Slippage Ratio in Bank Results: How to Read Fresh NPA Formation vs Recoveries

When Indian banks post their numbers, the gross NPA and net NPA ratios grab the headlines. The figure that usually tells you whether those ratios will stay low is the slippage ratio in bank results: how much of the opening standard loan book turned bad during the period. In this guide we define the ratio from official sources, show how it differs from GNPA and NNPA, and walk through reading fresh NPA formation against recoveries, upgrades and write-offs in a typical quarterly presentation.

The system-level percentages here come from the Reserve Bank of India’s Report on Trend and Progress of Banking in India 2024-25 and a February 2026 PIB Lok Sabha reply that quotes RBI data. The asset-classification rules come from the RBI Master Circular on Income Recognition, Asset Classification and Provisioning (IRACP). Read it with our guides on how to analyse quarterly results of a company, provision coverage ratio for banks, and CASA ratio meaning.

What the slippage ratio actually measures

The PIB reply keeps the definition simple: the Slippage Ratio is fresh accretion of NPAs as a percentage of standard advances. The RBI Trends and Progress report says the same thing in supervisory language. For scheduled commercial banks (SCBs), the slippage ratio measures new accretions to NPAs as a share of standard advances at the beginning of the year.

As a formula (the wording banking explainers use, in line with those official definitions):

Slippage ratio (%) = (Fresh slippages during the period ÷ Opening standard advances) × 100

Two things jump out. The denominator is standard advances at the start of the period, meaning the performing book, not total advances and not closing advances. And the numerator is a flow: loans that newly turned NPA during the period. That’s not the same as the stock of NPAs sitting on the balance sheet at period-end.

GNPA tells you how much stress has piled up. Slippage tells you how fast new stress is being created — even when write-offs keep the stock looking calm.

How a loan “slips”: the IRACP path

Under the RBI IRACP Master Circular, a term loan becomes a non-performing asset when interest and/or a principal instalment stays overdue for more than 90 days. Overdraft and cash-credit accounts follow the “out of order” rules in the same circular. Crossing that 90-day line is the moment of slippage in practice.

Before it gets there, lenders have to flag early stress as special mention accounts (SMA):

• SMA-0: principal or interest overdue up to 30 days
• SMA-1: overdue for more than 30 days and up to 60 days
• SMA-2: overdue for more than 60 days and up to 90 days

SMA-2 is usually the pool that feeds next quarter’s slippages. Once an account is an NPA, the circular sorts it by age and recoverability. It is substandard for its first 12 months as an NPA, doubtful once it has stayed substandard for 12 months, and loss when the bank or its auditors find the asset uncollectible but it hasn’t been fully written off.

Provisioning tracks those stages. The circular asks for a general provision of 15% on substandard outstanding, plus an extra 10% (25% in total) on unsecured substandard exposures. Doubtful and loss assets need more, and loss assets need full provisioning. These charges hit the P&L as credit costs. That’s why a jump in slippages in a bank’s results almost always points to higher provisions ahead, unless the book is unusually well secured.

Slippage vs GNPA vs NNPA

It helps to keep the three ratios in separate boxes:

• Gross NPA (GNPA) ratio is the stock of gross NPAs divided by gross advances at a point in time. The RBI Trends report puts the SCB GNPA ratio at a multi-decadal low of 2.2% at end-March 2025 (down from 2.7% at end-March 2024), and at 2.1% at end-September 2025 on supervisory data. The PIB reply, using provisional domestic-operations data, puts SCB GNPA at 2.15% as at end-September 2025, with PSBs at 2.50%, private banks at 1.73% and foreign banks at 0.80% as on 30 September 2025.
• Net NPA (NNPA) ratio is GNPAs minus specific provisions and related items, over net advances. RBI Trends shows SCB NNPA at 0.5% at both end-March 2025 and end-September 2025.
• Slippage ratio is the flow of new NPAs over opening standard advances. RBI Trends says the SCB slippage ratio fell for a fifth straight year to 1.4% at end-March 2025, and again to 1.3% at end-September 2025. The PIB reply has PSB slippage at 0.8% and private-bank slippage at 1.8% in September 2025. So bank groups can drift apart even while the system trend is heading down.

A bank’s GNPA ratio can fall even as it posts high gross slippages, as long as recoveries, upgrades and write-offs remove more stock than fresh formation adds. That’s why a presentation that shows GNPA without a slippage bridge is telling you only half the story.

The NPA bridge: additions, recoveries, upgrades, write-offs

The IRACP circular asks banks to keep MIS that shows opening NPA balances, additions, reductions (upgradations, actual recoveries, write-offs) and closing balances. RBI Trends Table IV.9 lays out that bridge for SCBs in 2024-25 (amounts in ₹ crore):

• Opening GNPAs for 2024-25: ₹4,80,619 crore (slightly different from the prior closing because of an SFB merger noted in the table)
• Addition during the year (fresh accretion, or slippages at system level): ₹2,26,359 crore
• Recovered: ₹67,693 crore
• Upgradations: ₹50,087 crore
• Written-off: ₹1,57,563 crore
• Closing GNPAs: ₹4,31,634 crore

RBI also notes that in 2024-25 around 42.8% of the fall in GNPAs came from recoveries and upgradations. Most of the rest came from write-offs. Write-offs clean up the reported GNPA stock, but they don’t change the fact that those loans slipped in the first place. Upgrades have a higher bar. The IRACP circular lets an NPA go back to standard only when the borrower pays the entire arrears of interest and principal, and for borrowers with several facilities, across all of them.

