Is it a decline in bonds, or is US medium-term bond depreciation due to the FOMC agenda summary - Bank of Japan purchase reduction warning(some excerpts)

Futures temporarily rose in the bond exchange rate on the 23rd. In response to the fact that the Bank of Japan left the notification amount unchanged for the government bond purchase operation, a buyback was initiated. Meanwhile, the Bank of Japan's financial normalization observations are strong, and they continue to weigh on the market.
　　The Bank of Japan regularly buys government bonds at 10:10 a.m.notifications. Purchase amounts with a remaining period of 1 to 3 years or less, 3 years to 5 years or less, and 5 years to 10 years or less were all unchanged from the previous time. In the operation on the 13th, while upward pressure was applied to interest rates, the amount was unexpectedly reduced for 5 to 10 years or less, and observations intensified that the Bank of Japan would speed up the normalization of monetary policy. The previous operation on the 17th was left unchanged while continuous price reductions had been observed.
