday at 7,591.70, down 0.58%. The Dow Jones Industrial Average closed at 52,064.10, down 0.60%. The Nasdaq Composite closed at 26,081.73, down 0.65%, and the Russell 2000 fell 1.04% to 2,890.95.
Yet the CBOE Volatility Index fell 4.09% to 17.12 on the same session, even as stocks declined. The MOVE index, which measures expected Treasury volatility rather than equity volatility, rose to 82.09. Equity investors were paying less for protection while bond investors were paying more. That divergence is not explained by the data available Thursday, and it is worth watching whether it persists after Friday's print.
Into Friday's open, equity index futures were modestly higher and yields had slipped slightly, though they remained near their multi-year highs. Whether the CPI report resolves the yield move or extends it will be visible within minutes of 8:30 a.m., and the answer determines whether next week's FOMC meeting is a live decision or a formality.
