Japan's yen defence
Where things stand
The yen has erased the gains from the US Treasury's intervention, with carry traders rebuilding short positions and concern growing over Japan's spending. Senator Warren is pressing Bessent to justify the operation, Bloomberg reports.
Japan's currency policy and its interest rates sit in different hands: the government intervenes in the foreign exchange market, the Bank of Japan sets rates. A weak yen raises import costs at home and sustains the carry trade, in which investors borrow cheaply in yen to buy higher-yielding assets abroad.
