Asian stocks rebound on US-Iran peace hopes after Middle East tensions hit regional currencies

Asian currencies tumbled sharply on Monday amid surging Middle East tensions, with the South Korean won posting the steepest losses as fears mounted over a potential collapse in the fragile US-Iran ceasefire. The US dollar surged to a one-week high during the session, bolstered by the escalating standoff between Washington and Tehran, while Gulf stock markets declined in early trading on similar concerns. According to reports from Asharq Al-Awsat, these moves reflected investor anxiety over disruptions in the Strait of Hormuz, a critical chokepoint for global oil shipments carrying 20-25% of the world's supply.

European stocks also slid on Monday as hopes for de-escalation in the region flickered and then faded, with geopolitical risks resurfacing. Gold prices dropped amid a stronger dollar and fresh inflation worries tied to Hormuz-related shipping snarls, as refiners scrambled for alternative crude supplies and paid record premiums for oil from the US Gulf Coast and North Sea. One notable incident involved a US destroyer halting two oil tankers from leaving Iran, underscoring the physical fragmentation of energy flows despite diplomatic signals.

By Tuesday, market sentiment shifted dramatically toward optimism. Asian stocks rebounded strongly, fueled by news of potential peace negotiations between the US and Iran, possibly resuming in Islamabad or over the weekend following President Donald Trump's comments that a deal feels "very close." Oil prices extended their retreat, with Brent crude dipping to around $94.63 a barrel and West Texas Intermediate falling to $90.58, as traders unwound the "war premium" baked into earlier surges—prices had jumped about 50% in March before this pullback. The dollar eased back, putting pressure on the Japanese yen, while investors pivoted to risk-linked assets.

This volatility highlights the markets' extreme sensitivity to US-Iran headlines, as noted by analysts like UBS's Giovanni Staunovo. A temporary reopening of the Strait of Hormuz has already spurred stock gains and oil declines, though Trump warned the blockade could snap back without a full agreement. Refiners face ongoing challenges, with US sanctions waivers on Iranian and Russian oil quietly expiring, tightening supply further.

The stakes extend beyond trading floors. Export-dependent Asian economies, including South Korea, stand to suffer from a stronger dollar and pricier imports if tensions persist, while Gulf nations grapple with stock slumps amid their oil reliance. Farmers worldwide could see higher costs from shipping disruptions rippling into agricultural production. Eyes now turn to upcoming US inventory data and any official word on talks, which could either stabilize prices or reignite the risk-off spiral.

For global consumers, sustained Hormuz issues risk pushing energy costs higher, fueling inflation and slowing growth—though de-escalation signals offer a lifeline. As negotiations hang in the balance, with Iran reportedly floating nuclear freeze proposals, markets remain on edge, poised for the next headline to dictate the direction.
