The head of the International Monetary Fund appeared to be making headway Saturday in her drive to boost the institution's financial firepower so that it can help Europe prevent its crippling debt crisis from further damaging the global economy. Christine Lagarde, who replaced Dominique Strauss-Kahn as managing director of the fund six months ago, is trying to ramp up the IMF's resources by $500 billion so it can help if more lending is needed in Europe or elsewhere. Insisting that the IMF is a “safe bet” and that no country had ever lost money by lending to the IMF, Lagarde argued that increasing the size of the IMF's resources would help improve confidence in the global financial system. If enough money is in the fund the markets will be reassured and it won't be used, she said, using arguments similar to those that France has made about increasing Europe's own rescue fund. “It's for that reason that I am here, with my little bag, to collect a bit of money,” she said at the World Economic Forum in the Swiss Alps town of Davos. Her plea appeared to find a measure of support from ministers of Britain and Japan, sizable IMF shareholders that would be expected to contribute to any money-raising exercise.
