GROZNY, Russia, July 15 (Reuters) - Russia might decide by the end of July whether to reinstate a gasoline exports ban from August if the situation on the domestic fuel market "gets tense," such as in the case of shortages, Deputy Prime Minister Alexander Novak told reporters on Monday.

He said the domestic fuel market has been stable so far, but there have some difficulties with a popular gasoline, Ai-95 grade, which are being dealt with.

"If the situation gets tense, we will not extend the waiver for gasoline exports," Novak said. (Reporting by Olesya Astakhova; writing by Vladimir Soldatkin; Editing by Bernadette Baum)
