Oil Prices Down Over 30%—Why Are Treasury Yields Unmoved?

WTI crude has dropped over 30% since mid-May, yet the 10-year Treasury yield still sits near 4.5% — historically, an oil decline this large drags nominal rates down with it, but this time the transmission chain snapped midway.

01

Oil crashed — why aren't rates following?

Historically the chain runs: oil falls → inflation expectations drop → nominal yields follow. This time, breakeven inflation (the market's pricing of future inflation) did fall by 20–30 basis points, right on cue.
But real yields — borrowing costs after stripping out inflation — kept climbing, fully offsetting and then overriding the drop in inflation expectations.
This means → nominal yield = inflation expectations + real yield. One leg fell, the other rose by more — the sum barely moved. The driver of rate pricing has switched from inflation expectations to real yields.
02

What kind of oil decline is this?

The prior run-up in oil mainly reflected a geopolitical supply-risk premium — Middle East conflict and potential disruption at the Strait of Hormuz. As ceasefire progress and shipping-recovery expectations grew, that premium was squeezed out.
In plain terms = oil fell because war risk is fading, not because the economy is weakening.
This reflects a "benign disinflation": price levels come down, but no signal of slowing growth is attached. The bond market has no reason to seek safety, so yields stay put.
03

Why are real yields rising instead?

According to GTJAI macro research, the core reason is a shift in the Fed's policy framework. Under new Chair Waller, the Fed has built a reaction function that prioritises price stability more aggressively — lower tolerance for inflation, higher tolerance for growth volatility.
This means → markets have re-priced the policy-rate path upward; "higher for longer" is now the base case. Weaker forward guidance raises uncertainty, pushing up the term premium (the extra return investors demand for holding longer-dated bonds).
In plain terms = investors used to believe the Fed would cut rates quickly whenever the economy stumbled — the so-called "Fed put." That belief has visibly weakened; policy will not pivot to easing over short-term turbulence.
04

What is the yield curve saying?

Since oil peaked, the curve has exhibited bear flattening: short-end rates rose with the re-priced policy path, while the long end held relatively steady as inflation expectations eased — the term spread narrowed sharply.
In plain terms = short-term borrowing got more expensive (the Fed is in no rush to cut), long-term borrowing barely moved (long-run inflation risk is receding) — squeezed from both ends, the curve flattens.
Within the inflation-expectations structure, the front end fell far more than the back end, signalling that markets view this oil shock as a temporary factor, not a lasting deflationary trend.
05

What would it take for Treasury yields to actually fall?

GTJAI concludes: 10-year breakeven inflation is already back near the target range. Relying on further oil declines to push inflation expectations even lower is a game of diminishing returns.
This means → for nominal yields to drop materially, cheaper energy alone is nowhere near enough — the market would need to see a clear weakening in demand, or a fresh pivot in the Fed's policy framework.
"Oil crashes, bonds don't rally" is not a cross-asset pricing failure. It is the pricing mechanism itself shifting: the dominant variable now is real yields running at a higher centre — and that shift is anchored by a Fed that prioritises fighting inflation over cushioning growth.
