Exchanges and Market Structure: Rules and Plumbing — 2026-09-14
Top developments
BSE Technical Glitches Disrupt Sensex Expiry Trading
On September 10, 2026, the Bombay Stock Exchange (BSE) experienced technical difficulties that disrupted futures and options trading during the critical weekly Sensex expiry session. The outage affected specific segments of the cash market and caused issues with price updates and order placements for retail brokerage users, including those on Zerodha. This incident underscores the fragility of exchange infrastructure during peak volatility periods and raises questions about the resilience of clearing mechanisms in emerging markets.
ESMA Highlights Risks in Prediction Markets
The European Securities and Markets Authority (ESMA) published a report on September 11, 2026, emphasizing the risks associated with prediction markets, including insider trading and regulatory loopholes. Despite a monthly volume of €44.8 billion, the regulator warned that these markets remain vulnerable to manipulation and lack the robust oversight seen in traditional financial instruments. This development is critical for EU market participants as it signals potential future regulatory tightening on alternative asset classes.
Crypto Exchange Reliability Concerns Mount
Data released around September 7, 2026, revealed that nine monitored crypto exchange status pages logged 136 disruptions between August 1 and September 7. Of these incidents, 14 suspensions remained unresolved, primarily affecting deposits and withdrawals. This high frequency of outages highlights ongoing infrastructure challenges in the digital asset sector, which may influence regulatory attitudes toward stablecoin and exchange operational standards.
Local view
In Germany, local media is focusing on the regulatory status of prediction markets following ESMA's recent warnings. Coin-Update.de reports that while ESMA views EU licensing as mandatory for providers, the legal status for users and held assets remains ambiguous in Germany. This uncertainty is causing caution among local stakeholders who are navigating the intersection of traditional financial regulations and new market structures.
Context & numbers
- Prediction Market Volume: ESMA cited a monthly volume of €44.8 billion in prediction markets, underscoring the scale of this unregulated or lightly regulated segment.
- Crypto Outage Frequency: 136 incidents were recorded across nine major crypto exchanges in a 38-day period ending September 7, 2026, with nearly half affecting deposits and withdrawals.
On the radar
- Post-Glitch Investigations: Market participants are watching for official SEBI (Securities and Exchange Board of India) statements regarding the BSE technical glitches on September 10, particularly any proposed changes to expiry-day protocols.
- ESMA Follow-up on Prediction Markets: Stakeholders anticipate further guidance from ESMA on how national competent authorities should enforce existing rules against prediction market operators, given the identified insider trading risks.
