Banco Nación raises mortgage loan rates

Banco Nación has raised the nominal annual interest rate on its UVA mortgage line from 6% to 6.7%. This adjustment is particularly noteworthy as Banco Nación holds a leading position in Argentina's mortgage market following the relaunch of housing credit.

The revised rate applies to the acquisition of a primary residence for individuals whose salaries are managed through the bank. This change reshapes the landscape of competitive mortgage offerings. Currently, Banco Nación, BBVA, and Banco Ciudad are among the entities with initial monthly payments ranging from approximately $97,000 to $111,000 for every US$10,000 borrowed, though the final amount depends on the rate, term, and specific loan conditions.

This decision follows a trend where 12 banks had previously lowered their mortgage rates in the first five months of 2026, aiming to stimulate demand that had weakened in the latter half of 2025 due to rising financing costs. Despite the rate increase, Banco Nación continues to offer the most competitive rate nationwide for its mortgage products.

The underlying reason for Banco Nación's rate adjustment appears to be its increased funding costs. In July, the bank issued a new series of debt securities adjusted by UVA at a rate of UVA + 6.5%. This issuance, part of a larger US$270 million offering to fund private sector financing, contrasts with an earlier issuance on May 7th, where UVA debt for mortgage credits was issued at UVA + 5.25%. The cost of this funding rose by 1.25 percentage points in just two months.

Economists suggest this move is directly linked to the higher cost of debt issuance. "The BNA's debt issuance a few weeks ago, with a rate above 6%, must have been the trigger for this. I imagine it's along those lines, because they issued debt at a higher rate than 6%, so they cannot lend at less, unless they cover the difference," explained Federico González Rouco, an economist specializing in housing, to LA NACION. The fundamental principle is that for a sustainable mortgage system, banks require long-term funding at a cost that allows for profitable lending. When funding costs rise, maintaining lower mortgage rates forces the bank to absorb the difference, a significant challenge for the market.
