Yesterday's Recap

Equity markets showed regional divergence on September 16 with MSCI Peru advancing 0.85% to 89.27 on copper strength while MSCI Chile declined 0.46% to 38.95 and MSCI Colombia remained unchanged at 9.02. FX markets recorded a sharp 3.73% jump in USD/PEN to 3.37, reflecting notable sol depreciation, whereas USD/COP edged 0.02% higher to 3,122.91 and USD/CLP eased 0.14% to 953.58. Commodity prices moved in opposing directions as copper surged 2.71% to 6.61, bolstering export revenues for Chile and Peru, while Brent crude plunged 6.41% to 99.05, weighing on Colombia’s oil-linked fiscal position, and gold slipped 0.21% to 4,378.30.

Sovereign yields increased across the board with Colombia’s 10-year yield rising 7 bp to 12.66% and Peru’s 10-year yield advancing 11 bp to 6.59%. No macroeconomic data releases occurred in Colombia, Chile or Peru, leaving market participants to focus solely on commodity price signals and external flows. Record August gold output at Aguia Resources’ Santa Barbara project in Colombia offered a positive note for future royalty streams though it did not yet alter aggregate export figures.

The Day Ahead

The economic calendar remains empty for Colombia, Chile and Peru with no CPI prints, GDP releases, trade balances, central-bank meetings or sovereign auctions scheduled. Market attention will therefore stay on global commodity prices, particularly copper and Brent crude, given their direct fiscal and current-account implications for the three economies. Copper’s recent advance should continue to support mining royalties and tax receipts in Chile and Peru while any further Brent weakness could widen Colombia’s fiscal gap through lower Ecopetrol revenues.

FX markets may see continued volatility in the PEN after yesterday’s sharp move, with COP and CLP likely to track broader risk sentiment. Investors will also monitor any updates on lithium-related projects in Chile that could influence medium-term capital flows.

Other Economic Notes

Copper’s 2.71% rally provides direct fiscal relief to Chile and Peru where mining exports dominate current-account balances and government revenue through royalties and taxes. Sustained higher prices should widen fiscal surpluses and eventually support local currencies, though immediate FX reactions remained muted. ↓ p.2

Other Economic Notes (continued)

Brent’s steep decline poses downside risks to Colombia’s oil-dependent fiscal accounts and could pressure Ecopetrol-linked revenues if prices remain lower for longer. Gold’s minor pullback had limited immediate impact on Colombia despite the positive project-level news from Aguia Resources. Broader commodity strength continues to differentiate Andean fiscal trajectories from more diversified emerging-market peers.

Global Macro News

Global copper prices near multi-year highs on sustained AI and EV demand, directly benefiting Chile and Peru’s mining sectors and improving their terms of trade. Brent crude’s sharp drop reflects weaker global demand signals and could ease import costs for net importers while hurting Colombia’s export receipts. Gold’s slight retreat occurred against a backdrop of elevated safe-haven buying elsewhere, yet Colombian gold projects still recorded record grades that may lift future royalty collections.

Argentina’s strong-peso policy under Milei continues to constrain growth and offers a regional contrast to the more flexible exchange-rate regimes in the Andean bloc. Broader emerging-market flows remain sensitive to U.S. rate expectations, with any further dollar strength likely to pressure the PEN after its recent depreciation.

Copper’s outperformance relative to nickel underscores shifting industrial metal demand patterns that favor Andean producers over other commodity exporters.

Continuation

Andean Central Banks Watch

BanRep maintains its relatively hawkish stance within the region given Colombia’s persistent inflation pressures, keeping policy rates elevated compared with peers and limiting room for near-term easing. BCCh has pursued the most aggressive rate-cutting path among the three central banks, reflecting Chile’s faster disinflation progress and greater sensitivity to mining-cycle fluctuations. BCRP continues to deliver the most stable policy trajectory in the Andean group, with limited FX intervention and a focus on reserve accumulation to buffer external shocks.

Divergences in rate paths remain pronounced: Colombia’s tighter stance contrasts with Chile’s front-loaded cuts while Peru’s measured approach supports currency stability. None of the three banks released new policy decisions or inflation-target updates on September 16, leaving forward guidance unchanged. FX intervention remains a latent tool for BCRP should PEN volatility persist, whereas BanRep and BCCh continue to prioritize inflation-target credibility over direct currency management.
