LONDON (Reuters) - The dollar steadied on Friday but was set for its first weekly rise in five weeks as doubts grew on the ability of other major global central banks such as the European Central Bank to start raising interest rates this year.While the prospect of another Fed rate hike has been virtually ruled out of money markets this year, markets have also whittled down the odds of the ECB raising interest rates on the back of weak economic data, weighing on the single currency.Money markets are assigning less than a 50 percent probability of an ECB rate hike this year and 80 percent likelihood of a rate hike from the Bank of England.Against a basket of its rivals .DXY, the dollar was broadly steady but was set to rise 0.4 percent on the week, its biggest weekly rise since mid-December.“For non-dollar currencies to make further gains from these levels, we have to see evidence that other major central banks are preparing to tighten policy,” said Manuel Oliveri, a currency strategist at Credit Agricole in London.
