The question of when US Treasury yields will finally peak remains one of the hardest puzzles for the market to solve right now.
Fresh quantitative cross-asset research from Citi shows that a pullback in oil prices is almost a necessary precondition for Treasury yields to reach their peak, and the ongoing geopolitical tensions are keeping crude lofty, which suggests the ultimate peak in yields may still lie ahead.
According to the research, the front-end breakeven inflation rate and oil prices are the most reliable leading signals in history for calling a top in the 10-year Treasury yield. Yet the breakeven inflation rate is still strengthening rather than easing, and the US Dollar Index (DXY) has recently resumed its climb, both of which point to a yield peak that has not yet formed. At the same time, other market signals such as widening high-yield credit spreads and cyclical stocks underperforming defensive names already match the profile of a yield peak, leaving the current signals contradictory and the direction very difficult to judge.
On the asset allocation side, Citi's cycle model is currently following a "late-cycle" playbook 鈥?underweight equities and credit, and overweight bonds (excluding Treasuries) and commodities. The global macro strategy team remains neutral on duration, prefers to receive the European Central Bank versus Federal Reserve rate differential, and favors equities over credit.
Oil prices are a necessary condition for a yield peak
Citi's quantitative global macro strategy team, analysts Alex Saunders and Vinh Vo, reiterated their cross-asset analytical framework in the report and added three new rate selloff episodes of more than 70 basis points, with the core conclusions largely unchanged.
Historical data show a clear lead-lag pattern in cross-asset performance before the 10-year Treasury yield tops out. The front-end breakeven inflation rate typically rolls over one to two months ahead of the yield peak, while a peak in oil prices is almost a necessary precondition for yields to peak. By contrast, the 2-year real rate tends to keep rising even after the yield peak, making it a lagging indicator.
At present, the strengthening trend in the breakeven inflation rate has already appeared, but the crucial "rollover" signal has yet to form. Citi notes that persistent geopolitical uncertainty is keeping crude oil prices elevated, making the timing of an oil price peak hard to pin down. Against this backdrop, any forecast for a yield peak can only be pushed further out.
Which signals work and which do not
Citi's research systematically reviews the indicators commonly used by the market and clearly separates those with leading value from those that tend to mislead.
Among the effective signals, flattening of the 5-year to 30-year Treasury curve (5s30s) usually appears about a month before the peak, but that trend has reversed over the past 25 trading sessions, leaving the signal muddled. Widening high-yield credit spreads and the relative outperformance of low-default-risk stocks also align with the historical pattern around yield peaks. In addition, quality stocks typically perform strongly in the 200-day window around a yield peak, which has recently been evident, while growth stocks often peak before the yield peak and then keep lagging.
Among ineffective or lagging signals, Citi explicitly states that both core CPI and headline CPI year-on-year readings are lagging indicators, and a recently hotter CPI print does not rule out the possibility that yields have already peaked. The 2-year real rate likewise does not reverse at the yield turning point. The VIX index offers almost no value for timing a yield peak, though historically it tends to drift lower after a peak is confirmed.
Current signals contradict one another
Citi concedes that, after comparing current market dynamics with historical patterns, the resulting signals are clearly in conflict, making a definitive directional call difficult.
On one hand, cyclical stocks have weakened relative to defensives for two to three consecutive months and high-yield credit spreads are widening, both consistent with the market profile after a yield peak. On the other hand, the breakeven inflation rate is still strengthening, the US Dollar Index has resumed its rise, and oil prices remain supported by geopolitical factors, all of which together suggest the ultimate yield peak may still lie ahead.
Citi believes that positive progress on the geopolitical front 鈥?especially after the midterm elections 鈥?would significantly raise the probability of an oil price peak, in turn creating the conditions for a sustained pullback in Treasury yields. Until then, the near-term path of yields will remain highly uncertain.
Under this framework, Citi's cycle model has shifted into a "late-cycle" mode. Specifically, the model is underweight equities and credit, overweight bonds (but not Treasuries) and commodities, and has recently cut equities further to underweight. The global macro strategy team remains broadly neutral on duration, prefers the ECB-versus-Fed rate differential in rates strategy, and prioritizes equity exposure over credit. The core logic of this allocation is that, with the yield-peak signal still unclear and neither oil prices nor the breakeven inflation rate having decisively rolled over, a neutral rather than aggressively long stance on Treasuries is the more prudent choice.
