The failure of the Vatican bank to comply with the basic rule of the Sacrament of Penance is odd. The Holy See’s financial arm has been seeking absolution for past sins for two years, but remains reluctant to confess to what it did wrong. Of all institutions, it should understand that one cannot go without the other.

According to Italian newspapers, JPMorgan Chase is closing the account of the bank formerly known as Istituto per le Opere di Religione (IOR) because of concerns about a lack of transparency. The move comes a few weeks after the U.S. State Department added the Vatican to the list of countries it considers vulnerable to money laundering.

JPMorgan’s move is no administrative tidying-up: some 1.5 billion euros is reported to have passed through the account in the past 18 months. Yet considering the reputational beating that investment banks have taken in recent years, it’s refreshing that one of them is concerned about being tainted by its association with the Vatican.

The latest stigma may look unfair on the Vatican bank’s new management team, installed two years ago with the explicit task of breaking with its shady past. After all, the lender has wrestled for thirty years with its involvement in the fraudulent collapse of Banco Ambrosiano, Italy’s largest private bank, in which it held a small stake.
