Before Iran became the main macro driver, the 10 year was already moving lower for the familiar reason. Growth was cooling, longer run inflation expectations were easing, and the market was starting to lean toward eventual Fed flexibility. January retail sales slipped 0.2%, and oil was already reflecting a softer demand backdrop alongside ample supply. That is a big part of why crude had been so low before the war shock. The March 6 payroll report confirmed a slowdown story the market was already leaning toward.
What This Chart Is Really Showing
The 5 year 5 year forward is not a read on next month’s CPI or this week’s gasoline price. It is the market’s estimate of average inflation over the five year period that begins five years from now. So when that measure falls to around 2.15%, near the lowest level since April, the market is saying the long run inflation regime still looks contained. It is treating the current move as a shock, not as a lasting reset higher in inflation.
Why Long Term Inflation Expectations Are Falling Even With Oil Exploding
Because the market thinks the Iran and Strait of Hormuz shock is more likely to hurt growth than create a durable inflation spiral. Oil has surged violently. WTI moving from about 63.55 a month ago to 90.90, while Brent pushed into the low 90s absolutely matters for headline inflation, freight, insurance, and consumer psychology.
But energy shocks often work like a tax. They hit households first, squeeze margins, tighten financial conditions, and weaken demand later. If the economy was already softening before the shock, the medium term effect can be weaker growth rather than permanently hotter inflation. That is why long term inflation expectations can keep falling even while crude is exploding higher.
Why The 10 year Is Trading On A Different Dynamic
The 10 year is not just an inflation expectations instrument. It is also a real yield trade, a Treasury supply trade, and a duration risk trade. That is the key. Long term inflation expectations can drift lower while the 10 year stays elevated because the inflation problem and the Treasury market problem are no longer the same thing.
A big piece of the 10 year is still real yield. Another piece is the premium investors demand to absorb heavy sovereign issuance and hold long duration paper in an environment full of geopolitical uncertainty. That is why the 10 year can sit around 4.13% even while the far forward inflation story looks calm.
How Iran And Hormuz Changed The Story
Iran changed the character of the move. Before the conflict escalated, lower oil and lower yields were telling roughly the same macro story. Then Hormuz turned oil from a weak demand signal into a live supply shock. That is the split the bond market is now pricing.
The oil shock is inflationary now because it lifts energy costs and disrupts trade. But it can also be disinflationary later if it crushes demand hard enough. The 5 year 5 year forward is reflecting that longer horizon. The 10 year is reflecting the uglier middle period where inflation risk, duration risk, and sovereign supply are all alive at the same time.
The March 6 payroll report fits into that sequence as confirmation, not as the starting point. It reinforced the idea that the economy was already losing momentum just as the energy shock hit.
What Likely Brings The 10 Year Down
The 10 year comes down in a lasting way only when one force clearly wins. Either Hormuz de escalates and the oil premium collapses, or growth breaks hard enough that real yields roll over and the market starts pricing a much more aggressive Fed response.
Until then, the market stays split. Long term inflation expectations are falling because the market thinks the shock is temporary. The 10 year is staying elevated because it still thinks the duration and funding problem is not.
