The Future of Trading

Regulatory Shifts and Market Structure in Derivatives

• The CFTC and CME Group are overseeing a significant migration from unregulated bilateral swaps to exchange-traded futures, a process termed the "futurization" of swaps.
• Bart Chilton (CFTC Commissioner) asserts that futures markets were not the cause of the 2008 financial meltdown, citing CME and ICE as effective stabilizers.
• New regulations, specifically under Dodd-Frank, mandate capital and margin requirements to back transactions, addressing the excessive leverage (e.g., Lehman Brothers' 30:1 ratio) seen pre-crisis.
• The CFTC aims to establish Swaps Execution Facilities (SEFs) to increase competition and transparency, though Chilton notes internal delays in finalizing these rules.
• Terry Duffy (CME Group) argues that government mandates were less effective than economic incentives for moving business to clearinghouses, but acknowledges the necessity of clearing to manage systemic risk.
• Duffy highlights that CME holds a "vertical silo" structure with 98% of the US listed futures market, contrasting with the fragmented equity market.
• Chilton emphasizes the need for faster rule implementation, noting that since July, the CFTC has completed only 3% of its remaining rules due to lobbying, litigation risks, and underfunding.

The Role and Impact of High-Frequency Trading (HFT)

• Panelists refer to high-frequency traders (HFT) as "cheetahs," noting they operate 24/7, 365 days a year, seeking micro-profits in milliseconds.
• Jamil Nazarali (Citadel) defends HFT as necessary market lubrication that provides liquidity, lowers costs, and improves transparency for retail investors.
• Lou Salkind (DE Shaw) presents data indicating bid-ask spreads are roughly one-fifth of their value a decade ago, and commissions have dropped from 1% to cents per share.
• Chilton raises concerns that proprietary HFT firms trading for their own books profit more when interacting with retail traders ($3.49 on average $50,000 trades) compared to institutional traders.
• Chilton advocates for mandatory registration of proprietary HFT firms to improve surveillance, as currently, they are not registered and their books are hard to access without a subpoena.
• Duffy points out that HFT volume in futures is decreasing because the market's efficiency leaves little arbitrage opportunity, whereas fragmentation in equities sustains HFT volume.
• The panel discusses the "Twitter hack" incident where the S&P 500 dropped 18 points; Duffy argues circuit breakers prevented a larger crash, a mechanism he notes was absent in the 2012 "Flash Crash" in equities.

Equity Market Fragmentation and Transparency

• Approximately 40% of US equity trading occurs off-exchange in dark pools, raising concerns among panelists regarding fair access and transparency.
• Jamil Nazarali supports the competition driven by fragmentation but warns that off-exchange venues lack the same "fair and open access" requirements as lit exchanges.
• Lou Salkind argues that fragmentation has broken the historical NYSE/NASDAQ duopoly, resulting in deeper liquidity and better execution prices through cross-market arbitrage.
• Terry Duffy contrasts the equity market's fragmentation with the futures market's centralization, arguing that fragmentation creates opportunities for HFT to exploit price differences across venues.
• Duffy notes that the equities market lacks the robust circuit breakers and limit-up/limit-down mechanisms standard in the futures market, citing the Accenture "penny stock" anomaly during the Flash Crash.
• The panel acknowledges a perception problem where terms like "dark pool" and "hedge funds" deter retail investor participation, despite data showing improved trading conditions.

International Harmonization and Future Outlook

• Bart Chilton identifies the harmonization of global regulations as a major challenge to prevent regulatory arbitrage, where capital might migrate to jurisdictions with thinner rulebooks.
• Chilton predicts that if the US and EU establish harmonized rules, the rest of the world will follow, citing the "field of dreams" principle in financial regulation.
• Lou Salkind anticipates an increase in cross-asset class arbitrage as electronic dissemination of price and size becomes real-time across asset classes.
• The group discusses the emergence of big data in trading, including the use of satellite imagery to forecast earnings and aggregating social media signals (e.g., Twitter) for trading momentum.
• Chilton warns that regulatory "analysis paralysis" and insufficient funding may cause the CFTC to over-correct or fail to implement necessary reforms in a timely manner.
• Terry Duffy concludes that maintaining participant confidence is paramount, requiring exchanges to invest heavily in surveillance (e.g., Citadel spends $40 million annually) and compliance.
