Pre-Trade Transparency
Pre-trade transparency means that bid and ask prices are publicly displayed before trades occur, allowing investors to see what prices are available before deciding to transact. U.S. exchange markets provide significant pre-trade transparency through the SIP (Securities Information Processor) which distributes consolidated quotes. However, a large fraction of trades occur off exchanges in less transparent environments.
Post-Trade Transparency
Post-trade transparency means that completed trades are promptly reported to the public. SEC rules require reporting of OTC equity trades to FINRA TRFs within 10 seconds of execution. This post-trade transparency is generally considered adequate for U.S. equity markets, though Treasury market transparency has been an area of ongoing regulatory focus.
Operational Transparency
Operational transparency — understanding how market makers and brokers actually make decisions about order routing and execution — is where the current framework has the most gaps. PFOF arrangements, the economics of market-making, and the algorithms used to price retail orders are largely opaque to retail investors. Rule 606 and 605 provide some transparency, but not complete visibility into operational decision-making.
Transparency as Investor Protection
The fundamental purpose of financial market transparency requirements is investor protection: ensuring that investors can make informed decisions and that bad actors cannot exploit information asymmetries. In The Ethics Reporter's view, the current framework — with its significant gaps in operational transparency — does not fully serve this purpose for retail investors. Regulatory reform that increases transparency is, in our view, in the public interest.
