DOHA, April 26 (Reuters) - Qatar will allow its domestic gasoline and diesel prices to fluctuate in response to changes in global markets as it seeks to reduce waste of fuel and save money for the state budget.

Currently, local fuel prices are fixed at low levels, requiring the government to spend on subsidies to keep them down. From next month, prices will fluctuate monthly, the official Qatar News Agency (QNA) said on Tuesday.

Future prices will be based on a formula that includes global fuel prices, production and distribution costs within Qatar and prices elsewhere in the region, QNA said without giving further details of the formula.
