Asian Currencies Rise as Dollar Weakens on Softer US Inflation Data, BOJ Rate Hike Speculation Fuels Yen Surge
Asian currencies broadly strengthened against the US dollar on Thursday, buoyed by softer-than-expected US inflation data that fueled hopes for a less aggressive Federal Reserve. The Japanese yen led the gains, surging to a near one-month high on mounting speculation of an imminent interest rate hike by the Bank of Japan (BOJ). This positive sentiment rippled through the region, although gains were somewhat tempered by anticipation of further key economic data releases later in the week.
The US Consumer Price Index (CPI) data released on Wednesday showed a slight moderation in inflation, providing some relief to investors who had been bracing for more aggressive rate hikes by the Federal Reserve. This softer reading spurred a sell-off in the dollar, benefiting Asian currencies which had been under pressure due to the strong greenback. While the dollar index remained above the 109 level, the slight retreat provided breathing room for Asian currencies to recover some lost ground.
The Japanese yen, in particular, enjoyed a significant boost, reaching its highest level against the dollar in nearly a month. This surge was driven by intensifying speculation that the BOJ, under Governor Kazuo Ueda, is preparing to shift away from its ultra-loose monetary policy. Recent comments by Governor Ueda, along with reports from prominent media outlets, suggest a growing likelihood of a rate hike as early as the BOJ’s next meeting. This prospect propelled the yen, which, like many of its Asian counterparts, had been weighed down by the prospect of higher-for-longer US interest rates throughout 2025.
The South Korean won saw more muted movement, holding steady despite the Bank of Korea (BOK) unexpectedly maintaining its benchmark interest rate. The decision to hold rates came as a surprise, given widespread expectations of a cut. However, BOK Governor Rhee Chang-yong indicated that further easing remains a possibility in the coming months, particularly as the South Korean economy continues to grapple with weak growth. The BOK’s decision was likely influenced by ongoing political uncertainty following the recent impeachment and arrest of President Yung Suk Yeol, which had previously triggered sharp market declines and pushed the won to a 15-year low.
Elsewhere in the region, the Chinese yuan edged lower against the dollar as investors awaited the release of crucial fourth-quarter economic data. The Australian dollar, meanwhile, bucked the broader trend, weakening slightly despite stronger-than-forecast labor market data. The robust jobs report reduced the likelihood of near-term interest rate cuts by the Reserve Bank of Australia, potentially putting downward pressure on the currency. The Singapore dollar remained largely unchanged, while the Indian rupee hovered near record highs against the dollar.
Overall, the Asian currency landscape was marked by cautious optimism as the dollar’s retreat provided some respite. However, the underlying dynamics of higher US interest rates and lingering global economic uncertainties continue to pose challenges for the region’s currencies. The market’s focus remains firmly on upcoming economic data releases, including China’s fourth-quarter figures, which could significantly impact currency movements in the near term. The potential for a BOJ rate hike also adds another layer of complexity, with its impact reverberating throughout the Asian currency market. Continued volatility is expected as investors grapple with these competing forces.
