Most Lending Books Don’t Break Suddenly — They Loosen First

Nobody sends an email to say the book is loosening. There is no formal meeting, no board resolution, no policy change. The loosening happens in the white space between decisions like one approved exception, one negotiated flexibility, and one adjacent segment noted as underserved.

Each accommodation is defensible. Each has a commercial rationale. And each moves the book in a direction the current portfolio cannot yet reflect, because loans written under new implicit standards have not had time to reveal themselves.

Over time, constraints such as ticket limits, tenure caps, and restricted borrower profiles can start to feel overly cautious. Loosening them may appear measured and commercially sensible, but the resulting shift in portfolio quality often takes more than a year to become visible.

 How Growth Becomes the Enemy of the Book

There is a natural operator instinct to remove constraints as a business scales. Constraints feel like early-stage caution: the scaffolding you put up when you are not yet confident, which you take down once the business has proven itself. The logic seems sound: if the book is performing, expand the parameters. If the underwriting has worked at ₹50,000 tickets, it should work at ₹2,00,000. If 90-day loans are performing well, 180-day loans should not be materially different.

This instinct is how lending books quietly accumulates the risk that the next downturn exposes.

The performance of the constrained book was not incidental to the constraints. It was produced by them.

• Small tickets meant that no single default could impair the portfolio.
• Short tenure meant the book was always close to the moment of underwriting, when the information was still good.
• A restricted borrower profile meant selection was happening at the source, not from a thin file assembled by a borrower motivated to present themselves well.

Remove the constraints, and you do not simply scale the business. You change the risk architecture of the book, one loosening at a time, in ways that the current portfolio performance cannot yet reflect.

The P&L looks fine while this is happening. It always does. The cost accumulates in the parts of the book that have not yet been tested.

 One Defensible Decision at a Time

It rarely arrives as a single decision to abandon discipline. It arrives as a series of small accommodations, each reasonable in isolation.

●      The Borrower Just Outside the Profile

A borrower profile slightly outside the defined segment, but with a strong bureau score. The relationship manager makes the case. The credit committee approves the exception. A note is added to the file. Nothing formal changes.

●      The Ticket Above the Limit

A ticket size above the stated limit, for a relationship that brings volume. The commercial logic is sound. The underwriting looks clean. The exception is approved with a slightly higher interest rate to compensate for the additional risk. It feels like judgment, not loosening.

●      The Tenure Extension That Becomes an Expectation

A tenure extension on a loan that is performing, to help a borrower through a cash flow gap. Reasonable. Compassionate, even. But the borrower tells others. The next borrower asks for the same. The exception becomes a reference point.

None of these feels like policy changes. They feel like judgment calls, exercised sensibly by people who understand the portfolio. The problem is that judgment calls compound. Each accommodation sets a new implicit reference point for the next one. By the time the book has moved materially from the original constraint framework, the individual decisions that produced the movement were all defensible. The aggregate was not.

I watched this happen, and I participated in it. The loosening felt like maturity. It was disguised as confidence. What it actually was, I understood later, was a gradual reduction in the specificity of what we had set out to build.

 The Cohort That Asked the Question

The recognition did not come from a crisis. It came from a conversation with a senior credit officer who pointed at an older cohort and asked why the profile looked different from the cohorts before and after it.

The answer was that we had been in a growth phase. We had expanded ticket sizes to capture a larger market. We had relaxed the borrower profile to serve a segment that was adjacent but not identical to our core. We had extended tenures on a category of loans where the business case seemed strong.

The cohort was now showing early stress. Not catastrophically. But measurably, and in the direction you would expect if the constraints that had produced the earlier performance were no longer operating with the same rigour.

The constraints had not been formally removed. They had simply been exercised with less precision. That was enough.

The Constraint is the Business

What I came to understand, through that conversation and the months that followed, is that the constraints are not the scaffolding. They are the structure.

Small tickets, short tenure, controlled use of funds, selection at source — these are not limitations imposed on a lending business while it is finding its feet. They are the mechanisms that define what kind of lending business it is. A book built on them performs differently through a cycle from one that adopted them loosely and then loosened them further under commercial pressure. The difference becomes structural during a downturn.

The strongest operators in any capital business understand this. They treat self-imposed constraints not as a cost of discipline but as a source of competitive advantage. The constraint that prevents a lender from chasing a larger ticket size is the same constraint that protects the book when that segment deteriorates. The tenure limit that feels conservative in an expansion is the limit that keeps the lender close to reliable information when conditions change.

Removing a constraint to capture an opportunity is sometimes the right decision. It should never feel easy. The ease with which constraints are removed is usually a sign that the discipline that produced them was never fully internalised, but only practiced while conditions made it painless.

 What the Constraint Actually Protects

The best businesses are built on constraints, not freedom. The constraint is not protecting the lender from risk. It is protecting the lender from themselves and from the entirely rational, commercially justifiable, relationship-driven impulse to make one more exception. Lending discipline is a quality of structure. The operator who relies on their own judgment to hold the line will eventually find the line has moved. The one who builds the constraint into the architecture of the book does not have to rely on judgment at all. The structure holds it. That is the only form of discipline that survives a growth phase intact — and the only form worth building around.
