Coinbase forces institutional clients into Deribit migration by 9 September
Coinbase will fold its International Exchange into Deribit on 9 September, requiring institutions to rebuild API access and margin lines.
Coinbase has set 9 September as the date it will fold its institutional International Exchange (INTX) business into Deribit, the derivatives venue it acquired for roughly $2.9 billion last year. The move will force institutional clients to close positions, migrate accounts and rebuild their technical infrastructure within weeks, marking the operational conclusion of Coinbase’s push to consolidate its global derivatives offering under a single brand.
Under the plan, Coinbase will cancel all open INTX orders on the migration date, settle existing positions at Deribit’s mark price, crystallise profit and loss, and transfer the resulting balances into newly created Deribit subaccounts. Positions will then be recreated through matched “Migration” block trades, which Coinbase describes as administrative entries rather than new client-initiated trades. Trading is expected to pause for roughly 30 minutes during the cutover.
A hard deadline and a pricing gap risk
Institutions that do not wish to be migrated face a firm cut-off: positions and accounts must be closed before 28 August, after which any account left open will be treated as having accepted the new terms and the transfer itself. Coinbase has said it will provision Deribit subaccounts in a read-only state from 31 August, giving clients a short window to verify account mappings, test connectivity and generate new API credentials before live trading resumes.
Because International Exchange and Deribit will continue pricing and settling independently right up until the cutover, Coinbase has flagged that any divergence between the two venues’ markets could produce immediate unrealised gains or losses once Deribit reopens. The exchange has been explicit that such swings would reflect a price gap accumulated during the downtime rather than a migration fee or a realised loss, and it has confirmed no trading or settlement charges will apply to the transfer itself.
API keys and margin loans do not carry over
Existing International Exchange API keys will stop functioning on Deribit, meaning institutional trading desks must generate fresh credentials and reroute their endpoints before resuming activity. Margin loans will also fail to transfer automatically, requiring clients to arrange new financing terms ahead of the switch — a detail likely to concern treasury and risk teams accustomed to continuous credit lines with Coinbase.
For an audience of institutional allocators, the migration underscores how quickly counterparty infrastructure can change following a major acquisition, even when the underlying strategic rationale — consolidating liquidity onto the world’s largest crypto options venue by volume and open interest — is sound. Coinbase completed its purchase of Deribit in August 2025, and the September cutover effectively retires the International Exchange brand as a standalone institutional derivatives platform.
The episode illustrates a broader theme in institutional crypto market structure: as exchanges pursue scale through acquisition, clients increasingly bear the operational burden of migration, from re-authenticating API access to managing pricing discontinuities across venues during transition windows. For firms with material derivatives exposure, the coming weeks will require careful coordination between compliance, treasury and technology teams to avoid disruption when trading resumes on Deribit.
