Key Points

• Argentina’s country-risk spread slipped into the mid-500s, from about 625 last week and near 1,050 in mid-October.
• From January 1, 2026, the Central Bank will adjust the peso’s FX band using monthly inflation and run a structured reserve-accumulation plan tied to liquidity.
• The drop revives talk of international borrowing in 2026, even as Argentina remains Latin America’s clear risk outlier.

Argentina’s JPMorgan country-risk spread — a shorthand for the extra interest investors demand to lend the country dollars — moved comfortably below 600 basis points this week and traded around the mid-500s. Investors are reacting to a clearer rule set.

First, the exchange-rate band. Argentina will keep the band, but starting January 1, 2026 the ceiling and floor will adjust each month in line with the latest monthly inflation reading, with a lag, replacing the previous fixed crawl.

Put simply, the official parameters will move closer to the pace of domestic prices, lowering the risk of a large mismatch building quietly.

Second, reserves. The Central Bank said it will deepen its monetary program to accumulate dollars in a way consistent with money demand and daily FX-market liquidity.

Stabilization With Training Wheels

Public descriptions of the mechanism pointed to potential reserve accumulation of roughly $10–$17 billion, with early purchases aligned to about 5% of daily FX-market volume. Reserves matter because they are the buffer that helps a stabilization plan survive shocks.

Markets moved quickly. The wholesale peso traded around 1,449 per dollar, futures improved after a devaluation the previous day, and the S&P Merval index edged higher.

Outside Argentina, the point is that spreads in the 500s are still punishing, but no longer a total lockout. That is why Wall Street desks are discussing a return to international debt markets early next year, and why companies that price off the sovereign curve are watching the policy execution.

Argentina is improving, but it is not “back to normal.” Recent regional spreads put Argentina near 559 basis points versus about 198 for Brazil, 221 for Mexico, 280 for Colombia, 90 for Chile, 124 for Peru, and 62 for Uruguay.
