Global Stock Market Selloff 2026: Stagflation Fears Return as Iran Conflict Reignites

The June 17, 2026 US-Iran ceasefire is officially over, and global equity markets from New York to Seoul to London are recalibrating for a second wave of geopolitical risk just as central banks were beginning to feel confident that inflation had peaked.

The Ceasefire Collapse and Immediate Market Reaction

U.S. forces struck more than 80 targets inside Iran over the July 12–13 weekend, and Iran’s Revolutionary Guard responded by moving to shut the Strait of Hormuz, ending a peace agreement that had briefly stabilized oil markets since mid-June, according to TheStreet. The S&P 500 fell 0.79%, the Nasdaq Composite dropped 1.55%, and South Korea’s Kospi has seen sharp single-session swings tied to chip-sector exposure, based on data compiled by CNBC.

Why Markets Fear Stagflation Rather Than a Simple Correction

What worries strategists is not the equity drawdown itself but the combination of higher energy costs and already-elevated inflation expectations. The Bank of England’s Monetary Policy Committee, in its June 2026 minutes, explicitly noted that global energy prices had fallen since the previous meeting only for tensions to reignite, warning that the impact of the “energy shock” on inflation “remains uncertain” even as it held its benchmark rate at 3.75% by a 7–2 vote, per the Bank of England. Two committee members had already voted for a hike before the latest escalation.

In the United States, the Federal Reserve under new Chair Kevin Warsh held rates at 3.50%–3.75% through its June meeting, with markets pricing a 97% probability of another hold, according to GoldSilver’s market analysis. But the reignition of the Iran conflict complicates the Fed’s next moves ahead of its July 29 decision, since renewed oil-driven inflation could force policymakers to abandon rate-cut plans entirely.

Regional Spillover: Canada, Pakistan, and Southeast Asia

Canada’s economy — already navigating a technical recession tied to unresolved CUSMA tariff negotiations — now faces a second drag from rising gasoline prices, even as energy exports partially offset the hit, according to BNN Bloomberg. Pakistan’s IMF-backed recovery program explicitly flagged the Middle East war as clouding its near-term outlook, since higher global commodity prices raise the risk of renewed inflation just as Islamabad works to rebuild foreign reserves, per the IMF’s staff report. Indonesia, a net energy importer, saw its rupiah slide further amid the broader dollar-strength trade tied to the conflict, according to Indonesia Investments.

What Investors Should Watch Next

The next major catalysts are the Fed’s July 29 rate decision and the Bank of England’s own meeting the same day, both of which will be forced to weigh renewed energy-driven inflation against already-fragile growth. Markets across all nine of the world’s major financial centers — from Wall Street to the Dubai Financial Market — are likely to remain volatile until there is clarity on whether the Hormuz blockade proves temporary or structural.
