Wall Street is extending trading hours faster than the plumbing that settles the trades. CME opened its crypto derivatives markets on weekends in May while keeping clearing and settlement on a business-day schedule, and DTCC's NSCC trade processing has run 24 hours a day, five days a week since June 28. What the new hours expose was visible in June, when a participant's erroneous trades forced DTCC subsidiaries to postpone a day of securities settlement, leaving cash stuck in a Fed account and draining bank reserves. Chicago Fed researcher David DeCarlo's analysis of CME disclosures puts the median single-participant payment obligation at $3.73 billion, and $24.31 billion under severe but plausible stress.
Why it matters
Someone has to supply cash when the wholesale payment systems are closed. DTCC's multilateral netting cuts equity payment obligations by an average of 98%, but the roughly 2% that remains still has to move on business days, so weekend trading and stablecoin redemptions force institutions to fund payments in advance. Circle keeps cash ready at partner banks to offer around-the-clock near-real-time redemptions, deliberately giving up Treasury yield to do it.
The June disruption showed the mechanics. Cash accumulated in the central counterparty's account at the Fed, where banks could not draw on it, and reserves fell until settlement sent it back. The Chicago Fed's Cindy Hull credited two factors for short-term rates holding steady: market participants trusted the payments would arrive, and the banking system had enough reserves to absorb the temporary drop.
Market impact
The Fed's approved expansion adds Sundays and weekday holidays to Fedwire no earlier than 2028, and FedNow's $10 million transaction limit remains well below what clearing firms need to move. Meanwhile, OKXICE, the joint venture between OKX and the NYSE owner, launches round-the-clock trading in more than 70 tokenized securities on Nov. 23 under a temporary SEC exemption, with the banking and redemption timing still open.
The CFTC's May 29 advisory spells out what continuous trading demands: staffed operations and risk teams, disruption playbooks, and after-hours authority to release a replacement payment before the usual rails reopen. Watch how clearing houses size weekend guaranty-fund surcharges as volume builds.
Frequently asked questions
-
Why did bank reserves fall during the June DTCC settlement delay?
Cash accumulated in the central counterparty's account at the Fed while settlement was postponed, leaving it in an account banks could not draw on. Rates held steady because reserves were ample and participants trusted the payments would arrive.
-
How much does DTCC's multilateral netting reduce payment obligations?
DTCC reports an average 98% reduction in equity payment obligations. That leaves roughly $2 payable per $100 of obligations, but those remaining payments still move on business-day settlement schedules.
-
How does CME handle settlement for weekend crypto derivatives trades?
Trades made from Friday evening through Sunday evening are booked for the next business day, when clearing and settlement are processed. Members supporting weekend contracts also pay a surcharge into the guaranty fund.
-
How does Circle offer around-the-clock stablecoin redemptions?
Circle keeps cash ready at partner banks with arrangements to move it when customers need it, allowing near-real-time redemption for qualified customers. Because that cash earns less than Treasuries, Circle gives up interest to offer the speed.
-
When will Fedwire run on weekends?
The Federal Reserve's approved expansion adds Sundays and weekday holidays to Fedwire Funds and the National Settlement Service no earlier than 2028. FedNow already runs weekends, but its $10 million transaction limit is well below clearing-firm needs.
