Wall Street's embrace of tokenization has pushed the total real-world asset (RWA) market past $37 billion this week. But a key question still divides the industry: should these assets live on public or private blockchains? Banks appear to have made their pick, though the debate isn't over.
The $37B Milestone
The tokenization of real-world assets — think bonds, real estate, commodities — has quietly become one of crypto's biggest growth stories. The market crossed $37 billion in total value this month, up from just a few billion a couple of years ago. Major banks and asset managers are now moving real products onto blockchains, not just experimenting.
That number covers everything from tokenized Treasury bills to private credit funds. It's still small next to traditional finance, but the growth rate has caught the attention of regulators and competitors alike.
Public vs. Private: The Bank Choice
For years, the crypto world argued over whether tokenized assets should run on public blockchains like Ethereum or on permissioned, private networks. Banks, it turns out, have made a decision. They're mostly going with private blockchains — at least for now.
Why? Control and compliance. Private chains let banks know exactly who's validating transactions and who's holding the assets. That matters when you're dealing with securities laws and anti-money laundering rules. Public blockchains offer more liquidity and composability, but they also come with open access and less oversight.
The choice isn't final. Some firms are building bridges between the two worlds. But the early money is on private infrastructure, and that shapes everything from custody to settlement.
The debate isn't dead — it's just shifted. Now the question is whether public blockchains can evolve to meet institutional standards, or whether private networks will dominate the RWA space for the foreseeable future.
The next big test comes when regulators start issuing formal guidance on tokenized assets. That's expected later this year. Until then, banks will keep building on the rails they trust, and the $37 billion figure will keep climbing.
