Abstract
Tokenization can place transferable asset records and operating rules in a programmable environment. A programmable portfolio, however, requires more than tokenized holdings. It also needs legally meaningful ownership, settlement money, interoperable custody, valuation, asset servicing, bounded automation, and failure governance. This narrative evidence review combines academic literature on tokenization and on-chain finance with 2026 BIS and central-bank infrastructure work. It examines tokenized funds, deposits, government securities, settlement, and collateral. The evidence supports potential reductions in reconciliation and atomic settlement risk, while remaining inconclusive about broad production cost savings and liquidity. Tokenization changes the possible portfolio operating model; it does not remove issuer, legal, market, or infrastructure risk.
Keywords: tokenized assets; programmable portfolios; tokenized deposits; tokenized Treasuries; atomic settlement; collateral mobility
