A nonperforming asset is a loan or advance on a bank's books where the borrower has stopped making the agreed interest or principal payments. In most countries, a loan is classified as a nonperforming asset once repayment is 90 days or more overdue. At that point, the asset is no longer generating the income the bank expected when it made the loan. It sits on the balance sheet consuming capital without producing a return.
Think of a nonperforming asset as a machine the factory still has to insure and maintain but that stopped producing output.
The 90-day threshold is the most widely used standard, consistent with Basel Committee guidelines and adopted by banking regulators across major economies. A loan crosses into nonperforming status when scheduled principal or interest has not been received for 90 consecutive days.
Once classified, banks apply one of three sub-categories depending on how long the account has been impaired and how likely recovery is.
When a loan becomes nonperforming, the bank stops recognizing interest income on it. Instead, it must set aside capital as a provision, reducing the funds available for new lending. A bank with a 10% nonperforming asset ratio is generating no income on 10% of its loan book while simultaneously holding back capital to absorb potential losses on those same loans.
If the problem becomes severe enough, it threatens solvency. Several Indian public sector banks required government recapitalization between 2017 and 2019 after their nonperforming asset ratios climbed above 10% following a period of aggressive infrastructure and corporate lending that went bad.
Banks have four main tools for dealing with nonperforming assets once identified.
A high nonperforming asset environment in the banking sector affects all borrowers. Banks under provisioning pressure tighten lending standards, raise borrowing costs, and pull back from sectors associated with higher default rates. Credit becomes more expensive and harder to access even for strong borrowers, simply because the banking system has less capital available to deploy.
