Bank Funding Risks, Risk Aversion, and the Choice of Futures Hedging Instrument
提出一个银行行为的企业理论模型，分析银行在不确定未来CD利率和数量时，如何选择最优期货对冲策略，并比较CD期货与国债期货在1981-1983年的表现。
ABSTRACT Currently, theories of financial futures hedging are based on either a portfolio‐choice approach or a duration approach. This article presents an alternative: a firm‐theoretic model of bank behavior with financial futures. Assuming the bank is uncertain about cash CD interest rates and the quantity of CDs it needs in the future, expressions for the optimal futures hedge are derived under constant absolute risk aversion and constant relative risk aversion. The performance of these two strategies is estimated from 1981–1983 using either the recently developed CD futures contract or the T‐Bill futures contract. These results are also compared with the performance of a portfolio‐choice strategy and a routine hedging strategy. The analysis indicates that the CD futures market can serve a hedging purpose that is not served by the previously established T‐Bill futures market.
