Why the World Is Watching the Yen

Summary

The Japanese yen has weakened to multi-decade lows against the dollar, pressuring Japan's cost of living and prompting political incentives to strengthen the currency. The US is concerned that a weak yen forces Japan to sell US Treasuries, pushing up American borrowing costs, so Treasury Secretary Scott Bessent has intervened in the yen and warned investors not to bet against him. The video explains the BOJ's low-rate policy, the global yen carry trade, and the difficult trade-off Japan faces in raising rates without harming fragile growth.
