Hey, it’s Marc.

I watched DTCC’s live updates on Wednesday like a product launch. In a way, it was one.

At 8:30am, JPMorgan converted QQQ shares into tokens. By late morning, it posted tokenized assets to meet a margin call at CME.

Real securities. Real margin. Live production.

DTCC just shipped what crypto spent a decade promising. Let’s unpack.

What happened

On July 15, DTCC converted securities held at its DTC depository into tokens and used them in live production trades. The firm calls it the largest tokenization production event yet by use cases, asset classes, and participants. More than 30 firms took part, including BlackRock, JPMorgan, Goldman Sachs, Vanguard, Citadel Securities, Circle, and CME Group. Trades settled on Hyperledger Besu, DTCC’s private network, and Canton, a public network built for regulated finance.

The workflows were pure back office: collateral pledges, securities lending, Treasury repo, equity trades, and clearinghouse margin. JPMorgan tokenized Invesco QQQ holdings, then posted tokens to meet margin requirements at CME. Societe Generale pledged tokenized Treasuries to Citadel Securities. Microsoft and Circle shares, SPY, and Treasuries across maturities were tokenized during the day.
