Regulatory Arbitrage

Regulatory arbitrage is the practice of structuring a business, product or transaction so that it is governed by a lighter, cheaper or more favorable set of rules than would apply to the same activity in another form or place, while the economic substance for customers stays largely the same. The term borrows from arbitrage in markets, where a trader profits from a price difference for the same asset; here the "price" is the cost of complying with regulation.

Regulatory arbitrage covers a wide spectrum. At one end is legitimate jurisdiction selection, such as choosing to license a payment firm where the regulator is efficient and the rules fit the business model. At the other end are structures designed mainly to avoid rules that would otherwise apply, which supervisors regard as a risk to be closed down.

Jurisdictional arbitrage

A firm locates its licensed entity in a jurisdiction with lower capital requirements, faster licensing or lighter supervision, and then serves customers elsewhere. Within the European Economic Area, passporting allows a firm authorized in one member state to serve the others, which created an incentive to seek authorization where approval was quickest. Use of an offshore financial centre or a financial free zone can serve the same purpose, and supervisors respond with requirements for real economic substance and local management.

Charter and license arbitrage

A firm chooses the type of license that carries the fewest obligations for what it wants to do. In the United States, a company may seek a state money transmitter license, a trust charter, an industrial bank charter or a partnership with a sponsor bank, each with different supervisors and capital rules. Business models that rely on the agent of the payee exemption, or that frame a service so it falls outside the definition of money transmission, are often described as regulatory arbitrage when the customer experience is identical to licensed transmission.

Product and accounting arbitrage

The best-known financial example came from bank capital rules. Under Basel I, banks could reduce the regulatory capital they held by moving loans into securitization vehicles or off-balance-sheet conduits while keeping much of the risk through liquidity lines and guarantees. Those structures, together with the growth of shadow banking outside the regulated perimeter, contributed to the 2008 financial crisis. Basel II and Basel III were designed partly to close these gaps.

Crypto and new technology

Digital-asset businesses have often launched in jurisdictions with no specific crypto regime or with permissive early rules. Comprehensive frameworks such as the EU's MiCA and the FATF standards for virtual asset service providers aim to reduce the scope for this by applying common requirements across jurisdictions.

Not every case of choosing a lighter regime is improper. Regulators deliberately create proportionate regimes, such as the small payment institution category or regulatory sandboxes, so that firms can choose the license that fits their scale. Choosing an efficient, well-regarded regulator can also make a firm more acceptable to banks and partners.

Supervisors become concerned when a structure satisfies the letter of a rule but defeats its purpose: when the activity, risk or customer base is in one place and the license in another, when the firm has no real presence where it is supervised, or when the structure leaves customers without protections they would otherwise have, such as safeguarding of funds. The risk-based approach used by AML supervisors also looks through structures to where the risk actually sits.

• Regulatory reclassification: a regulator may conclude that the activity requires a license after all, leading to enforcement, fines or a forced restructuring.
• Banking access: correspondent and sponsor banks often view arbitrage structures as high risk, which can lead to de-risking and account closures.
• Rule changes: gaps tend to be closed once they are widely used, so a business model built on one may not last.
• Systemic risk: at scale, activity migrating to lightly regulated corners of the system can build up hidden leverage or liquidity risk.

Regulators respond through cooperation and convergence: international standards from the Basel Committee, FATF and IOSCO, information sharing between supervisors, substance requirements for licensed entities, and activity-based rules that apply whatever the legal form. Within the United States, efforts such as the Money Transmission Modernization Act aim to harmonize state rules and reduce differences between states that firms could exploit.
