CME Group has partnered with Google Cloud to pilot initiatives aimed at enhancing capital market efficiency through tokenization. The collaboration seeks to leverage Google Cloud Universal Ledger (GCUL).

However, critics argue that the technology represents a shift toward centralization in an industry that has traditionally prioritized decentralization.

CME and Google Cloud’s Tokenization Pilot: A New Era or Centralization Crisis?

For context, Google Cloud’s GCUL is a distributed ledger built for seamless integration by financial institutions. This platform simplifies account and asset management while enabling secure transfers on a private and permissioned network.

According to the press release, the collaboration seeks to enhance the efficiency of wholesale payments and asset tokenization by utilizing GCUL. Terry Duffy, CEO of CME Group, hailed the partnership as a response to the changing demands of global markets.

“Google Cloud Universal Ledger has the potential to deliver significant efficiencies for collateral, margin, settlement, and fee payments as the world moves toward 24/7 trading,” Duffy said.

The team has finalized the initial integration and testing phase of GCUL. They will conduct direct testing with market participants later this year. Lastly, the services’ launch is planned for 2026.

Nonetheless, the move has sparked controversy within the cryptocurrency community. Critics argue that GCUL, as a centralized and permissioned ledger, contradicts the decentralized ethos that underpins blockchain technology.

“It is not a bullish development,” a user wrote on X.

The collaboration has also ignited a broader discussion about the role of public versus private blockchains in asset tokenization. DeFi analyst Ignas framed the issue as a “battle between public, decentralized networks and private chains.

This suggested that centralized solutions like GCUL could undermine the principles of transparency and inclusivity of public blockchains.

“Not bullish at all. Google Cloud Universal Ledger (GCUL) seems to be a private, permissioned network,” he posted.

Meanwhile, another analyst pointed out the practical challenges associated with using public blockchains. 

“I’m honestly not sure if public chains are competitive in this space,” he claimed.

The analyst explained that CME Group or similar institutions require ultra-high-frequency settlements with near-instant finality. They also need room for manual intervention when necessary. 

This need for precise control often leads institutions to split blockchain nodes into specialized roles like clearing, settlement, compliance, and observation. The analyst argued that public blockchains do not support this level of control.

He also highlighted that tokenized assets need liquidity boundaries to avoid risks like money laundering and speculation. Without proper controls, tokenized assets could face these issues if traded on decentralized exchanges. 

“I’ve talked to quite a few people from traditional finance, and honestly, many of them say DEXs are basically no different from black markets,” the analyst added.

Thus, he noted that the concerns around regulation, scalability, and security make it a difficult proposition for traditional financial institutions to adopt tokenizing real-world assets directly on a public blockchain.
