The Vatican's New Investment Guidelines: What Changed in 2024

A lot of Catholic investing content from the last two years opens with some version of "the Vatican released new investment guidelines in 2024." Before you rebuild a portfolio around that, it is worth being precise about which documents actually exist, when they were issued, and what authority they carry. The short version is that the rulebook Catholic institutions are working from was written in 2022, and what moved in 2023 and 2024 was enforcement, money, and personnel rather than doctrine.

That distinction matters for screening. If you think a fresh set of exclusions landed in late 2024, you will go hunting for a list that does not exist. If you understand what the 2022 texts say and how the Holy See has been implementing them since, you get something much more usable.

The two documents people conflate

There are two separate things published in 2022, from two different parts of the Church, and almost every confused article treats them as one.

The first is Mensuram Bonam, released in November 2022 by the Pontifical Academy of Social Sciences, with Cardinal Peter Turkson as Chancellor of the Academy. Its subtitle tells you its ambition honestly: it presents itself as a starting point and a call to action for Catholic investors, not a canonical rule. It sets out a framework of "faith-consistent investing" rooted in Catholic Social Teaching, leaning on Laudato Si', Fratelli Tutti and Caritas in Veritate, and it includes an annex of negative screening categories assembled from what Catholic institutional investors were already doing. Think abortion and abortifacients, contraception, embryonic stem cell research and human cloning, pornography, indiscriminate weapons, tobacco, gambling, predatory lending, and human rights abuses in supply chains.

The second is the Investment Policy of the Holy See and Vatican City State, approved in July 2022 and published that September by the Secretariat for the Economy. This one is binding, but only inside the walls. It governs how Vatican entities invest their own reserves. It requires that holdings be consistent with Church doctrine, it discourages speculative activity (derivatives used to speculate, short selling, that whole family of instruments), it steers money toward regulated markets rather than opaque private deals, and it channels assets through APSA, the Administration of the Patrimony of the Apostolic See. Praedicate Evangelium, the 2022 curial reform constitution, created the Committee for Investments that oversees it.

Neither text binds you as a lay Catholic. Neither binds Ave Maria Mutual Funds, Knights of Columbus Asset Advisors, or any diocesan endowment in the United States. They are moral guidance and internal policy respectively.

So what actually changed around 2024

The movement was institutional rather than doctrinal. The Vatican spent 2023 and 2024 consolidating financial assets under APSA and forcing entities that had run their own portfolios for decades to hand them over. That process ran behind schedule and required extensions. The Committee for Investments went from being a paper body to one that actually reviews mandates. In December 2023 the Becciu trial ended in convictions tied to the Sloane Avenue property purchase in London, which was the whole reason the anti-speculation language exists in the 2022 policy in the first place. That verdict is the practical enforcement of the investment policy far more than any new circular would have been.

In late 2024 Pope Francis addressed the Holy See's pension fund, which carries a structural imbalance between what it owes and what it holds, and placed it under a single administrator, Cardinal Kevin Farrell. That is a funding and governance move rather than a screening move, but it tells you what Rome was actually worried about in 2024. The pressure was on solvency and control, not on drafting a longer exclusion list.

If you have read a claim about a 94-page supplement to Mensuram Bonam issued jointly with the Dicastery for Promoting Integral Human Development in November 2024, treat it as unverified until you can put your hands on the document itself. I could not locate it. Page counts, joint issuers and publication months are exactly the details that get invented in secondhand summaries, and a Catholic screening policy is a bad thing to build on a citation you cannot check.

The USCCB guidelines are the ones that actually bind US Catholic money

For an American Catholic, the more operationally relevant document is the USCCB Socially Responsible Investment Guidelines, revised and approved by the bishops in 2021 to replace the 2003 version. Diocesan funds, Catholic hospital systems and Catholic universities in the US generally build their policies off these, not off Mensuram Bonam.

They organize around six policy areas: protecting human life, promoting human dignity, reducing arms production, pursuing economic justice, protecting the environment, and encouraging corporate responsibility. Each area pairs a screening posture with an engagement posture, so a company can fall into "avoid" for direct involvement in abortion or abortifacients while a labor practices concern instead triggers shareholder engagement and proxy voting.

That engagement-versus-exclusion balance was already in the USCCB text in 2021. Mensuram Bonam reinforced it in 2022. The idea that engagement became the default only in 2024 gets the timeline backwards.

Where the two Catholic frameworks genuinely differ

The USCCB approach draws harder bright lines on life issues. Direct participation in abortion, abortifacients, contraception and embryonic stem cell research is an exclusion, full stop, with no engagement pathway. Mensuram Bonam is more comfortable sitting with discernment and gradation, partly because it was written for a global audience whose local markets and legal regimes differ enormously.

