For a bank credit analyst building a watch list, past-due loans answer a practical question: is borrower stress showing up before nonaccrual loans make the problem obvious?
Who this is for: Bank analysts are the primary reader, but the same read can help fintech founders reviewing sponsor banks, financial journalists comparing peer credit trends, and small-bank board members reviewing management.

Answer First: Past-Due Loans Can Move Before Nonaccrual
The short version is this: 30-89 days past due loans can rise before nonaccrual loans because Call Report RC-N separates delinquency from nonaccrual status. A loan can be late, still accruing, and not yet in the nonaccrual column.
The practical test is to compare the past-due category in RC-N with the matching loan balance in RC-C, then check whether charge-offs in RI-B and allowances in RI-C are moving in the same direction. If past due rises while nonaccrual, charge-offs, and reserves stay flat, the right response is not comfort. It is follow-up.
The best starting point is FFIEC Central Data Repository public Call Report data,[1] especially Schedule RC-N, “Past Due and Nonaccrual Loans, Leases, and Other Assets.” The FDIC’s March 2026 Call Report materials page lists FFIEC 031, 041, and 051 forms for the March 31, 2026 report date, with the FFIEC 031/041 and FFIEC 051 instructions most recently updated December 31, 2025.[2]
Past-due loans can provide an earlier view of credit stress than nonaccrual loans because RC-N separates loans that are still accruing but already late from loans in nonaccrual status. A borrower can miss payments, appear in the 30-89 day past-due bucket, and still not be in the nonaccrual column. That gap is where early credit work happens.
Past-Due Loans vs Nonaccrual Loans In RC-N
Schedule RC-N instructions for FFIEC 051[3] say banks report the balance sheet amount of loans, leases, securities, and other assets that are past due or in nonaccrual status, not just the missed payment amount, and they report those amounts without deducting the allowance for credit losses. That matters because a single missed payment on a large commercial real estate loan can move the whole loan balance into a past-due column.
RC-N columns are mutually exclusive. Column A covers assets 30 through 89 days past due and still accruing. Column B covers assets 90 days or more past due and still accruing. Column C covers nonaccrual assets. If Column A rises in a loan category while Column C is flat, the bank may still be before the stage that shows up in headline nonaccrual numbers.
The RC-N instructions also define past due by contract type. Monthly installment loans are generally past due when the borrower is in arrears two or more monthly payments, though a bank may choose to report monthly loans past due when one scheduled payment is due and unpaid for 30 days or more. Open-end credit, including credit cards, is past due when the customer has not made the minimum payment for two or more billing cycles.
A useful first test is not “did nonaccrual spike?” It is “did RC-N Column A rise in a category that is large enough in Schedule RC-C to affect the bank?” A 30-89 day move in construction, nonfarm nonresidential real estate, credit card, auto, or commercial loans deserves different weight depending on the bank’s loan mix.
A Simple Early-Warning Example
| Quarter | RC-C loan category balance | RC-N Column A: 30-89 days past due | Column A ratio | RC-N Column C: nonaccrual |
|---|---|---|---|---|
| Q1 | $500 million | $2.5 million | 0.50% | $4.0 million |
| Q2 | $510 million | $4.1 million | 0.80% | $4.1 million |
| Q3 | $515 million | $7.7 million | 1.50% | $4.2 million |
| Q4 | $520 million | $10.4 million | 2.00% | $4.3 million |
In this simplified example, nonaccrual barely moves from $4.0 million to $4.3 million, but the 30-89 day past-due ratio rises from 0.50 percent to 2.00 percent. That is the early warning. The next question is whether those loans cure, roll into 90-day delinquency, become nonaccrual, or require higher charge-offs and allowances.
Nonaccrual Is A Different Stage
Nonaccrual status is not just a longer version of past due. The RC-N instructions say an asset is reported as nonaccrual if it is maintained on a cash basis because of deterioration in the borrower’s financial condition, if payment in full of principal or interest is not expected, or if principal or interest has been in default for 90 days or more unless the asset is both well secured and in the process of collection.
That 90-day rule creates a real lag. A loan can move from current to 30-89 days past due, then to 90 days or more past due and still accruing, and only then to nonaccrual if the bank’s collectability assessment requires it. Consumer and 1-4 family residential loans also have specific reporting treatment in the instructions, so the same delinquency age may not tell the same story across portfolios.
The FDIC’s Fourth Quarter 2025 Quarterly Banking Profile statement[4] used “past-due and nonaccrual,” or PDNA, to describe loans 30 or more days past due or on nonaccrual status. The FDIC reported an overall industry PDNA rate of 1.56 percent in fourth quarter 2025, below the 1.94 percent pre-pandemic average for first quarter 2015 through fourth quarter 2019, while also saying weakness persisted in certain portfolios.
That portfolio detail is the point. In the same Q4 2025 statement, the FDIC reported that banks with more than $250 billion in assets had a non-owner-occupied commercial real estate PDNA rate of 4.06 percent, below the recent 4.99 percent peak in third quarter 2024 but well above the 0.58 percent pre-pandemic average. A bank can look fine at the all-loan level and still have a credit story inside one loan book.
- Compare RC-N Column A with Column B and Column C in the same loan category, not just total loans.
- Use charge-offs and recoveries to see whether delinquency is turning into realized loss.
- Use allowances and provision expense to test whether reserves are moving with the credit trend under expected credit loss accounting.
