(ZENIT News / Vatican City, 02.11.2026).- The Vatican is tightening the link between faith and finance. In a move that signals a new phase in the professionalization of its economic governance, the Institute for the Works of Religion (IOR), widely known as the Vatican Bank, has unveiled two stock market indices designed explicitly for Catholic investors: the Morningstar IOR Eurozone Catholic Principles and the Morningstar IOR US Catholic Principles.
The initiative, developed in partnership with the global financial analytics firm Morningstar, marks a shift from general ethical commitments to measurable financial architecture. Rather than relying solely on internal screening policies, the IOR is now offering structured benchmarks that translate Catholic moral teaching into quantifiable investment criteria.
Each index comprises 50 issuers, focusing on mid- and large-cap companies within their respective markets — the Eurozone and the United States. The choice of limited, carefully selected components reflects a deliberate emphasis on quality and compliance rather than sheer diversification. These are not symbolic lists. They are constructed according to internationally recognized financial methodologies, enabling performance tracking, risk comparison and portfolio alignment with established market standards.
In practical terms, this means Catholic institutions and investors — dioceses, religious orders, foundations or lay-managed funds — now have objective reference points against which to measure whether their investments align with Church teaching. The indices are designed to meet the same technical expectations as mainstream financial benchmarks, while embedding ethical filters grounded in Catholic principles.
Giovanni Boscia, the IOR’s deputy director and head of asset management, has indicated that the introduction of these indices strengthens internal evaluation processes and enhances accountability. Performance can now be assessed not only in terms of return, but also in coherence with moral criteria. In financial governance, benchmarks are more than tools — they define what “success” means. By creating these indices, the IOR is effectively redefining that metric.
The launch must also be understood within a broader evolution of the Vatican’s financial reforms over the past decade. Since efforts began to modernize oversight mechanisms and align with international transparency standards, the Holy See has sought to move beyond reputational recovery toward institutional credibility. The creation of Catholic-principled indices represents a maturation of that process: ethics is no longer an external constraint but a structural component of financial strategy.
Morningstar, for its part, has noted the growing demand among investors for benchmarks that reflect specific values or policy frameworks. The expansion of environmental, social and governance (ESG) investing has demonstrated that markets respond to moral narratives when they are translated into technical criteria. The Vatican’s approach, however, does not simply replicate ESG logic; it draws from the Social Doctrine of the Church, a body of teaching that addresses human dignity, solidarity, subsidiarity and the common good.
For readers less familiar with Catholic social teaching, it is worth noting that the Church’s economic reflections date back at least to Pope Leo XIII’s 1891 encyclical Rerum Novarum, which addressed labor rights and capital. Over time, this tradition has expanded to cover global development, ethical finance and the moral responsibilities of economic actors. By embedding these principles into formal indices, the IOR is effectively codifying that tradition within contemporary capital markets.
The strategic dimension is clear. The Vatican Bank is not merely adjusting its own portfolio; it is proposing a transparent and replicable standard for the wider financial community. If adopted by other Catholic-linked institutions, these benchmarks could influence asset allocation decisions well beyond Vatican walls.
Ultimately, the significance of the Morningstar IOR Eurozone Catholic Principles and Morningstar IOR US Catholic Principles indices lies in their ambition. They aim to demonstrate that profitability and principle are not mutually exclusive. The Vatican has chosen to enter the arena with data, methodology and measurable standards — an assertion that capital, too, can be directed toward the common good without abandoning professional rigor.
