Because oil consumers generally spend extra income fairly quickly, while governments (which collect the bulk of global oil revenues) usually maintain public spending by borrowing or running down reserves, the net effect of lower oil prices has always been positive for global growth. According to the International Monetary Fund, the fall in oil prices this year should boost 2016 GDP by 0.5-1% globally, including growth of 0.3-0.4% in Europe, 1-1.2% in the US, and 1-2% in China.
