Small Payment Institution

A small payment institution (SPI) is a category of payment firm under the United Kingdom's Payment Services Regulations 2017 (PSRs) that is registered, rather than authorized, by the Financial Conduct Authority (FCA). To qualify, the monthly average of its payment transactions over the previous 12 months must not exceed EUR 3 million. In return for that size limit, it faces lighter entry requirements and no ongoing capital requirement, but it cannot offer every payment service and cannot issue electronic money.

The status is used by money remitters, bill-payment services, small merchant acquirers and other early-stage payment businesses that want to operate legally without the cost of full authorization.

The category comes from an optional exemption in the EU's payment services directives, carried forward in Article 32 of the Second Payment Services Directive (PSD2), which allows member states to register smaller firms under a lighter regime. The United Kingdom implemented it in the PSRs 2017, and the regime continued in UK law after Brexit. Several EU member states offer similar registered categories, with thresholds and conditions that vary by country.

• Volume limit: monthly average payment transactions, including those executed by the firm's agents, of no more than EUR 3 million, measured over the preceding 12 months or projected for a new business.
• Good repute: the individuals responsible for management must be of good repute and have appropriate knowledge and experience.
• Location: the firm's head office and place of business must be in the United Kingdom.
• Financial crime controls: the firm must comply with the Money Laundering Regulations 2017, including customer due diligence and a documented risk-based approach, and must register its agents with the FCA.

A small payment institution cannot provide an account information service or a payment initiation service; those open-banking services require a different registration or authorization. It cannot issue e-money, which requires authorization as an electronic money institution or registration as a small electronic money institution. It also cannot hold accounts in the way a bank does or grant credit beyond the narrow limits the PSRs allow for payment firms.

An authorized payment institution must meet initial capital requirements of up to EUR 125,000, depending on its services, hold ongoing own funds, safeguard customer funds, and undergo a more detailed FCA assessment. It has no volume cap. A small payment institution has no initial or ongoing capital requirement and, under the 2017 regulations, is not obliged to safeguard customer funds, although it may choose to do so voluntarily, and many partners and banks expect it. Before Brexit, only authorized institutions could use passporting to serve other EEA countries; small payment institutions never had that right.

Small payment institutions often operate through networks of agents, such as shops that accept cash for remittances. Each payment services agent must be registered on the FCA register before acting, and the principal firm is responsible for the agent's compliance. Volumes executed by agents count toward the EUR 3 million limit, so a growing agent network can push a firm over the threshold.

The SPI category gives small operators, particularly in the remittance sector, a lawful route into the market. Critics note that the low entry bar and absence of mandatory safeguarding can leave customers exposed if a firm fails, and banks frequently treat small payment institutions as high-risk clients, which contributes to de-risking and difficulty opening accounts. The closest US analogue is a state money transmitter license, though US licensing has no general small-firm tier and requires federal registration as a money services business with FinCEN.
