DUBAI, Oct 4 (Reuters) - Middle East stock markets look set to consolidate in quiet trade on Sunday with very few domestic catalysts and a mixed global backdrop.

Brent oil LCOc1 last traded at just above $48 a barrel on Friday, lower than its level of above $49 when Gulf stock markets closed on Thursday. U.S. equities rose on Friday as worries about the U.S. economy after a disappointing jobs report gave way to a rally in beaten-down energy and materials stocks.

Modest trading volumes in the Gulf over the last week show many investors remain reluctant to take big positions because of factors such as the weak outlook for oil prices, uncertainty over the level of government spending and the war in Yemen.

In Qatar, the central bank sold only half the amount of Treasury bills which it originally planned on Thursday. Although the central bank governor then released a statement insisting that demand for the bills remained strong, commercial bankers said the scaled-back debt sale was a sign of liquidity tightening in Gulf banking systems because of cheap oil.

This will not necessarily hurt banks' profits, which could actually benefit if market rates rise, but it could in the long run slow economic growth and reduce liquidity available for equities investment. ID:nL5N1230DV

Dubai's stock index .DFMGI , which last closed at 3,619 points, has established a trading range of 3,500-3,700 points over the past month and may not break out of it without major domestic news or a change in the global environment.
