Top developments
US 10-year yield briefly tops 5%
On September 15, the benchmark US 10-year Treasury yield briefly touched 5.011%, its highest level since October 2023, before easing amid a broader global sell-off. For the daily LatAm rates wrap, the move matters because higher US yields transmit directly into peso levels, carry-trade appetite and the pricing of Fed spillovers.
Mexican peso drifts back toward 17 per dollar
El Financiero reported on September 14 that the Mexican peso returned to the “floor” of 17 units per dollar ahead of the next Federal Reserve announcement, after trading at 16.9705 on September 11, when it appreciated 0.17%. The near-17 level is a practical marker for carry-trade appetite and peso stability, especially as investors position ahead of the Fed.
Colombia: COLCAP slips while COP weakens to 3,103.10
Rio Times reported on September 15 that Colombia’s COLCAP closed at 2,588.25, down 0.06%, while the peso slipped to 3,103.10 per dollar, with oil, Fed nerves and local data keeping trade cautious. That mix matters for TES and carry appetite because the source links the cautious trade directly to oil, Fed nerves and local data.

Chile: equities rise, but CLP falls to 957.12
Rio Times reported on September 15 that Chile’s S&P IPSA rose 1.09% to 11,342 on September 14, led by SQM and retailers, while the peso weakened to 957.12 against the dollar. The split matters for BCCh-related positioning because local equities can improve even when the peso remains exposed to global yield shocks and commodity-linked flows.

Local view
Mexican and Colombian press focus on Fed fear, not local policy
El Financiero described the peso as “se asusta” by the upcoming Fed announcement and said it moved back to the 17-per-dollar level. La Jornada, in a September 10 report, tied investor sentiment directly to the rise in US bond yields, while GBM said Mexican markets were pointing to weekly losses even as the peso held below 17. In Colombia, El Tiempo said the peso entered the week strengthened, with the Fed’s rate decision dominating the market’s attention.
Context & numbers
- US 10-year Treasury yield: briefly 5.011%, the highest since October 2023, before easing.

On the radar
- The Federal Reserve decision is the dominant short-term driver for MXN, COP and CLP, according to Mexican and Colombian market commentary.
- Watch whether the US 10-year yield can sustain moves above 5% after briefly touching 5.011%.
- Colombia’s trade remains sensitive to oil, Fed nerves and local data, with COLCAP and COP both showing caution.
- The ECB rate hike and an oil move of more than 8% keep LatAm FX paths mixed rather than uniformly risk-on.
