Clearstream: one layer deeper in the custody chain

Clearstream settled at $151,902,000 in 2014. After OFAC raised its Iranian business, it moved securities entitlements so that the record owner changed and the Central Bank of Iran's beneficial interest did not.

One of the clearest illustrations of layering in the entire enforcement record, and it happens in securities custody rather than in company ownership.

The starting position

From at least December 2007 through June 2008, Clearstream — a Luxembourg securities settlement and custody institution — maintained an account at a US financial institution in New York through which the Central Bank of Iran held a beneficial ownership interest in 26 securities with a nominal value of $2.813 billion, held in custody at a central securities depository in the United States.

OFAC’s notice makes the mechanism explicit: because Clearstream’s New York account was an omnibus account, the Central Bank of Iran’s beneficial interest was not transparent to the US financial institution. Clearstream, as intermediary, was the channel through which that interest was held.

What happened after OFAC raised it

This is the part that made the case egregious rather than negligent.

OFAC officials met with Clearstream in late 2007 and early 2008 to discuss its business with Iranian clients, including implementing Clearstream’s decision to terminate it.

In February 2008, acting on instructions from the Central Bank of Iran, Clearstream transferred the securities entitlements free of payment from the Central Bank’s account with Clearstream to a newly-opened custody account held at Clearstream by a European bank.

OFAC’s description of the result is worth stating exactly: the record ownership of the securities entitlements on Clearstream’s books changed, but the beneficial ownership did not, “resulting in the CBI’s interest being buried one layer deeper in the custodial chain.” The ultimate place of custody remained the United States, and the interest continued to be held through the same omnibus account in New York.

Why this belongs on the layering page

Strip out the securities vocabulary and this is the canonical structure described in the beneficial ownership literature. A new intermediary is interposed. The register now shows a different holder. The person who benefits is unchanged. Nothing has moved except the number of steps a third party must take to establish who is behind the position.

It also demonstrates the standard that applies. OFAC found that, given the totality of the facts, Clearstream had reason to know the Central Bank was retaining beneficial ownership — the same “knew or had reason to know” test that decides the third-country transshipment cases, applied to a custodian instead of an exporter.

The numbers

The total base penalty was $5.626 billion; the settlement was $151,902,000. Aggravating factors included that Clearstream acted recklessly in failing to perform sufficient due diligence on the free-of-payment transfer, and that several employees including at least one supervisor and a senior executive had reason to know the beneficial ownership would not change.

OFAC’s own summary of the lesson: the action “highlights the particular sanctions risks faced by intermediaries, custodians, and other firms operating in the international securities markets.”

The general point

Most corporate concealment on this site concerns who owns a company. This case concerns who owns a securities position, recorded in an entirely different system. The analytical question — who holds the beneficial interest, and can the intermediary say — is identical wherever it is asked.
