The Japanese yen has halted its decline just shy of a four-decade low, yielding an unexpected outcome: it has become the top-performing G10 currency against the U.S. dollar so far this month.
While the yen has depreciated by 1.6% against the dollar, the euro has fallen 2.5%, the Australian dollar has dropped 3.9%, and the Norwegian krone has declined over 6%. Despite the yen remaining at historically weak levels, traders are reluctant to bet on further depreciation due to concerns about potential Japanese intervention around the 161.95 level. A breach of this threshold would push the yen to its weakest point since December 1986.
Concurrently, a strengthening U.S. dollar, coupled with a more hawkish stance from the Federal Reserve, is exerting pressure on other currencies. Oil prices have also retreated to pre-war levels, driven by market optimism over the potential for a lasting agreement to end the conflict involving Iran.
"The yen's outperformance over the past month or so may not be solely due to fears of currency intervention," stated Jumpei Tanaka, Deputy General Manager of the FX Spot Trading Department at Mizuho Bank. He noted that falling oil prices and the gradual improvement in real interest rates from Bank of Japan rate hikes mean that "the factors that previously drove yen weakness are not as significant as before."
