Montana Banks: Highest Multifamily Delinquency

Definition and formula

The multifamily noncurrent rate is the share of a bank's multifamily loans, mortgages on apartment buildings with five or more units, that are on nonaccrual or 90 or more days past due and still accruing.

Multifamily noncurrent rate = (Multifamily loans on nonaccrual + Multifamily loans 90+ days past due and still accruing) / Multifamily loans

Which banks are ranked

This list ranks the 7 banks headquartered in Montana that meet every rule below, using each bank's latest FFIEC call report (data as of September 30, 2026).

• Banks with at least $100M in total assets, so a ratio on a very small balance sheet cannot lead the list.
• Banks with at least $25M in multifamily loans, so a rate on a few loans cannot lead the list.
• Lending institutions only: charters with loans under 5% of assets, mostly trust and custody banks, are not ranked.
• Charters the regulator has closed, merged or converted are excluded.
• Each bank charter ranks on its own; holding companies are not combined.

What moves the multifamily noncurrent rate

The rate rises when apartment owners cannot cover their debt service, most often when a loan written at a low fixed rate comes up for refinancing at a higher one, or when rent limits or new supply hold rents below rising costs. It falls as the bank restructures, sells or charges off problem loans. Most banks report no noncurrent multifamily loans at all, so a single large building can put a bank near the top of this list; read the rate beside the dollar amounts on the bank's asset quality page.
