The markets do not tolerate uncertainty, and neither, it seems, does the United States Congress. In a rare display of bipartisan spine, the House of Representatives has voted to limit President Trump's ability to wage war against Iran. The resolution, which now heads to the Senate, is a direct rebuke to a President who has treated the war powers like a blank cheque.
For those of us watching from the Square Mile, this is not merely a political squabble. It is a signal that the fiscal and geopolitical risks of unilateral action are being priced in. The resolution passed 224-194, with every Democrat and a handful of Republicans voting to restrain the executive.
The trigger? The January 3rd drone strike that killed General Qasem Soleimani, a move that spooked global markets and sent oil prices spiking. The House is essentially saying: 'You do not get to drag us into another Middle Eastern quagmire without a vote.
' And rightly so. The cost of such adventures is not just measured in blood but in treasury yields and capital flight. The US national debt is already north of $23 trillion.
Another war would blow a hole in the fiscal accounts, pushing up borrowing costs and crowding out private investment. The bond market has been flashing warning signs for months. The yield curve inverted last year, a classic recession signal.
And now, the President's approval ratings are wobbling. This is not the time for cowboy diplomacy. The resolution's path through the Senate is uncertain.
Majority Leader Mitch McConnell has expressed opposition, but a handful of Republican senators, including Rand Paul and Mike Lee, have signalled support. If it passes, it would be a stinging defeat for Trump, and a clear message that the era of unchecked executive power is over. For investors, the takeaway is this: The political risk premium on US assets is rising.
The dollar may weaken, gold may rally, and gilt yields may become more attractive by comparison. The bottom line: Fiscal responsibility and market stability require checks and balances. The House has just reminded the world that not all of Washington is willing to bet the house on a roll of the dice.
