Assessment and forecast
According to Reuters, ECB Chief Economist Philip Lane said that on October 21, banks in the Eurozone could be under pressure if the USD capital source - the lifeline of the financial market - is interrupted, in the context of concerns about Mr. Trump's policies.
Concerns about a shortage of USD liquidity have appeared in the minds of central banks since Mr. Trump imposed trade tariffs and put pressure on the US Federal Reserve (Fed) earlier this year.
The Japanese Yen fell to its lowest level in a week after hardline conservative politician Sanae Takaichi was elected Prime Minister of Japan, as traders bet that her government could make interest rate prospects unpredictable and boost fiscal spending.
Takaichi, Japan's first female prime minister and leader of the ruling Liberal Democratic Party (LDP), won the House of Representatives vote on Tuesday to become head of the government. The move was anticipated by investors after she received support from the right-wing opposition party Ishin.
Mr. Volkmar Baur - foreign exchange and commodity analyst at Commerzbank - commented: "We believe that inflation and purchasing power of households will still be a key issue for the new government to maintain public support. Therefore, the new government may not support jobs to weaken the Yen," he added.
