Moody's says governments lack tools to fight unexpected downturn -CNBC
* CNBC reports Moody's said there are growing signs of slowing global economic growth, and policymakers are lacking the conventional tools to deal with any unexpected negative shock.
* The agency's senior vice president of credit policy, Marie Diron, said muted global growth will not support a significant reduction in government debt or allow central banks to raise interest rates markedly.
* It points out the agency has kept its global growth forecast broadly unchanged, predicting G20 GDP growth to average 2.8% in 2015-2017, well below the 3.8% average of the five years before the global financial crisis.
