The U.S. Federal Reserve announced an open-ended asset purchase program on Monday. The central bank said the program will run in the "amounts needed to support smooth market functioning and effective transmission of monetary policy to broader financial conditions and the economy."
"The Fed has committed to buying debt, not just government and residential mortgage backed securities but now for the first time commercial mortgages (paper backed by office buildings and the like)," Ray Attrill, head of foreign exchange strategy at National Australia Bank, wrote in a note.
"Unlike during the post (global financial crisis) when there were quantitative limits on how much the Fed would buy each month, purchase amounts are now unlimited," Attrill said.
Meanwhile, Germany is set to unveil major stimulus measures as the death toll from the virus rises throughout Europe. Both the region and the U.S. have seen a dramatic increase in the number of infected in recent weeks.

Goldman Sachs' Zach Pandl told CNBC on Tuesday morning that there is a "strengthening case for dollar intervention at this point."
"We do think that there is a rising case for direct intervention to weaken the dollar by U.S. authorities," Pandl, who is co-head of global foreign exchange, rates and emerging markets strategy at Goldman Sachs, told CNBC's "Squawk Box" on Tuesday. "This is something that is fairly uncommon, so we need to be taking it somewhat seriously, but this is the type of environment that intervention is designed for.
"The Fed and the Treasury intervene to combat disorderly markets, and that's definitely what we've been seeing in foreign exchange over the last couple of weeks," Pandl said.
Oil prices were up in the afternoon of Asian trading hours, with international benchmark Brent crude futures 4.33% higher at $28.20 per barrel while U.S. crude futures added 4.97% to $24.52 per barrel.
