Tokenization in finance means recording ownership of, or a claim on, an asset as a token on a blockchain, so it can be transferred between digital wallets. The asset can be a company share, a fund unit, a Treasury bill, gold, or dollars held in a bank. The token is only as good as the legal promise behind it: who holds the real asset, what the token entitles you to, and who you can claim against if something breaks.
The SEC’s staff put it simply in January 2026: a security does not stop being a security because it is recorded on a blockchain, and the same securities laws apply (SEC staff statement, Jan 28, 2026). Tokenization changes the record and the plumbing, not the rules.
Scope: this page covers financial assets (stocks, funds, Treasuries, gold, stablecoins) from a US investor’s point of view. It does not cover tokenization in AI language models or card-payment tokenization, which share the word but nothing else, and it does not cover crypto coins as investments. It is education, not advice. This hub links to the detailed guides: tokenized stocks, whether Americans can buy them, tokenized Treasury funds, stablecoins, USDC vs USDT and the GENIUS Act.
