A critical legal and economic inflection point is approaching as the Trump administration nears a May 1 deadline to seek congressional authorization for ongoing military operations in Iran.
According to Saxo Bank analysts, "US President [Donald Trump] has a May 1 deadline for seeking congressional authorization for the war in Iran under the War Powers Resolution of 1973, which states that if no formal declaration of war or other authorization has been made, he must wind down any military action within 60 days."
The countdown, triggered by the law, is beginning to rattle global energy markets already strained by the effective closure of the Strait of Hormuz.
Under the 1973 law, a US president can only extend activity beyond the 60-day mark under specific, narrow conditions.
An federal government document clarifies the high bar for such an extension noting, "Such sixty-day period shall be extended for not more than an additional thirty days if the President determines and certifies to the Congress in writing that unavoidable military necessity respecting the safety of United States Armed Forces requires the continued use of such armed forces in the course of bringing about a prompt removal of such forces."
Despite the escalating conflict, Congress has not issued a formal declaration, yet. The US Senate website notes that "Congress approved its last formal declaration of war during World War II."
For energy markets, the May 1 deadline is a source of price volatility. Brent crude has already seen surges of up to 57% since the conflict began on Feb. 28.
With roughly 20% of global oil supply passing through the Strait of Hormuz, the threat of a legal vacuum where the US military must theoretically withdraw without a stable ceasefire risks a second shock to prices.
Analysts warn that if the administration ignores the deadline or fails to secure authorization, the resulting gray zone of legality could lead to unpredictable naval engagements.
This uncertainty keeps a persistent premium on oil as traders weigh the possibility of a prompt removal of forces against an unpredictable environment where both sides have not yet agreed when the next round of peace talks will take place.
However, modern conflicts rarely resemble the declared wars of the 1940s. Congress holds the power to declare war, but has since agreed to several resolutions for use of military in different conflicts without formal declaration of war.
They unfold through airstrikes and intelligence cooperation, actions that allow administrations to sidestep the War Powers Resolution by arguing involvement does not rise to the level of hostilities.
The Iran resolution denies this flexibility as the Trump administration did not get Congress authorization prior to the conflict. It likely will reassert the premise that "Congress has the sole power to declare war under Article 1, Section 8, Clause 11 of the United States Constitution."
For the energy sector, the answer will determine whether oil prices stabilize or enter a new round of wartime volatility.
