🚫 Jane Street Banned: India's Billion-Dollar Market Shake-Up
In a move that has rocked algorithmic and institutional trading circles, India has effectively banned Jane Street — one of the world’s most aggressive proprietary trading firms — from executing certain trades on its exchanges.
This decision could wipe out billions in high-frequency liquidity from the Indian markets. But could this be an unexpected tailwind for domestic players like BSE, Nuvama, and emerging algorithmic platforms? Let’s break it down.
💥 What Happened?
Jane Street — along with affiliates — reportedly ran afoul of SEBI’s algo trading rules, triggering a clampdown. This includes limitations on:
Proprietary arbitrage algorithms
High-frequency cross-border trades
Potential latency arbitrage techniques across BSE and NSE
📉 Market Impact
📊 Volume Crunch
Jane Street accounted for 5%–7% of daily equity derivatives volumes, as per Vizzve’s Q2 Algo Snapshot.
NSE Derivatives Volumes: Down 4.2% WoW post-ban
BSE Cash Segment: Slight uptick as volumes shift
VIX Volatility Index: Up 7.4% in the 48 hours following the restriction
📈 The Winners?
🏛️ BSE
As a low-latency trading venue, BSE could attract firms looking to fill the void. It saw:
22% rise in options turnover (weekly)
18% jump in SME segment participation
📉 Nuvama (Formerly Edelweiss Securities)
With a growing presence in institutional algo execution, Nuvama is reportedly fielding increased interest from global funds looking for compliant arbitrage routes.
"The exit of one player creates room for 5. It’s now about agility and compliance," says Ravi Rathi, strategist at Vizzve Financial.
