Emerging Asian currencies took a hit on Thursday as a combination of rising oil prices and higher US Treasury yields kept the dollar near a two-month high. The MSCI emerging market currency gauge fell 0.4%, its biggest one-day drop since mid-May, with several regional currencies weakening against the greenback.
Indonesia's rupiah was the hardest hit, sliding as much as 0.6% to 17,900 per US dollar—its weakest level since early August. The Thai baht, Philippine peso, and Indian rupee also lost ground, each falling between 0.1% and 0.3%.
Why oil and yields matter for emerging markets
For many economies in Asia, the combination of higher crude prices and rising US bond yields is a double whammy. Most of these countries are net importers of energy, so when oil climbs, their import bills swell, putting pressure on trade balances and currencies. At the same time, higher US Treasury yields make American assets more attractive to global investors, often pulling money out of riskier emerging markets and into dollar-denominated investments.
This dynamic is especially pronounced when the Federal Reserve signals that interest rates will stay higher for longer. As US yields rise, the dollar tends to strengthen, and currencies in developing economies—which often carry more risk—tend to weaken.
The recent move in yields has been notable. US 10-year Treasury yields have climbed to levels not seen in years, driven by strong economic data and concerns about government debt issuance. As yields hit multi-decade highs, the pressure on emerging market assets has intensified.
Oil's role in the selloff
Oil prices have also been on the rise, with Brent crude recently topping $100 a barrel. For Asian economies that rely heavily on imported oil, this adds to inflationary pressures and widens current account deficits. The Indian rupee, for example, is particularly sensitive to oil prices because India imports about 80% of its crude needs. As oil climbs, the rupee often comes under pressure, and the central bank may step in to support it.
Indeed, the rupee has been under pressure as oil tops $100 and US yields surge, with the Reserve Bank of India seen as likely to intervene to smooth volatility. Similarly, Bank Indonesia has been active in supporting the rupiah, recently holding interest rates steady while bolstering its currency defenses.
What this means for investors
For everyday investors, the slide in emerging Asian currencies is a reminder of how interconnected global markets are. When US yields rise, it can ripple across the world, affecting everything from the value of your international investments to the price of imported goods.
If you hold investments in emerging market funds or stocks, a weaker local currency can eat into your returns when converted back to dollars. On the flip side, a stronger dollar can benefit US-based investors with foreign assets, but it can also make US exports less competitive.
For those with exposure to Asian markets, it's worth watching how central banks respond. Some, like Bank Indonesia, have already signaled they will defend their currencies. Others may be forced to raise interest rates to stem capital outflows, which could slow economic growth.
The broader backdrop is also important. Rising bond yields have implications for portfolios, from bond prices to equity valuations. Higher yields make borrowing more expensive, which can weigh on corporate profits and consumer spending.
Looking ahead
Investors will be watching for any signs that the dollar's strength is easing, or that oil prices are stabilizing. Key data releases, such as US inflation reports and jobs numbers, will also be in focus, as they could influence the Federal Reserve's next moves.
For now, the pressure on emerging Asian currencies appears to be part of a broader trend. As the Australian and New Zealand dollars have also slid against the greenback, it's clear that the dollar's strength is a global phenomenon.
For the average investor, the takeaway is to stay diversified and be aware of currency risk. While emerging markets offer growth potential, they also come with volatility, especially when global conditions shift. As always, it's wise to focus on long-term goals rather than short-term market moves.
