The Charter and the Capital RatioWide moat

PKO Bank Polski (PKO) — moat facet

A 17,10 percent total capital ratio is a wall against entrants and a cap on returns at the same time.

Twenty-nine banks operate in Poland1, and the number is set by a supervisor rather than by a market.

Capital, not earnings, is what a supervisor rations. The buffer above requirement is what allowed a 75% payout - and what a single decision could close.

That is the foundation of every bank moat, and it is worth being precise about what it protects. It does not stop competition — PKO competes hard for every deposit against Pekao, Erste Bank Polska, mBank and ING — but it stops the kind of competition that destroys industries, where a well-funded outsider decides to buy market share at a loss. A newcomer needs a licence, capital, and a supervisor's confidence.

The capital itself is the second barrier and PKO carries it comfortably: a total capital ratio of 17,10% at the end of 2025 and common equity tier 1 of 15,55% at mid-20262, against own funds of 50 122 million złoty3.

Those ratios are also what permits the dividend. PKO paid out 75% of the 2025 profit4, which a bank close to its requirement could not do.

The ratio fell in 2025, from 19,04% to 17,10%5, as the balance sheet grew faster than capital — the ordinary consequence of lending 13,9% more.

The five-year record shows how stable it has been through genuine stress: total capital ratios of 18,73%, 19,07%, 18,84%, 19,04% and 17,10%6 across a period containing the credit holidays, the worst of the Swiss franc litigation and a 39% increase in the balance sheet.

Grade this on the ratio against the requirement. Seventeen percent is comfortable; the direction of travel matters more than the level, because capital is what converts a licence from a permission into a franchise.

Moat trajectory: Holding steady

17,10% total capital against a requirement that has not moved much. The barrier is intact and so is the cap on returns.

15,55% at 30 June 2026

The buffer above requirement is what a bank can actually deploy or distribute. PKO's is wide, which is why the payout was permitted. A supervisory decision - not a market event - is what would close it.

Capital Requirements Rise When Nobody Wants Them To
Buffers are set by supervisors, and supervisors raise them in exactly the years a bank would rather they did not.
