Whose banks are these, exactly?

The Polish economic miracle story rests implicitly on the assumption of a functional, sovereign financial system - a banking sector that intermediates domestic savings, allocates credit to Polish businesses and behaves, in moments of stress, in the interests of the Polish economy. That assumption is largely fiction. Polish banking is, in structural terms, a branch network of western European balance sheets and the implications of that fact for the miracle narrative are considerably more uncomfortable than the sector’s stable headline metrics suggest.

The ownership map is not ambiguous. Santander, through its Polish subsidiary, is a major retail and corporate lender. Unicredit controls Pekao, historically one of Poland’s two systemically important banks, with a balance sheet that dwarfs most Polish corporate borrowers. ING operates one of the country’s largest digital retail franchises. BNP Paribas holds a substantial Polish commercial banking presence. Société Générale was present until relatively recently. The exceptions like PKO BP, the state-controlled savings bank and a handful of smaller domestic players do not change the structural picture: a decisive share of Polish credit creation, deposit intermediation and corporate lending is controlled by institutions whose legal headquarters, capital allocation committees and ultimate stress-response instincts sit in Amsterdam, Milan, Paris and Madrid.

This matters in ordinary times because strategic lending decisions, which sectors receive credit, at what terms, on what timeline, are made within the context of the parent institution’s overall portfolio, regulatory capital position and home-country political economy, not within the context of Polish industrial policy or Polish growth priorities. A Unicredit credit committee in Milan optimising its eastern European exposure against its Italian non-performing loan legacy and its German acquisition ambitions is not, structurally, in the business of asking what Poland needs. It is in the business of asking what Unicredit needs and Poland is one variable in that calculation among several dozen others, most of them larger and more politically proximate.

The stress scenario, however, is where the architecture becomes genuinely dangerous. Western European banking has demonstrated, across multiple crisis cycles since 2008, a consistent and entirely rational pattern: when parent institutions face capital pressure at home, they reduce exposure to peripheral subsidiaries. It is the predictable behaviour of institutions managing consolidated balance sheets under Basel capital requirements and home-country supervisory pressure. The Austrian banks behaviour in central and eastern Europe during the 2011–2012 eurozone stress period, the Swedish banks’ management of their Baltic subsidiaries during the 2008–2009 contraction and the general pattern of western European credit retrenchment across the region in every stress episode all point in the same direction: when the parent sneezes, the subsidiary’s credit supply contracts and the contraction is faster and deeper than purely domestic ownership structures would produce, because the decision is being made by someone who is not accountable to the Polish economy and is not primarily exposed to its consequences.

Poland’s specific vulnerability is amplified by the current macro environment. Italian sovereign risk, Unicredit’s home context, has not disappeared; it has been temporarily suppressed by ECB policy and the political management of spread dynamics. French banking, BNP’s home context, is navigating its own sovereign fiscal deterioration, with France running deficits that have attracted renewed ratings scrutiny and a political environment that makes structural consolidation difficult. If either parent system faces a stress event of sufficient magnitude to trigger capital repatriation logic, the transmission to Polish credit conditions is not a theoretical possibility - it is a mechanical consequence of the ownership structure and it would arrive precisely at the moment when Poland, likely facing its own cyclical or geopolitical pressures, would most require stable domestic credit supply.

The miracle narrative never prices this. It records the stable capital ratios of Polish banking subsidiaries, notes the sector’s reasonable NPL profile and presents the financial system as a quiet success story running alongside the growth numbers. What it does not record is the contingent nature of that stability - the fact that it is, in significant part, a function of the parent institutions’ current health rather than of any structural feature of the Polish financial system itself. PKO BP is genuinely Polish, genuinely large and genuinely important, but it cannot alone offset a coordinated, stress-driven retrenchment by four or five simultaneously pressured western European parents. No single domestic institution can.

There is a further, subtler dimension that connects directly to the EU transfer argument made earlier. A substantial share of the EU cohesion and RRF funds flowing into Poland passes through or alongside the banking system: financing public investment, guaranteeing private credit, supporting SME lending. The foreign-owned banks benefit from this flow in fee income, balance sheet expansion and improved asset quality on their Polish books. The EU is, in effect, partially subsidising the profitability of Italian, French and Dutch banking subsidiaries operating in Poland, generating returns that are then repatriated to parent shareholders in western Europe rather than recycled into the Polish capital base. The transfer dynamic is not unidirectional. Some portion of what Brussels sends east comes back west through dividend flows and intragroup funding margins, laundered through the P&L of banks whose Polish branding obscures their structural allegiance.

A financial system that is stable in calm weather, retrenchment-prone in stress, partially repatriating the returns of EU-funded activity and ultimately accountable to shareholders and supervisors in other countries is not the foundation of an independent economic miracle. It is a franchise arrangement - functional, profitable for the franchisor and carrying a clause in the small print that Polish policymakers have so far been fortunate enough not to have fully tested.
