This financial retreat comes as the South Korean won hit its weakest level since 2009, reflecting deep regional anxiety over the stability of global trade routes.
The primary driver of the panic is a late-night social media post from President Donald Trump, who gave Iranian leaders a 48-hour ultimatum to unconditionally reopen the Strait of Hormuz.
The President warned that the U.S military is prepared to “hit and obliterate” Iranian power plants, “starting with the biggest one first,” if shipping is not restored by Monday night.
The Strait of Hormuz is the world’s most vital energy artery, carrying approximately 20% of the global daily oil and gas supply, and its current state of effective closure has removed millions of barrels from the market.
Tehran has responded with its own set of dire warnings, with Parliament Speaker Mohammad Bagher Ghalibaf pledging that the waterway will remain “completely closed” if U.S threats are carried out.
He further threatened to irreversibly destroy regional infrastructure, a move that would likely keep oil prices at record highs for years.
As the 23:44 GMT deadline approaches, the IEA has officially labeled the situation a “major threat” to the world economy, noting that no nation will be immune to the secondary effects of the crisis, which include a severe choking off of global fertilizer and food shipments.
In addition to the energy shock, the spike in oil prices is expected to send global inflation soaring, prompting central banks to reconsider aggressive interest rate hikes.
The Reserve Bank of Australia has already moved to increase rates, and other major economies are expected to follow suit to brace for a sustained period of high borrowing costs.
As the clock ticks toward the Monday night deadline, the focus remains on whether the “Donroe Doctrine” will transition from rhetoric to a kinetic military campaign that could redefine the global economic order.
