Overview

Colombia’s heterogeneity analysis treats institutions holding more than 10 percent of consumer credit as large; three of 31 sample institutions consistently met that threshold. Above 108 months, smaller lenders reduced originated loan amounts by approximately 20.9 percent in the strict matched estimate and LTV by about 8.8 percentage points. The effects are distributional, not proof of rejected applications or a universal weakness of smaller institutions; at 72 months, their effects were not robust.

Learning outcomes

Above 108 months, smaller lenders reduced originated loan amounts by approximately 20.9 percent in the strict matched estimate.
They also reduced LTV by about 8.8 percentage points; this concerns collateralized originated loans, not all consumer credit.
The effect was not robust at the 72-month threshold, and large lenders’ offsetting loan-amount component did not establish a significant total expansion.

The Uneven Tightening Hidden in the Average

The aggregate estimates leave an important question unanswered: if the maturity-specific rule raised the cost of long loans but did not change average rates, amounts, or LTV, who absorbed that cost? The study answers by comparing lenders with different positions in Colombia’s consumer-credit market. The result is an absorb-versus-retrench pattern: larger institutions show no significant total adjustment, while smaller institutions tighten the longest loans through principal and collateral. This chapter explains what that pattern supports—and what it still cannot prove about borrower access.

Market position changes the same cost

The study divides institutions according to their market share in consumer credit. It labels an institution “large” when it holds more than 10 percent of the total consumer-credit portfolio in the relevant quarter. Of the 31 institutions in the sample, three consistently meet that threshold. The remaining institutions are treated as smaller for the heterogeneity analysis.

This is a useful distinction, but it is not a complete balance-sheet diagnosis. Market share can signal scale and a stronger ability to spread a provisioning cost across a broad portfolio. It may also be associated with funding access, product diversification, pricing power, capital buffers, or a different risk-management model. The study does not identify which of those features causes the response. It uses market position as an observable way to test whether the same regulatory shock affects institutions differently.

That qualification matters because “large” is not synonymous with “safe,” and “small” is not synonymous with “weak.” A smaller lender may have a profitable niche or superior information about a particular borrower group. A large lender may also have concentrated exposures or its own constraints. The evidence supports a difference in estimated responses by market position; it does not rank institutions or establish a universal rule about their financial health.

The economic logic behind the comparison is nevertheless clear. The maturity-specific factor applies to the loan, but the cost is borne first by the institution’s balance sheet. A lender with greater scale may be able to absorb a modest additional provision without changing the contract. A lender with fewer ways to diversify may protect its margin or capital by reducing exposure to the maturity tier where the additional factor is highest. The same regulation can therefore create a common pressure and different local decisions.

This is an interface between regulation and market structure. The regulator sets one maturity rule; each institution translates it through its own portfolio and operating constraints; the borrower encounters the result as a contract or an unavailable option. A market-share threshold is useful because it makes that interface observable, but it does not reveal every step inside the institution. The evidence can show that responses differ by the proxy for market position without identifying whether scale, capital, funding, margins, or risk models carry the difference.

The heterogeneity analysis keeps the main contract outcomes separate.

FAQ

What happened to smaller lenders’ loans above 108 months?

In strict matched estimates, smaller lenders reduced originated loan amounts by approximately 20.9 percent and LTV by about 8.8 percentage points above 108 months.

Does a lower LTV mean the lender required more collateral?

It means the loan amount was lower relative to collateral value, leaving more collateral or borrower equity beneath the loan; the LTV sample includes only nonzero collateral.

How did the study define a large institution?

It classified an institution as large when it held more than 10 percent of total consumer-credit portfolio in the relevant quarter; three of 31 sample institutions consistently met that threshold.
