The Fed's optimistic general and the shock it hopes will fade

INFLATION IS "unquestionably too high at about 4%". So said John Williams, president of the Federal Reserve Bank of New York, on July 15th. Yet Mr Williams added that there are "encouraging reasons" to believe it has peaked and should edge down in the coming quarters. He forecasts it falling to around 3¼% by year-end, then on a glide path to the Fed's 2% target by 2028.

The arithmetic of that forecast is impressive. The politics of its credibility are less so.

Mr Williams delivered his remarks at an event in Rockefeller Centre, a few days after the consumer price index (CPI) reported a stunning 0.4% monthly decline in June - the largest single-month fall since April 2020. The drop pulled the annual inflation rate down to 3.5%, well below the 3.8% forecast by many economists. It gave Mr Williams's case a timely data point. The trouble is that the data point was itself a hostage to events.

The June price decline was driven overwhelmingly by energy. A temporary ceasefire between the United States and Iran had sent oil prices down, and pump prices followed. Energy costs, which had risen 23.5% in May, slowed to 15.7% in June. That is the kind of one-off that looks like confirmation in one month and reversal in the next. Sure enough, hostilities resumed in mid-July, Brent crude climbed to $88 a barrel by July 17th, and shipping traffic through the Strait of Hormuz plummeted. Whether the latest flare-up will persist, or fizzle as the last one did, is impossible to say. Mr Williams's forecast assumes it will fizzle.

That assumption is the linchpin of his entire analysis. Mr Williams identifies three forces driving this year's inflation: tariffs on imported goods, energy shocks from the Middle East war, and the supply-demand squeeze caused by the artificial-intelligence investment boom. His optimism depends on all three receding. He says tariff impacts have "largely played out", with new duties merely replacing expiring ones rather than adding impulse. He says energy prices have "likely peaked" and will fall closer to pre-conflict levels. And he says the AI-driven imbalances in semiconductors, transformers and electricity demand will "recede over time as more supply comes online".

It is a tidy diagnosis. The question is whether the tidy diagnosis survives contact with a messier reality.

Take the tariffs. Mr Williams is right that the direct pass-through from existing tariffs has already been largely incorporated into prices. But that is not the same as saying tariffs have stopped distorting the economy. The politics of trade remain unsettled. Any escalation - whether from the United States, China or Europe - would introduce new price pressures that Mr Williams's "no significant additional impulse" framing would miss. The risk is not today's tariff schedule but tomorrow's.

Energy is the bigger problem. Mr Williams says oil prices will come down. He may be right. The Strait of Hormuz carries roughly one-fifth of the world's oil supplies, and its disruption is a classic transitory shock - precisely the kind of event central bankers have spent the past five years learning not to ignore. During the pandemic-era price surge, the Fed waited too long, letting inflation expectations de-anchor. Mr Williams's calm posture is in some sense a course correction: do not overreact to a supply spike; focus on whether it feeds into wages, prices and expectations. On that score he is probably right. The labour market is not adding to inflationary pressures. Medium-term inflation expectations in the New York Fed's own survey have stayed well anchored. Those are good signs.

But anchoring is not the same as immunity. If the energy shock drags on - if the Strait remains disrupted through autumn, or if the conflict broadens - the cost will not stay confined to the pump. It will flow through transport, manufacturing and food. And at that point the Fed will face a choice between standing firm in hopes of a resolution, or tightening to prevent second-round effects. Mr Williams's script assumes the first path. Other members of the Federal Open Market Committee are less certain.

The institutional tension is telling. At its July meeting, the Fed's new chairman, Kevin Warsh, left rates unchanged at 3.5% to 3.75%. The vote was 9 to 3, with three members - the presidents of the Cleveland, Dallas and Minneapolis Fed banks - favouring a quarter-point hike. The June dot plot showed a median year-end rate projection of 3.8%, a sharp upward revision from the 3.4% pencilled in at the March meeting. That divergence signals a committee that is watching the same data but drawing different conclusions about what to do next.

Mr Warsh's own communication has done little to resolve the ambiguity. His prepared remarks after the July meeting were hawkish: "Where necessary and appropriate, we will not hesitate to act." In the press conference that followed, he offered vaguer answers that investors read as dovish, sending long-term Treasury yields higher and the dollar lower. That kind of muddle is a luxury no central bank can afford when inflation is running at twice its target and the oil market is behaving like a geopolitical lottery.

Mr Williams's optimism matters precisely because he is a permanent voting member of the FOMC, the New York Fed president carrying the most weight among regional bank chiefs. His steady tone is meant to anchor expectations. If the shocks prove stickier than he assumes, his calm public posture risks lending credibility to a price path that the committee will eventually have to fight against. In that case, the dovish general could become the most constraining.

The second-order consequence is what markets will make of it. Rate futures are now pricing in a hike by September. Some investors, stung by Mr Warsh's incoherent press performance, are positioning for nothing. Either way, the Fed is navigating between two failures: tightening prematurely in response to a transitory spike, or standing still while a supply shock becomes embedded. The right answer depends on which side of that line the next three months of data fall on.

The danger is not immediate collapse. It is slower: weaker investment, higher costs and a politics of permanent subsidy. The first task for the Fed is to keep its reading of the data honest. If Mr Williams's three-shocks theory holds, patience is the right policy. If the shocks compound - tariffs interacting with energy, energy feeding into wages, expectations starting to drift - the committee will need to act before a dovish narrative takes on a life of its own.

For now, the bets are split. The question is who gets to call the resolution.
