Why Japan is propping up the yen with US help

In a coordinated joint effort, the United States and Japan recently intervened in currency markets to support the value of the yen. This intervention came after a series of steep declines in the currency's value, which has been a growing concern for both nations. The US and Japan warned that they would not hesitate to take further action to defend the yen's value if necessary.

The weakening yen has become an issue for Japan's policymakers, driving up import prices and household living costs. It has also raised concerns for the US, given Japan's heavy reliance on imported energy, particularly oil from the Middle East. This has made Japan highly exposed to disruptions in the region, which in turn has put pressure on the yen.

Several factors are contributing to the yen's weakness. The gap between Japan's ultra-low interest rates and those in the US and other major economies has encouraged investors to borrow cheaply in yen and invest in higher-yielding assets overseas. This has led to capital outflows and persistent pressure on the Japanese currency.

Investor concerns about Japan's fiscal outlook, including its heavy debt burden and persistent budget deficits, have also eroded confidence in Japanese assets and the yen. Additionally, the Middle East conflict has increased global inflation, shifting expectations around US interest rates from cut to hike. This has made dollar-denominated assets even more attractive, further undermining the yen.

The yen's decline over the past decade has transformed Japan into an affordable travel destination for millions of foreign tourists and boosted the profits of the nation's biggest exporters. However, it has also driven up costs for households and squeezed the profitability of domestically focused businesses, contributing to inflation and economic challenges. The weak yen has become a significant issue for Japan, with domestic inflation becoming more entrenched.
