DUBAI, Aug 22 (Reuters) - Gulf stocks may be soft on Monday after the global environment weakened, with oil and Asian equities pulling back amid concern that a U.S. Federal Reserve gathering this week in Jackson Hole, Wyoming may signal the U.S. central bank is gearing up to hike interest rates.

Brent crude LCOc1 has dropped 1.3 percent to $50.20 a barrel in Asian trade while MSCI's broadest index of Asia-Pacific shares outside Japan .MIAPJ0000PUS is down 0.7 percent. ID:nL3N1B302B

There is little fresh, positive news to push Gulf markets up. Dubai's stock index .DFMGI , last at 3,560 points, has retreated twice since last week from technical resistance at its April peak of 3,605 points.

Dubai-listed GFH Financial GFH.DU may attract interest after it said it had signed a memorandum of understanding with Bahrain's Bank Al Khair for a potential acquisition of a majority stake in the bank.

GFH said the acquisition would create a larger financial group with operations in the Gulf, Britain, Malaysia, Turkey, Pakistan and India, though a deal would depend on many conditions being met including due diligence, and no financial details were given.

Saudi Arabia's index .TASI , last at 6,212 points, is close to confirming a break of technical support on its early August low of 6,226 points. This would be very bearish, triggering a major right triangle formed by the highs and lows since April and pointing down to the 5,600-point area in the medium term.
