The chair's first Jackson Hole address names the two conditions the desk registered as its risk branch: inflation progress he cannot call meaningfully improved, financial conditions he is hard pressed to call restrictive. The front end reprices September from roughly a third to a coin flip. The thirty-year moves one and a half basis points. Five tests were published before the events; the desk scores them here, the miss first.

On Friday morning the new Fed chair gives his first Jackson Hole address, and at the same hour the statisticians publish the preliminary payrolls benchmark revision, an exercise whose previous preliminary estimate subtracted 911,000 jobs. Between now and then: the Fed's preferred inflation gauge, a Bank of Korea decision that could deliver the global tightening cycle's newest hike, and a Treasury reported, twice in one Monday session, to be willing to do whatever it takes to defend its own long end. Three hands now reach for the same pen: a committee that declines to write, a market that has been writing all month, and an issuer that wants to steady the hand. The desk's practice before weeks like this is to publish its tests first and score them after. Here are the tests.

Forty-eight hours after minutes showed his committee arguing for higher rates, Kevin Warsh named the people who will redesign the Federal Reserve: five outside task forces led by former central bankers, leading academics and technologists, with recommendations due by year-end. The easing bias is not just fading from the votes. It is being written out of the institution. The rebuild begins. The floor hardens.

The shorthand: the long end holds its band while the Fed and the ECB turn hawkish in the same week and the pipeline stays firm beneath them, and only the Bank of Japan still holds. The floor under long rates is no longer a US idiosyncrasy. It is a synchronised, cross-central-bank regime, and the yen is where the one holdout's divergence is being paid.

The shorthand: forward guidance was a term-premium suppressant, and the new chair is removing it. The 30-year sits near 4.94%, the front end anchored near 4.21%, the curve steep at +70bp, and the 10-year breakeven still near 2.21%. Firm long yields with flat breakevens is a premium story, not an inflation one. The floor under long rates does not fall when the Fed goes quiet. It gains a new leg. Same floor, higher premium.

The Iran ceasefire is signed and Brent has fallen into the high 70s, yet the 30-year has not followed it down. The financial press is now asking why. The desk answered it before the question was asked: the floor under the long end was never the war. It is the bid, and this week the bid got thinner while the deficit got heavier.

The shorthand: a credible ceasefire framework arrived and the 30-year held 4.97%, higher on the week, not lower. The Bank of Japan lifted its policy rate to 1.00%, a 31-year high, and cut its bond buying. Credit compressed (HY OAS 2.71) rather than widened, so this is not a fear trade. USD/JPY barely moved at 160, so the carry unwind is a slow burn, not yet a shock. The war premium leaving could not lift the long end off the floor, because the floor is the vanishing buyer, not the conflict. Warsh meets that floor tomorrow.

On Wednesday, Kevin Warsh chairs his first FOMC with headline inflation at its fastest since 2023 and a hot producer pipeline already on the board. On Friday, the US and Iran are set to sign in Geneva. The market is asking what the new Chair will do. The desk's answer: he inherits a Fed that cannot cut and will not hike at its debut, and the thing actually moving the long end is not in Washington. It is in Switzerland.

On the same day, the US pipeline ran hot beyond energy and the ECB hiked for the first time since 2023, justifying it on a broadening of price rises. The euro was sold on the hike. The 30-year held its third test in a week. Inflation is spreading past the oil story on both sides of the Atlantic, and the dollar is the relative winner.
