[The Bank of Japan recorded a record loss in its holdings of Japanese treasury bond bonds in the last fiscal year] On May 27, Jinshi Data, the Bank of Japan announced on Wednesday that its holdings of Japanese treasury bond in the last fiscal year had recorded a record loss, highlighting the heavy valuation hit on its holdings caused by the bank's move to higher interest rates. In the fiscal year ended March, the unrealized loss of its Japanese treasury bond bond position was 45.441 trillion yen (about 285.26 billion dollars), higher than the 28.625 trillion yen recorded in the previous fiscal year, and also the largest loss of the central bank since the release of comparable data. Bank of Japan officials have long insisted that such losses do not affect monetary policy decisions, as the bank intends to hold these bonds until maturity, which means that these book losses will not be realized. Since withdrawing from the negative interest rate policy in 2024, the Bank of Japan has been gradually but steadily tightening monetary policy, which has pushed up the yield of Japanese treasury bond bonds. Due to market concerns, as the Middle East conflict pushes up oil prices, the Bank of Japan may fall behind in combating inflation, and this upward trend has recently accelerated. If this situation continues, the book losses of its Japanese treasury bond may deepen. Another factor driving up the yield of Japanese treasury bond is the government's fiscal stimulus plan, which has increased the market's concern about Japan's debt burden.
