So how can they do this? The Fed will finance a special purpose vehicle (SPV) for each acronym to conduct these operations. The Treasury, using the Exchange Stabilization Fund, will make an equity investment in each SPV and be in a "first loss" position. What does this mean? In essence, the Treasury, not the Fed, is buying all these securities and backstopping of loans; the Fed is acting as banker and providing financing. The Fed hired BlackRock Inc. to purchase these securities and handle the administration of the SPVs on behalf of the owner, the Treasury.
