What the Licence Is Worth, and What It CostsNarrow moat

PKO Bank Polski (PKO) — moat facet

The charter keeps competitors out and hands the state a lever it has now pulled three times in a decade.

Most of what protects a bank was granted rather than built, and PKO's position is the clearest example of that in this collection.

Three of the four things protecting this bank were granted by the state. The state has just demonstrated what granting implies.

A banking licence keeps the field to 29 institutions1 rather than to anyone with capital and an idea. Capital requirements, liquidity rules and supervision by the Polish Financial Supervision Authority make entry expensive and make an existing balance sheet valuable. PKO carries a total capital ratio of 17,10%2 and common equity tier 1 of 15,55% at mid-20263 — comfortably above requirement, which is what allows it to pay out 75% of profit as a dividend4.

The same authority that keeps rivals out also decides what PKO may keep. Three separate mechanisms take a share before shareholders see anything.

The first is the tax on certain financial institutions — a levy on assets rather than profits, which took 1 349 million złoty in 20255 and is owed whether or not the bank earns anything. The second is the ordinary corporate income tax, which for commercial banks rose from 19% to 30% on 1 January 2026, falling to 26% in 2027 and 23% in 20286. The third is the supervisor's discretion over dividends, which is why the payout ratio is a number PKO proposes and the regulator permits.

The arithmetic of the second arrived in the first half of 2026 and is worth stating plainly: profit before tax rose 19,9% to 8 319 million złoty, the tax charge rose 67,4% to 3 029 million, and net profit rose 3,1%7.

The capital that makes the licence worth holding has been rebuilt rather than assumed. Own funds rose from 42 112 million złoty in 2021 to 50 122 million in 20258 — through the credit holidays, the Swiss franc provisions and a 39% larger balance sheet — which is why the bank can now distribute three-quarters of its profit rather than retaining it against a legal liability.

Rated narrow. The protection is genuine and durable — nobody is going to be granted a Polish banking licence and a branch network — and it is a protection the state can reprice at will, and did.

The measure is the effective tax rate. It steps down to 26% in 2027 and 23% in 2028 under the current law9. Whether those steps actually happen is the single largest swing factor in PKO's earnings that has nothing to do with banking.

Moat trajectory: Narrowing

The charter still keeps entrants out, but the price of holding it rose in November 2025 when the tax rate on commercial banks went from 19% to 30%. The wall is unchanged and the toll is higher.

The number that tests this moat
Reported
Total capital ratio
17,10%, against own funds of 50 122m zł

The charter keeps twenty-nine banks in and everyone else out, and the price is a capital base that cannot be levered the way an unregulated lender's can. The 17,10% is comfortably above requirement, which is what allows a 75% dividend. Watch the ratio rather than the profit: capital, not earnings, is what the supervisor rations.

Aspects of the moat
DIG DEEPER 01

DIG DEEPER 02
A Levy on Assets, Owed Whether or Not You Earn
1,35 billion złoty a year on assets rather than profit — a quarter of the entire fee income, charged for existing.
DIG DEEPER 03
The Dividend the Regulator Permits
PKO paid out 75 percent of the 2025 profit because the supervisor allowed 75 percent.
DIG DEEPER 04
The Shareholder Who Writes the Rules
The State Treasury holds 29,43 percent of the bank and one hundred percent of the tax code.
⚠ Threats to the moat
⚠ THREAT 01
The Rules Can Be Changed by the Largest Shareholder
In November 2025 the owner raised its own bank's tax rate by eleven points and gave four weeks' notice.
⚠ THREAT 02
A Mortgage Written in 2008 Still Costs Four Billion a Year
4 365 million złoty of Swiss franc legal risk in 2025 — forty percent of net profit, on loans stopped fifteen years ago.
