LONDON, Jan 31 (Reuters) - The U.S. dollar headed for its worst start to a year since 2008 on Tuesday while world stock losses, already the biggest in six weeks, grew after widespread protests against President Donald Trump's stringent curbs on travel to the United States.
Investors' hopes for a fiscal boost to the world's largest economy under Trump have been tempered by controversial and protectionist policies that have seen him suspend travel to the United States from seven Muslim-majority countries.
Thousands took to the streets of major U.S. cities to oppose the travel ban, which also halts refugee arrivals, while marches in Britain added to pressure on Prime Minister Theresa May to cancel a planned state visit by Trump. stream of U.S. policymakers and business executives have also slammed Trump's stance. dollar edged down against a basket of six major currencies .DXY , on track for a 1.9 percent fall this month - its worst start to the year since the financial crisis.

On Monday, the U.S. S&P 500 Index .SPX fell 0.6 percent, its biggest fall in a month, though it remained well above levels seen before the Nov. 8 presidential election.

DOLLAR DOOM

In a possible sign of increased anxiety among investors, the safe-haven Swiss franc strengthened to a seven-month high of 1.0637 franc per euro EURCHF= on Monday.
Elevated uncertainty about Trump's policies, including a lack of detail so far on his plans for tax cuts and fiscal spending, offset optimism on the U.S. economy.
Data on Monday showed U.S. consumer spending accelerated in December while inflation showed some signs of picking up last month. core PCE price index, the Federal Reserve's preferred inflation measure, rose 1.7 percent on a year-on-year basis after a similar gain in November.
"We've seen a jump in U.S. economic sentiment after Trump's victory. But the improvement in hard economic data remains moderate," said Haruka Kazama, senior economist at Mizuho Research Institute.
"And if Trump takes more steps to limit permits for immigrants, that would surely boost inflation as the U.S. is now near a full employment."
The Federal Reserve, which starts its two-day policy meeting on Tuesday, is widely expected to keep interest rates unchanged as it awaits greater clarity on Trump's economic policies. prices dipped as rising U.S. drilling activity offset efforts by OPEC and other producers to cut output in a move to prop up the market.
