Chainlink and Euroclear Partner to Solve Corporate Action Problem Across $46 Trillion in Custody

Euroclear, one of the world’s leading financial market infrastructure providers with €40.7 trillion in assets under custody, has partnered with Chainlink to address the corporate actions problem

Corporate actions, the processes by which companies distribute dividends, execute stock splits, manage rights issues, and handle other ownership-affecting events, cost the global financial system more than $58 billion every year in errors, reconciliation failures, and operational overhead. That number has persisted for decades because the underlying infrastructure handling these events was never designed for the scale and complexity of modern capital markets.

What Corporate Actions Actually Are

A corporate action is any event initiated by a company that affects its shareholders or bondholders. Dividend payments, mergers, tender offers, bond maturities, stock splits

Every one of these requires financial institutions to talk to each other, update records across separate systems, and make sure the right value lands with the right people at the right time.

The systems doing that work were not built for each other. Different custodians, brokers, and market participants keep their own records, and reconciling those records requires manual processes that are slow and prone to mistakes. Data passes through intermediary after intermediary. Each handoff is a chance for something to go wrong.

By the time a dividend payment reaches the end investor, it has passed through enough hands that mistakes are common and expensive to fix.

The $58 billion annual cost reflects not just the direct cost of errors but the operational overhead of the reconciliation processes that exist to catch and correct them. It is one of the most persistent inefficiencies in traditional finance, and it has remained persistent because fixing it requires coordination across an entire ecosystem of institutions rather than a single company making a unilateral technology decision.

What Euroclear Brings to This Problem

Euroclear is not a peripheral player in this space. With €40.7 trillion, equivalent to more than $46 trillion, in assets under custody, it sits at the center of European and global securities settlement. It processes domestic and cross-border securities transactions and fund settlements for a client base that spans banks, broker-dealers, central banks, and asset managers across more than 90 countries.

Its position in the market means that what Euroclear implements tends to propagate through the institutions that connect to it. A solution to the corporate actions problem that runs through Euroclear’s infrastructure reaches a significant portion of global securities activity rather than operating at the margins of the market.

What Chainlink Provides

Chainlink describes itself as a leading oracle platform that has enabled $28 trillion in transactions by connecting real-world data and systems to blockchain infrastructure.

Chainlink handles data delivery, cross-chain interoperability, compliance, privacy, and orchestration of complex processes across different systems. For corporate actions specifically, it makes those events machine-readable, verifiable, and automatically executable. Instead of manual data entry at every step of the chain, Chainlink’s oracle infrastructure delivers verified corporate action data directly to the systems that need to act on it. Settlement updates automatically. The intermediary steps that cause errors don’t happen.

Put Chainlink’s verification and orchestration together with Euroclear’s central position in securities custody and you have the conditions to automate something the industry has been failing to automate for decades.

Why This Matters Beyond the Two Companies

The Euroclear and Chainlink collaboration is a direct example of what the financial industry calls the tokenization and automation of traditional finance workflows. The $58 billion corporate actions problem is not unique in kind. It is one of several large-scale inefficiencies in traditional finance that persist because they require coordinated infrastructure changes across many institutions simultaneously.

When Euroclear adopts an infrastructure standard, the institutions connected to its network have a practical reason to follow. That’s what makes this more than a technology partnership.

Conclusion

The $58 billion corporate actions problem has existed for decades because fixing it requires infrastructure coordination at scale, not just a better tool at one institution

Euroclear’s position at the center of global securities custody and Chainlink’s automation and data verification infrastructure address both sides of that requirement. If it works at Euroclear’s scale, the implications for how corporate actions are processed globally are hard to overstate.
