Japan 30-year bond yield rises 6bp to 4.200%; 10-year up 5bp to 3.11%

The parallel rise across the long and ten-year tenors points to a repricing of the entire Japanese curve rather than a single-maturity distortion, which matters for global duration benchmarks given Japan's role as an anchor for yen funding. For crypto and RWA markets, the relevant channel is the cost of yen-denominated leverage and the relative appeal of carry trades that have historically fed risk appetite. Whether this steepening persists or reverses as domestic demand for duration reasserts itself is the open question.
