BUENOS AIRES, May 26 (Reuters) - Argentine stocks closed slightly higher in light trade on Monday, as high global crude prices boosted shares in the local listing of Brazil's state-run energy company Petrobras.
The benchmark MerVal index .MERV inched 0.19 percent higher to close at 2,239.38 points after shedding 0.98 percent earlier in the session.
Volume was a slack $6.9 million on the broad market, where 24 issues advanced, 29 declined and 10 ended unchanged.
Traders were watching a standoff between the government and farm leaders who are locked in a two-month dispute over grains export taxes that has raised fears of a prolonged political conflict.
The government called off talks with farmers scheduled for Monday, a day after farm leaders held a rally of some 200,000 people.
Local trading in Argentine government bonds was largely inactive because of the Memorial Day holiday in the United States, traders said.
