Recently, the Japanese yen has shown a strong upward trend against the US dollar, rising for four consecutive weeks, a rare occurrence considering the yen's continuous depreciation in recent years. The latest spending data released by the Japanese government further validated market expectations that the Bank of Japan might raise interest rates this year, driving the yen's exchange rate against the dollar higher. The rise in risk aversion in financial markets has also fueled global capital flows into safe-haven assets like the yen and gold, while the dollar has faced profit-taking sell-offs due to its high position and uncertainties in Trump's tariff policies.
After Trump announced a delay in imposing tariffs on Canada, the yen began to accelerate its rebound, showing a notable performance against the US dollar. Japan's latest economic data further supported market optimism, especially with wage growth reaching its highest increase in nearly thirty years, accelerating the yen's rise. Moreover, the remarks from hawkish officials at the Bank of Japan have reinforced market beliefs that the central bank might raise rates soon. Particularly, the policy interest rate of the Bank of Japan might double to 1% by March 2026, greatly driving the yen's continued appreciation.
Foreign exchange strategists generally believe that the Bank of Japan's monetary policy path will lean towards a hawkish stance, while other major central banks like the Federal Reserve and the European Central Bank might continue to implement loose policies. This policy difference gives the yen upward potential this year and is expected to significantly narrow the yield gap between Japanese government bonds and those of other major economies. On Friday, the yen-dollar exchange rate fell to 150.96, the lowest level since December. Although it retreated afterward, the yen's gain against the dollar this week has exceeded 2%, marking its largest rise since late November last year.
Another reason for the yen's strength is investors reducing their long positions on the dollar. With declining yields on US Treasury bonds across all maturities and Trump's decision to delay tariffs, the strong dollar reversed, further facilitating the yen's rise.
Despite the market's cautious attitude towards the outcome of Japanese Prime Minister Shigeru Ishiba's meeting with the US President, and the high vigilance regarding any comments on tariffs or yen weakness, the overall market trend still leans towards expecting a strong yen.
Robust economic data has further fueled market expectations for a Bank of Japan rate hike. Both household spending and wage growth in Japan have far exceeded expectations, reaching their biggest increases since August 2022, further boosting the yen's appreciation. The market now anticipates a significantly higher probability of a rate hike by the Bank of Japan in the coming months, with an 80% chance by July and even a 100% possibility by September.
Additionally, statements from hawkish Bank of Japan officials, such as former Governor Haruhiko Kuroda and former Executive Board Member Naoki Tamura, have strongly supported rate hike expectations. Naoki Tamura stated that the Bank of Japan will continue with the normalization of monetary policy, while Haruhiko Kuroda emphasized that Japan has "fully" emerged from deflation. As a result, market bets on a rate hike by the Bank of Japan are growing stronger, and the yen is expected to continue benefiting from this policy trend.
Overall, the robust rise of the yen against the US dollar is not coincidental. Changes in global economic and financial policies, along with Japan's economic recovery, have all strongly supported the yen’s appreciation. The market's increasing expectations for a Bank of Japan rate hike could potentially drive the yen further upward, making it an important indicator in the global foreign exchange market.
