Euroclear, one of the world’s leading providers of financial market infrastructure with €40.7 trillion in assets under custody, has partnered with Chainlink to tackle the problem of corporate actions.
Corporate actions, the processes by which companies pay dividends, conduct stock splits, manage rights issues and handle other ownership-impacting events, cost the global financial system more than $58 billion annually in errors, failed reconciliations and operational overhead. That number will persist for decades because the underlying infrastructure that handles these events was never designed for the scale and complexity of modern capital markets.
Euroclear has €40.7 trillion ($46+ trillion) in assets under custody.
Together with Chainlink, Euroclear solves the annual problem of corporate actions exceeding $58 billion.

What corporate actions actually are
A corporate action is any event initiated by a company that affects its shareholders or bondholders. Dividend payments, mergers, bids, bond maturities, stock splits.
All of this requires financial institutions to talk to each other, update data in separate systems, and ensure that the right value gets to the right people at the right time.
The systems that do that work are not built for each other. Different custodians, brokers, and market participants maintain their own data, and reconciling that data requires manual processes that are slow and prone to errors. Data passes through intermediary after intermediary. Every transfer is an opportunity 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 only the direct costs of errors, but also the operational overhead of the reconciliation processes that exist to detect and correct them. It is one of the most persistent inefficiencies in traditional finance, and it has remained persistent because solving it requires coordination across an entire ecosystem of institutions rather than a single company making a unilateral technology decision.
What Euroclear adds to this problem
Euroclear is not a peripheral player in this area. With €40.7 trillion, equivalent to over $46 trillion, in assets under custody, it is 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 includes banks, broker-dealers, central banks and asset managers in more than 90 countries.
Its position in the market means that what Euroclear implements tends to spread through the institutions associated with it. A solution to the corporate actions problem running through Euroclear’s infrastructure reaches a significant portion of global securities activity rather than operating at the margins of the market.
What Chainlink offers
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 ensures data delivery, cross-chain interoperability, compliance, privacy and orchestration of complex processes across different systems. Specific to business actions, it makes these events machine-readable, verifiable, and automatically executable. Instead of manual data entry at each step of the chain, Chainlink’s Oracle infrastructure delivers verified business action data directly to the systems that need to respond. The settlement will be updated automatically. The intermediate steps that cause errors do not happen.
Combine Chainlink’s verification and orchestration with Euroclear’s central position in securities custody and you have the conditions to automate something the industry has been unable to automate for decades.
Why this matters beyond the two companies
The collaboration between Euroclear and Chainlink is a direct example of what the financial industry calls the tokenization and automation of traditional financial workflows. The $58 billion corporate action problem is not unique in nature. It is one of many large-scale inefficiencies in traditional finance that persist because they require coordinated changes in the infrastructure of many institutions at once.
When Euroclear adopts an infrastructure standard, the institutions connected to its network have a practical reason to follow. That makes this more than a technology partnership.
Conclusion
The $58 billion corporate action problem has existed for decades because solving it requires infrastructure coordination at scale, not just a better tool from one institution.
Euroclear’s position at the center of global securities custody and Chainlink’s automation and data verification infrastructure meet both sides of this demand. If it works on the scale of Euroclear, the implications for the way corporate actions are processed globally are difficult to overstate.
