On the New York Stock Exchange on the 15th, the Dow Jones Industrial Average temporarily fell sharply above $700.

Following a series of bankruptcies of U.S. banks, concerns about the deterioration of Credit Suisse, a major Swiss financial group, inflated sell orders immediately after the start of trading.

A market participant said, "There is growing uncertainty about how credit anxiety among financial institutions will spread in the wake of Credit Suisse's business problems, which will affect the business performance of U.S. banks."

In addition, in the New York foreign exchange market, the movement to sell the euro intensified, and the yen temporarily appreciated and the euro depreciated to the level of 1 euro = 139 yen.

The yen was also bought against the dollar as a relatively safe asset, and the yen price rose to the level of 1 dollar = 132 yen at one point.