When you open a single bank’s Q2 investor presentation, look for the same bridge in crore: opening GNPAs, plus slippages, minus upgrades, minus recoveries, minus write-offs or sales, equals closing GNPAs. Then check two things. Does management quote slippage against opening advances or opening standard advances? And is the number quarterly or annualised?

Net slippage (gross slippage minus upgrades and recoveries) is often more informative than gross slippage alone — it shows how much of the fresh formation the bank actually cured in the same period.

How slippage feeds credit cost and PCR

New NPAs force higher specific provisions under IRACP. Credit cost, meaning provisions and write-offs charged to the P&L as a percentage of average advances, tends to move with the slippage mix: secured or unsecured, retail or corporate, and how fast loans age into doubtful. The cushion against NPAs already recognised is the provision coverage ratio (PCR). The IRACP circular defines PCR as provisioning divided by gross NPAs. RBI Trends puts SCB PCR (not adjusted for write-offs) at 76.3% at end-March 2025 and 76.0% at end-September 2025.

If slippages rise, PCR falls and credit cost stays flat, the bank may be under-recognising stress compared with the flow of new NPAs. If slippages rise but PCR stays high and management has already built floating or contingent provisions, the near-term hit to profit can be softer. Read slippage together with the PCR guide linked above. Neither metric means much on its own.

Reading the slippage ratio in bank results: a Q2 checklist

Here’s what we check in a quarterly deck:

1. Find the definition footnote. See whether “slippage ratio” uses opening standard advances (the RBI/PIB approach) or another base such as average advances. Annualise a quarterly ratio only if the bank says it has; multiplying a seasonal quarter by four can mislead.
2. Separate gross from net. Gross slippage is fresh formation. Net slippage takes out upgrades and recoveries from the same period. High gross but low net slippage means the bank is curing accounts fast. The reverse is a warning sign.
3. Break up the book. Retail unsecured, MSME, agri and corporate loans rarely slip at the same pace. A system-wide 1.3% (SCBs at end-September 2025, per RBI Trends) can hide one stressed pocket.
4. Keep an eye on SMA-2 and restructured loans. Today’s rising SMA-2 often becomes tomorrow’s slippage. Restructured standard advances coming out of their monitoring periods can add to formation too.
5. Check funding quality as well. The market tends to talk about asset quality and funding cost in the same breath. After the slippage numbers, look at the bank’s deposit mix with our CASA ratio meaning guide. Weak CASA plus rising slippage squeezes margins harder than either one alone.
6. Compare with the system. In the latest official data, SCB slippage was 1.3% at end-September 2025, with PSBs at 0.8% and private banks at 1.8% in the PIB September 2025 comparison. A private lender above that private-bank figure, or a PSU bank above the PSB figure, needs a closer look at its segments.

The reforms behind today’s low slippage numbers

The PIB reply ties lower GNPA and better PSB slippage to a long list of steps: the 2015 Asset Quality Review, the government’s 4R strategy (recognise, resolve, recapitalise, reform), early-warning systems in public banks (about 80 EWS triggers under the PSB reforms agenda), the Insolvency and Bankruptcy Code, 2016, amendments to SARFAESI and the DRT law, dedicated stressed-asset verticals, and the RBI Prudential Framework for Resolution of Stressed Assets issued on 7 June 2019.

On the IBC, the same reply says that as of March 2025 more than 30,000 applications with underlying default of ₹13.78 lakh crore were settled before admission. DRT pecuniary jurisdiction went up from ₹10 lakh to ₹20 lakh so tribunals could focus on bigger cases. These are facts about reforms, not forecasts. They help explain how system slippage fell for five years in a row to the 1.4% and 1.3% figures in RBI Trends. They don’t promise that every bank’s next quarter will look the same.

Mistakes people make comparing banks

• Mixing up stock and flow. A steady GNPA ratio doesn’t prove fresh formation is low if write-offs are large. SCB write-offs alone were ₹1,57,563 crore in 2024-25, per RBI Table IV.9.
• Using different bases. Opening standard advances, average advances and closing advances won’t give you the same ratio.
• Forgetting seasonality. Agri and retail collections can make one quarter look better or worse than the annual run-rate.
• Assuming upgrades are permanent. An upgraded account can slip again. IRACP’s upgrade rules demand full clearance of arrears, but that says nothing about future cash flows.
• Ignoring the security mix. The same rupee of slippage costs more in provisions if it is unsecured substandard (25% under IRACP) than if it is well secured.
• Judging one bank without the system numbers. Always check the latest RBI Trends or PIB figures before you call a slippage print “high” or “low”.

A worked example (hypothetical numbers)

Say a bank starts the year with ₹1,00,000 crore of standard advances and records fresh slippages of ₹1,400 crore. The slippage ratio is 1,400 ÷ 1,00,000 × 100 = 1.4%. That happens to be in line with the SCB end-March 2025 system figure in RBI Trends, and we use it here only to show the arithmetic. If upgrades and recoveries against those fresh NPAs add up to ₹600 crore in the same year, net formation is ₹800 crore. None of these rupee amounts comes from a real bank’s disclosure. They’re there only to make the formula concrete.

Bringing it into earnings season

For Indian bank results, treat the slippage ratio as the flow partner to the GNPA and NNPA stock ratios and to PCR. Start with the official definition, fresh NPA accretion over opening standard advances. Then read the NPA bridge, segment mix, SMA pipeline and credit-cost outlook side by side. The system data from RBI Trends (SCB slippage 1.4% at end-March 2025 and 1.3% at end-September 2025; GNPA 2.2% / 2.1%; NNPA 0.5%; PCR about 76%) and the PIB reply (PSB slippage 0.8% against 1.8% for private banks in September 2025) are your benchmarks. In each presentation, the job is to work out whether the bank is beating, matching or missing them, and whether the bridge explains why.
