Pope Francis's Final Encyclical on Money: Investment Implications

Francis never wrote a final encyclical on money. His last one, Dilexit Nos, came out on 24 October 2024 and it is about the Sacred Heart of Jesus. Six months later he was dead, on 21 April 2025, and Leo XIV was elected on 8 May.

So if you came looking for a single capstone document that tells Catholic investors what to own, it does not exist. What does exist is a body of economic teaching spread across four encyclicals, one Curial instruction, one exhortation he started and never finished, and a Pontifical Academy working paper that a lot of asset managers now cite as if it were binding. That is the actual material. Let me walk through what each piece does and does not oblige you to do.

Why Dilexit Nos still shows up in the money conversation

Dilexit Nos is a devotional text about the heart of Christ, and roughly the first two thirds of it has nothing to do with markets. The reason it keeps getting pulled into investment discussions is a stretch of paragraphs near the end where Francis argues that a society organized around consumption produces people who cannot love, and that the technocratic drive he had already attacked in Laudato Si' had by then colonized the interior life. He connects unrestrained consumerism to a kind of spiritual thinning out.

That is a real argument, and it is a genuine capstone to his economic thought in the sense that it names the psychology underneath the system he spent twelve years criticizing. It gives you no screening criteria whatsoever. Anyone selling you a fund on the strength of Dilexit Nos is doing marketing.

The documents that actually carry the money teaching

Fratelli Tutti (2020)

This is the social encyclical, and it is where the hardest economic language sits. Francis rejects the "magic theories" of market self-correction, argues that the right to private property is secondary to the universal destination of goods, and treats speculation that generates no real output as a moral failure rather than a neutral market function. He also attacks the arms trade directly, which matters because that is one of the few places where the papal teaching lines up cleanly with a hard exclusion list.

Oeconomicae et pecuniariae quaestiones (2018)

If you only read one document, read this one. It came jointly from the Congregation for the Doctrine of the Faith and the Dicastery for Promoting Integral Human Development, and it is startlingly specific for a Vatican text. It names credit default swaps bought by parties with no insurable interest, calls out securitization structures that hide risk from the ultimate holder, criticizes high-frequency trading, and takes a hard line on offshore vehicles used to strip tax base out of the countries where value was actually created. It also discusses benchmark manipulation.

The reasoning behind those calls is more mechanical than moral scolding. The objection to naked CDS is that you are creating a payoff that rises when someone else fails, with no underlying exposure to hedge, which turns another party's ruin into your revenue line. The objection to opaque securitization is that the person bearing the risk cannot price it.

Laudate Deum (2023)

A short, irritated follow-up to Laudato Si' aimed at the failure of climate negotiations. Its main contribution for investors is that it hardens the environmental teaching from "care for creation" into an explicit accusation that certain actors delayed on purpose.

Dilexi Te (2025)

Francis began this exhortation on love for the poor and did not live to sign it. Leo XIV completed it and released it in October 2025, stating plainly that he was taking up his predecessor's work as his own. In substance it is the closest thing to a final economic testament, and it centers the claim that poverty is structural rather than incidental. The investment implication is directional: it pushes toward positive allocation into things that reach people the ordinary capital markets do not reach.

Mensuram Bonam is the operating manual, not the magisterium

Mensuram Bonam came out of the Pontifical Academy of Social Sciences in 2022 under the subtitle "Faith-Based Measures for Catholic Investors: A Starting Point and Call to Action." It is the document that tries to convert all of the above into something an investment committee can act on, covering exclusions, engagement, positive screening and governance.

Two things about it get misrepresented constantly. First, the Pontifical Academy is an advisory body, so this is a consultative working paper and not an act of the magisterium. It binds nobody. Second, its own text describes itself as a starting point and invites revision, which is a strange thing to build a compliance framework on.

The one Catholic screen with real institutional force in the United States remains the USCCB Socially Responsible Investment Guidelines, revised in 2021. Those cover protecting human life, promoting human dignity, reducing arms production, pursuing economic justice, protecting the environment, and encouraging corporate responsibility. If you want the mechanical version of how exclusion lists like this get applied to a real ticker, our screening methodology shows the actual test order.

What the teaching rules out, and what it only leans against

Speculation

The hard prohibition zone is narrow and specific. Naked credit default swaps, deliberately opaque securitization, and structures whose only function is regulatory or tax arbitrage. The Vatican applies a version of this to itself: its own 2022 investment policy bars derivatives used speculatively and short selling, alongside exclusions for weapons, pornography, gambling and abortifacients.

