US House Passes Resolution to Limit Trump's War Powers on Iran

Key Facts

In a move reflecting heightened tensions between legislative and executive branches over foreign policy, the US House of Representatives voted to restrict President Trump's ability to wage military operations against Iran. According to reports, the House passed the resolution with a 215-208 majority, directing the President to withdraw U.S. forces from the Iran conflict. The measure invokes the 1973 War Powers Act, requiring an end to hostilities within 30 days unless Congress issues a formal declaration of war.

This legislative push, framed against 'Operation Epic Fury,' comes at a sensitive time for global markets monitoring energy supply stability in the Middle East. Historically, such resolutions often face a presidential veto, limiting their immediate impact on field operations. However, the political friction could weigh on investor sentiment in the defense and energy sectors, especially as markets await Fed Chair Powell’s speech scheduled for May 31, 2026, per economic calendar data.

Traders should watch for an official response from the White House, as the resolution is widely expected to be vetoed or ignored, likely keeping geopolitical risks on the table. Economically, the market is looking forward to the US ISM Manufacturing PMI release on June 1, 2026, which will provide a clearer signal on US economic resilience amid these tensions. Oil and gold prices remain the most sensitive instruments to any escalation or softening in rhetoric between Washington and Tehran in the coming days.
