Market Structure

Efficient, transparent, and resilient markets are the foundation of economic growth. SIFMA engages with regulators, policymakers, and market participants to strengthen how markets are designed and function—from trading and clearing to capital formation and private markets.

Across equities, fixed income, and derivatives, we advocate for balanced reforms that enhance liquidity, protect investors, and sustain U.S. leadership in global finance. Our work ensures the capital markets remain deep, competitive, and adaptable to innovation.
