======Non-Performing Loan (NPL)======
A Non-Performing Loan (NPL), sometimes called a bad loan, is a loan that has stopped generating income for the lender because the borrower is significantly behind on payments. Think of it as a deadbeat loan on a bank's books. While the exact definition can vary by jurisdiction, a loan is typically flagged as non-performing when the borrower has missed scheduled payments of [[principal]] or [[interest]] for a continuous period, usually 90 days or more. For a bank, loans are its primary assets—they are supposed to generate a steady stream of income. When a loan stops "performing," it clogs up the bank's [[balance sheet]], earns nothing, and becomes a major headache. A rising tide of NPLs can be a serious red flag, signaling trouble not only for the bank but potentially for the broader economy it serves.
===== Why Should an Investor Care? =====
For investors, especially those following the principles of [[value investing]], NPLs are far more than just boring bank-speak. They are a critical health metric for any financial institution and offer a window into its risk management, lending quality, and future profitability. Ignoring NPLs when analyzing a bank is like buying a used car without checking under the hood—you might be in for a nasty surprise. Tracking a bank's NPL trend allows you to assess risk, spot potential turnarounds, and make more informed decisions about whether a bank's stock is a bargain or a trap.
==== The Canary in the Coal Mine: NPLs and Bank Health ====
The simplest way to gauge a bank's exposure to bad loans is by looking at its [[NPL Ratio]]. This is a straightforward calculation:
//NPL Ratio = Total Value of Non-Performing Loans / Total Value of All Outstanding Loans//
A rising NPL ratio is a classic warning sign of deteriorating [[asset quality]]. When this happens, a bank is forced to take two painful actions:
  * It must increase its [[loan loss provisions]], which means setting aside more money to cover expected losses from these bad loans. This directly eats into the bank's profits and can hammer its [[earnings per share (EPS)]].
  * It will likely tighten its lending standards to prevent the problem from getting worse. While prudent, this can choke off loan growth and dampen future revenue.
Ultimately, a high and rising NPL ratio shrinks a bank's [[net interest margin]]—the core driver of its profitability—and, in severe cases, can even call its solvency into question.
==== The Value Investor's Angle on 'Bad' Loans ====
While NPLs signal risk, they can also spell opportunity for the patient and discerning investor. The market often panics at the first sign of rising NPLs, punishing a bank's stock price excessively. This is where a value investor can find an edge.
=== Opportunity in Pessimism ===
When a bank's stock is beaten down due to bad loan fears, it might be a classic turnaround opportunity. The key is to dig deeper. Is the management team competent and transparent about the problem? Does the bank have a credible plan to clean up its balance sheet? Is it sufficiently capitalized to withstand the losses? If you conclude that the market has overreacted and the bank is trading for less than its intrinsic worth, you could be looking at a bargain. The goal is to buy when pessimism is at its peak, just as the bank is beginning to resolve its issues.
=== The NPL Ecosystem ===
Another fascinating angle is to invest in the "cleanup crew." This refers to specialized firms, often in the world of [[private equity]] or [[distressed debt investing]], that buy huge portfolios of NPLs from banks at a steep discount—sometimes for pennies on the dollar. Their entire business model revolves around working out these bad loans, either by restructuring the debt with the original borrower or by seizing and selling the underlying collateral. Investing in one of these publicly-traded specialty finance companies can be a clever way to profit from the NPL cycle without taking on the direct risk of a traditional bank.
==== How to Spot NPLs in the Wild ====
You don't need to be a forensic accountant to find a bank's NPL data. This information is publicly available in a bank's regular financial filings.
  * For US-based banks, check the [[10-K]] ([[annual report]]) and 10-Q (quarterly report). Look for sections titled "Credit Risk," "Asset Quality," or "Allowance for Credit Losses."
  * For European banks, this data is found in their Annual and Interim Reports, typically within the "Risk Management" chapter.
When you find the data, look for these key indicators:
  * **The NPL Ratio Trend:** Is the ratio rising, falling, or stable? A consistent upward trend is a major warning. Compare the ratio to the bank's closest competitors to see if the problem is industry-wide or specific to that bank.
  * **Coverage Ratio:** This tells you how much money the bank has already set aside in provisions to cover its NPLs. A high coverage ratio (e.g., over 50%) is a sign of prudence, as it shows the bank is well-prepared to absorb the inevitable losses from its bad loans.