On weapons, both texts are stricter than a generic ESG fund. The USCCB language on reducing arms production has historically been read to exclude producers of weapons of indiscriminate destruction, including landmines, cluster munitions and nuclear weapons systems, while leaving room for conventional defense suppliers under just war reasoning. This is a reasoned reading of the guidelines rather than a numeric rule, and different Catholic managers land in different places on the same defense prime.

How to turn any of this into an actual screen

None of these documents give you a revenue threshold. That is the practical gap. Islamic screening has hard numbers to argue about. Catholic screening mostly has categories and judgment.

Most Catholic managers close that gap by borrowing the mechanics that Shariah screening made standard. A common construction looks like this:

• Zero tolerance on direct involvement in abortion, abortifacients, embryonic stem cell research and human cloning, with no revenue floor at all.
• A 5 percent revenue test for indirect or ancillary exposure, which is the same de minimis level AAOIFI uses for impermissible income in Islamic screening.
• Engagement rather than exclusion for labor, environmental and governance concerns, tracked through actual proxy votes and resolutions.

The edge case that breaks most naive screens is the diversified pharmaceutical company. A large pharma with one contraceptive or abortifacient line inside an otherwise oncology and vaccines business will fail a strict USCCB life screen on direct involvement, regardless of how small that line is as a share of revenue. A different manager applying a materiality test will hold it and file resolutions. Both are defensible under the published guidance, which is why two funds that both call themselves Catholic can hold opposite positions on the same ticker. If that matters to you, read the manager's own screening policy rather than the label. You can compare how the frameworks stack up side by side on our methodology page.

The second edge case is the index fund. If your Catholic allocation is a broad market index wrapper, nobody is engaging on your behalf in any meaningful way, and the exclusions are whatever the index provider decided. Neither the 2022 Vatican texts nor the USCCB guidelines resolve what a Catholic investor should do about passive vehicles, and that silence is real.

Where the other frameworks land on the same questions

FaithScreener runs five frameworks, and the Vatican question is a good stress test for how differently they behave.

Islamic. Shariah screening does not use Catholic categories at all. It runs a business activity screen (no alcohol, pork, conventional finance, gambling, adult entertainment, tobacco under most methodologies) plus financial ratio screens. AAOIFI caps interest-bearing debt at 30 percent of market capitalization and interest-bearing investments at 30 percent, with impermissible income capped at 5 percent and purified out. Dow Jones Islamic Market and S&P use trailing 36-month average market cap as the denominator, FTSE and MSCI use total assets, which changes outcomes for the same company. Note what Islamic screening does not exclude that Catholic screening does: contraceptives and abortifacients are not standard Shariah screening categories, since the fiqh discussion there runs through medical ethics rather than through the ratio screens you can run on any ticker.

Christian BRI. Biblically Responsible Investing screens across six areas, typically abortion, pornography, addictive products including alcohol, tobacco and gambling, anti-family entertainment, human rights abuses, and in many implementations LGBTQ advocacy funding. BRI overlaps heavily with USCCB on life issues and diverges on alcohol, which most Catholic screens do not treat as an exclusion category at all.

Jewish Halakhic. The dominant concern is ribbis, not sector exclusion. Bais HaVaad and similar authorities apply a two-tier analysis distinguishing biblical from rabbinic interest prohibitions, and Jewish-owned enterprises typically resolve interest exposure through a heter iska, restructuring the loan as a profit-sharing partnership. A Jewish investor evaluating a Vatican-screened Catholic fund would find the life-issue exclusions irrelevant to halakhic analysis and would care about something the Catholic documents barely address.

LDS. There is no institutional exclusion list comparable to the USCCB guidelines. The most cited guidance is Dallin H. Oaks in 1971 warning members away from speculation and get-rich-quick schemes, which lines up neatly with the 2022 Holy See policy's own hostility to speculative instruments. Both traditions converge on prudence in the vehicle even where they diverge on the sector.

The Bottom Line

The operative Vatican investment texts are Mensuram Bonam and the Holy See Investment Policy, both from 2022. What changed through 2024 was implementation: assets consolidated under APSA, the Becciu convictions in December 2023 giving the anti-speculation rules teeth, and the pension fund placed under a single administrator. If you invest as an American Catholic, the USCCB Socially Responsible Investment Guidelines revised in 2021 are the document that actually shapes the funds you can buy, and their six policy areas are the thing to screen against. The one thing to remember is that no Catholic document gives you a revenue threshold, so any specific percentage you see in a fund prospectus is that manager's judgment call, and you should read it rather than trust the label.
