In its own words
What could break it.
Regulatory & policy
- U.S.–Mexico tariffs & trade restrictions (border bank — ~32% Mexico-domiciled deposits)medium
As a U.S.–Mexico border bank (Laredo/Brownsville/Zapata), IBC has direct trade-policy exposure: deposits from Mexico-domiciled customers were ~32% of its banks' total deposits in 2025 and its banks actively facilitate cross-border trade finance, so U.S. tariffs and trade restrictions on Mexico could weaken the Mexican economy, cut cross-border trade, lower deposit balances, raise loan defaults and reduce demand for its services.
“We do a significant amount of business for customers domiciled in Mexico, with an emphasis in Northern Mexico. Deposits from persons and entities domiciled in Mexico comprise a large and stable portion of the deposit base of our Subsidiary Banks, and some of our Subsidiary Banks are highly active in facilitating international trade along the United States border with Mexico and elsewhere. The imposition of tariffs and trade restrictions by the United States on Mexico may weaken the Mexican economy, reduce cross-border trade, and ultimately negatively impact the financial wellbeing of our customer base in Mexico.”
