Regulatory Tracking: Distinguish the Hard from the Forbidden

The first step was to determine whether a corridor is worth entering. We did this by evaluating the corridor across four layers: market size, customer segments, demand movement, and the corridor's margin. Next, we evaluated what it takes to operate there. Is it prohibited, or is it allowed? Costs can run into multiple years and multiple millions of dollars. This step turns a good opportunity into a real one.

The next question is blunt: what is the cost of doing this, and can you actually do it? One mistake is to treat complexity as a simple rating of high, medium, or low. A corridor rated high complexity can mean three completely different things, and confusing them will lead to a wrong decision.

What this layer contains

A currency corridor is regulated on both the sending and receiving sides, and these are never symmetric. Each has its own institutions, laws, licensing regime, and complexity. There are specific restrictions on who can send and receive money, conditions for provider licensing, capital requirements, and timelines for the licence; all vary.

The most important practice in this layer is not to stop after looking at the complexity rating. The rating tells you how much work there is, but you need to determine what kind of work it is, and your readiness to do it.

How to read it

Four things matter in a read of this layer.

First, the defining side for the requirements is the stricter one to comply with. Usually, the send-side regulations are easier, and the difficulty concentrates on the receive-side. The receiving country takes in the money, converts it to its currency, and has jurisdiction over it. So a corridor's regulatory difficulty mostly comes down to the receiving side.

Second, a high complexity rating doesn't mean the corridor is prohibited from entry. High complexity can tell different things about a regime. It can indicate a regime that's elaborate yet predictable, hostile and exclusionary, or one prone to sudden shocks and frequent changes. Each scenario requires a different response. An elaborate but predictable system acts as a moat once established. In contrast, hostile or rapidly changing regimes pose ongoing business continuity risks.

Third, licensing can serve as both a barrier and a moat. Requirements like capital, application fees, and processing times are tangible entry costs, and prevent competitors from entering. Say a corridor requires two years to get a license and a million dollars in capital is challenging to enter into, but for existing players, these same requirements are a shield against new ones.

Fourth, regulation is live, not static. This layer has to be re-read to make sure the governing rules are still properly assessed and followed. Sometimes corridors change their basic behaviour: navigable corridors become hostile, or hostile ones start moving towards being open. These shifts are even stronger signals to read.

Three corridors with different meanings of "hard"

Three corridors with the same rating on the same side can still mean very different things. We can see this in live corridors.

The Hong Kong-to-Philippines corridor is a hard-but-navigable corridor. This is where regulation becomes a moat. Hong Kong's send side is transparent, predictable, and has a clean licensing framework. The Philippine receive side is also complex, but it has a well-defined structure under a specific central-bank circular. The tiers are clearly defined, with clear capital requirements and reporting thresholds. Running the corridor needs dual licensing in Hong Kong and the Philippines, with real capital requirements and a 9-to-12-month timeline. While this is hard, it is doable, and this keeps non-serious entrants out.

The UK-to-Nigeria corridor, on the other hand, can be categorised as hostile. While the UK side is clean and mid-complexity, the Nigerian side has far more difficult compliance. Some conditions are: inbound remittances must be paid in Naira, foreign-currency payouts are illegal, cash payouts above a low threshold are barred, fintechs and banks are prohibited from holding a remittance operator licence directly, and operators are banned from buying FX in the domestic market. Further, the licence has high capital requirements in addition to a non-refundable annual fee.

It is also prone to sudden and sweeping changes: in May 2026, a new rule forced all payouts through designated Naira accounts at authorised banks and funded only from specified inflows. So while the complexity rating for the Nigeria corridor is the same as Philippines, the underlying narrative tells you that the actual complexity is not. It is a shifting, changing regime that affects day-to-day operations and operating risk.

A third example is the US-to-Mexico corridor. Both sides here are rated high in complexity. Mexico runs advanced e-invoicing and tax-integration requirements, with real-time invoice validation and stamping and transaction-level clearance. The licensing process is long, often taking more than two years. The difficulty is because the process is elaborate and bureaucratic. Market entry takes significant engineering effort, and patience to navigate the licensing. However, this corridor also carries a very serious risk. In late 2025, US authorities designated three Mexican financial institutions for ties with the cartels and prohibited US institutions from transacting with them. This eventually led to the liquidation of one of the banks. Even a mature corridor can deliver an overnight shock, and a keen eye on the regulatory landscape is required to navigate it.

The trap

The biggest trap in this layer is stopping after looking at the rating without understanding the underlying narrative. Three corridors with three high-complexity receive sides can lead to three completely different businesses. If you treated them as the same, you would fear entering the Philippines too much, not fear entering Nigeria enough, and not pay attention to sudden shocks in Mexico.

The second trap is looking at it as a snapshot. While regulation changes more slowly than other layers, it is still live. The Nigerian settlement rule and the Mexican bank designation are recent events that bear testimony to this.

Even after a good understanding of the regulation, one question remains open. Being allowed to operate is not the same as being able to move the money. You need banking partners and rails to move the money reliably. That is the bridge to the next layer: banking infrastructure.
