TL;DR
The Fed decision arrived today, September 16, with markets pricing a near-certain 25bp hike — the first since July 2023 — while the bond rout worsened underneath it: the 10-year hit 5.04%, the highest since 2007. The driver is a diesel shock that keeps compounding, with retail diesel at a record $6.27/gallon and consumer sentiment at the second-lowest reading since 1952. This extends last cycle's picture of a Fed cornered by energy inflation, but the escalation is now running through refined products and infrastructure, not just shipping lanes.
The diesel shock is no longer an oil story — it's a refinery and infrastructure story
The supply shock behind the Fed's hawkish turn escalated on multiple fronts this week, with Brent at $108.06/barrel on Tuesday — a four-month high after a 9% weekly gain. Unlike the initial Hormuz disruption, the damage now runs through physical infrastructure:
"Ukraine has destroyed almost 40 percent of Russia's refining capacity via drone attacks as far away as the 460,000-barrels-per-day Omsk refinery in Siberia… This has forced the Kremlin to ban diesel exports from a country that once accounted for 11 percent of global seaborne diesel trades." — Diesel shock threatens a new era of global stagflation — AGBI
Saudi Arabia's East-West pipeline has shut down after Houthi strikes, Gulf states halted Hormuz talks, and Beijing cut fuel export quotas. The Trump administration has rejected fuel-export restrictions and pledged "all-time high" domestic production — no demand-side lever is being pulled ahead of November. AGBI's framing of a potential "first 'stagflation decade' since the 1970s" matters because it explains why policymakers are out of tools: neither the Fed chair nor the Treasury secretary "can print molecules or calories."
What to watch: whether the Saudi pipeline shutdown and Russian refining losses translate into further diesel crack-spike pressure into October, or whether diplomatic off-ramps reopen.
Households are absorbing the shock in real time — and saying so
The consumer squeeze intensified past last week's milestones. Diesel crossed $6.00/gallon nationally on September 11 and the AAA average hit a record $6.27/gallon by Tuesday — roughly $3.70 a year earlier — while the diesel crack spread spiked to $106/barrel against a normal $25–30 range. The August CPI shows fuel oil up 52% year-over-year, and AGBI flags that roughly 75% of US food costs run through diesel-based fertilizer, tractor, and delivery costs, meaning grocery inflation is still in the pipeline.
Sentiment has collapsed accordingly:

The University of Michigan's September reading of 47.8 is the second-lowest on record back to 1952, with one-year inflation expectations surging to 4.6%. That's the political economy backdrop to today's FOMC decision — the bottom of the "K-shaped" economy is squeezed by a supply shock a funds-rate hike "barely touches," while paying more for debt service on top of it.
What to watch: August retail sales data (due today, with consensus around a +0.8–0.9% rebound from July's -0.6%) as the first hard read on whether consumers are still spending through the diesel shock.
The Fed hikes into a contested room — and the hold case isn't dead
Markets converged on a 25bp hike to 3.75%–4.00% today, with CME FedWatch at 92.7% and hike pricing rocketing from roughly 33% a month ago. The Reuters poll erased the last doubt:
"An 85% majority of economists, 86 of 101, in the Reuters survey conducted after Friday's inflation report said the Fed would raise rates by a quarter percentage point to 3.75%-4.00% at its September 15-16 meeting, the first increase since July 2023." — Fed meeting live updates — Yahoo Finance
But the dissent is unusually loud for a near-unanimous market consensus: Mark Zandi calls a hike "a mistake" outright because the inflation is supply-shock fallout that "rate hikes can't fix," Loretta Mester says market probabilities exceed her own, and Adam Posen argues the Fed shouldn't decide "based on one last-minute piece of data." Morgan Stanley expects a second 25bp hike in December, and a majority of Reuters respondents see at least one more by March 2027. The political dimension is live: NEC Director Kevin Hassett pledged the White House will "100 percent support" Warsh regardless, even as Macquarie notes that if Warsh dissented against his own committee, he'd be the first modern Fed chair to do so.
What to watch: the dot plot for how many further 2026–27 hikes officials project, then the BEA's September 30 PCE methodology revision, which could reframe the inflation picture a fortnight later.
The bond market called Bessent's bluff — and won
The 10-year Treasury yield reached 5.04% on Tuesday, its highest since 2007, with the 30-year touching 5.39% — a decisive burying of the Treasury buyback intervention that last cycle's digest flagged as strained. The 2-year surged to 4.60% against a 3.50% overnight rate, pricing in the hike plus follow-through. AGBI's Matein Khalid is unsparing:
"Bessent boasted that he was 'the house' and dared the Street's bond vigilantes to bet against him. So, they did exactly that and won, while Bessent lost his credibility in this high-stakes game of global financial chicken." — Diesel shock threatens a new era of global stagflation — AGBI
The long-term cost of capital has risen roughly 103bp since the shock began, keeping mortgage rates above 7%. Yet equities are wobbling, not panicking — the S&P 500 closed at 7,585.73, only about 3% below its August 13 record, with AI-driven dip-buying limiting the damage even as bitcoin slid below $76,000.
What to watch: whether heavy federal debt issuance keeps driving yields higher despite the buyback program, especially if the Fed signals a December follow-up hike.
What surprised us
- The equity market's stoicism. A first hike in three years, a 5% 10-year, and a record diesel price — and the S&P is 3% off its all-time high, with Reuters noting "no sign of panic" as AI dip-buyers absorb the rotation. The bond and stock markets are telling completely different stories about the same macro picture.
- How fast the hike consensus formed. Pricing went from ~33% to 94.5% in a single month, driven by one CPI print, one payrolls report, and Brent crossing $100. Warsh's refusal to give forward guidance means every meeting is now a live data fight.
- The hold case has credible defenders. Zandi, Posen, Mester, and reportedly Williams and Waller all push back on hiking into a supply shock — meaning today's decision may be less a consensus than a committee majority dragging a reluctant chair along, with real distributional costs (a hike "extracts most of its cost from people who aren't the source of the inflation problem").
Open threads worth a vote
- Monthly US Retail Sales Release (August data due Sept 16) — the first hard consumer read under the diesel shock.
- FOMC decisions after September 2026 — next meeting late October; track whether the December second-hike call holds under Warsh's no-guidance regime.
