Colombia's central bank shocked markets with a surprise 25-basis-point rate hike to 12.25% on September 30, defying analyst expectations for a hold, while Mexico's peso tumbled 4% as carry-trade liquidation gripped Latin America and the US 10-year yield surged. Chile's peso hit its weakest level in over a year, signaling broad currency weakness across the region despite Banxico's steadfast 6.50% hold.

Colombia's Central Bank Delivers Surprise 12.25% Rate Hike, Defying Market Consensus

On September 30, Colombia's Banco de la República raised its policy rate by 25 basis points to 12.25%—a move that shocked economists, most of whom had predicted a hold at 12%. The board voted 4-2-1 in favor (four for the hike, two to hold, one for a 50-bp increase). Governor Leonardo Villar cited persistent inflation pressures and inflation expectations above the central bank's 3% target as drivers of the surprise tightening. The decision immediately pressured Colombia's stock market, with the COLCAP falling 0.38% to 2,549 on September 30 and 0.75% to 2,530.05 on October 2, though the peso initially firmed to around 3,300 per dollar before slipping.

Mexico's Peso Plummets 4% as Speculative Positions Unwind

The Mexican peso fell sharply during the week, losing approximately 4% as speculators aggressively cut long bets on the currency. CFTC data show net long positions fell to 52,402 contracts on September 29. The peso closed at 18.0687 on September 30 and weakened further to 18.30 on October 2, erasing all 2026 gains amid broad carry-trade liquidation. Banxico kept its benchmark rate unchanged at 6.50% on September 24, signaling a patient stance. Governor Victoria Rodríguez Ceja stated on September 29 that Mexico need not copy US rate moves and emphasized the country's separate economic cycle from the United States. Despite Banxico's hawkish rhetoric on inflation (which remains above the central bank's 3% target, with expectations for a return to goal only in late 2027), the peso's weakness reflects investor concerns about the deteriorating carry trade.

Carry-Trade Unwind Crushes LatAm Currencies; Chile's Peso at 14-Month Lows

Rising US Treasury yields and volatility are triggering a broader unwind of emerging-market carry trades, with LatAm currencies under particular strain. Chile's dólar observado weakened to 983.84 on October 2—its weakest level in over a year—marking a fourth consecutive daily depreciation. MUFG analysts noted that implied volatility spikes are squeezing long leveraged positions in Mexican pesos and other LatAm FX. Mexico's S&P/BMV IPC fell 1.38% to 64,214.36 on September 30, while Brazil's Ibovespa rose 1.37% and the real firmed 0.53%, showing a relative resilience contrast. The weakness is partly driven by the US 10-year Treasury yield reaching 5.34%—a level not seen since 2002—pressuring the rate-differentials that had underpinned carry positions.

Banxico Signals Independence; Mexico Waits Until Late 2027 for 3% Inflation Target

On September 24, Banxico's board unanimously held its policy rate at 6.50%, citing Mexico's distinct economic cycle and the absence of demand-side inflation pressures despite currency depreciation. The central bank has now missed its 3% inflation target for 75 consecutive months, with internal forecasts suggesting only late 2027 as the return date. Former deputy governors and critics have questioned Banxico's independence, arguing the bank has fallen behind the inflation curve. Private-sector surveys, however, lowered their 2026 inflation forecast while raising GDP growth estimates, suggesting some stabilization in expectations.

El Economista's "Claves Económicas" column highlighted the week's pivotal rates decisions and currency volatility, noting that remittances and the trade balance remain critical variables for peso stability. Colombian outlets including Portafolio and Cambio reported widespread political backlash to BanRep's surprise hike, with former president Gustavo Petro criticizing monetary policy's impact on growth, though Governor Villar stood firm on inflation control. Mexican press, including Expansión, framed the peso's weakness as a collision between the Fed's higher rates and Mexico's carry-trade unwind, with analysts warning that USD/MXN could test 18.50.