Retail investors rarely touch naked CDS. Where this actually bites is options selling for income against nothing, leveraged and inverse ETFs held for weeks, and short-dated contract flipping. Buying a leveraged ETF is not the same category of act as writing protection on a bond you do not own, and the teaching does not pretend otherwise, but the underlying complaint about a payoff detached from any productive claim applies to both.

Fossil fuels

The environmental teaching is intense and the exclusion is soft. Francis never called for blanket divestment from oil and gas. Laudato Si' and Laudate Deum together support pressure, engagement and a preference for credible transition, and the USCCB guidelines treat environmental harm as an engagement priority rather than an automatic screen out. Someone telling you the papal teaching mandates zero exposure to XOM or CVX is adding a rule that no document contains.

ESG ratings

No pope has endorsed MSCI, Sustainalytics, or any other third-party score, and Mensuram Bonam is explicit that Catholic criteria and generic ESG are different animals. A fund that screens on carbon intensity and board diversity while holding contraceptive manufacturers fails USCCB criteria on life issues while scoring well on ESG. You can see this split for yourself by running a broad ESG fund and a Catholic-screened fund side by side in the fund comparison tool.

How the other frameworks answer the same questions

Francis and Islamic finance land in similar territory on speculation and arrive there by completely different machinery. Islamic screening runs on quantities. Under AAOIFI Shariah Standard 21, a company generally fails if interest-bearing debt exceeds roughly 30 percent of market capitalization, if cash plus interest-bearing securities breaches a similar ceiling, and if income from non-compliant sources tops 5 percent of total revenue, with that portion purified through charity. The prohibitions behind it are textual: riba al-nasiah from Quran 2:275 through 2:279, and gharar and maysir from the hadith literature. A stock either passes the ratio or it does not. Run any ticker through the stock screener and you get a number and a verdict, which is precisely what Catholic teaching declines to give you.

Biblically Responsible Investing, as practiced by Timothy Plan and Inspire, is closer to the USCCB on life issues and much further from Francis on the environment. Most BRI screens do not exclude fossil fuel producers at all, and some explicitly reject climate-based screening as a political rather than scriptural criterion. Two Christian frameworks, opposite conclusions on the same holding.

Jewish halakhic screening is narrower still. The Bais HaVaad framework concentrates on ribbis, distinguishing biblical from rabbinic prohibition and using the heter iska to restructure an interest arrangement as a profit-sharing partnership. There is no equivalent doctrinal machinery aimed at speculation as such, though the lifnei iver principle covers enabling wrongdoing by others.

The LDS parallel is the most direct. Dallin H. Oaks warned in 1971 against speculation, gambling and get-rich-quick schemes in terms a reader of Oeconomicae et pecuniariae quaestiones would recognize immediately, and the emphasis on provident living and debt avoidance pushes in the same direction Francis pushed. Neither tradition converts the warning into a ratio.

Crypto is where all five frameworks are genuinely unresolved. Francis said nothing about it. Among Islamic scholars the split runs between Mufti Taqi Usmani and the Karachi position that most tokens lack mal status, and the Malaysian Securities Commission Shariah Advisory Council view that digital assets can qualify as tradable property. Our crypto screening covers 3,300 plus tokens and shows which side of that divide a given asset falls on.

Where this leaves Leo XIV

Leo XIV chose his name with reference to Leo XIII and Rerum Novarum, and told the cardinals that the new industrial revolution he had in mind was artificial intelligence. Completing Dilexi Te signals continuity on the poverty side. What he has not yet done is issue anything that supersedes Oeconomicae et pecuniariae quaestiones or upgrade Mensuram Bonam from advisory paper to binding instruction, so the operational picture for a Catholic investor is unchanged from 2024.

The Bottom Line

There is no final Francis encyclical on money. The enforceable Catholic screen in the United States is the 2021 USCCB guidelines; the sharpest technical prohibitions sit in the 2018 Oeconomicae et pecuniariae quaestiones and cover naked CDS, opaque securitization and tax-haven structuring; everything else in the Francis corpus is directional and requires your own judgment to apply. The thing to remember is the asymmetry: Catholic teaching gives you a strong reason to care about climate and labor without giving you a threshold, while Islamic screening gives you a 30 percent and 5 percent threshold without much to say about carbon. Knowing which kind of guidance you are holding stops you from over-claiming either one.
