In our Letter this week, we examine the ongoing Iran war through an Asian lens. Geopolitical uncertainty and crude oil prices have remained elevated (chart 1), despite early reports concerning the potential for a brief conflict that tempered investor caution. Attention has now centred on the Strait of Hormuz, through which a significant share of global oil typically flows. With shipments now nearly halted (chart 2), much of the world’s energy flow has effectively stalled. While these developments have broad global implications, their impact on Asian economies is more nuanced. This partly reflects differences in energy mixes across the region (chart 3), as well as the historical relationship between oil prices and energy inflation (chart 4). Further compounding the challenges faced by Asian oil importers are currency effects: a broader risk-off turn in markets has weighed on several Asian currencies (chart 5), raising the local-currency cost of energy imports. Amid these pressures, several regional central banks are also set to decide on policy this week (chart 6), alongside major Western counterparts such as the Federal Reserve. Near-term rate cut expectations have been pushed back in many cases amid renewed inflation concerns, while in some Asian economies markets are even pricing in the possibility of further rate hikes.
The Iran war Two weeks in, the Iran war continues with no clear end in sight. Crude oil prices and geopolitical risk therefore remain elevated, as shown in chart 1, despite earlier news that had briefly tempered investors’ heightened caution. Even reports that the 32 members of the International Energy Agency are set to release around 400 million barrels in emergency reserves have done little to curb the surge in crude prices. Latest reports indicate that reserves for Asia will be released immediately, while supplies for Europe and the Americas will only become available from the end of March. Meanwhile, uncertainty surrounding the Strait of Hormuz continues to underpin elevated prices. The strait—currently blocked by Iran—handles roughly 20% of global oil flows. Iran has recently indicated that it may allow ships from certain countries to transit the waterway, though the situation remains fluid.
