Wintermute USA, a New York-based subsidiary of the London market maker, has formally registered as a broker-dealer with the SEC and FINRA, granting it authority to trade equities, options, and crypto ETFs in a regulated capacity. This marks a significant expansion of Wintermute's U.S. footprint beyond OTC crypto into traditional regulated securities markets, placing it alongside firms like Jane Street and Jump in straddling both worlds.
For Armada's crypto desk, Wintermute is already a known liquidity provider in digital asset markets. Its regulated BD status raises its counterparty credibility and could make it a viable repo counterparty for ETF-wrapped crypto collateral. Armada should track whether Wintermute begins participating in FICC-cleared or bilateral repo involving crypto ETF shares.
