Dec 13 (Reuters) - Most Latin American currencies fell on Monday with Brazil's real declining 1% as inflation pressure and risks around the Omicron variant weighed, while a slew of upcoming central bank meetings kept investors wary of risk-driven assets.

Copper exporting peer Chile's peso gained 0.3% ahead of its central bank monetary policy decision on Tuesday, the first among its regional peers to meet this week. The Mexican and Colombian central banks are set to have their respective meetings on Thursday and Friday.

All three central banks are expected to hike interest rates sharply, and outline a hawkish stance going into next year as they move to contain a spike in inflation this year.

Rate hikes have been the norm across most emerging markets this year, barring a few outliers such as Turkey and China.

The focus is also firmly on the Federal Reserve's final policy meeting of this year, scheduled for Tuesday and Wednesday, at which the bank is expected to outline its plans for tapering stimulus and hiking interest rates next year.

Any early rate hikes by the U.S. central bank's policy-setting Federal Open Market Committee (FOMC) are likely to dent demand for risk-heavy assets, particularly in emerging markets.

"By speeding up the taper process, the FOMC will likely have its hands free to start hiking in the spring," Rabobank analysts wrote in a note.

"According to our projections, inflation will remain elevated, although declining, through most of next year. Given (Fed Chair Jerome) Powell’s current stance, this will likely lead the FOMC to hike in the spring of 2022."
