The global lender is "quite a bit away" from exhausting its $US1 trillion in total lending capacity and is working to identify new sources of funding and liquidity for member countries, IMF officials said during a conference call with reporters on Wednesday.

More than 80 member countries, mostly emerging markets, have already requested some $US20 billion in emergency zero- and low-interest loans from the IMF, they said, and IMF staff were working to process those requests as quickly as possible.

"We see the crisis shifting to emerging markets. Low-income countries are now all seeing the pickup in infection rates that we've seen in China and the advanced economies," said one of the officials.

Funding needs were greater in some of those economies due to significant capital outflows and a sharp drop in commodities prices, the official added.

The virus has infected more than 878,000 people and killed 43,412 around the world.

In addition to existing programs, the IMF is looking at reviving a proposal for a short-term liquidity line that was developed several years ago, and could be quickly implemented if approved by members, the officials said.

While it was critical to help countries respond to the virus, the IMF could not deviate from its fundamental principles calling for debt to remain sustainable, said one of the officials.

The officials said there was broad support for a joint proposal by the IMF and the World Bank calling on official bilateral creditors to suspend debt service payments - also known as a standstill - for countries that needed help during the current crisis.

That did not mean the IMF was pressing for a broader round of debt forgiveness, said one of the officials.