Expected credit loss accounting is another reason past-due data matters before nonaccrual spikes. FASB Accounting Standards Update No. 2016-13, Financial Instruments-Credit Losses (Topic 326),[5] issued in June 2016, moved credit-loss accounting toward expected credit losses. A reserve process that waits for nonaccrual alone is late by design.
Watch Mix And Seasoning
Rapid loan growth can hide credit deterioration by expanding the denominator in a past-due ratio. Use quarter-end loan balances, then ask whether growth in new originations is masking stress in older vintages. Call Reports do not give a full vintage table for every bank, so mix and growth have to be part of the read.
Commercial real estate needs special care because concentration can turn a modest delinquency move into a board-level issue. The December 2006 Interagency CRE Concentration Guidance[6] says regulators may identify an institution for further supervisory analysis when construction, land development, and other land loans equal 100 percent or more of total capital, or when total commercial real estate loans equal 300 percent or more of total capital and the portfolio has grown 50 percent or more during the prior 36 months.
Those CRE figures are supervisory screening criteria, not automatic failure lines. They are still useful because they force the right pairing: RC-N delinquency by category next to loan exposure and capital. A small uptick in past due construction loans means more when construction loans are already large relative to total capital.
After the past-due signal is visible, secondary checks can sharpen the read. Funding mix, public enforcement history, sponsor-bank controls, and third-party risk do not replace the credit analysis, but they can explain whether a rising delinquency trend is isolated, manageable, or part of a broader risk-management problem.
Use Past Due Data For Questions
Use this five-step workflow before clearing a bank just because nonaccrual loans have not moved yet.
- Confirm the institution in FDIC BankFind[7] or the FFIEC National Information Center[8]. Output: one correct bank name, certificate or RSSD identifier, regulator, and Call Report series.
- Pull RC-N Column A, Column B, and Column C for the loan categories that matter. Output: a four-quarter trend for each category, with Column A isolated from total past-due and nonaccrual totals.
- Calculate the category-level ratio. Output:
RC-N Column A for the category / RC-C balance for the same category, compared quarter over quarter and year over year. - Check loss confirmation. Output: the same-period trend in net charge-offs, allowances, and provision expense; a rise in past due without any reserve or provision response should trigger follow-up.
- Decide whether the move is meaningful. Output: a short question list for management when the category ratio rises materially from its own history, rises faster than peers, moves across more than one quarter, or appears in a concentrated loan book.
| Pattern | What to ask next | Why it matters |
|---|---|---|
| RC-N 30-89 days past due rises, nonaccrual is flat | Which borrowers, vintages, geographies, or loan officers explain the movement? | Early delinquency may be building before the bank changes accrual status. |
| RC-N 90 days or more past due and still accruing rises | Which credits are well secured and in the process of collection? | The RC-N nonaccrual test depends on collectability, not only payment age. |
| Past due rises while charge-offs stay low | Are extensions, renewals, collateral values, or collections delaying loss recognition? | Charge-offs can lag delinquency, especially in secured portfolios. |
| Past due rises while allowances and provision expense stay flat | What changed in the expected-loss assumptions, qualitative factors, or portfolio segmentation? | Expected-loss reserves should respond to changing credit quality, not only confirmed losses. |
Public enforcement pages are part of the same secondary check. Search the FDIC enforcement decisions and orders database,[9] the OCC enforcement actions page,[10] and the Federal Reserve enforcement actions database[11] for the bank and its holding company. If an order names credit administration, loan review, liquidity risk, concentration risk, BSA/AML, or third-party oversight, read the RC-N trend with that order in mind.
For fintech founders, this credit read is not a substitute for sponsor-bank operational diligence. The June 2023 Interagency Guidance on Third-Party Relationships: Risk Management[12] says a bank’s use of third parties does not remove its responsibility to operate safely and comply with law. A sponsor bank can have clean credit numbers and still have third-party risk issues, and the reverse can also be true.
The decision rule is simple: do not wait for nonaccrual to confirm a credit story that RC-N is already showing. If past-due balances are rising in a large or concentrated portfolio, tie the trend to loan mix, charge-offs, provisions, allowances, capital, funding, and any public orders before making a sponsor-bank, investment, board, or reporting judgment.

FAQ
How do I calculate the past-due loan ratio for one category?
Use the matching loan category in the denominator. If nonfarm nonresidential real estate has $6 million in RC-N Column A and $600 million in the same RC-C loan category, the 30-89 day past-due ratio is 1.00 percent. Do the same calculation for Column B and Column C so delinquency and nonaccrual are not blended together.
When can 90+ days past due and still accruing happen?
It can happen when the loan is 90 days or more past due but the bank still treats it as accruing, commonly because the asset is well secured and in the process of collection. That does not make the loan harmless. It means the credit needs a collectability and collateral review, not just an age bucket review.
What counts as a meaningful move worth investigating?
A move is meaningful when it is large relative to the bank’s own history, appears for more than one quarter, rises faster than similar peers, or occurs inside a concentrated portfolio. A 25 basis point change in a small, diversified book may be noise. The same change in a large construction book at a thinly capitalized bank deserves a management question.
Should I compare past-due loans to total loans or category loans?
Start with category loans. Total-loan ratios are useful for a high-level scan, but they can hide stress inside CRE, commercial, auto, credit card, or construction books. The category-level ratio is usually the faster way to see whether a specific loan book is changing.
What is the fastest peer check?
Compare the same RC-N category as a share of the same RC-C loan category across similar banks, then compare charge-offs and allowances. For workflow inside this site, use the Banking peer comparison view after you identify the relevant RC-N category, and keep the peer set close on loan mix, asset size, geography, and growth rate.
