SAO PAULO, Nov 23 (Reuters) - Equities markets across Latin America fell on Thursday amid light Thanksgiving trading, led by the blue-chip IPSA index in Chile, where investors are still jittery over a weak performance by conservatives in elections over the weekend.
On Thursday leftist Chilean presidential candidate Alejandro Guillier, competing in a run-off after coming second in a first round on Sunday, said he was open to eliminating Chile's quasi-private pension fund system for a state-run model.
Additionally, workers at BHP Billiton Ltd's BLT.L BHP.AX major Escondida copper mine in Chile walked off the job temporarily, spooking investors in the mining-dependent country. The IPSA .IPSA closed down 1.84 percent.
In Mexico, the S&P/BVM IPC .MXX index slipped by 0.13 percent after data showed a surprise acceleration in inflation in early November, complicating the central bank's hopes of dampening price pressures before the end of 2017. in miner Grupo Mexico GMEXICOB.MX put downward pressure on the stock index, slipping 2.08 percent.
Brazil's Bovespa .BVSP dipped 0.04 percent as President Michel Temer continues to face difficulties pushing through a pension reform seen as key to shoring up fiscal health.
On Wednesday night, the congressman in charge of drafting the reform presented a new version in an event at Temer's official residence. However, attendance was poorer that expected, which some analysts interpreted as a sign of relatively weak support for the measure.
Among the poorly performing major constituents of the index was steelmaker Usinas Siderurgicas de Minas Gerais SA USIM5.SA , whose shares fell by 1.28 percent.
