"The shutdown so far has been fairly benign. The effects on the markets have been relatively low," Laura Kodres, assistant director of the IMF's Monetary and Capital Markets Department.
Global stock markets' reaction to the partial US government shutdown yesterday was muted. Markets generally had priced in that outcome amid an entrenched battle between Republicans and Democrats in the US Congress over a budget for the 2014 fiscal year that began that Tuesday.
"Any time we have an increase in uncertainty, that can have an effect on demand and potentially the supply of credit," she said during a news conference in Washington to unveil a new IMF report on global financial stability.
Households and businesses would likely rein in their use of credit because "it's very unpredictable to determine what will happen next," she said.
Banks could also become worried about the situation and cut back on credit, she added.
Most economists predicted the shutdown would shave a few tenths of a percentage point from fourth-quarter US economic growth, if it lasts only a week or two.
