Macro & Markets Weekly — Mar 26, 2026

The Strait of Hormuz is now the world's most important financial instrument — and nobody can agree on its price. Oil whipsaws about 4% on the session with every ceasefire headline, the Fed is frozen while bond markets price a rate hike as of this week, Goldman Sachs just bumped recession odds to 30% this week, and the fertilizer shock quietly being written into Northern Hemisphere soil this week will show up in your grocery bill by Christmas. The one load-bearing wall left in the U.S. growth story — AI infrastructure spending — just got a concrete datapoint from Micron confirming demand is real, but that's a narrow pillar for a $28 trillion economy to lean on.

The U.S. transmitted a 15-point ceasefire plan to Iran through Pakistan. Iranian Foreign Minister Abbas Araghchi told state media the exchanges don't constitute "negotiations with the US," and Tehran laid out its own conditions — including a demand to collect transit fees from every ship passing through the Strait of Hormuz, modeled on Egypt's Suez Canal tolls. On Monday, March 23, five ships passed through the strait. On Tuesday, March 24, six. Some days since the war began on February 28, the count has been zero.

If a deal materializes, markets could see lower oil prices — but not back to pre-war levels. Saul Kavonic, head of energy research at MST Marquee, noted that even with a reopened strait, producers need time to restore shut-in production, shippers need confidence the ceasefire holds, and physical damage to Gulf infrastructure like Ras Laffan means LNG and oil flows face multi-month constraints regardless. If no deal comes — or if Trump's five-day military pause expires without extension — the $100+ Brent floor hardens and the energy tax on every household and business in the world persists into Q3.

The signal to watch: daily Hormuz transit counts. If they move from single digits to sustained double digits, de-escalation is physical, not just verbal.

The FOMC held rates at 3.5%–3.75% on March 18 — the third consecutive hold. The median dot plot still shows one 25-basis-point cut this year. But Powell told reporters there was "a meaningful amount of movement toward fewer cuts by people" — roughly four or five members shifted from two expected cuts to one. The statement added explicit language about "uncertainty about the implications of developments in the Middle East for the U.S. economy."

Markets heard something the Fed didn't say. Futures now price roughly one cut for all of 2026 — down from three at the start of the quarter, as of this week. Morgan Stanley flagged that bond market pricing has moved to a 40% probability of a Fed rate hike by October, as of this week. Meanwhile, TD Securities argues the Fed will "look through the energy shock" as long as longer-term inflation expectations stay anchored.

If the hike pricing proves right, every floating-rate borrower and every company planning a bond offering faces a fundamentally different cost of capital than they modeled in January. If TD is right and the Fed eventually cuts, the delay alone has already tightened financial conditions — mortgage rates popped back above 6.2% this week, killing a brief housing affordability window. Watch Core PCE on Friday and the April jobs report — those two prints will determine whether the hike narrative strengthens or breaks before the April 28–29 FOMC meeting.

Goldman Sachs raised its recession probability from 25% to 30% this week, cut its GDP estimate to 2.1%, and boosted its year-end PCE inflation forecast to 3.1% — all on the back of an oil shock that has pushed gas prices up $1.02 per gallon in a month, the biggest spike since Hurricane Katrina. JPMorgan sees 35% odds; Bank of America says risks are underpriced. Mark Zandi of Moody's Analytics told CNBC: "Recession is a real threat here," noting that an oil shock has preceded virtually every U.S. recession since the Great Depression except Covid.

The specific mechanism: tax refunds — boosted by recent tax legislation — were supposed to fuel spring consumer spending. Morgan Stanley now estimates refunds are tracking only 12% above last year, below their 15–25% forecast, and downgraded consumer spending growth to 1.7% from 2.0%. "The oil shock essentially washes out that bump," said Morgan Stanley's Arunima Sinha. Weekly credit-card data from JPMorgan and BofA still looks okay — but the pump spike is only three weeks old. March retail sales, released mid-April, will be the first clean read on whether the gas price surge has reached household behavior. If it misses consensus by more than half a point, every recession model on the Street gets updated the same day.

