Global risk appetite faded as optimism for a swift Middle East peace deal evaporated, driving investors toward safe-haven assets. According to reports, Iran’s negotiating team halted message exchanges with the U.S. in protest against recent attacks on Lebanon. This sudden suspension of diplomatic channels triggered a rise in oil prices amid escalating fears that continued military exchanges could disrupt navigation through the strategic Strait of Hormuz.

This geopolitical escalation comes at a sensitive time for markets monitoring energy supply stability, with Brent crude prices rising due to the potential risk of vital waterway closures, per market data. Compared to previous periods of tension, analysts suggest that the return of a geopolitical risk premium could pressure aviation and manufacturing stocks, while energy companies benefit from higher spot prices. Recent economic data, such as Italy's Business Confidence at 87.9 on May 28, 2026, reflects a cautious stance within the Eurozone regarding external shocks.

Traders are currently watching support levels for oil and gold to gauge the depth of the shift toward hedging. On the economic front, focus remains on Eurozone inflation data and U.S. JOLTS job openings to assess the broader economic outlook. The upcoming calendar features key catalysts, including a speech by Fed's Kashkari on May 29, 2026, which may provide insights into how central banks are weighing geopolitical risks against persistent inflationary pressures.
