January 2024 brought a notable shift in global currency markets, led by a stronger Japanese yen that posted its best January performance since 2018. The yen rose about 1.6% over the month, even after some weakness toward the end of January.
Investor expectations of further Bank of Japan (BOJ) rate hikes underpinned the yen’s advance. Tokyo’s core inflation reached 2.5%, bolstering the case for tighter policy, and comments from BOJ officials reinforced the view that additional tightening is possible. Those factors helped lift the yen against a range of currencies.
In North America, currencies faced mounting uncertainty as markets focused on a politically driven deadline: U.S. President Donald Trump’s planned February 1 decision on imposing 25% tariffs on imports from Mexico and Canada. That prospect weighed on the Canadian dollar and the Mexican peso. The Canadian dollar fell to five-year lows, while the peso suffered its worst weekly drop since October, reflecting heightened trade-risk concerns and investor caution.
Elsewhere, the European Central Bank’s policy moves contrasted with those of the BOJ. The ECB has signaled a willingness to ease policy further, cutting rates and leaving room for additional easing steps, whereas the Federal Reserve has remained more measured, indicating caution on the timing and pace of any rate reductions. These divergent policy stances added to the mixed signals driving currency flows.
The U.S. dollar index remained relatively firm in the run-up to the tariff deadline, but it was on track for a small monthly decline of about 0.3%. That modest loss reflected the complex interaction of monetary policy expectations, inflation trends, and geopolitical trade risks that shaped investor positioning across currencies in January.
Overall, January’s market moves highlighted how central bank guidance and political developments can quickly shift currency dynamics. The yen’s gains underscore the market’s responsiveness to rising inflation and the prospect of policy tightening in Japan, while North American currencies illustrated how trade-related political risk can drive volatility and weaken local units.
