What Happened This Week
The Fifth Consecutive Losing Week—and a New Coalition Forms
Operation Epic Fury is now four weeks old. Over 3,000 vessels remain immobilized across the Middle East—still the largest disruption to global shipping since World War II. U.S. Central Command reports more than 9,000 targets struck inside Iran.
The week was defined by two competing narratives: a high-profile U.S. diplomatic overture that Iran flatly rejected, and continued escalation that left little room for optimism. Israel launched a 48-hour surge in strikes on Iran's missile and nuclear infrastructure. On March 26, Israeli forces killed Iranian navy commander Alireza Tangsiri—the man directly responsible for ordering the closure of the Strait of Hormuz.
Iran turned away three container ships on Friday and blocked two Chinese vessels that had previously been granted passage. Trump extended his deadline to April 6. Iran's foreign minister said the country "does not plan on any negotiations." A coalition of 30 countries led by the UK and France has begun organizing a coordinated effort to reopen the Strait without waiting for U.S. leadership.

"Markets usually price in geopolitical events quickly and move on. This one is not resolving. Each week the Strait remains closed adds another layer of inflationary pressure, another notch of consumer confidence erosion, and another point of earnings risk."

Why It Matters
The Strait of Hormuz: 21 Miles, One-Fifth of the World's Oil
Twenty-one miles wide at its narrowest point. One-fifth of the world's daily oil supply. No real alternative route. In 2024, about 20 million barrels of oil and petroleum products moved through it every day—roughly 20% of global consumption and more than a quarter of all seaborne oil trade.
By March 11, daily vessel crossings had collapsed from 35–40 transits to just two—a greater than 95% drop. Iran is now charging ships approximately $2 million per vessel for passage through what markets have begun calling the Tehran Toll Booth. On March 27, that system showed signs of fracturing when Iran blocked two Chinese vessels that had previously been granted preferred passage—triggering Friday's oil spike.

Economic Pressure
How $100 Oil Moves Through the Economy
At roughly 49–55% above pre-conflict levels, the pressure from elevated oil prices is no longer theoretical—it's showing up in the data. Transportation and logistics costs continue to rise, hitting retailers, manufacturers, and food supply chains with input cost pressure that accumulates weekly.
The Federal Reserve faces a stagflationary dilemma: inflation driven by an external supply shock, not domestic demand—making rate cuts politically difficult and rate hikes economically counterproductive. The Fed held rates at 3.50%–3.75% in March and projected only one rate cut in 2026.

Historical Context
1973 and the Strait: What That Crisis Can—and Can't—Tell Us
In October 1973, Arab OPEC members cut off oil exports to the U.S. in retaliation for supporting Israel in the Yom Kippur War. Oil prices went from $2.90 a barrel to $11.65 by January 1974. The U.S. economy shrank approximately 2.5% and entered a severe recession through 1975. Equity markets didn't fully recover in real terms for nearly a decade.
Why a repeat is unlikely: The U.S. now produces approximately 13.7 million barrels per day—a complete reversal from 1973. North America accounts for roughly 30% of global oil output. The IEA has committed to releasing 400 million barrels collectively—the largest coordinated reserve release in history.
What hasn't changed: The GCC states produce about 22% of global oil and hold most of the world's spare production capacity—effectively offline right now. Japan and South Korea get more than 80% of their oil from the Middle East. China's Gulf dependency runs 40–45%. A prolonged shutdown slows Asian manufacturing, which flows back into U.S. corporate earnings.

Forward Outlook
Three Ways This Could Go
Everything flows from one question: how long does the Strait stay effectively closed?
The UK/France 30-country coalition gains operational momentum, providing the escort corridor needed to compel tanker traffic to resume—even without a formal ceasefire. A credible coalition commitment triggers de-escalation, the Tehran Toll Booth collapses, and oil falls sharply—probably back toward $80–$85 as the risk premium unwinds. The S&P 500 recovers its correction losses. The gap between diplomatic talks and ships in the water remains the central uncertainty.
Shipping stays constrained. Goldman Sachs's base case: Brent averages $105 in March, $115 in April, then retreats toward $80 by year-end. We estimate another 4–6 weeks of significant disruption—placing a realistic resolution window in the range of late April to mid-May. Uncomfortable, but manageable within historical precedent if the conflict remains geographically contained.
The Strait stays effectively closed for months. Strategic reserves thin out in early to mid-April. Oil moves sustainably above $120. Inflation re-accelerates while the labor market deteriorates simultaneously. That is stagflation. This is a fat-tail risk, not a base case—but the probability estimates below suggest the tail is fatter than most investors currently assume.
12-Month Recession Probability — Major Forecasters
Fixed Income Signals
What the Bond Market Is Telling Us
Investment grade corporate spreads remain roughly stable—the investment-grade bond market continues to treat the disruption as transitory. High yield spreads have actually tightened slightly; the ICE BofA US High Yield Index OAS stands at approximately 3.21%—well below the 5–6% range that signals real default risk. The credit market is not forecasting a wave of corporate defaults.
But the more revealing signal is in Treasuries. The 10-year yield surged to 4.44% on March 27—up 39 basis points since the conflict began on March 2. That move is being driven by the market pricing in higher inflation for longer, not by any improvement in growth expectations.
Stocks down and yields up simultaneously. That is the bond market's way of saying it is pricing in stagflation—an environment where inflation is too high to allow the Fed to cut, and growth is too weak to justify current valuations.

Key Indicators & Events
What We're Watching
Primary Indicators
Hormuz tanker traffic — primary indicator. Only 6 vessels transited openly on March 24; 3 turned away and 2 Chinese ships blocked on March 27
30-country UK/France coalition — most significant new geopolitical development; organizing vs. deploying is the critical gap to watch
WTI above $119.48 — breaking the March 9 intraday peak would signal material escalation beyond the current range
April 6 Trump deadline — another extension signals stalemate; a credible ultimatum backed by action would be a different signal entirely
Credit spreads — HY OAS at 3.21%; the 5–6% range signals real default risk and systemic stress
Mid-April SPR buffer expiration — Rystad's "buffer to fragile" warning; the window when the strategic cushion runs thin
Key Economic Events — Week of March 30
Apr 1 — ISM Manufacturing PMI (prior: 52.4; sub-50 signals contraction)
Apr 2 — Trade Balance: first full month of elevated oil import costs; January deficit was $54.5B
Apr 3 — Nonfarm Payrolls (consensus: 45k–50k; February was -92,000 — a second consecutive negative print would materially elevate recession probability)
Apr 6 — Trump's extended Hormuz deadline
Apr 9 — PCE Inflation data (most watched inflation print of 2026)
Our Message to You
Oil near $100 WTI and $112.57 Brent. Gas at $3.978 a gallon, up $1 in a single month. The Dow in correction. The Nasdaq in correction. The S&P 500 on pace for its worst month since 2022. Consumer sentiment at 53.3. The Iranian navy commander who ordered the Strait closed—killed this week. A 30-country coalition organizing to reopen the Strait—but only after a ceasefire. A U.S. peace plan—rejected. A new deadline of April 6.
There is more noise in this environment than there is signal, which is exactly when discipline matters most.
Here is what the evidence still says: credit markets are not panicking. High yield spreads are actually tighter this week. Corporate default risk, as priced in the bond market, remains contained. The 30-country coalition represents a genuine new development—the kind of coordinated allied response that, when it becomes operational rather than organizational, has historically been the inflection point that ends Strait disruptions.
The risk to that base case is that mid-April arrives and the buffer runs out before any of these diplomatic or coalition threads resolves. That is the window we are watching most closely.
