Structural Anatomy of an Elite Desk Losing Quarter
Market making is colloquially considered an "infinite money glitch" when retail volumes are abundant and asset prices fluctuate with wide bid-ask bands. However, a decade-long uninterrupted winning streak creates massive structural overhead: proprietary dark-fiber networks, guaranteed exchange connectivity minimums, and premier quantitative compensation.
When macro volatility collapses into a drought (VIX < 13), retail orders dry up while institutional flow becomes fiercely asymmetric and informed. In this environment, spreads contract, inventory carries adverse overnight selection, and fixed operational hurdles wipe out the contracted gross margin.
