As traders bet that global monetary policy will shift from interest rate cuts to hikes, the Australian dollar, the Norwegian krone, and the New Zealand dollar have significantly outperformed other major currencies this year. Year-to-date, the Australian dollar has surged more than 6% against the U.S. dollar, reaching its highest level in nearly three years. Earlier this month, the Reserve Bank of Australia raised its benchmark interest rate by 25 basis points to 3.85%, marking the first rate hike by the central bank in over two years. The RBA explained that inflation in the country is expected to remain above the target range of 2% to 3% for some time. Many analysts believe this marks the beginning of a sustained tightening cycle, with traders speculating on one or two additional 25-basis-point rate hikes this year. Meanwhile, the New Zealand dollar has gained approximately 3.7% against the U.S. dollar year-to-date, as markets anticipate the country's first interest rate hike in the coming months. The Norwegian krone has risen more than 5%, driven by unexpectedly high inflation that has led traders to price in the possibility of a modest rate increase in the first half of the year. These three currencies have emerged as the top performers among the G10 currencies. Investors suggest that this trend reflects a significant shift in the interest rate cycle—major economies are gradually moving away from the rate-cutting policies of recent years and refocusing on curbing inflation. Mansoor Mohi-uddin, Chief Economist at Bank of Singapore, commented that these countries are like "canaries in the coal mine," signaling a broader shift toward "hawkish" policy. Higher relative interest rates tend to drive exchange rate appreciation in advance. Due to the significant weight of commodities in the economic structures of Australia, New Zealand, and Norway, these currencies are often categorized as "commodity currencies." Strategists note that recent increases in oil, copper, and other export commodity prices have also provided support for these currencies. Oliver Levingston, a foreign exchange strategist at Merrill Lynch, pointed out that with Australian interest rates exceeding those in the United States for the first time since 2017, combined with gradually rising commodity prices and a weaker U.S. dollar, the Australian dollar may gain "more tailwinds." Analysts also noted that concerns over policy volatility under the Trump administration and rising U.S. government debt are prompting investors to diversify away from U.S. dollar assets, further benefiting the three commodity currencies. Currently, the support provided by relatively higher U.S. interest rates is gradually diminishing. Under strong pressure from Trump, most traders believe the Federal Reserve's rate-cutting cycle is not yet over and expect two to three additional 25-basis-point cuts this year. However, some argue that the Fed's easing cycle may end sooner than anticipated, with J.P. Morgan and BNP Paribas forecasting no rate changes this year. Some Fed officials have indicated in meeting minutes that "the possibility of renewed rate hikes should not be ruled out." Additionally, as markets worry about widening government deficits and soaring debt, investors are favoring countries with relatively sound public finances, which has further boosted the Australian dollar, Norwegian krone, and New Zealand dollar, while weighing on the Japanese yen, U.S. dollar, and British pound.
