利率衍生品回顾与展望：详解国债期货套利策略之期现策略

Group 1: Arbitrage Strategy Overview - The term "IRR" refers to the Implied Repo Rate, which indicates the theoretical annualized return from buying cash bonds and shorting futures for delivery[12] - The two main arbitrage strategies are "positive arbitrage" (shorting futures while buying cash bonds) and "negative arbitrage" (going long on futures while shorting cash bonds)[11] - Positive arbitrage is considered to have a near risk-free nature, and it is compared with high-grade interbank deposit yields[13] Group 2: Performance and Backtesting - In the first half of 2025, there were periods of high positive arbitrage yields, particularly for the TS2506 and TF2506 contracts, with IRR values of 2.20% and 2.05% respectively[18][25] - Backtesting results show that constructing a positive arbitrage strategy for TS2506 yielded higher returns than holding cash bonds until delivery, while TF2506 underperformed compared to directly holding 5-year cash bonds[26] - The IRR for the T2312 contract was 3.93% on October 31, 2023, significantly higher than the 1-month deposit yield of 2.50%[17] Group 3: Market Outlook and Recommendations - The market is expected to remain volatile, with a focus on the TL2603 contract for shorting basis opportunities as it approaches delivery[4] - The IRS strategy shows limited upside potential, while interbank deposits are considered to have better value[5] - Current IRR levels for various contracts are fluctuating, with T2603's IRR ranging from 1.13% to 1.76%, indicating no significant advantage over 3-month interbank deposit rates[73]
