Luxembourg: The revival of the Capital Markets Union project has gained political prominence following successive Commission communications and member state declarations, but the operational architecture of the project remains contested. Luxembourg, as one of the largest investment fund centres in the world and as the seat of several European financial supervisory bodies, sits at a strategically interested vantage point in this debate. The question of whether the bloc can move beyond bank-dependent financing toward deeper capital markets has been on the agenda for more than a decade and the answers continue to elude political agreement.
The diagnostic is consistent across analyses. European companies, especially in growth sectors, are more dependent on bank financing than their American counterparts, with consequences for the cost of capital, the speed of scaling and the eventual location of headquarters when companies seek public listings. European household savings, which exceed twenty trillion euros in aggregate, are disproportionately allocated to bank deposits and life insurance products with relatively low equity exposure compared with American or even British household portfolios. The mismatch between the supply of savings and the demand for risk capital is at the heart of the capital markets diagnosis.
The proposed reforms cluster around several themes. Supervisory convergence is one. The current architecture, in which national supervisors retain primary responsibility for most market activities with the European Securities and Markets Authority playing a coordinating role, has produced documented divergences in supervisory practice that affect cross-border activity. Proposals for stronger central supervision in specific segments, including the supervision of central counterparties and certain investment funds, have circulated for years and continue to face national resistance. The political question is whether member states are willing to cede regulatory ground in exchange for the deeper market integration that such cession would enable.
Tax harmonisation in specific dimensions is another. The differential treatment of equity and debt financing, the variation in withholding tax procedures and the complexity of cross-border refunds have all been identified as obstacles to deeper integration. Reforms have been proposed and partially implemented, but the underlying tax sovereignty of member states limits the scope for harmonisation. The faster procedures for withholding tax relief that the recent directive introduces represent progress on one dimension without addressing the larger questions of tax incentives for equity financing.
Securitisation reform is a third theme. The European securitisation market has remained small relative to its potential, partly because of the capital requirements applied to investors and partly because of the operational complexity of the simple, transparent and standardised label. Proposals to recalibrate the capital treatment have been advanced, particularly for synthetic securitisations that allow banks to transfer credit risk, and the political case has been strengthened by the broader need to mobilise private financing for the green and digital transitions.
The pension and savings architecture is a fourth theme. Several member states have pension systems that allocate a large share of national savings to relatively safe assets through public or quasi-public schemes. Proposals to introduce European-level long-term savings products, including the pan-European personal pension product, have been advanced but uptake has been limited. The political difficulty is that pension policy is constitutionally national in most member states, and proposals that touch on it are sensitive.
Whether the next phase of the project produces substantive results will depend on the willingness of member states to accept regulatory and supervisory consequences of deeper integration. The history of capital markets union has been one of incremental progress on technical files alongside continued political resistance on the more consequential dimensions. Whether the geopolitical pressure of the current moment changes that balance is the open question.
