BUENOS AIRES, Oct 22 (Reuters) - Argentine stocks closed with minimal losses on Monday despite gains on regional markets, dragged down by heavy selling in the banking sector after bonds fell, traders said.

"There was a great deal of volatility, leaving us with a selective market in which bank paper stood out as particularly weak once bonds slipped," said Hernan Labrone, an analyst with Fenix Financial company.
Trade volume on the broad stock market totaled a heavy 127.2 million pesos ($40 million). Of active shares, 25 advanced, 55 declined and 15 were unchanged.
Bond prices on the local market dipped 0.4 percent on average, hit by lingering concerns about U.S. economic health <AR/BONOS>.
The session's losses were led by dollar-denominated Par bonds, which slipped 1.8 percent.
