The question of whether decentralized technology will replace traditional banks has been a central debate in the crypto-finance world. Lux Thiagarajah, Chief Commercial Officer at Openpayd and a former executive at JPMorgan Chase and HSBC, offers a clear verdict: this is not a replacement but a “re-platforming.” Regulated entities will remain essential because governments will not outsource prudential oversight to permissionless systems.
From Revolution to Infrastructure
For years, the promise of blockchain in finance was draped in revolutionary language. Yet as early 2026 unfolds, institutional adoption is proving far more pragmatic. Thiagarajah notes that the real disruption is not happening in front-end billing but in the backend “plumbing.” With the full implementation of the European Union’s Markets in Crypto-Assets (MiCA) regulation and the 2025 enactment of the U.S. GENIUS Act, stablecoins have evolved from experimental “wallet-based” tokens into regulated “account-based” production tools.
“The strongest institutional buy-in remains in the on- and off-ramp space,” Thiagarajah said. “These rails are the critical bridge between traditional fiat systems and blockchain networks.” While the industry once dreamed of programmable invoices as NFTs, institutions now prioritize settlement velocity. By embedding stablecoins into their backend operations, companies reduce settlement times from days to seconds. However, the “last mile”—converting digital value back into fiat—remains a high-demand capability.
The Re-Platforming of Giants
Thiagarajah dismissed the idea that decentralized tech is destined to replace legacy systems. He points to major financial institutions—JPMorgan’s Kinexys and BlackRock’s BUIDL fund—as evidence of “re-platforming” rather than displacement. “This is not decentralization displacing banks,” he stated. “It is banks integrating decentralized technology into their existing models. KYC, AML, and prudential oversight are not optional, and governments will not outsource those responsibilities to fully permissionless systems.”
A critical challenge emerges from regulatory divergence. The EU’s MiCA framework emphasizes strict state-directed supervisory control, while the U.S. GENIUS Act focuses on federal legal protections and separation of banking and commerce. This raises a key question for global treasurers: Will businesses need to maintain separate, isolated on-chain stacks for each jurisdiction? Thiagarajah believes the answer lies in architecture. “The underlying technology is not fragmented. Blockchains, wallets, and smart contract logic remain aligned. If infrastructure is built around a single core ledger, with compliance logic applied at the asset layer rather than the chain layer, we can avoid creating multiple isolated environments.” The real risk, he warns, is not the rules themselves but a lack of interoperability. If liquidity in the Eurozone is locked in MiCA-compliant tokens while U.S. liquidity sits in GENIUS-compliant tokens, the cost of moving money across borders could remain high despite technological leaps.
The End of the Batch-Based Era
Looking ahead 10 years, Thiagarajah predicts that while banks as regulated entities will survive, the “legacy constructs” defining them—batch-based settlement and multi-day processes—will vanish. As CCO of Openpayd, his role is to position the firm as the architect of this bridge phase. By providing universal infrastructure connecting domestic fiat rails with blockchain networks, Openpayd enables institutions to scale their digital asset strategies without waiting for a full overhaul of global business accounting.
On MiCA’s strict transaction caps on U.S. dollar-denominated stablecoins within the European Economic Area, Thiagarajah argued that despite aiming to protect the euro, such requirements risk creating significant friction for European businesses. Companies may have to “take the long way round” to settle transactions, while forced conversions of euro-backed tokens into dollars for international goods and services could raise foreign exchange costs. He asserts that unless there is a massive structural shift in the dollar’s role as the global reserve currency, the market will remain fundamentally dollar-denominated for the foreseeable future.
Thiagarajah rejects the notion that regulation inherently stifles growth. Instead, he posits that regulatory transparency is the missing ingredient that finally justifies Tier 1 institutional flows. For banks and funds, “unclear” is synonymous with “uninvestable.” Laws like MiCA and the GENIUS Act provide the formal permission these institutions need to move from pilots to massive liquidity deployment.
