Colombians voted narrowly against a pact with the Revolutionary Armed Forces of Colombia (FARC) in Sunday's referendum, plunging the nation into uncertainty.

MSCI's iShares Colombia Capped ETF was down 3.5 percent, and Colombian U.S. dollar bonds opened multiple points lower on Monday. The Colombian Capitalization index was down more moderately, slipping 0.8 percent, with belwether Ecopetrol actually up slightly as oil prices rose.
The referendum result dented President Juan Manuel Santos' political standing, just a week before the government planned to unveil a tax reform that looks to hike revenue by between 1 percent and 2 percent of gross domestic product.
Even though it still has a legislative majority, the government may now be forced to water down the tax proposals due to a newly-emboldened opposition.
"The outcome was definitely a surprise and markets have backed up a bit and the currency has come off sharply," said Kevin Daly, a member of Aberdeen Asset Management's investment committee.
