The Bank of Japan said Wednesday that unrealized losses on its holdings of Japanese government bonds swelled to 9,433.7 billion yen at the end of fiscal 2023 from 157.1 billion yen a year earlier, hitting a record high for the end of a fiscal year.
   The central bank's JGB holdings increased 1.4 pct to a record 589,663.4 billion yen.
   In July and October 2023, the BOJ made policy tweaks to increase the flexibility of its yield curve control policy, which aimed to guide the key 10-year JGB yield around zero pct. In March 2024, it ended its negative interest rate policy.
   These moves by the BOJ fueled upward pressure on JGB yields, or downward pressure on JGB prices. The benchmark 10-year yield was above 0.7 pct at the end of March 2024, up from above 0.3 pct a year before.
   As the BOJ uses an accounting method that assumes JGBs are held to maturity, valuation losses are not reflected in its financial statements. However, if such losses raise concerns about the BOJ's financial position, it could cause turmoil in financial markets.
