Asian Currencies Weaken as Concerns Over Oil Prices Intensify

Oil Prices Soar Above $120 a Barrel, Weakening Asia's Most Vulnerable Currencies

The recent surge in oil prices above $120 a barrel is having a devastating impact on Asia's currency markets, pushing several of the region's most vulnerable currencies to all-time lows as inflation fears resurface. Since the war began two months ago, the Indonesian rupiah, Indian rupee, and Philippine peso have all experienced significant declines, making them among the weakest performers not just regionally but also across emerging markets.

The Indonesian rupiah and Indian rupee slid more than 0.5% against the dollar on Thursday to reach new lows, while the peso briefly approached that level. This selloff reflects the three nations' heavy reliance on imported oil, which has left their currencies highly exposed to the energy supply shock. Higher fuel costs threaten to rekindle inflation, hurt current and fiscal deficits, and complicate central banks' efforts to keep the economy afloat while containing prices.

The situation is particularly dire for the rupiah and peso, which are considered the most vulnerable currencies in the region. Ashwin Binwani, founder of Alpha Binwani Capital and a three-decade markets veteran, notes that the risks from the stalled ceasefire, a "dual blockade" on the Strait of Hormuz, and surging inflation mean Asian currencies are far from out of danger. A ceasefire collapse could trigger a recessionary spiral, further exacerbating the currency weakness.

Reversal of Fortune

Just a few weeks ago, an announced extended ceasefire between the US and Iran had convinced traders that the worst of the conflict was behind them. Investors had started to move back into risk assets, easing off the sell trade as energy prices eased. However, this optimism is now quickly being reassessed, with oil prices surging to near four-year highs and reports that President Donald Trump was soon going to receive a briefing on new plans for potential military action in Iran.

The derivatives market is pricing in a significant probability of further currency weakness. Currency options traders are pricing in around a 33% chance that the rupiah weakens to 18,000 per dollar over the next three months. Options also imply an 18% probability that the peso weakens to 65 and the rupee slides to 100 per dollar over the same period.

Central Banks' Efforts

Central banks in the region are taking steps to contain the fallout. The Reserve Bank of India has rolled out a series of measures, including opening a dedicated dollar-swap window for oil refiners and barring banks from offering the most widely used offshore rupee trading instrument, to curb speculation and support the currency. Indonesia's central bank has vowed to keep intensifying both offshore and onshore intervention, while the Philippine central bank has signaled that it's willing to deliver a series of modest interest-rate increases to rein in inflation.

However, analysts caution that these efforts appear to be limited without clearer signs that progress on the war's end is improving. The pressure is also spilling beyond emerging markets, with participants in Japan expecting officials to step into the market to offer support for the yen as it slides beyond 160 per dollar, its weakest level this year.
