* U.S. oil product stocks up more than expected
* IEA lifts demand forecast, but emphasises economic risk
* Fall in equities harms sentiment towards oil
(Includes EIA inventory report, new prices)

London, Aug 11 (Reuters) - Oil fell below $79 on Wednesday, hammered by a build-up in U.S. product inventories, a nervous International Energy Agency report and a dive in global equity markets.
Gasoline stocks rose to their highest level of the past year on Aug. 6, according to the Energy Information Administration. [
] An accumulation in inventories can indicate lower demand.Tom Bentz, a broker at BNP Paribas Commodity Futures in New York, said: "This will give a negative twist to the market. "The inventories certainly are not going to stop the slide in prices."
U.S. crude for September <CLc1> delivery was down $1.81 at $78.44 a barrel at 1504 GMT. Front-month ICE Brent crude <LCOc1> fell $1.59 to $78.01 a barrel.
The market had already fallen sharply before the 1430 GMT EIA report due to a warning from the International Energy Agency (IEA) that demand was vulnerable to the risks of an economic slowdown and to sharp falls in global equity markets.
As well as a 400,000 barrel rise in gasoline stocks to 223.4 million barrels, the EIA also reported a 3.5 million barrel increase in distillate stocks. This more than counter-acted the potentially bullish news of a 3 million barrel fall in crude inventories.
The rise in gasoline and distillate stocks was higher than expected, although so, too, was the fall in crude inventories.
Earlier in the day, the IEA slightly increased its forecasts for global crude demand for this year and next in its August report from the previous month. It warned, however, that if the global economy proved weaker than expected, any rise in fuel consumption could be wiped out. [

OIL DEMAND
The U.S. government on Tuesday also modestly boosted its forecast for global oil demand growth this year and next, saying that developing countries would drive consumption despite a slower outlook for the U.S. economy. [

However, in July the country's implied oil demand slowed as expected from double-digit growth in the first half as firms scaled back refinery output and crude purchases from June peaks. [
