The dollar climbed to a seven-week high on Thursday, following a hawkish interest rate decision from the Federal Reserve. The move put immediate pressure on several Asian currencies, with Malaysia's ringgit, Indonesia's rupiah, and South Korea's won all sliding to multi-week lows. Yet, in a notable divergence, stock markets in South Korea and Taiwan pushed higher, driven by renewed optimism around artificial intelligence-related earnings.
Why the dollar is strengthening
The Fed's decision to raise rates—and its signal that more hikes could be on the way—has made dollar-denominated assets more attractive. Higher US interest rates typically lift US bond yields, which draw global capital into the US. For investors in emerging markets, that means a stronger dollar and a weaker local currency, as they demand a higher return to compensate for the added risk of holding assets in countries with less stable currencies.
This dynamic played out quickly in Asia. The ringgit and rupiah slipped to multi-week lows, while the won touched 1,384.40 per dollar, its weakest level in three weeks. The moves reflect a familiar pattern: when the Fed tightens, capital tends to flow out of emerging markets and back into the US, putting downward pressure on local currencies.
Stocks hold up on AI earnings hopes
Despite the currency weakness, equity markets in the region showed resilience. South Korea's KOSPI rose as much as 1.2%, and Taiwan's TAIEX also gained, as investors focused on the potential for strong earnings from companies tied to artificial intelligence. Both markets are home to major semiconductor and tech firms that stand to benefit from the AI boom, and expectations of robust results have helped offset the drag from a stronger dollar.
This split between currencies and stocks is not unusual. While a stronger dollar can hurt exporters by making their goods more expensive abroad, it can also signal global demand for risk assets. In this case, the AI narrative appears to be powerful enough to keep equity investors engaged, even as currency traders position for further dollar strength.
What it means for investors
For everyday investors, the key takeaway is that a hawkish Fed can have different effects on different asset classes. Currencies in emerging Asia are likely to remain under pressure if the dollar stays strong, which could affect the returns of international funds and anyone holding foreign cash. On the other hand, equity markets in tech-heavy regions like South Korea and Taiwan may continue to find support from AI-related earnings, as seen in the recent AI-driven gains in chip stocks.
Investors should also watch how other central banks respond. The Fed's hawkish stance has already had ripple effects, with Latin American markets slipping and the Indian rupee sliding toward 96 per dollar. These moves highlight the global reach of US monetary policy.
For those with exposure to emerging market assets, the coming weeks could bring more volatility. Currency weakness can erode returns for foreign investors, but it can also make local stocks cheaper in dollar terms, potentially creating opportunities for those willing to take on the risk.
Looking ahead
The immediate focus will be on whether the dollar's strength persists and whether Asian central banks step in to support their currencies. In the past, policymakers have sometimes intervened to smooth excessive volatility, but such moves are often temporary. Meanwhile, earnings season in Asia will be closely watched, with AI-related companies likely to be the main drivers of market sentiment.
As the Fed's rate hike and hawkish signal continue to reverberate, investors should brace for a period of adjustment. The divergence between currencies and stocks may narrow or widen, depending on how global growth and corporate earnings evolve. For now, the AI trade appears to be holding up, but the currency pressure is a reminder that the Fed's actions still carry significant weight in emerging markets.
