国债期货跨期价差系列专题五：基于 LSTM 的时序预测与策略改进研究 广发期货研究所 电 话：020-88818009 E-Mail：zhangxiaozhen@gf.com.cn 摘要： 在前两篇研究系统梳理国债期货跨期价差的定价逻辑及多因 子量化套利方法的基础上，本文进一步引入时序建模框架，重点考 察在既有基本面因子体系下，显式纳入时间维度信息是否能够提升 跨期价差走势的预测能力与策略表现。具体而言，本文构建了基于 长短期记忆网络（LSTM）的跨期价差方向预测模型，以净基差、 IRR、资金利率等核心因子作为输入，并以跨期价差涨跌方向作为 监督信号进行二分类建模。模型训练阶段使用全部国债期货合约样 本，2024 年及以前的数据作为训练集，2025 年数据作为严格样本 外测试集。 预测结果显示，LSTM 模型在 TS、T、TF 三个品种上的样本 外二分类准确率分别为 54.11%、53.67% 和 56.28%。进一步回测 表明，在 T 与 TF 品种上，LSTM 模型的样本外收益风险特征优 于 DNN，其中 T 合约的年化收益率为 6.83%，夏普比率为 1.70， TF 合约的年化收益率为 7.63%，夏 ...

Report Summary Core View - There are both positive and negative factors in the bond market. Positive factors include a loose capital market despite the contraction of the manufacturing PMI, and rumors of "dual cuts" in the political situation boosting sentiment, leading to a decline in yields and an overall rise in futures.

1. Report Industry Investment Rating - There is no information about the report industry investment rating in the provided content. 2. Core View of the Report - The report analyzes the factors affecting the bond market.

Monetary easing may pick up in October after the economic recovery in the third quarter becomes clear, tariff negotiations conclude, and the Fed cuts interest rates [11][12]. - The bond market is currently constrained by funds. The money market rate has bottomed out and is facing upward pressure during the July tax - payment month, and the short - term rate restricts the decline of the long - term rate [12]. Market Conditions Bond Futures - On July 16, most Treasury bond futures contracts declined slightly.

Interest - rate Bonds - The yields of major inter - bank interest - rate bonds showed a pattern of short - term decline and long - term increase, with a change of less than 1bp.

Money Market - The central bank actively offset the tax - period disturbances, and the money market remained stable. There were 755 billion yuan of reverse repurchase maturities, and the central bank conducted 520.1 billion yuan of reverse repurchase operations [10]. - The inter - bank money market sentiment index slightly rebounded, and short - term money market rates declined. The overnight weighted rate of inter - bank deposits fell 6.1bp to 1.47%, and the 7 - day rate fell 4.1bp to around 1.53%. The medium - and long - term funds were stable and loose, and the 1 - year AAA certificate of deposit rate remained stable around 1.62 - 1.63% [10]. Industry News - Wang Huning emphasized the importance of comprehensively expanding domestic demand at a symposium, and relevant research results need to be deepened and applied [13]. - The "old - for - new" housing policy has been implemented in multiple cities, which is expected to boost the real estate market [13]. - Trump announced a 30% tariff on EU imports starting from August 1, which may escalate trans - Atlantic trade conflicts [14]. - The US Trade Representative's Office launched a 301 investigation into Brazil's unfair trade practices [14]. - Fed's Logan said that the Fed needs to maintain high interest rates for a longer time to control inflation, and tariff hikes may cause additional inflationary pressure [14].