In a week where almost every growth forecast got cut, Micron's earnings offered the exception. Management described AI-driven DRAM and NAND demand as so strong they can only meet "50% to two-thirds" of mid-term requirements for key customers. HBM supply is essentially sold out, and the company guided revenue above Street expectations.

This matters beyond semiconductors because the U.S. growth story now explicitly depends on AI infrastructure capex as a load-bearing wall. Data centers are relatively insulated from imported energy costs thanks to cheap domestic natural gas, and the associated spending has been keeping the expansion alive alongside portfolio-driven consumption by top earners. But that's a narrow base. If any hyperscaler — Microsoft, Google, Amazon, Meta — guides down on AI infrastructure spending during late-April earnings, the impact won't be confined to tech multiples: expect downward revisions to growth forecasts, revenue guidance for chip and server suppliers, and a sizable hit to industrial capex suppliers. The observable signal: watch capex guidance language in those calls as carefully as you'd watch a jobs print.

FOB granular urea in Egypt — a bellwether for nitrogen fertilizers — is now around $700 per metric ton as of this week, up from $400–490 before the war. Oxford Economics' Alpine Macro puts urea and ammonia price increases at roughly 50% and 20% respectively since the conflict began, per CNBC. Persian Gulf countries account for nearly 49% of global urea exports and about 30% of ammonia exports, according to Alcott Global's supply chain analysis.

The timing is the cruelest part: Northern Hemisphere farmers are fertilizing fields right now. Early data suggests a significant acreage shift away from nitrogen-intensive corn toward legumes — a physical, irreversible decision being made this week. StoneX estimates food inflation will rise sharply with a 6-to-12-month lag, meaning Q3 and Q4 CPI prints are being written in the soil right now. For FMCG, food service, and retail CFOs, the planning window to hedge input costs is closing. The USDA's final acreage report will confirm or deny the corn-to-legume shift — that's the data event to calendar.

A March note from GMO's fixed-income team highlights how razor-thin compensation for risk had become going into the oil shock: U.S. high-yield spreads sat only modestly above 2021 tights, with almost no cushion. Over the past two weeks, broad high-yield option-adjusted spreads have widened by several tens of basis points, and the riskiest CCC-rated names — the part of credit nobody quotes on TV — have moved more.

We're not in a credit crunch. Issuance is still happening, and there's no forced deleveraging. But this is the mechanism by which macro shocks become corporate-finance problems six to twelve months later: funding costs for leveraged borrowers drift up just as growth turns mixed and oil spikes. Watch primary-market pricing on new bond deals and whether covenants start to tighten. That will tell you if investors are demanding a bit more yield or starting to ration credit altogether. The former is normal; the latter changes the refinancing math for every levered company with maturities in 2027.

Germany's Ifo Business Climate Index dropped sharply in March, but the real headline is the expectations component — one of its worst single-month falls in two decades. The Ifo Institute noted the Middle East war has put "any hope of a recovery" on ice. This kind of forward-looking collapse typically precedes cuts to capex and hiring across Europe's industrial core.

Combined with the Bank of England holding at 3.75% (with previously dovish member Dave Ramsden flipping to a hold on oil-driven second-round effects) and the Swiss National Bank's surprise cut to 1.5%, Europe is fracturing: some economies need easing, others can't afford it, and the resulting policy divergence is feeding dollar strength that tightens conditions globally. If Eurozone flash CPI on April 3 shows disinflation, ECB cut rhetoric accelerates and the euro weakens further — a currency headwind for every U.S. multinational with significant European revenue.

Six ships through the world's most important waterway. A 40% chance the Fed raises rates while officially planning to cut them. Farmers switching from corn to soybeans because nitrogen costs more than the crop is worth.

The last time Iran proposed collecting tolls on an international waterway, the idea was so absurd it didn't make the briefing — now it's a formal ceasefire demand and Goldman's recession model has an opinion about it.

Stay sharp out there.

If someone you know is trying to make sense of oil, rates, and the food chain simultaneously — forward this. They'll thank you.
