Widespread social unrest and shifting political winds in Latin America have complicated efforts to pinpoint where project finance work might take place in the region this year.

Yet, lawyers dedicated to Latin America say the pipeline remains intact: The need for infrastructure is simply too great to forgo investment. The Inter-American Development Bank estimates that the infrastructure investment gap in Latin America and the Caribbean is at 2.5% of gross domestic product, or around $150 billion per year.

Latin America's top economy, Brazil, is likely to see more private sector investment as its federal government steps back from financing infrastructure projects. Pockets of opportunity also remain in Mexico, even after the left-leaning government of the region's second-biggest economy sent shivers through the investment community by canceling a $13 billion airport for the capital that was already one-third built.

Less certain are prospects for the Andes, which saw social tensions boil over in the latter part of 2019, erupting first in Ecuador and soon after in Chile, Bolivia and Colombia. Meanwhile, deep economic troubles in Argentina and Venezuela—once mainstays for legal work—make sizable infrastructure investments in those two countries largely unviable for the time being. 

"This year will be a year of coming to terms with the new reality in Latin America, but it won't be an impediment to financing infrastructure," said Alexandro Padrés, a partner in Shearman & Sterling's project development and finance practice.

Investors looking to resize their risk and exposure to specific countries will drive merger and acquisition activity, while private equity groups searching for yield and multilateral institutions could fill a financing void left by more-cautious commercial banks.

Multilateral institutions will continue to finance projects in the region because their mandate is to drive development while achieving financial returns. As recently as December, the International Finance Corp. led a $657 million financing package for the first integrated liquefied natural gas-to-power project in El Salvador, one of the poorest countries in Latin America. 

Energía del Pacífico is the largest private sector investment in that nation's history. Once complete, the facility is expected to supply 30% of El Salvador's total energy demand and reduce energy imports from the current 25% to about 5% by 2023.

"They're not shying away because this is exactly when they're supposed to be in these countries: when there are real or perceived political concerns. Multilaterals bring stability and mobilize funds into jurisdictions," Padrés said.

Bob Kartheiser, chair of the Paul Hastings global infrastructure and energy practice, is optimistic that the main Latin American markets for U.S. dollar-based financing and M&A will be "robust" in 2020.

"The fundamentals remain compelling: We are talking about the basic building blocks of an economy with very long-term productive lives when we speak of energy and infrastructure. And in many areas, we see rising demand," Kartheiser said.

Raquel Bierzwinsky, a partner at Norton Rose Fulbright who splits her time between New York and Mexico City, dismisses the possibility that protests in places like Chile and Colombia could derail implementation of projects, "especially if these projects can help with demand for energy and reduce prices."

Colombia, for instance, depends heavily on hydroelectric power. That means, when it's the dry season there, prices go up significantly as generators turn toward older, fossil fuel-generated facilities that are more expensive. Colombia has the political will to attract greater private sector investment that could potentially drive down energy prices, Bierzwinsky said.

Elsewhere, the outlook for energy projects became cloudy in Mexico when leftist Andrés Manuel López Obrador won the presidency in 2018 on promises that he would strengthen state oil and electric companies. Clean energy auctions were postponed, for instance, spooking solar and wind investors. 

Yet, the change in leadership of Latin America's second-biggest economy hasn't completely dampened project finance there. 

The energy sector reform under the previous administration allowed, for the first time, for private electricity auctions in Mexico. Those who won those private electricity auctions must still obtain financing—that means work for lawyers—while state electric firm CFE is slated to award contracts to build five combined-cycle gas plants. 

"People have already invested, and they're looking for ways to sell power," explained Bierzwinsky. "The demand is still there for financing."

Mexico has a glaring need for electricity: The country sees 3-3.5% growth in electric demand each year. In April, power blackouts rolled through the Yucatan Peninsula, a tourist hot spot, as natural gas supplies failed to keep pace with demand.

The most work this year, though, could come from Brazil, a $2 trillion economy that's looking to trim bureaucracy and open more to private investment under pro-business President Jair Bolsonaro. 

"In Brazil, the infrastructure has not kept up with the development of the country. There's a huge deficit in infrastructure, which is a cap for growth," explained Grenfel Calheiros, head of the São Paulo office at Simpson Thacher & Bartlett.

Government development bank BNDES is pulling back from infrastructure projects in Brazil, while interest rates in the country hover at an all-time low 4.5%. It's a recipe for more creative, privately-sourced financing.

"People may have to resort to project finance—previously they didn't have to because they had access to cheaper, government financing," Calheiros added.
