The conflict in the Middle East has unsurprisingly led to higher oil prices, a stronger U.S. dollar and risk-asset volatility. Less expected, however, has been the rise in global yields, particularly in markets that are normally considered safe havens in times of geopolitical stress. U.S. yields are a glaring example, rising around 20bp from their levels on Friday, February 27, the day before hostilities began. We looked at this topic last week, after just one business day of trading during the conflict.
At the time, we argued that higher oil prices pushed yields higher by lifting inflation expectations. A quick decomposition using current (as of this writing) levels shows the 10y breakeven inflation rate (TIPS, or the difference between nominal bond yields and the inflation-linked security of the same maturity) has risen just over 10bp, while the 10y TIPS yield is up a little more than 8bp. The latter move indicates marginally higher real yields over time, probably reflecting muted expectations of higher interest rates in response to rising oil prices. Indeed, the December 26 OIS market shows that investors expect just 38bp of tightening for the remainder of the year, compared to around 61bp priced in just before the conflict started.
In Exhibit #1, we show the 10y breakeven inflation rate and the 1y inflation swap. The former, which measures annual average inflation expectations over the next decade, is still very close to the range in which it has been trading for several years, roughly between 2.2% and 2.5%. Its move higher due to higher oil prices has been modest and does not indicate a breakout in long-term inflation expectations. The shorter-term measure, with a 1y horizon, has moved much more, from around 2.5% before the conflict began to nearly 3%. This 0.5% increase is materially higher but remains well contained – certainly below levels seen in the months after last April’s tariff announcements.
Obviously, the length and intensity of the conflict will determine how high crude prices go and how long they stay elevated. For now, with developed economies already facing sticky inflation, the path of inflation expectations will be key for bond yields. We understand why bonds haven’t rallied but note that with the U.S. 10y yield now trading between 4.10% and 4.20%, it remains below levels seen in early 2025 and in late January, when yields touched nearly 4.3%.
iFlow shows similar behavior among investors and Exhibit #2 shows five straight days of cross-border outflows from USTs. This is not unique to the U.S. We suspect yields are rising globally, especially in developed markets, owing to the same inflationary dynamics at work in the U.S. For as long as oil prices reflect supply concerns, we expect yields to stay well above where they were before the start of the conflict.
