In a "vacuum" environment lacking clear technical support, long-end Treasury yields are reinforcing their own upward move, running counter to the direction of oil prices.
Long-dated U.S. Treasury yields are showing upward momentum that is independent of traditional drivers. At the close of a stressful trading week, the 30-year Treasury yield broke above 5.5%, hitting its highest level since 2004, while oil prices fell on the same day 鈥?a divergence that has put the market on alert.
On Friday, the 30-year Treasury yield rose as much as 5 basis points intraday to 5.53%, holding above 5.49% at the close, up about 2 basis points from the previous day. The 10-year Treasury yield also refreshed a multi-year high, breaking above 5.22%. Notably, the 30-year yield was below 5% in early July this year and has surged by more than 50 basis points in just a few months.
At the same time, shorter-dated yields, which are more sensitive to Federal Reserve policy expectations, moved lower, with the 2-year yield falling about 7 basis points on the day. The divergence between long-end and short-end yields has caused key curve segments 鈥?including the 2-year to 10-year and 5-year to 30-year spreads 鈥?to rebound significantly and steepen from more than one-year lows earlier in the week.
"Vacuum" State: Lacking Technical Support, Yields Reinforce Their Own Rise
A notable feature of this round of long-end yield increases is the absence of clear technical resistance levels.
"People don't have a real technical level to latch onto, and that leaves the market in a kind of vacuum," said Izaac Brook, U.S. rates strategist at RBC Capital Markets. "That has allowed yields to drift continuously higher."
This "vacuum" characteristic means that, without a strong fundamental catalyst, the inertia of rising yields is difficult to interrupt. The direct trigger that pushed yields higher on Friday was the University of Michigan's consumer sentiment index 鈥?although the index fell to a four-month low in September, it was still better than economists' expectations, suggesting that the U.S. economy and businesses are withstanding the high-rate environment better than expected.
Oil Divergence: The Logic Behind Higher Long-End Yields Has Moved Beyond Energy Drivers
More noteworthy is that Friday's rise in long-end yields clearly ran counter to the direction of oil prices.
U.S. benchmark West Texas Intermediate crude futures fell 2.3% on the day to $92.41 a barrel. Previously, oil prices had been the main driver of intraday swings in Treasury yields, reflecting supply shocks caused by the Middle East war. On Friday, however, that linkage broke down.
Andrew Hollenhorst, an economist at Citigroup, noted in a report that "because Fed hikes are a direct response to higher energy prices, the market is currently unable to price a clear near-term cap on the hiking path." This means that even if oil prices pull back in the short term, concerns about inflation persistence and the Fed's tightening path have not dissipated, giving long-end yields upward support independent of oil.
Short-End and Long-End Divergence: The Market Is Skeptical That the Front End Is Overpriced
The simultaneous decline in short-end yields reflects divisions within the market over the path of interest rates.
Earlier in the week, short-end yields had surged to multi-year highs alongside expectations for a September Fed hike 鈥?the first since 2023. But on Friday, market sentiment shifted.
"The front end is already priced too much," said Monty Gandhi, rates strategist at SMBC Group. "Short-term investors are looking to buy the front end, believing that any further bearish sentiment should be expressed in the belly of the curve or through a 'higher for longer' stance."
Morgan Stanley rates strategists, meanwhile, raised their Treasury yield forecasts based on the bank's latest upward revision to its Fed tightening projection, and noted that market pricing of the Fed policy path can explain most of the move in 10-year yields.
Activity in the Treasury futures market also corroborated the steepening trend. Shortly before 10 a.m. New York time, a large simultaneous block trade involving 5-year Treasury futures and Ultra Bond futures appeared 鈥?the price levels indicated the trade was a buy of 5-year futures and a sell of Ultra Bond futures, consistent with profit-taking on curve-steepening bets.
Overall, against the backdrop of the Fed restarting its hiking cycle, energy prices supporting inflation expectations, and economic resilience exceeding expectations, long-end Treasury yields have entered an upward channel without a clear cap. For fixed-income investors, how to re-anchor duration risk in this "vacuum" environment is becoming the most urgent question of the moment.
