Japan is really going to throw caution to the wind this time.。Just days after China announced its trillion-dollar national debt plan, Japan also announced a huge economic stimulus package totaling 17 trillion yen, equivalent to 820 billion yuan.。first, china's national debt program is aimed at promoting economic growth and providing financial support for development, which is a large number, but china's economic scale is correspondingly huge,。The situation in Japan is slightly different, their economy is relatively small, only 1 / 4 of China's, but the amount of stimulus they announced is huge, why？Because the problems they face are different。Japan's main goal is to save their currency, the yen, whose value fell sharply at one point, posing a threat to their economic stability。In order to maintain the yen exchange rate, the most direct way is to buy dollars through central bank intervention in the market and then convert them into yen。However, the U.S. is reluctant to see Japan continue to sell their U.S. bonds, which is complicating this approach。Another solution is to promote economic growth.。But Japan's economic growth has been sluggish。This year, the International Monetary Fund forecasts that Japan's real economic growth rate will be only zero..5%, may be overtaken by other countries, from the world's third to fourth。Raising interest rates is another option.。But since Japan's debt is already high, which could exacerbate fiscal pressures, they chose to implement a massive economic stimulus plan to stimulate growth, raise inflation and lower the yen.。However, this stimulus plan also has risks, Japan's national debt is already quite high, has not yet taken into account the local government debt, if an additional 1 trillion national debt, will be a greater burden on the national finances。In summary, both China and Japan are taking steps to address their respective economic challenges。Japan's stimulus plan aims to save currency value。These policies are accompanied by risks and challenges, and do you think this Japanese stimulus is useful？
