Buying debt portfolios: how the funds invest

What a debt portfolio is

A debt portfolio (or NPL portfolio) is a package of unpaid loans that a bank bundles to sell in bulk to a single buyer. The bank does not sell each loan separately: it packages them into lots by type (mortgages, consumer loans, business loans), geography or age of default, and offers them in competitive processes to investment funds.

The size of these portfolios can be enormous. In Spain, after the 2008 financial crisis and in the years that followed, banks sold portfolios worth billions of euros in NPLs to specialised funds. Today the portfolio market is more mature but still active: business arrears and the legacy of prior credit excess continue to generate NPLs that banks want off their balance sheets.

Who buys debt portfolios

Portfolio buyers are almost always specialised distressed-asset or NPL funds. These funds have legal teams, portfolio managers and agreements with servicers (debt management companies) to manage the collection of thousands of loans simultaneously.

The largest funds operate at European or global scale: Cerberus, Lone Star, Blackstone, Apollo, Bain Capital Credit and doValue are familiar names in major Spanish transactions. There are also smaller domestic funds specialising in portfolios of more modest size.

How an NPL portfolio is valued

Valuing a portfolio is complex because you have to estimate how much can be recovered from each loan and in what timeframe. Buyers run a due diligence process that includes reviewing each loan file, the collateral, the judicial status of each position and recovery probabilities.

• Gross Book Value (GBV): the total face value of the portfolio's loans, i.e. what is owed on paper.
• Net Book Value (NBV): the bank's book value after provisions.
• Purchase price: what the fund pays, usually expressed as a percentage of GBV. A mortgage portfolio may be negotiated at 35%-60% of GBV depending on collateral quality.
• Expected internal rate of return (IRR): what the fund expects to earn from the portfolio, net of management and recovery costs.

The role of the servicer

The servicer is the company that manages collection of the portfolio on behalf of the fund. It contacts borrowers, negotiates settlements, processes enforcement proceedings and manages awarded properties. In Spain the main servicers are Anticipa (Blackstone), Altamira (doValue), Solvia (now part of Intrum) and Haya Real Estate.

The servicer earns a fee on managed volume or on recoveries. Its efficiency largely determines the fund's final return on the portfolio.

Why you cannot buy a whole portfolio yourself

NPL portfolios are sold through competitive processes (data rooms, NDAs, binding offers) and banks only accept bids from buyers who can demonstrate financial capacity and management infrastructure. The minimum portfolio size is usually tens of millions of euros, and the bank wants to ensure the buyer has the resources and infrastructure to manage it.

For the private investor, the route is not the portfolio but the individual deals that flow from it: auctions, remate assignments and adjudications. That is where they can compete with limited resources.

Portfolio market trends in Spain

The NPL portfolio market in Spain remains one of the most active in Europe, though smaller than at the crisis peak. Post-pandemic business arrears and tensions in the commercial property market continue to generate new portfolio flow. Fintech lenders and some family offices are starting to access smaller portfolios (micro-portfolios), opening the market to investors with less capital.
