This is a follow-up to The Hidden Overall Commander of Operation Epic Fury May Have Been the Treasury Secretary. That piece argued that the economic logic of the operation pointed to Scott Bessent as the architect of its financial constraints. One week later, the framework still holds. But the scenario it depended on is under severe strain.

The original thesis rested on a single pivot point: the Strait of Hormuz would reopen quickly, Iranian oil infrastructure — deliberately preserved — would become the basis of a deal, and oil prices would fall far enough to solve five of Bessent’s problems simultaneously.

That pivot has not arrived. And the costs of waiting are compounding.

Where the equation stands

When Operation Epic Fury launched on February 28, the US 10-year Treasury yield briefly touched 3.96% on safe-haven demand. Within 48 hours, that bid exhausted. As of March 6, 21:00 JST, the 10-year yields 4.173%.

The original piece identified two critical thresholds. At 4.15%, mortgage rates stop improving and start deteriorating. At 4.25%, the 30-year mortgage rate pushes past 7% and housing affordability becomes a political crisis before November’s midterms.

The first threshold has been breached. Mortgage rates in the United States are now getting worse, not better. The distance to the second threshold is roughly five basis points.

Brent crude is at $89.21 as of this writing, up 5.82% on the day and approximately 18% for the week. VIX is at 25.55. USD/JPY sits at 157.95, yen still weak. The Nikkei closed at 54,830, down 1.61% — the relief rally of March 5 fully erased.

Five sellers, one buyer

In the original piece, Japanese lifer repatriation was a risk to model. It has since become a confirmed forced flow.

The Ministry of Finance reported ¥3.42 trillion in net foreign bond sales in February alone — the sharpest monthly exit in over a year, and more than the entire Q4 2025 total compressed into a single month. Japan’s 30-year JGB yields 3.396%. The 40-year reached 4.24% in January. Against those numbers, holding US Treasuries requires a meaningful premium to justify currency and duration exposure. That premium is not currently sufficient. The money is coming home.

That flow does not stop when Hormuz reopens. It is structural.

Five converging forced sellers are now identifiable. Oil inflation is repricing Federal Reserve cut expectations out of the curve — the first. Lifer repatriation, confirmed at ¥3.42 trillion per month, is the second. Three of the four major Gulf sovereign wealth funds are reported to be discussing withdrawal from US investments — a conditional third that was not in the original analysis. The MOF intervention chain becomes active if USD/JPY reaches 160, requiring liquidation of Treasury reserves to defend the yen — a fourth. War financing issuance builds with no congressional constraint after the House voted down the War Powers resolution — a fifth that grows with every week the conflict continues.

Against these five, Bessent has one active tool: accelerated Treasury buybacks. It is a stalling action. It does not add net demand.

The tools he lost

The Federal Reserve is the most important tool Bessent cannot use. Powell’s term expires May 15. Kevin Warsh remains structurally blocked in the Senate committee. From May 15 until confirmation, the Fed operates without a permanent chair. The reaction function becomes unknowable. If no 2026 Fed cuts get priced into the curve, the 10-year moves above 4.25% and the constraint breaks.

Congressional war constraint was the other tool. The House voted it down. There is no longer a political mechanism to force the conflict’s end on a financial timeline. Trump’s “weeks not months” framing was the market’s anchor. Congress removed it.

The self-contradiction

Bessent’s own 15% global tariff announcement this week adds cost-push inflation on top of energy inflation. Higher inflation expectations raise yields. His own policy is tightening his own binding constraint.

What Bessent is still doing

Two moves confirm the original framework is still operating.

On March 5, the Treasury issued a 30-day waiver allowing Indian refiners to continue purchasing Russian crude. The deliberately short window signals an expectation that the Hormuz situation resolves within a month. It is an attack on the transmission chain at its source: if oil falls, yen pressure eases, UST demand stabilises.

Accelerated buybacks continue. These are damage-control moves, not solutions. They are consistent with what the original piece described: a man managing plumbing under extreme constraint, buying time for the military timeline to deliver the economic outcome he needs.

The carry paradox

In a normal crisis, the yen strengthens and carry trades unwind. In this crisis, the yen has weakened — moving from 156 to 157.95 during active conflict with VIX above 25. Japan’s 72% dependence on Hormuz oil means higher crude generates dollar demand for energy imports that overwhelms safe-haven buying.

Carry traders holding short-yen positions feel safe at 157.95. Positions are not being trimmed. When MOF intervention arrives — likely at 160 — those positions will be caught fully loaded. The unwind will be more violent precisely because the initial yen weakness gave false comfort. The spring is loading, not releasing.

Aozora’s Moroga, Mizuho’s Karakama, SMBC’s Suzuki, and ANZ’s Machida have all independently flagged the yen’s oil-crisis vulnerability. The consensus among Japanese bank analysts is unusual enough to be worth noting.

What the perfect landing now requires

The scenario remains possible. Preserved oil infrastructure still signals an intent to deal. The India-Russia waiver still signals short expected duration. Buybacks still signal active yield management.

But the margin for error has compressed considerably since February 28. The first yield threshold is now behind us. Lifer repatriation is confirmed and structural. Gulf SWF risk is new and unpriced. The Fed chair vacancy removes the dovish pivot option. Congress has removed the political mechanism that would have enforced a short timeline.

At $89 oil, Brent is 24% above the level where Bessent’s arithmetic worked. The 30-year JGB auction this week recorded a bid-to-cover of 3.66 — solid demand, repatriation already visible in auction outcomes. That flow is bullish for Japan. It is not bullish for the asset class being sold to fund it.

The framework is intact. The conditions it required are deteriorating.
