MARKETS Market Brief

Global markets witnessed significant volatility over the past 48 hours, initially reacting negatively to hot inflation data and escalating geopolitical tensions before staging a strong rebound.

On June 10, 2026, market sentiment soured following the release of the U.S. Consumer Price Index (CPI) for May. The data revealed a 4.2% year-over-year increase, marking a three-year high. This surge was primarily attributed to spiking gas? prices, linked to the ongoing conflict in the Middle East. Compounding the negative outlook, President Trump's threats of further strikes on Iran led to a sharp downturn in U.S. equities. The S&P 500, Dow Jones Industrial Average, and Nasdaq composite all closed significantly lower on this day. Scott Anderson, chief U.S. economist at BMO Capital Markets, warned on June 10, 2026, that without a moderation in energy prices, "it will only be a matter of time before we see more visible spillovers into other goods and services categories and into inflation expectations."

A clear catalyst for a dramatic shift in market sentiment emerged on June 11, 2026, when U.S. stocks rallied sharply. This turnaround was primarily fueled by hopes for a de-escalation in the U.S.-Iran conflict. Reports indicated that President Trump had reportedly called off threats to bomb Iran, suggesting a potential deal to restore the global flow of oil. This news immediately sent oil prices tumbling and boosted investor confidence across major indices. AI-related stocks, which had seen a sell-off on June 10, 2026, also rebounded on June 11, 2026.

In a cross-asset context, the European Central Bank (ECB) also made a significant move on June 11, 2026, raising its key interest rates by 25 basis points. This marked the first hike since 2023, with the ECB explicitly citing inflation pressures stemming from the Middle East war as the reason. Meanwhile, U.S. Producer Price Index (PPI) data, also released on June 11, 2026, showed a higher-than-expected headline figure, though the core PPI (excluding food and energy) was milder, offering some relief on underlying inflation concerns.
