July 14 (Reuters) - Gulf stock markets fell in early trading on Monday, pressured by renewed U.S. threats of more tariffs, but losses were limited as investors grew accustomed to the volatility of U.S. President Donald Trump's policies.

Trump said on Saturday he would impose a 30 percent tariff on most imports from the European Union and Mexico starting August 1, despite lengthy negotiations.

The European Union said it would extend the suspension of countermeasures against US tariffs until early August and continue to push for a negotiated settlement. However, Germany's finance minister called for tough action if Trump goes ahead with the tariffs.

The Saudi index fell 0.2 percent, pressured by a 0.4 percent decline in Al Rajhi Bank shares.

However, ACWA Power's shares rose by more than 1 percent. The Saudi Press Agency reported that the company signed power purchase agreements on Sunday for renewable energy projects totaling 15 gigawatts, with investments worth approximately $8.3 billion.

Dubai's main index fell 0.3 percent, with Dubai Islamic Bank shares falling 0.9 percent and Salik shares falling 0.7 percent.

The index in Abu Dhabi fell 0.3 percent.

Investors are currently awaiting US inflation data for June, due out Tuesday, for further clues on the Federal Reserve's interest rate path.

Markets currently expect interest rates to be cut by just over 50 basis points by December.

The US Federal Reserve's decisions strongly influence monetary policy in the Gulf region, given that most of the region's currencies are pegged to the dollar.

The Qatari index fell 0.5 percent, pressured by a 0.8 percent decline in Industries Qatar shares.
