Tokenization in financial markets is gaining traction globally, with U.S. tokenized assets more than doubling in market capitalization over the past year to roughly $25 billion.
Federal Reserve Governor Lisa D. Cook addressed the Central Bank of West African States conference in Dakar, Senegal, laying out a measured case for the technology.
She acknowledged its promise for improving market efficiency while flagging financial stability concerns that regulators must continue to monitor carefully.
Tokenization works by generating a digital representation of an asset on distributed ledger technology, such as a blockchain.
Smart contracts — self-executing code that triggers actions when preset conditions are met — drive much of the technology’s appeal.
These tools can automate complex processes like margin calls and collateral substitutions that currently require manual steps.
Current collateral and repo market workflows are often fragmented across legacy systems. Cook said tokenization could allow recordkeeping to be streamlined, letting “parties share a single transparent source for tracking transactions and managing associated collateral.”
That fragmentation in legacy systems creates delays, errors, and added costs that the technology could help resolve.
Tokenized money market fund shares enable frequent intraday investment and redemption, improving returns on idle cash.
Tokenized repo transactions can also settle intraday rather than overnight, giving institutions faster access to liquidity.
Cook added that programmable fractional ownership could allow for “more flexible and expanded opportunities for investors” by enabling small-denomination exposure with automated transfer of ownership.
Beyond operational gains, the technology could broaden market access. Cook noted this could be particularly relevant in West Africa, where investors may have fewer resources but a clear need to build capital market participation alongside social safety nets.
Cook was equally direct about the risks that come with scaling tokenization. Some tokenized assets can be redeemed on demand, while the underlying pool of assets is less liquid.
That mismatch introduces potential run risk. Cook warned that “around-the-clock trading and settlement may speed up a run on the issuer” if disruptions occur in token markets outside normal trading hours.
Interconnectedness between tokenized assets and traditional markets adds another layer of concern. When tokenized assets serve as collateral or liquidity instruments, shocks can travel more quickly between the digital asset ecosystem and conventional financial infrastructure.
Cross-holdings between issuers could compound those effects if one issuer is forced to liquidate assets that are liabilities of another.
Operational vulnerabilities also warrant attention. Cook cautioned that as smart contracts automate more processes, “humans are less able to correct for bugs or respond to outside threats.”
Cyberattacks are relatively common in decentralized finance ecosystems, and relatively new products tend to attract malicious actors looking for exploitable gaps.
Cook stressed that understanding these tradeoffs is how regulators enable innovation to grow sustainably. The Fed is working with the Bank for International Settlements, the Financial Stability Board, and peer central banks to monitor these developments.
She reaffirmed that responsible innovation and financial stability are not competing goals, but parallel obligations for central banks worldwide.
