Commentary: Currency dynamics beyond a commodity shock

Risk aversion around the March/April war in the Middle East has led to the broad dollar index strengthening by about 2% over the January/February period, reversing the preceding 12 months’ depreciation trend. But the development is hardly a general one.

Against G-10 currencies, except for the Japanese yen, the USD has depreciated substantially since the beginning of Donald Trump’s presidency last year. The trend turned mixed during March/April, with the likes of the Kiwi Dollar and Swiss Franc weakening a tad, and oil rich Norwegian Krona sustaining its appreciation trend against the USD.

The narrative is far more differentiated in Asia. Since the beginning of 2025, the region has essentially split up into three groups.

Group 1: The ascendant exporters

The AI wave has lifted the entire electronics ecosystem, with the exporters of China, Malaysia, and Singapore reporting record demand despite all the uncertainties with trade wars. The resulting bump in trade surpluses and the strong outlook for investments in electronics lifted these currencies. They have shown not much weakness since March either.

Thai baht’s outperformance story rests more on surging gold exports than electronics demand. That also explains why it has sold off lately, following the correction of gold price in the last couple of months. 

Group 2: The ones under US pull

Japan, South Korea, and Taiwan are also exports stalwarts, but they faced a great deal of pressure from the US last year, while lacking the heft of China to push back. Pledges were made by their governments to move some of their supply chain to the US, to invest hundreds of billions of dollars there, and to be subject to monitoring that such commitments are being honoured. Torn between dynamic exports and challenges from the US, the currencies of these economics have been largely flat.

Group 3: The three under pressure

Indian rupee, Indonesian rupiah, and the Philippines peso have had idiosyncratic drivers of underperformance. While the latest bout of selloff may be attributable to exposure to potentially soaring energy import bills, there are other reasons too. A late cycle capital market dynamic (India), fiscal and governance concerns (Indonesia), and tech and political disruption (Philippines) have played their parts as well, in varying degrees.      

With commodity prices and geopolitical turbulence likely to remain high, these currencies may well continue to behave as per their groupings in this analysis.
