Peso Breaks Through 18 as US Yields Hit 2007 High

Mexico's peso crossed the 18-per-dollar threshold on September 29–30, marking its weakest close since March, as US Treasury yields hit their highest levels since 2007. The IPC itself rose 0.20% to 65,071, supported by heavyweight Cemex and Femsa, but the currency weakness—driven by higher US bond yields and renewed Federal Reserve rate-hike bets—overshadowed equity gains. The peso weakness signals growing capital outflow pressure on Mexico as US rates attract foreign investors away from emerging markets.

Chile and Peru Copper Tracker Rises Despite Rate Headwinds

The copper-tracking fund (CPER) rose to US$39.93 on Tuesday, September 29, gaining 0.6% as copper futures stabilized, even as a firmer US dollar and Fed rate-hike bets weighed on prices. Chile and Peru together supply one-third of global mined copper, making the sector critical to both IPSA and BVL performance. However, Chile's IPSA fell 0.73% on September 29 in local trading, and Peru's BVL faces ongoing headwinds from lower traded volumes—down 76% from pre-pandemic levels as pension fund withdrawals persist.

Colombia COLCAP Tumbles 0.79% Ahead of BanRep Decision

Colombia's COLCAP index fell 0.79% to 2,559 on September 29, with Ecopetrol tracking oil lower as energy prices slipped. The peso firmed slightly to 3,330 per US dollar ahead of Banco de la República's widely anticipated rate decision expected on September 30. Market volatility reflects investor uncertainty over whether BanRep will hold its 12.0% policy rate or signal further moves, as inflation dynamics and IMF program requirements collide.

Mexican Steel Under Pressure as 50% US Tariff Remains in Force

Latin American steel shares fell on September 28–29, with Ternium losing 1.61% as the 50% US duty on Mexican steel remained unresolved. The tariff dispute continues to weigh on nearshoring sentiment, complicating Mexico's manufacturing export competitiveness despite record FDI inflows earlier in 2026. This drag offset gains in construction-linked stocks like Cemex, which rose to lead the IPC despite broader peso weakness.

Local view

Spanish-language Mexican media noted that the IPC "failed to sustain the 65,000-point level" on September 29, with Investing.com México reporting technical weakness despite nominal gains. Coverage emphasized the peso's breach of 18 per dollar as the headline risk, with Expansión and El Financiero flagging US Treasury yields and Fed rate expectations as the primary driver of currency depreciation. Milenio reported the peso had erased all 2026 gains, citing energy inflation concerns in the US as an additional weight.

In Chile, Diario Estrategia reported the IPSA fell 0.73% on September 29, with copper volatility and energy sector weakness cited as key headwinds. Santiago-based coverage noted that the recent decline in traded volumes and pension fund equity allocations continue to constrain liquidity.

Colombian media reported COLCAP's 0.80% drop on September 29, with Investing.com highlighting oil sector exposure as the primary drag. BanRep's imminent decision dominated pre-market commentary as investors weighed rate expectations against broader inflation and growth concerns.
