the yen

Japan has begun scaling back its ultra-loose monetary policy in an effort to prop up the yen, which has fallen sharply against the dollar. Commentators note the move is being helped by expectations of looser policy from the US Federal Reserve, dubbed Japan's 'American friend', which narrows the interest rate gap driving the currency's decline.

US Treasury yields have climbed into 5% territory as the Federal Reserve delivered its first interest rate hike in over three years, while Japan also moved to raise rates. Commentators are examining how simultaneous tightening by the two central banks could strengthen the yen and pressure tech-heavy indices like the Nasdaq 100 and FANG+ stocks.

The US dollar slipped while the Japanese yen rallied after remarks from Japanese officials, and oil prices eased, weighing on currency markets. Traders are watching whether the yen's move signals potential intervention concerns or a shift in Japanese policy talk, while softer oil prices are reshaping expectations around inflation and central bank policy.

Former BitMEX chief executive Arthur Hayes says Bitcoin could climb to $1 million, citing Japan's fresh stimulus measures as a catalyst. He argues that renewed monetary expansion by the Bank of Japan will weaken the yen and push investors toward hard assets, with Bitcoin a prime beneficiary. His forecast is circulating widely among crypto market watchers, many of whom treat his bold price calls as a barometer of speculative sentiment.

NTT Docomo will raise the monthly fee for its ahamo low-cost mobile plan from December, adding 165 yen per month. Older OCN Mobile ONE plans are also affected by the change. The modest size of the increase is being read as a cautious move, with Docomo apparently mindful of competition from rival carriers' discount plans and reluctant to push prices higher.
