French IG Group's chief market analyst Alexandre Baradez warned that Macron's unexpected announcement of the election triggered a surge in the European Stoxx 50 volatility index, and the volatility of the US stock market may follow suit to adapt to European pressure. Unlike other events such as the European sovereign debt crisis or Brexit, the pressure of the VIX index on the European market is almost negligible. He cautioned that in the past, there has always been some form of adjustment between the fear indexes of the two continents, and the difference between the two is unlikely to remain at its current level. "I do not think that the situation where the volatility of the United States does not adjust can continue for another two weeks, because both the global and the US markets need to consider European risks."
