商品库存是剖析货币政策在商品市场传导机制的关键切入点。本文尝试借助库存理论的供求均衡(而非无套利均衡)分析框架来重构货币政策下的商品价格“超调模型”。理论分析发现:货币政策的直接效应是通过市场利率调整资金占用成本,间接效应则是改变市场库存均衡点,进而影响商品价格预期变动;扩张性货币政策易引发商品价格超调,而紧缩性货币政策却易导致商品价格调整不足。其后,通过期货市场风险供求均衡思路将风险溢价理论和库存理论有机结合起来,由期货基差变动验证货币政策在商品市场的传导机理,为理论检验提供实证框架。将理论模型运用于上海期货交易所有色金属合约,发现实证结论很好地支持了相关理论分析。
商品庫存是剖析貨幣政策在商品市場傳導機製的關鍵切入點。本文嘗試藉助庫存理論的供求均衡(而非無套利均衡)分析框架來重構貨幣政策下的商品價格“超調模型”。理論分析髮現:貨幣政策的直接效應是通過市場利率調整資金佔用成本,間接效應則是改變市場庫存均衡點,進而影響商品價格預期變動;擴張性貨幣政策易引髮商品價格超調,而緊縮性貨幣政策卻易導緻商品價格調整不足。其後,通過期貨市場風險供求均衡思路將風險溢價理論和庫存理論有機結閤起來,由期貨基差變動驗證貨幣政策在商品市場的傳導機理,為理論檢驗提供實證框架。將理論模型運用于上海期貨交易所有色金屬閤約,髮現實證結論很好地支持瞭相關理論分析。

Commodity Storage is key point of view to analyze the effects of monetary policy on price dynamics. The theory of Storage will be adopted to reconstruct Frankel's Overshooting Model, which is basic analysis framework of effects of monetary policy on commodity price. Theoretical analysis finds that, ( 1 ) direct effect of monetary policy adjusts market interest, and indirect effects on convenience yields and marginal risk aversion cost, both effects push the supply curve of storage, make market equilibrium moving, and finally have influence on the expectation of commodity price change; (2) commodity price goes up and overshoots under excess liquidity, whereas commodity price goes down and undershoots for convenience yield under tighten liquidity; and monetary policy impresses asymmetric influences on price dynamics of commodity. Empirical framework based on future market will be constructed by incorporating risk premium theory into the model of storage, and empirical study from SHFE finds that theoretical results are supported perfectly.
