Annual rebalancing of the S&P GSCI index provides a novel and strong identification to estimate the shape of supply curves for commodity futures contracts. Using the 24 commodities included in the S&P GSCI for 2004–2017, we show that cumulative abnormal returns (CARs) reach a peak of 59 basis...

The increasing inflow of institutional investors replicating broad based indices into commodity futures markets has been linked to excessive calendar spreads and anomalies in futures curves.
