Argentina's consumer price index for October showed inflation between 1.6% and 1.8%. Mexico's economy expanded in the third quarter at a rate between 3.0% and 3.5%. Colombia's Central Bank decided to leave its monetary policy stance unchanged in its October meeting.

The reported range of 1.6% to 1.8% represented the institute's estimate for the month. The release formed part of the regular inflation report cycle.

Mexico's third-quarter gross domestic product growth figure was published on Friday, 30 October. The estimate placed expansion between 3.0% and 3.5%. The data were issued by the national statistics agency as the latest quarterly performance indicator.

Colombia's Central Bank announced its policy decision on Friday, 30 October. The board chose to keep the benchmark interest rate at its current level, opting against any adjustment. The decision followed the Bank's review of recent inflation and growth trends.

## Analysis

The drop in Argentina's monthly inflation to a range of 1.6%-1.8% suggests a cooling of price pressures after a period of higher increases. A lower inflation rate can reduce the urgency for the Central Bank to tighten monetary policy, potentially keeping borrowing costs stable. However, the sustainability of this slowdown remains uncertain, as future data could reveal a reversal.

Mexico's third-quarter growth of 3.0%-3.5% indicates a solid expansion pace for the economy, supporting fiscal revenue and private investment expectations. Such a performance may reinforce confidence among investors and policymakers about the country's economic trajectory. Yet, the outlook depends on external factors such as commodity prices and global demand, which could affect subsequent quarters.

The Central Bank may still adjust its stance if inflation deviates from targets or if economic conditions shift unexpectedly.
