Executive summary

The Institute for the Works of Religion, commonly called the Vatican Bank or IOR, has been linked repeatedly since the 1970s to money‑laundering allegations, ties to controversial Italian bankers and the Mafia, and high‑profile collapse scandals—most notably the Banco Ambrosiano affair—forcing waves of public scrutiny and legal probes that culminated in a long, piecemeal program of reform under popes Benedict XVI and Francis [1] [2] [3]. Reformers moved the IOR from secretive, clerical control toward modern governance: account closures, outside audits, restricted client rules, published reports and new compliance, though critics warn that problems of culture, immunity and governance leave gaps in accountability [4] [5] [6].

1. The 1970s: Sindona, Marcinkus and early reputational collapse

In the 1970s the IOR became entangled with Sicilian financier Michele Sindona and later with Roberto Calvi’s Banco Ambrosiano, relationships that exposed the bank to disastrous investments and raised accusations that Vatican accounts had been used to move or hide funds tied to organized crime, prompting Italian investigations into unsecured loans and suspicious transactions [7] [3] [2]. Archbishop Paul Marcinkus, appointed to run the IOR in the early 1970s despite no formal banking training, was a lightning rod in press accounts that linked the Institute to illicit transfers and large losses—reports that fed longstanding conspiracy theories about corruption at the Vatican [8] [1].

2. Banco Ambrosiano and the Calvi mystery: scandal goes international

The collapse of Banco Ambrosiano in the early 1980s—creditors said the bank had made billions in unsecured loans, some backed by vague “letters of comfort” tied to the Vatican—was a watershed: Italian magistrates investigated the IOR’s involvement, Calvi was later found dead under suspicious circumstances in London, and the Vatican agreed to sizable financial settlements while denying formal liability, leaving a legacy of opacity and suspicion [3] [9] [2].

3. Continued scandals: suspicious deals, trials and convictions

Scandals did not end with Ambrosiano; the IOR and adjacent Vatican financial bodies were repeatedly implicated in embezzlement, mismanagement and high‑profile internal disputes—examples include prosecutions and convictions of former Vatican officials and directors in the 2010s and early 2020s, and the 2019 arrest and later conviction of Cardinal Giovanni Angelo Becciu for embezzlement as part of wider abuse of Holy See funds [10] [11] [6].

4. Structural resistance and the problem of immunity

One recurring obstacle to accountability was the Vatican’s unique legal status: diplomatic immunity and internal tribunals complicated Italian and international efforts to pursue clear, public criminal accountability, a fact frequently cited by investigators and commentators as a structural impediment to transparent reform [3] [6]. At the same time, insiders and conservative defenders argued that some investigative narratives overstate criminal intent and understate the complexity of ecclesiastical finance—an alternate view that stresses institutional sovereignty and the need for careful internal reform rather than wholesale delegitimization [1] [12].

5. Reforms under Benedict and Francis: governance, compliance and transparency

From the late 2000s and accelerating under Popes Benedict XVI and Francis, the Vatican embarked on concrete reforms: appointment of lay bankers and external experts to leadership roles, closure of suspect accounts, stricter client rules limiting accounts to clerical and institutional holders, the introduction of outside audits, publication of some financial reports, and new anti‑money‑laundering compliance to meet international standards [4] [5] [13]. Pope Francis in particular pushed centralization of financial oversight, forced dormant account closures, and replaced clerical appointees with professional managers with the stated aim of bringing the IOR into “21st century” standards [5] [11].

6. Results, lingering doubts and the politics of reform

Reform yielded measurable changes—accounts closed, external consultancy brought in, and prosecutions that signalled a tougher internal stance—but journalists and watchdogs continue to flag gaps: the Vatican’s partial transparency, residual secrecy in other Vatican financial bodies, and the slow pace of cultural change mean critics remain skeptical that reforms fully eliminated past practices or neutralized entrenched power networks [4] [6] [14]. Observers also note political stakes: reforms both respond to external regulatory pressure from Italy and Europe and serve internal papal priorities—an intersection where moral credibility, institutional sovereignty and reputational repair collide [6] [13].
