Crypto should adopt the best of centralization, says LMAX CEO

For years, crypto's ideological center of gravity has been pulled toward decentralization.

David Mercer, CEO of institutional trading venue operator LMAX Group, however says digital assets may need more centralization if the industry hopes to achieve its next phase of growth.

"Centralization solves the coordination problem," Mercer told CoinDesk in an interview. "Buyers and sellers get the best prices by participating in a single central market."

History demonstrates that even the industry's most decentralized experiments eventually gravitate toward centralized points of coordination, he added.

From early peer-to-peer marketplaces to decentralized finance (DeFi) protocols that have intervened during crises, market participants consistently rely on trusted venues, governance structures and settlement mechanisms when volatility strikes.

"Crypto needs to learn from hundreds of years of organized capital markets," he says.

LMAX Group is a London-based financial technology company that runs institutional trading venues for foreign exchange and digital assets. Its platforms provide banks, funds, brokers and other professional traders with regulated exchange-style execution, streaming liquidity and crypto spot trading and custody services through LMAX Exchange and LMAX Digital. The group is also pushing into unified FX, crypto and stablecoin infrastructure with Omnia Exchange.

TradFi's missing layer

LMAX, whose core foreign exchange business recently recorded its strongest first quarter on record with roughly $50 billion in average daily volume, serves many of the world's largest banks, asset managers and trading firms.

Those markets function because trading activity sits atop a vast network of credit relationships, clearing brokers and prime brokerage arrangements, Mercer says.

"That's what the world's economies and capital markets are built on," he added.

When LMAX launched institutional crypto venue LMAX Digital in 2018, Mercer expected similar infrastructure would quickly emerge in digital assets. Eight years later, he believes its absence remains one of the industry's biggest constraints.

Mercer remains an enthusiastic supporter of blockchain technology, citing instantaneous settlement amd transparent onchain records. But while atomic settlement and delivery-versus-payment transactions are valuable, he argues they are not sufficient for global capital markets.

"The world today is built on leverage and credit, and it will remain so," Mercer says.

The collateral problem

A central challenge is the inability to move collateral efficiently between traditional and digital financial systems.

Today's institutions often operate within separate regulatory and operational environments, with traditional assets, digital assets and stablecoins trapped inside distinct "walled gardens." Collateral cannot move freely between them, reducing capital efficiency and limiting participation.

Market volatility during the first quarter highlighted the issue, Mercer said, as investors rotated between equities, gold and bitcoin in response to macroeconomic uncertainty.

"If you've pre-positioned fiat at a centralized exchange, you can't necessarily deploy that collateral elsewhere when opportunities arise," he said.

"Digital money, whether it's stablecoins or tokenized assets, will ultimately enable much more efficient collateral management."

Achieving that future will require the same types of credit mechanisms that underpin traditional markets today.

Institutions are preparing

In conversations with asset managers this year, only around 20% said they expected to begin trading digital assets directly in the near term, according to Mercer. More than 40%, however, said they were actively studying onchain payments, settlements, collateral management and liquidity management.

Meanwhile, roughly 60% indicated they expect to offer digital asset-related services, while 91% said they are already engaging with stablecoins in some capacity.

"The real inflection point for digital assets won’t be bitcoin's price," he says. "It will be the emergence of a highly efficient collateral layer."

Custody remains another critical hurdle. About three-quarters of institutions Mercer speaks with continue to view secure custody infrastructure as a prerequisite before deploying significant capital.

The challenge is how digital assets become fully interoperable with existing financial systems.

"Ultimately it's about making collateral fungible," Mercer says. "If we get that right, you'll see greater efficiency across all markets, not just digital assets."

For Mercer, the end state is increasingly clear: traditional finance and digital assets converging into a single financial ecosystem, with tokenized money, interoperable collateral and institutional-grade credit infrastructure operating across both worlds.

"The future of capital markets is a fusion of TradFi and digital assets," he says.
