Argentina's sovereign country-risk index climbed above 800 basis points on Wednesday, pressuring local stocks, bonds and the peso. Traders in Buenos Aires said the slide reflected domestic political tension rather than fresh economic data, even as global markets focused on the US midterm result.

Argentina's sovereign country-risk gauge, which measures the premium investors demand to hold the country's dollar bonds over US Treasuries, pushed past 800 basis points in Wednesday trading in Buenos Aires, its highest level in several months. The move came alongside losses for the Merval stock index and renewed pressure on the peso, as local traders weighed a cluster of domestic political headlines rather than any single piece of economic data.

Market participants pointed to growing friction between President Javier Milei's government and opposition-aligned sectors, including the Catholic Church, as a source of unease heading into the final weeks of the year. Analysts said investors are also parsing how upcoming congressional negotiations and a looming debt calendar could affect the pace of Milei's austerity program, which has underpinned much of the rally in Argentine assets over the past year.

Brokers in Buenos Aires said the sell-off was likely to remain contained unless political tensions escalate further, noting that Argentina's bonds and equities have still posted substantial gains for the year overall. Economists expect the country-risk index to stay volatile in the coming days as traders look past Tuesday's US midterm results toward the government's own policy signals.
