The economic cost of the U.S. government shutdown will keep the U.S. dollar under pressure this week, while the hit on business and consumer confidence could force the Federal Reserve to delay the withdrawal of stimulus until next year, according to CNBC's latest market survey of currency traders, analysts and strategists.

Nearly 89 percent (24 out of 27 respondents) believe the U.S. dollar will slide this week, according to CNBC's latest poll of currency market sentiment. Just 7 percent (2 out of 27) say the dollar will gain, while one respondent is 'neutral' and expects the dollar to trade around current levels.
