As the year 2025 unfolds, the central banks across Asia find themselves in a precarious position, navigating through the turbulent waters of economic challengesWith the US dollar continuing its upward trajectory, Asian currencies such as the Japanese yen, South Korean won, and Indian rupee have slipped to multi-year lows against the dollar, placing immense pressure on the region's economies.

Analysts are closely monitoring this trend, especially considering the backdrop of looming tariffs and trade tensions from the United StatesA weaker currency may typically enhance export competitiveness; however, it also brings with it risks of increased import-driven inflationThis delicate balancing act leaves central banks with a difficult choice: whether to intervene in the currency markets to support their domestic currencies or to adopt a more hands-off approachSuch decisions hinge on numerous factors, including the implications for inflation and speculative pressures on local currencies.

Since November 5, 2024, the dollar index has surged, reflecting a noteworthy appreciation of approximately 5.39%. Economists attribute this to several economic policies enacted in the US, notably tax reforms and tariffs, which are expected to contribute to inflationary pressures domestically

Minutes released from the Federal Reserve's December meeting suggest that officials are increasingly concerned about inflation's impact on policy, consequently opting to slow the pace of interest rate cuts amidst prevalent uncertainties.

This re-evaluation has widened the gap in yields between US and certain Asian bonds, diminishing the allure of lower-yielding assets and prompting intervention from several major central banks, including the Bank of Japan and the Reserve Bank of IndiaJames Oh, a market strategist at Tiger Brokers, commented on the situation during an interview with CNBC, suggesting that the strong dollar complicates the monetary policy landscape for Asian central banks, which must now navigate rising import costs that add pressure to domestic inflation.

Oh noted that attempts by central banks to bolster their currencies through interventions could potentially strain their foreign exchange reserves

For nations currently grappling with high inflation and currency depreciation, it may prove counterproductive to reduce interest rates in an effort to stimulate economic growth.

Among the hardest hit is Japan, which experienced its yen drop to a decades-low rate of 161.96 yen per dollar in July 2024. In response, the Bank of Japan intervened aggressively, spending over 15.32 trillion yen (approximately $970.6 billion) throughout 2024 to stabilize the currencyDespite these efforts, the yen continues to hover around 158 yen per dollar, marking a stark realization of the currency's struggles, paralleling Japan's long battle with inflation.

In stark contrast to its earlier deflationary years, Japan is now witnessing inflation rates exceeding the Bank of Japan's target of 2% for an impressive 32 consecutive monthsHowever, the central bank acknowledges that a weak yen may exacerbate rising import-related inflation, creating further challenges in maintaining price stability

The critical task for policymakers lies in ensuring that the momentum of rising prices and wages does not overwhelm the acceptable thresholds set by the central bank.

Turning to South Korea, the Korean Central Bank's recent interventions aimed at stemming the depreciation of the won have raised concerns as the currency dropped sharply against the dollarWhile the central bank refrained from disclosing specific intervention figures, the nation’s foreign reserves have dwindled to their lowest levels in five yearsSince November 5, the won has steadily lost value and reached around 1,476 won to the dollar in December, a level last seen in 2009.

In a less favorable position is India, whose rupee has faced relentless pressure due to the strengthening dollar and foreign portfolio investors' sell-off in October and NovemberBy January 8, the rupee sank to an unprecedented low of 85.86 rupees per dollar

India's inflation has also recently surpassed the Reserve Bank of India's 6% tolerance level, reaching 6.21% in OctoberWhile the rate has since tempered, the country continues grappling with inflationary challenges exemplified by a waning economic growth trajectory.

Latest figures reveal India's GDP growth dropped to 5.4% in the second quarter, marking its lowest point since the last quarter of 2022. At the December monetary policy meeting, the Reserve Bank found itself in a divided position, maintaining interest rates at 6.5% while two members advocated for a 25 basis points cutShould India decide to lower rates in a bid to invigorate economic activity, it poses significant risks of further rupee depreciation.

Citigroup's 2025 outlook report notes that India’s sizable foreign exchange reserves add a buffer for the rupee's stability amidst such uncertaintiesKen Peng, an analyst with Citigroup, even characterized the rupee as “one of the most stable currencies globally,” second only to pegged currencies like the Hong Kong dollar
