[The Bank of Japan learned that it will not rescue the sharp fall of Japanese treasury bond bonds caused by the high market] On February 4, Kim Shin Data reported that Prime Minister Takashi Zaomiao should not expect the Bank of Japan to restrain the sharp rise of Japanese treasury bond yields, because the intervention costs are high, including the major risk that may lead to an unpopular devaluation of the yen. Last month, Japanese government bonds plummeted, causing turbulence in the global bond market. Previously, Takashi announced early elections and promised to suspend food taxes for two years, causing market concerns that fiscal spending would further expand, making Japan's already huge debt burden even heavier. Despite the market volatility triggering internal warnings from the central bank, three sources familiar with the central bank's thoughts said that the risks of intervening in the bond market at this stage outweigh the benefits. According to insiders, the central bank believes that recent market fluctuations have not yet reached its very high intervention threshold. Sources point out that the Bank of Japan only intervenes in panic selling triggered by speculative trading or when the market is in a state of disorder where the central bank is the final market maker, and these situations have not yet occurred.
