OPEC may consult on supply boost if rally continues

LONDON (Reuters) - OPEC may consult on whether the group needs to boost oil output before a scheduled meeting in September should crude oil prices keep rising, an OPEC source said on Friday.

"If the price keeps going up, OPEC may consult on an increase in production before it meets in September," the source said.

"In my view, any increase would have to be more than 500,000 barrels per day to have an impact on the price."
