Regulation S lets you sell security tokens to non-US investors without registering the offering with the SEC, as long as the sale genuinely happens offshore. For a US issuer, it is the exemption that opens your raise to a global investor base - often run alongside a Reg D tranche for US accredited investors. The key obligations are keeping the offering offshore, excluding US persons, and observing a compliance period before tokens can flow back into the US market.

What Reg S is for

Reg S exists so a US issuer can raise internationally without triggering full US registration. The theory is simple: if the securities are offered and sold outside the US to non-US buyers, US registration should not apply.

For tokenized deals, this is powerful - you can reach investors worldwide, and many RWA offerings run a Reg S tranche precisely to widen the pool beyond US accredited investors.

Keeping it genuinely offshore

The exemption depends on the offering actually staying offshore. You must sell only to non-US persons, avoid "directed selling efforts" aimed at the US market, and screen buyers by residency. Platforms enforce this by blocking US persons and, for separate legal reasons, certain restricted jurisdictions.

Selling a Reg S token to a US person can break the exemption for the whole offering - so the screening is strict and non-negotiable.

The categories

Reg S sorts offerings into categories based on the issuer's connection to the US market. The more US nexus an issuer has, the stricter the conditions - chiefly a longer compliance period and more selling restrictions.

As the issuer, you (with counsel) determine your category, and it drives the rules you and your investors must follow after the sale.

The compliance period

Reg S securities carry a resale restriction - a distribution-compliance period during which the tokens cannot be sold to US persons. Depending on category, this runs from roughly 40 days to a year.

For tokens, this is usually enforced in code: the contract blocks transfers to non-eligible wallets until the period ends. Build this into your token from the start, not as an afterthought.

Pairing Reg S with Reg D

A common structure runs two tranches: Reg D for US accredited investors and Reg S for non-US investors, in one coordinated raise. Done carefully, it lets you reach both audiences lawfully. The combination has its own rules, covered in the B5 cluster. For how your overseas investors experience all this, see Reg S from the investor's side.
