The Department of the Treasury, specifically the Bureau of the Fiscal Service, intends to award a sole source contract to the London Stock Exchange Group PLC for exclusive access to the SEDOL Masterfile data, which is critical for the Office of Financial Research (OFR) and the Financial Stability Oversight Council (FSOC). This procurement is necessary to fulfill the mandates of the Dodd-Frank Wall Street Reform and Consumer Protection Act, which requires these entities to monitor financial stability and assess risks within the U.S. financial system. The SEDOL Masterfile is uniquely provided by LSEG, and no other vendors can supply this essential dataset, reinforcing the necessity of this sole source contract. Interested parties must submit their written responses by 10:00 a.m. EST on November 4, 2024, to purchasing@fiscal.treasury.gov, including company details and a capabilities statement, as no solicitation is available for this opportunity.
