The dollar fell against the yen on Tuesday as U.S. stock futures erased gains and traded lower in a sign some investors remain concerned about the economic shock posed by the coronavirus pandemic.
The pound clawed back some recent losses against the dollar, but sentiment for sterling remains fragile after British Prime Minister Boris Johnson was moved to intensive care after his coronavirus symptoms worsened.
The yen was supported against major currencies after Japanese Prime Minister Shinzo Abe unveiled fiscal stimulus worth almost $1 trillion to offset the economic impact of the coronavirus.
Traders warned that further gains in the yen may be limited because Abe has agreed to declare a state of emergency for Tokyo and other parts of Japan to slow coronavirus infections.
Many investors are looking for signs of a peak in the pandemic, but some analysts warn of volatility given the unpredictable nature of the previously unknown virus.
