US Intervenes to Boost Yen Amid Currency Market Volatility

The United States has intervened in Japan's currency market for the first time in over a decade to prop up the yen, which has hit a 40-year low against the dollar. President Donald Trump said the move was 'a signal of friendship' and would benefit both countries.

The intervention, which involved the US buying Japanese yen, was aimed at countering excessive volatility in the currency market. Japan's Finance Minister Satsuki Katayama said the action helped to counter disorderly movements in the yen in recent months.

Analysts believe that a stronger dollar makes American exports pricier for foreign consumers, while a weak yen benefits Japanese exporters but increases the cost of imports like oil and gas, fueling inflation. The US has interests in shoring up the yen to mitigate this effect.
