Today's Thesis

Oil's war premium is back. Markets price stagflation as ceasefire hopes evaporate.

Stocks fell 1.7% to 2.4% across the board on Thursday as oil prices rose and doubt replaced hope about a near-term end to the Iran war. The Nasdaq fell into correction territory, marking the worst day since the conflict began. The causal chain is simple: markets had priced a ceasefire that now looks less certain, and energy costs are rising faster than central banks can tolerate without hiking rates again—the exact stagflation scenario that kills both growth and equity valuations.

Iran War Escalation Uncertainty and Oil-Driven Inflation Expectations

CEASEFIRE UNCERTAINTY
Hopes for a near-term Iran war resolution collapsed, repricing the oil-shock scenario markets had begun to dismiss.
For the past two days, markets had rallied on the assumption that a ceasefire was imminent or highly probable. That assumption reversed Thursday. The conflict remains active, oil prices rose on the session, and central banks face the exact problem they cannot solve cleanly: sustained energy inflation without a clear off-ramp. This is not minor news—it resets the entire risk calculus for the next 6-12 months.
This unwinds until either (1) a genuine ceasefire is announced with credible enforcement, or (2) oil retreats on demand destruction. Neither is likely in the next 30 days. Expect volatility to remain elevated and directional downside bias to persist until oil stabilizes.
INFLATION EXPECTATIONS SHIFT
The OECD updated global inflation forecasts higher based on sustained energy prices, forcing policymakers into an impossible position.
The OECD's fresh inflation guidance confirms what markets have known for weeks: oil shock + duration = stagflation. Australia, UK, and others are already cutting growth forecasts and warning of rate hikes despite slowing economies. This is signal, not noise—central banks are now openly acknowledging they cannot accommodate both inflation and growth simultaneously.
Watch for RBA and other non-US central banks to hike rates in April-May despite negative growth revisions. That will accelerate the bear case and confirm stagflation is real, not theoretical.

Oil is rationing growth and forcing central banks to choose between currencies and equity valuations.

Think of it this way: when gas prices spike at your local pump, you have two choices—drive less or spend less on everything else. Neither is good for the economy. Right now, global central banks face the same constraint. Higher oil prices push inflation above acceptable levels, which forces rate hikes, which kills growth and earnings, which crashes equities. The classic stagflation trap. What makes this instance harder than 2022-23 is that markets already knew oil was a problem then—they were braced. This week, they were not. The repricing is sharper because the surprise was bigger.

Oil shocks that last 6+ months kill equity returns, but the damage depends on whether central banks can ease before earnings collapse.

2022
Russia-Ukraine war sent oil to $130. Markets fell 20% in the first three months, bottomed in June at -22%, but recovered to +9% for the year as inflation plateaued and the Fed paused. Lesson: the recovery started when oil fell, not when the war ended.
The market doesn't care about geopolitics—it cares about what oil does to margins and inflation.
1990-91
Iraq invaded Kuwait, oil spiked to $40 (then unthinkable), markets fell 20% in three months. But the war was fast—six weeks—and oil fell immediately after. Recovery was V-shaped: markets rebounded 60% in the next 18 months as inflation collapsed.
A short, resolved war is survivable. A long one with sustained oil elevation is not.
1973-74
OPEC embargo lasted months, oil tripled, inflation hit 12%. Markets fell 45%. Recovery took years because central banks had to break inflation with aggressive hikes that created a decade of stagnation.
When oil shock meets policy uncertainty, equities stay depressed until policy clarity emerges and inflation turns.
Directional Read

The primary variable is oil price stability. If oil holds $90-100 and the market assumes it stays there, you see a grinding bear case over 8-12 weeks as growth revisions cascade. If oil spikes above $120, you get capitulation and faster repricing downward. If oil falls below $80 on ceasefire news or demand destruction, you get a relief rally. The key: none of these outcomes are currently priced. Watch Brent crude Friday morning for the signal.

Scenario A — Ceasefire + Oil Collapse: Credible ceasefire announced with enforcement mechanisms + Brent falls below $80 within 48 hours = S&P 500 rallies 8-12% as stagflation fears evaporate and Fed signals rate pause.
Scenario B — Escalation + Rates Higher: Conflict deepens + oil sustains $110+ for 90 days + RBA/BoE hike April/May despite growth cuts = S&P 500 breaks 6,200 on multiple compression as stagflation becomes consensus.
