**[Key Trading Data: U.S. 10-Year Treasury Yield Rises to 4.086%]** BlockBeats reports on December 2 that, according to market data, influenced by the Bank of Japan's signal of a rate hike, the U.S. 10-year Treasury yield has risen to 4.086%, rebounding approximately 3.12% from the recent low of 3.962%. Japanese investors are the largest foreign holders of U.S. Treasuries. Market consensus generally holds that when the Bank of Japan raises interest rates and domestic Japanese Government Bond (JGB) yields begin to rise (e.g., the 10-year JGB yield surpassing the 1% threshold), Japanese funds will no longer need to endure exchange rate fluctuations to purchase U.S. Treasuries. Instead, they may choose to sell U.S. Treasuries and repatriate funds to invest in domestic bonds. A decline in U.S. Treasury prices would lead to higher U.S. Treasury yields, increasing global dollar borrowing costs and negatively impacting risk assets. The recent rise in the U.S. 10-year Treasury yield indicates that the market has already responded to the Bank of Japan's rate hike signal.
