But a statement https://home.treasury.gov/news/press-releases/sm927#.Xl5OpmGbM1F.twitter from a meeting of G7 finance ministers and central bank governors on Tuesday only said they stood "ready to take actions, including fiscal measures where appropriate".
"I don't think there is a whole lot they can do. You may see some rate cuts in the U.S. but rates are already pretty low in the rest of the world," said Scott Brown, chief economist at Raymond James in St. Petersburg, Florida.
As of Monday, traders had fully priced in a 50 basis point reduction in borrowing costs from the Fed this month, according to CME Group's FedWatch tool, compared with zero just a week ago, as the virus spreads faster outside China.
The epidemic, which has crippled tourism, disrupted global supply chains and raised alarms of a recession, has now killed more than 3,000 people and spread to more than 60 countries.
