U.S. is outlier in push to boost IMF resources

The global financial system is still on shaky ground and the multinational institution that's tasked with propping it up needs more money.

"We need more resources," International Monetary Fund managing director Christine Lagarde said in a recent speech.

The IMF, which acts as the United Nations of global finance, is seeking to raise $500 billion to meet an estimated $1 trillion worth of funding needs over the next few years.
