The Cheapest Risk in PolandNarrow moat

PKO Bank Polski (PKO) — moat facet

Thirty basis points of credit cost on a 316 billion złoty book is the closest thing PKO has to a genuine operating advantage.

Every advantage on the other pages was inherited: the branches, the customers, the century of presence. This one PKO produced.

The closest thing PKO has to an advantage a legislature cannot remove: a hundred and six years of learning which Polish borrowers repay.

Cost of credit risk was 0,30% in 2025 and 0,29% in the first half of 20261, improving for a fourth consecutive year2, on a loan book of 315 953 million złoty3. The share of impaired exposures fell to 3,34% from 3,59%4, and has fallen every year since 2021, when it was 3,98%5.

Lending money and getting it back is the entire job of a bank, and the difference between doing it at 30 basis points and doing it at 60 is, on this balance sheet, roughly a billion złoty a year of pre-tax profit. It is the largest controllable variable in the business.

The composition helps. PKO's book is heavily retail and heavily Polish — mortgages, consumer credit and lending to a domestic economy that has grown steadily — and the corporate side is weighted toward large, often state-linked borrowers: the bank handles the budgets of seven voivodeships6 and targets a market share above 20% in financing Poland's energy transition7.

The capital behind the book has grown with it. Own funds went from 42 112 million złoty in 2021 to 50 122 million in 20258, and return on assets — the measure that strips out how much leverage a bank is using — rose from 1,2% to 1,9%9. A bank improving its return on assets rather than only its return on equity is earning more from the lending itself rather than from gearing.

Rated narrow rather than wide, because a credit record is a claim about the past. Thirty basis points was achieved in a benign period for Polish credit, with unemployment low and the economy growing; no Polish bank's underwriting has been tested by a serious domestic recession since 2009.

And the counter-example is in the same accounts. The Swiss franc mortgage book was also underwritten by this bank, was also considered prudent at the time, and has cost 4 365 million złoty in a single year10.

The measure is cost of credit risk against the sector. Holding a gap of 20 or 30 basis points below the average through a downturn would prove the underwriting rather than the environment. Converging on the sector average would mean the last decade was Poland, not PKO.

Moat trajectory: Holding steady

Cost of risk 0,30% in 2025 and 0,29% in the first half of 2026, impaired exposures 3,34% and falling slowly. The record is excellent and it has been excellent for years - there is no improvement left to bank.

The number that tests this moat
Reported
Cost of credit risk
0,30%, and 0,29% in H1 2026

Thirty basis points of annual loss on a 315 953m złoty book. That is the closest thing PKO has to an operating advantage a rival cannot legislate away, and it was earned over a hundred and six years of learning which Polish borrowers repay. Anything above fifty basis points would say the underwriting has slipped or the economy has turned.

Aspects of the moat
DIG DEEPER 01
Thirty Basis Points
Lending 316 billion złoty and losing thirty basis points a year is a hundred and six years of learning who repays.
DIG DEEPER 02
The Impaired Book Keeps Shrinking
3,34 percent impaired and falling, in a market where the sector average is worse.
DIG DEEPER 03
Lending to a Country That Keeps Growing
The credit record was written during three decades in which Poland never had a real recession.
DIG DEEPER 04
Twenty Percent of the Energy Transition
PKO has committed to financing a fifth of Poland's energy transition, which is a strategy target rather than a moat.
⚠ Threats to the moat
⚠ THREAT 01
A Credit Record Is a Claim About the Past
Thirty basis points describes loans already made, not the ones being written now.
⚠ THREAT 02
The Same Bank Underwrote the Swiss Franc Mortgages
The institution with the best credit record in Poland also wrote the worst mortgages in its history.
