The Aggregation Trap: Minority Stakes and the 50 Percent Rule
Meridian Petrochem Trading Ltd is a UAE free-zone commodity trader applying for a USD operating account at a Singapore bank. Its shareholder register shows: (i) Ardent Assets Ltd at 26%, designated by OFAC in 2023; (ii) Crestline Holdings Ltd at 24%, wholly owned by a separate OFAC-designated individual; (iii) a Cayman fund holding 4%, in which the same Ardent-designated owner holds exactly 50%; (iv) a Gulf family office at 40%; and (v) management at 6%. No shareholder is a US person. The relationship manager notes Meridian has never appeared on any sanctions list and that the two largest outside holders are just financial investors. The KYC file records the ownership chain but contains no sanctions ownership analysis.

Conclusion: yes, Meridian is blocked property by operation of law.
Apply the 50 percent rule, which blocks any entity in which one or more blocked persons hold, directly or indirectly, a 50 percent or greater ownership interest in the aggregate. Aggregation across distinct blocked persons is mandatory, not a discretionary choice:
- Ardent Assets: 26% direct.
- Crestline: 24%, but Crestline is wholly owned by a designated individual, so 100% of that 24% is attributable.
- Cayman fund: the fund itself is blocked because a designated person owns exactly 50% of it (50% is sufficient). Its 4% stake in Meridian is therefore blocked property, and the designated person's interest in it is 50% x 4% = 2%.
Total attributable interest: 26 + 24 + 2 = 52%, above the threshold.
Key points for the file: no listing action is required and the absence of Meridian from the SDN list is irrelevant; blocking attaches automatically. Because the account would be USD-denominated and cleared through the United States, there is a clear US nexus, and the Singapore bank also faces MAS supervisory expectations regardless. Note also that even below 50%, control indicators (signature authority, POAs, financing dependence) can independently justify treating an entity as blocked or at minimum as requiring enhanced measures.
2. The relationship manager argues the Cayman fund stake is passive LP money and should not count. How do you respond, and what operational steps follow if the account is opened or an existing balance exists?

Refute the argument on the mechanics of the rule. The 50 percent rule is applied link by link through the ownership chain. The question is not whether the fund is passive; it is whether a blocked person owns 50% or more of the fund. At exactly 50%, the fund is blocked property, so its assets, including the Meridian shares, are blocked. A minority, non-controlling stake held by a blocked entity is still blocked property. There is no de minimis exception and no passivity carve-out.
Operational steps:
- Do not onboard for general use; treat any funds received as blocked property and place them in a blocked, interest-bearing account (blocked funds should not be commingled with operating funds).
- File a blocked property report with OFAC within 10 business days, and make the corresponding report under the applicable local regime (for Singapore, to MAS as required).
- Do not return, offset, or release the funds; do not process payments in or out.
- Consult counsel before communicating with the customer, and avoid any step that could enable dissipation of assets.
- Screen the fund's other holdings and the family office for further links, and set the ownership chain for annual re-review plus event-driven review on any list change.
- Document the reasoning contemporaneously. Regulators assess whether the analysis was made, not whether the conclusion happened to be right.
3. Suppose the diligence had instead found that Crestline is owned 49% by the designated individual and 51% by an unlisted party. Would your conclusion change, and what residual risk remains?
Read the worked answer
The ownership conclusion changes, but the file does not close.
Recalculate the chain: Crestline is not itself blocked because the designated person holds only 49%. His indirect interest in Meridian is therefore 49% x 24% = 11.76%, which is attributable. Total attributable = 26 (Ardent) + 11.76 (Crestline) + 2 (fund) = 39.76%, below 50%. Meridian is not blocked on an ownership basis.
Residual risk and next steps:
- Control is a separate basis for blocking. Look for the designated person's influence over Crestline or Meridian: board seats, veto rights, shareholder agreements, POAs, funding dependence, or family relationships with the 51% holder. If a blocked person controls the entity, it can be treated as blocked even at low ownership.
- Jurisdictional divergence. The EU applies a comparable 50% ownership test, while the UK tests both ownership and control; a structure that fails one test may pass another. Screen against every applicable regime, not just OFAC.
- Evasion risk. A structure sitting at 49% and 39.76% invites the question of whether it was deliberately engineered to sit below the line. That does not create a violation, but it justifies enhanced due diligence, senior sign-off, and periodic re-review.
- Practical position. Onboarding may proceed with documented EDD, transaction monitoring tuned to the ownership profile, and a clear escalation path if the stakes shift.
