The article says Japan spent ¥27.1 trillion defending the yen this year, but argues the intervention was funded mainly by running down bills and other assets rather than selling long-term US Treasuries. It says Japan’s intervention has not materially affected long-dated Treasury prices, which remain more influenced by Federal Reserve policy and Treasury supply.
The reported yen defense may support the yen and weigh on USD/JPY, but the article finds little evidence that it has added meaningful selling pressure to long-term US Treasuries. Any exchange-rate effect could influence Japanese import costs, though no direct feed-market impact is identified.
