摘要

本文考察了美联储为应对最近的金融危机而建立的新的流动性工具的有效性。我开发了一个基于无套利的带违约风险仿射期限结构模型,并对主要金融机构之间的交易对手违约风险和潜在的抵押贷款违约风险进行了深入的因素分析。本文首先分别考察了新工具在缓解金融机构流动性担忧和降低交易对手风险溢价方面的效果,然后量化了它们在减轻银行间货币市场金融压力方面的总体效果,从而检验了新工具的有效性。;实证结果表明,期限拍卖工具(TAF)主要通过缓解金融机构的流动性担忧,在减轻银行间货币市场的资金压力方面具有很强的作用。宏观经济、金融市场和抵押贷款违约风险的不确定性加剧,显著提高了金融机构之间的交易对手风险溢价,但对其流动性溢价影响甚微。然而,到目前为止,定期证券借贷工具(TSLF)和一级交易商信贷工具(PDCF)在缓解伦敦银行同业拆借利率(Libor)市场的金融压力方面的效果尚不明显。这与市场观察一致,即一级交易商对参与TSLF拍卖的兴趣低于银行对利用TAF的兴趣。

On the Effectiveness of the Federal Reserve's New Liquidity Facilities
This paper examines the effectiveness of the new liquidity facilities that the Federal Reserve established in response to the recent financial crisis. I develop a no-arbitrage based affine term structure model with default risk and conduct a thorough factor analysis of the counterparty default risk among major financial institutions and the underlying mortgage default risk. The new facilities' effectiveness is examined, by first separately examining their effects in relieving financial institutions' liquidity concerns and reducing the counterparty risk premiums, and then quantifying their overall effects in reducing financial strains in the inter-bank money market. ; Empirical results indicate that the Term Auction Facility (TAF) has a strong effect in reducing financial strains in the inter-bank money market, primarily through relieving financial institutions' liquidity concerns. Heightened uncertainty regarding the macroeconomy, financial markets, and mortgage default risk have significantly raised counterparty risk premiums among financial institutions, but have had little effect on their liquidity premiums. The Term Securities Lending Facility (TSLF) and the Primary Dealer Credit Facility (PDCF), however, are found to have had less discernible effects so far in relieving financial strains in the Libor market. This is consistent with market observations of a weaker interest from primary dealers in participating in the TSLF auctions than banks have shown in tapping the TAF.
