The suspension of yen trading in Moscow Stock Exchange will have a depreciation effect on the yen. In this case, whether the exchange rate will fluctuate in both directions and whether it will reach equilibrium is worthy of attention. Usually, when a country's currency falls or other economic turmoil occurs, countries closely related to its economy will be greatly affected. At the same time, the existence of this situation has also affected the development of the national economy, especially in international trade. Because Japan's economy is inextricably linked with China, if so, it will inevitably affect the economic and trade exchanges between China and Japan, thus affecting the development of the global economy.

As we all know, exchange rate fluctuations have a great influence on a country's economy, and governments often intervene in the foreign exchange market to maintain the healthy development of their own economies. Monetary stability is very important for a country's economic security, such as price stability, exchange rate stability, foreign exchange reserve stability, cross-border capital flow and so on. Therefore, the foreign exchange market is an investment market that any country attaches great importance to, and it is a war without smoke. Like the stock market, the foreign exchange market is the lifeblood of the national economy and an important part of a country's economic development. The change of yen exchange rate has a great influence on the trend of the whole foreign exchange market. Under this influence, economic development and financial markets are bound to be affected, and problems such as unstable economic development environment and outbreak of risk emotions are highlighted, and investors will also face greater financial investment risks.

The fluctuation of exchange rate will also affect the prices of commodities, the production and operation of these commodities, trading enterprises and their upstream and downstream affiliated enterprises. It will also affect the trend of the whole futures market and other commodity markets, and bring more uncertainty to the development of the world economy. It can be seen that the foreign exchange market is not only the largest financial market in the world, but also the largest commodity market in the world.

Generally speaking, the fluctuation of the yen exchange rate will not only affect the vibration of the global financial market, but also affect the prices of bulk commodities, further triggering the global inflation crisis.
