Asian Currencies Under Iran-Driven Strain as Rupee Nears Lows

Asian currencies face a critical test after Iran-war signals rattled markets, while the Indian rupee (USD/INR) nears its all-time low. Most Asian FX pairs stayed in tight ranges on Thursday—treating the risk as “tense stability”—but vulnerabilities remain as traders watch for energy-price volatility and potential escalation. The US dollar held near three-month highs, supported by safe-haven demand, firm Fed policy expectations (delayed rate cuts per futures), and geopolitical risk premiums. This dollar strength can worsen conditions for emerging markets with USD-denominated debt; IMF data cited in the article puts emerging Asia’s dollar debt exposure at ~35% of total external obligations. Japan’s yen traded in a ~0.3% band versus the dollar, while the Chinese yuan showed limited movement after PBoC intervention. Analysts attribute the relative calm to prior risk pricing, high FX reserves for defense, and reduced Middle East energy import dependence. The key stress point is the Indian rupee, trading within ~0.15% of its record low around 83.45 per USD. Drivers include elevated crude oil costs (India imports ~85% of petroleum), foreign portfolio outflows (about $1.2B in selling during the month), and concerns over a widening trade deficit. The RBI is reported to have used roughly $3.5B in FX reserves this month to smooth volatility, with further intervention expected if the rupee tests historical support. Options positioning also signals caution: one-month risk reversals widened for several pairs, and the rupee’s risk reversal hit the highest level since September, indicating increased protection demand against further depreciation.
