It appears that the US is planning to require some visitors to pay a bond of up to USD 15,000 for a visa.
Many political comments have been made about it; we would like to bring some light quant comments.
The term used for the visa is “bond”, in the market this type of requirement is called “Collateral” or “Initial Margin” (IM). The quantitative and valuation impacts of those IM requirements have been studied extensively in the literature with regard to derivatives and are known under the name MVA.
The mechanisms would be that the person requesting a visa would deposit a certain amount before using the visa and the amount would be returned when the person has departed the US.
Some parts of the mechanism are similar to IM, and thus require some MVA computations, some other parts are different and require further adjustments.
Some visas, including business visas, require a bond. This bond deposited during the length of the visa usage has some cost, for a corporation this is typically a funding cost. That means that any corporation making business with the US which requires visits from oversea staff will need to incorporate that cost to their prices. This is the MVA part.
By opposition to the standard IM practice in the OTC market, here the IM is deposited not with a third party custodian, but directly with the counterparty (the US government). On that amount there is a non-negligible credit and legal risk. What if the US defaults, or more likely refuses to pay the margin back? What for multi-entry visas? Can the US keep the bond up to the end of visa validity? What if the depositor died before claiming the amount back? Here the question moves from a MVA-like question to a CVA-like question. Involving probability of default (PD) and loss given default (LGD). The LGD may even be higher than 100% of the bond amount itself if the legal cost is added.
In all cases, corporations planning to make business with the US should analyse the potential cost of such a framework (this analysis is itself a cost). We are not experts in political risk, but we have helped clients with many Initial Margin methodologies.
