Paul Brennan, King Street Capital, and the distressed debt principals reshaping European real estate credit

King Street Capital Management closed its European Real Estate Special Situations Fund II in 2025, heavily targeting debt opportunities amid persistent market dislocation, according to Real Estate Capital Europe. The fund's final close signals a decisive moment for distressed debt principals who are positioning themselves at the centre of Europe's commercial real estate credit reconfiguration.

The timing is deliberate. Europe's commercial real estate sector faces a refinancing challenge of historic proportions, and a new generation of credit-focused operators, among them Paul Brennan of King Street Capital, Roger Orf of Apollo Global Management, and Riccardo Paganelli of Actarus Investments, is deploying capital where traditional banks increasingly cannot.

How large is Europe's commercial real estate refinancing gap?

The scale of the problem is structural. According to Empira Group and AEW, the commercial real estate loan financing gap in Europe represents 13% of all European CRE loans maturing between 2025 and 2027. Existing commercial real estate loans across the continent are set to mature in both 2025 and 2026, creating a concentrated wall of debt that demands resolution.

In Germany alone, BaFin, the German Federal Financial Supervisory Authority, has flagged commercial real estate loans requiring refinancing through 2026 that represent approximately 10% of the total market, a share that banks cannot adequately serve under current regulatory frameworks, according to data cited by Asset Physics.

The constraint is not cyclical. It is regulatory. CRR III, the Capital Requirements Regulation III, took effect in January 2025, tightening capital requirements for banks on commercial real estate exposures. Industry estimates suggest the regulation has reduced traditional lending capacity by 25 to 30 percent across major European markets, creating a structural advantage for institutional debt funds and non-bank lenders.

Targeted private debt strategies will become a central element of financing solutions as traditional loan structures can no longer fully cover the needs in many sub-markets, particularly for mid-market loans between €30 million and €75 million, according to Empira Group's forward outlook for 2025 to 2027.

Who are the principals executing distressed and credit strategies?

Three figures illustrate the breadth of the alternative capital response.

Paul Brennan and King Street Capital Management represent the purest expression of the distressed debt thesis. King Street, a credit-focused platform with decades of experience in special situations investing, has turned its European real estate vehicle squarely toward the dislocation created by tightening bank credit. The final close of its European Real Estate Special Situations Fund II positions the firm to deploy capital into precisely the financing vacuum that CRR III has widened. Brennan's role within King Street's European strategy reflects a conviction that the current cycle offers asymmetric returns for disciplined credit operators willing to underwrite complexity.

Roger Orf and Apollo Global Management bring institutional scale and cross-asset experience to the European real estate credit landscape. Apollo's platform spans equity and debt, and Orf's leadership in the European segment places the firm among the most significant non-bank capital providers active on the continent. Apollo's approach to real estate credit operates within a broader alternatives framework, allowing the firm to move across capital structures and geographies with a speed that traditional lenders cannot match.

Riccardo Paganelli and Actarus Investments demonstrate how real estate operators are extending into infrastructure-adjacent strategies. Paganelli is leading a biomethane infrastructure project in Southern Italy, a venture that reflects the expanding definition of real assets and the convergence of energy transition capital with traditional real estate expertise. The project, reported by GRI Hub, underscores the willingness of experienced principals to deploy capital beyond conventional property boundaries when the risk-return profile warrants it.

Together, these three principals represent different facets of the same structural shift: the migration of financing power from regulated bank balance sheets to alternative capital platforms.

Why is Southern Europe attracting credit and equity flows simultaneously?

The refinancing gap narrative plays out with particular intensity in Southern Europe, where investment activity is accelerating even as credit conditions tighten. Southern European real estate investment across Italy, Spain, and Portugal reached levels in 2025 that represented a 19% year-on-year increase, according to Cushman & Wakefield data published via GRI Hub. Italy alone posted real estate investment volumes reflecting a 23% annual increase in 2025.

This apparent paradox, rising investment volumes alongside constrained lending, reinforces the thesis of the credit operators. Where equity capital flows in, debt must follow. Yet traditional banks, burdened by CRR III capital charges, are retreating from precisely the mid-market and transitional assets that require the most creative financing solutions. The result is a widening opportunity set for funds like King Street's Special Situations vehicle and platforms like Apollo's European credit arm.

Southern European markets also benefit from relative value dynamics. Yield compression in Northern European gateway cities has pushed institutional investors further south, but debt availability has not kept pace with equity demand. For credit-focused principals, this imbalance translates into stronger lending margins and more favourable covenant structures than would be achievable in London, Paris, or Amsterdam.

The structural advantage of non-bank lenders

The implementation of CRR III did not create the opportunity for alternative lenders. It formalised and accelerated a trend that had been building since the global financial crisis. Each successive round of bank regulation has reduced the willingness and capacity of traditional institutions to hold commercial real estate exposure, particularly on assets requiring repositioning, development financing, or bridge capital.

What distinguishes the current cycle is the magnitude and concentration of the refinancing need. With loans maturing simultaneously across multiple European markets in 2025 and 2026, borrowers face a compressed timeline and fewer bank options. Non-bank lenders equipped with dedicated fund vehicles, like King Street's Special Situations Fund II, can underwrite faster and with greater flexibility on structure, collateral, and tenor.

The mid-market segment, loans between €30 million and €75 million, represents the most acute area of need. These transactions are too large for local savings institutions but too small to attract syndicated bank solutions at competitive terms under the new capital regime. Alternative debt funds are filling this segment with increasing confidence.

Credit-focused principals now occupy a position of structural importance in European real estate capital markets. Their role is no longer opportunistic; it is foundational.

What does this mean for the European real estate investment landscape?

The rise of distressed debt and credit principals carries implications well beyond individual fund closes. As traditional banks reduce their commercial real estate exposure, the pricing and availability of debt across Europe will increasingly reflect the underwriting standards and return expectations of alternative capital providers.

For equity investors, this means higher financing costs on transitional and value-add assets, but also greater certainty of execution when working with established credit platforms. For borrowers, the shift demands a more sophisticated approach to capital structure, with earlier engagement of potential debt providers and greater willingness to accept non-bank terms.

For the broader market, the structural shift creates a new ecosystem of principal-level relationships. Leaders across Europe's real estate and infrastructure sectors are navigating this transition through platforms such as GRI Institute, where cross-border capital allocation and the convergence of equity and debt strategies are central themes of member engagement.

The principals profiled here, Paul Brennan at King Street, Roger Orf at Apollo, and Riccardo Paganelli at Actarus, represent three distinct but complementary responses to the same market reality. Europe's commercial real estate credit landscape is being reshaped by operators who combine deep sector expertise with the capital flexibility that banks can no longer provide. Their strategies will define the next phase of the continent's real estate cycle.
