The Oil–Bond Link Is the Tightest on Record. Mackintosh Asks Whether Traders Are Overdoing It

A tanker off the French coast has become the bond market’s favorite economist. Oil rises, yields rise, stocks fall — and the reflex is now so well drilled that by James Mackintosh’s measure in his Streetwise column, a 100-day correlation of daily moves in the 10-year yield and Brent futures, the two tracked each other this month more tightly than ever recorded. This week fit the pattern. Then he turns the question around: suppose traders are wrong to lean on oil this hard. In that case, he writes, yields may have overshot, and so may everything priced off them, from government borrowing costs to stocks.

The short-rate part is easy. Dearer oil is pushing inflation up, and Kevin Warsh’s Fed has decided it can’t look through that, so futures price a more than 50% chance of four more hikes by the end of next year. An oil spike lifts the inflation rate once, he notes, and the effect wears off as soon as the price stops climbing. Yet the link is tighter at the long end than the short, and holds even in a synthetic bond starting five years out, near-term yields removed. “It makes no sense that what happens to oil today should affect the 10-year,” Vítor Constâncio, the former ECB vice president, told him. The 10-year closed Friday at 5.18% in the Journal’s tables, a 19-year closing high.

Three theories and a footnote from 1990

Mackintosh offers theories rather than a verdict. One: governments answer expensive oil with subsidies, tax cuts and export bans, and pay for them with bigger deficits or slower growth. Two: oil is high because AI spending has the economy booming, so faster expected growth lifts oil and yields together, with the supply shock from the Iran war tightening the link. Three: long bonds are mispriced — Alan Blinder, the former Fed vice chairman, noted three decades ago that daily moves in one-year rates tracked the implied one-year rate 29 years out. He thinks there’s more to it than chance: the correlation was also very high in the 1990-91 Gulf War and in 2010, 2012, 2016 and 2020. His own position: Treasury yields look attractive to him, gilts more so, chiefly as insurance should the AI trade fail — though he worries, like everyone, about U.S. debt, a slow Fed and oil.

Our read

We’ll take the diagnosis and only part of the prescription. If the oil–bond link is overdone, long yields could retreat when oil settles — the Journal’s futures table prices WTI at $92.41 for November but $74.00 for December 2027 and $69.32 for December 2028, a crowd price rather than a forecast. The desk’s answer is that you don’t have to make that bet to get paid: in the Journal’s tables the 13-week bill auctioned at 4.015% this week and the 2-year closed at 4.862%, and safe money in Treasury bills and floating-rate paper (SGOV, USFR) collects most of the yield without the long end’s drama. Long duration stays on the avoid list (IN02).

Energy is the other half of the same trade, and it’s why the desk holds it as the hedge: if oil and yields keep rising together, the barrel pays for what the bond costs. Valero (VLO) was added this weekend at 1.5% in ten model books; its trim signal is a White House move toward restricting diesel exports — policy, not price. This week’s floated ban was played down to voluntary; nothing is published or ordered, and if a plan is published the trim decision gets made in writing. What you shouldn’t do is dump or chase 10-year paper on an oil headline. Set the duration of your safe money on your own dates, and let the tanker do the day trading.
