Tokenization Emerges as Structural Upgrade to Finance, Challenging Legacy Settlement Systems

A growing share of global finance is tackling an old problem with a new architecture: despite sleek mobile apps and instant messaging, many capital-market transactions still rely on decades-old ledger systems that keep money and risk tied up for days.

A new Korean-language series draws on the February 2026 book

Tokenization

The authors frame their opening question in practical terms: if consumers can move funds across borders in seconds, why do stock trades often take two business days to fully settle? In the conventional 'T+2 settlement' model, legal finality and the movement of cash and securities lag behind the trade itself, creating a time gap where capital is immobilized and counterparty exposure accumulates.

They contend that today’s “digital finance” frequently masks an older core—mainframes, siloed databases, and multiple intermediaries repeating the same verification steps. In this view, what looks like a modern interface is layered on top of a fragmented back office, leaving markets dependent on reconciliation-heavy processes that were designed for a slower, more localized era of capital flows.

The series points to a high-profile signal from traditional finance: in 2024, BlackRock launched its tokenized fund 'BUIDL' on Ethereum (ETH). CEO Larry Fink described asset tokenization as the next major leap for finance, a message widely read as more than product marketing—an acknowledgement that incumbents are actively exploring a new “operating system” for market infrastructure.

According to the authors, BUIDL surpassed $2.5 billion in assets in a little over a year and captured 44% of the tokenized U.S. Treasury market, underscoring how quickly liquidity can consolidate when investors perceive stronger operational efficiency, clearer collateral utility, or improved access compared with legacy rails.

Crucially, the book argues that tokenization is not simply converting an asset into a number on a screen. Instead, it is the translation of rights and contractual relationships into a distributed-ledger-based digital unit—a 'token'—so that issuance, settlement, and the establishment of collateral can be managed as a single, consistent data 'state' across an asset’s lifecycle.

That shift is described as a move from “separated ledgers” to “shared state.” Under this model, an asset can carry verifiable ownership information and, when conditions are met, trigger payment flows automatically—functioning as an 'intelligent' unit of value rather than a record that must be repeatedly checked after the fact.

The operational implication is a transition from post-trade reconciliation to near-instant finality, where execution and settlement converge. The authors stress that this is not merely about speed; compressing settlement windows can reshape the system’s risk profile by reducing the duration of unsecured exposure and freeing liquidity that would otherwise sit idle during the settlement gap.

As an example of institutional experimentation, the series cites JPMorgan’s blockchain network 'Kinexys', which it says settles more than $2 billion in corporate flows daily on a distributed ledger, enabling around-the-clock liquidity management—an outcome that closed, time-bounded settlement networks have struggled to provide at scale.

The commentary turns pointed when addressing South Korea. Despite world-class IT infrastructure and a dense financial sector, the authors argue that the national debate still often centers on whether tokenization is permitted, rather than what kind of market structure the country aims to build—and who will control the standards, rails, and economics of that structure.

The warning is strategic: if adoption decisions come too late, domestic institutions could find themselves operating as paying users on platforms and protocols designed elsewhere, rather than shaping the rules that govern interoperability, compliance, and data integrity in tokenized markets.

With “the age of ledgers” giving way to “the age of flows,” the series sets up its next installment to examine why major financial powers are elevating tokenization into a national-level agenda and how global regulatory approaches are beginning to converge around shared definitions, custody expectations, and settlement assurances.
