Yen Stuck in Intervention Zone as BOJ Bets Build
The Japanese yen has been hovering at around 159 per dollar for several days, prompting concerns about potential intervention by the Bank of Japan. The currency is currently in an intervention zone, where Tokyo's currency warriors typically step in to stabilize it.
Despite the Bank of Japan's efforts to prop up the yen, the 10-year US Treasury still yields close to 4.7 percent against under 2.9 percent on the 10-year Japanese government bond. This gap keeps the carry trade alive, where investors borrow cheap yen to hold higher-yielding dollars.
Mitsuhiro Furusawa, Japan's former top currency diplomat, expects the Bank of Japan to raise rates in September and believes it should do so, citing a faster pace of hikes as crucial for communication. The Bank of Japan has already lifted its rate to 1 percent in June, the highest setting since the 1990s.
The yen's fate now rests with the Federal Reserve's path and the pace at which the Bank of Japan normalizes interest rates. Further yen appreciation will likely require more Bank of Japan hikes, according to Fitch Ratings. Meanwhile, Bank of America strategists see the yen jumping to 149 per dollar by end-2026 if the market's hawkish repricing holds.
The yen's value has implications for countries that have borrowed in yen, such as Kenya, which has a Nippon Export and Investment Insurance-backed samurai facility of up to JPY 25 billion. A weaker yen trims the shilling cost of servicing that debt, but a sudden Bank of Japan-driven rally would push it back up.
