NEW YORK, July 9 (Reuters) - U.S. crude oil futures dropped on Friday, hitting the lowest level since mid-May, as the latest forecast from the International Energy Agency stirred more worries about oil demand.

Global oil demand will rebound 1.7 percent next year, but the demand outlook for this year was "effectively unchanged," -- down 2.9 percent, or 2.5 million bpd compared with last year, the Paris-based International Energy Agency, adviser to 28 industrialized nations, said in its latest monthly forecast.

David Fyfe, head of the IEA's oil industry and market division, said the extent of recovery in world oil demand would rest on the performance of the global economy and prices.

On Thursday, NYMEX crude futures ended higher, snapping a six-day losing streak, amid bargain hunting, a drop in jobless benefit claims and a rally in gasoline futures.

But analysts agreed that brimming product supplies and weak demand continued to weigh on the market.
