Yesterday night (Thailand time), the US stock market recovered from relaxed polices, helping the S&P 500 increase by 1.2 per cent. However, the Stoxx Europe 600 decreased by 0.1 per cent from a strengthened euro and pound.

According to the FOMC, the average inflation target and yield curve could change in the future.
The dollar index fell to 0.45 per cent, its lowest point since May 2018.
In Thailand, the baht strengthened slowly, due to the purchasing of dollars.
