DUBAI, June 29 (Reuters) - Stock markets in the United Arab Emirates may have a firm tone in light trade on Thursday as oil prices have continued to improve from low levels, while banks may get a boost as banking shares overseas have surged.

Brent crude oil rose for a sixth straight session on Thursday to its highest since June 19 and was trading at $47.50 a barrel.

The prospect of higher interest rates from central banks around the world, including Britain and Canada, bolstered banking stocks and helped the S&P 500 score its biggest one-day percentage gain in about two months on Wednesday.

Asia has followed on Thursday with Japan's Nikkei adding 0.5 percent and MSCI's broadest index of Asia-Pacific shares outside Japan rising 0.8 percent to its highest since May 2015.

Banking shares dominate Abu Dhabi's index , but trading volumes may stay near recent low levels as some traders are on their summer break, while others are waiting for second- quarter earnings before adding to their positions.

Short-term technical indicators show Dubai's index is bearish, according to analysts at NBAD Securities, who put support at 3,366 points; they note the index is below the 20-day simple moving average of 3,393 points.

"If volumes remain near the previous day's extremely low levels, the market will be bound to this bearish trend for a while," said a Dubai-based trader.

Markets in Riyadh and Doha are closed for an Eid al-Fitr break and will resume trade on July 2. Egypt is also closed for a public holiday.
