These reports collect information on market activity from primary dealers in U.S. government securities. This family of reports consists of the Weekly Report of Dealer Positions (FR 2004A), the Weekly Report of Cumulative Dealer Transactions (FR 2004B), the Weekly Report of Dealer Financing and Fails (FR 2004C), the Weekly Report of Specific Issues (FR 2004SI), the Daily Report of Specific Issues (FR 2004SD), and the Daily Report of Dealer Activity in Treasury Financing (FR 2004WI). The FR 2004A collects weekly data on dealers' outright positions in Treasury and other marketable debt securities. The FR 2004B collects cumulative weekly data on the volume of transactions made by dealers in the same instruments for which positions are reported on the FR 2004A. The FR 2004C collects weekly data on the amounts of dealer financing and fails. The FR 2004SI collects weekly data on outright, financing, and fails positions in current or on-the-run issues. Under certain circumstances this information is also collected on a daily basis on the FR 2004SD for on-the-run and off-the-run securities. The FR 2004WI collects daily data on positions in to-be-issued Treasury coupon securities, mainly the trading on a when-issued delivery basis.
