Economic Tsunami Watch
The relief rally that began on March 31 is in its fourth week. Twenty trading days in, the S&P 500 has recovered to within 2% of its all-time high. Most relief rallies of this kind run twenty to forty trading days before they break or extend.
This one is maturing. Earnings momentum has carried multiples up faster than earnings revisions can support. Forward P/E has expanded from 19.7 at the end of Q1 to 20.9 today. The catalyst that started the rally, the April 8 US-Iran ceasefire announcement, has unwound twice in the past nine days. The rally absorbed both.
What happens next runs through one specific event: the Trump-Xi summit in Beijing on May 14. Six paths lead through that window. Each carries different damage to the global economy, ranging from $2.4 trillion (2.2% of global GDP) in the best case to $6.9 trillion or more (6.3%+) in the worst.
The consequence matrix
| Branch | GDP damage | Oil price | Equity reaction | Vol regime | Credit spreads |
|---|---|---|---|---|---|
| A · 35% Partial deal |
(3.3%) global GDP | Brent eases to $80-85, premium persists | Rally extends on announcement, gives ground as Q2 transmission hits | VIX compresses to 15-17, rebuilds to 20-23 by July | IG widens modestly, HY widens on energy-exposed names |
| B · 25% Postponed |
(4.4%)+ global GDP | Brent stays $100-115, war premium intact | Rally breaks within days of announcement, 5-8% leg down | VIX spikes to 25-30, stays elevated | IG widens 30-50bp, HY widens 100-200bp |
| C · 15% Full reopening |
(2.2%) global GDP | Brent normalizes to $70-75 by Q3 | Rally extends to new highs, second leg up on Q3 normalization | VIX compresses to 14-16 | Spreads tighten meaningfully across credit |
| D · 10% Drift through |
(~2.7%) global GDP | Brent choppy in $90-105 range | Range-bound through summit, resolves on summit outcome | VIX 20-25, wide intraday ranges | Modest widening, wait-and-see |
| E · 10% Accidental escalation |
(3.6-4.5%) global GDP | Brent spikes to $120+ on incident | Sharp break on event, magnitude depends on severity | VIX spikes to 30+, recovery variable | Sharp widening on incident, slow recovery |
| F · 5% Escalation |
(6.3%)+ global GDP | Brent $140-180+, sustained elevation | Crash dynamic, 10-15%+ leg down, deeper if broadens | VIX 35-45+, genuine crisis | HY blows out 300bp+, IG widens 80-100bp+, market dysfunction risk |
The deadline that decides the rally
Trump’s Beijing visit on May 14-15 is a target deadline. The administration tied the war’s resolution to the summit when it rescheduled the trip in March after originally postponing. We believe Trump needs a Hormuz resolution he can claim as victory before he arrives in Beijing. Without one, Xi presents the peace framework, which Trump must publicly accept or publicly reject. Both options are bad for the narrative he has been building. With a resolution, Trump arrives with the win, the summit produces the trade headlines, and markets can better understand the economic damage to that point.
Pakistan is the mediator, and that detail matters. Oman has been the historical Iran-US back-channel since the Carter administration: the Iran-Contra negotiations, the JCPOA’s earliest groundwork, the 2023 prisoner swap. Oman is pragmatist-coded diplomatic infrastructure. Pakistan, on the other hand, is a Sunni Muslim country that gives Iranian hardliners domestic cover. The choice of Pakistan over Oman tells us that Iran’s hardliners are running their side of the channel, not the pragmatists who would normally manage de-escalation.
Here is why we perceive an asymmetric clock. The US is on the fastest clock because Trump’s prestige concerns become political-survival concerns within weeks if economic transmission accelerates. Gas prices above $5 sustained or unemployment above 5% would compress the timeline further. Iran is on the slowest clock because regime survival is currently stable and Persian negotiating culture treats endurance as proof of moral standing. Iran knows the US clock is the binding constraint. Iran is running it out.
We see the April 17 reopening, the April 18 reimposition, and the April 23 mine-clearing escalation as tests of US pain tolerance, calibrated to find the line at which Trump capitulates rather than escalates. Despite these events, the market closed up on April 24.
Why even the best case carries damage
We estimate the wave of cumulative GDP destruction is a function of closure duration. Every day the strait stays effectively closed adds more damage. Insurance war-risk premiums, tanker rerouting around the Cape of Good Hope, refinery margin compression, and the second-order economic damage from elevated rates all run on physical timelines that are already landing in Asia and parts of Europe.
Even Branch C in the chart, full Hormuz reopening, the genuine best case, runs cumulative damage to roughly $2.4 trillion (2.2% of global GDP) before normalization arrives. Shipping companies need verified safe-passage data. Insurance underwriters need to see months of clean transit before lifting war-risk premiums. Tanker capacity has to be repositioned from Cape routes. The Ras Laffan LNG facility took its first damage on March 2 and repairs will likely take years. A diplomatic agreement during the May 1-11 window does not reverse any of that.
The transmission to corporate earnings is already visible. United Airlines withdrew its 2026 financial guidance on April 13, citing $100+ oil and the company’s policy of not hedging fuel prices. Delta has flagged a projected $2 billion increase in quarterly operating costs. Two companies in the same sector with the same exposure confirm what we already expect: lower economic growth no matter what. The rally is likely to burn itself out before that pattern fully emerges, but the sector-by-sector damage that surfaces through Q2 operational updates, guidance revisions, and pre-announcements is what turns a rally exhaustion into a market correction or worse.
What to watch in the next ten trading days
Three signals will likely resolve the open question.
How the actors line up
Closing read
The rally is already mature and at record levels. It can stall, give back, or break at any time in the coming weeks. What happens to the broader market after that depends on which branch resolves.
Three clocks are running. The rally’s own exhaustion is the shortest, measured in days to weeks. Hopefully, a diplomatic resolution arrives by May 14, eight to thirteen trading days from now. The wave damage arrives over thirty to sixty days as Q2 oil-cost transmission shows up in operational updates, guidance revisions, and pre-announcements.
A favorable diplomatic outcome leaves the market elevated against forward earnings that have not yet been revised to reflect the damage, with the next leg dependent on what those Q2 updates actually show. The wave then drives a market move whose severity scales with which branch resolved: a dip in the favorable cases, a correction in the base case, a crash in the tail outcomes. An unfavorable diplomatic outcome breaks the market sooner and from the same elevated starting point.
Resolution is not the same as recovery.
