The Singapore dollar strengthened slightly as the market focused on Trump's threats.

During the Asian trading session, the Singapore dollar slightly strengthened against the US dollar due to thin trading in some markets in the region as a result of holidays. Two foreign exchange strategists from Oversea-Chinese Banking Corporation's research department stated in a research report: "The market remains cautious, watching whether US President Trump will follow through on his threat to escalate the conflict with Iran." Trump threatened on Sunday that if Iranian leaders do not agree to reopen the Strait of Hormuz by Tuesday night, he will destroy all of Iran's power plants. Data from the London Stock Exchange Group shows that the US dollar fell 0.1% against the Singapore dollar to 1.2856 Singapore dollars.
