iShares Bloomberg Enhanced Roll Yield Commodity Swap UCITS ETF (ROLG.L) is an exchange-traded fund that seeks to track the performance of the Bloomberg Enhanced Roll Yield Total Return Index, providing indirect exposure to a diversified basket of commodities through unfunded total return swaps; the index employs a rules-based strategy selecting three to four futures contracts per commodity across energy, agriculture, metals, and other sectors, rolling monthly over ten business days to optimize roll yield and minimize contango effects. The ETF offers accumulation share classes in USD (ROLL) and GBP (ROLG), with an ongoing charge of 0.28%, and is listed on the London Stock Exchange and Bolsa Mexicana de Valores. Launched on September 28, 2018, it is domiciled in Ireland as part of iShares VI plc, issued by BlackRock, with headquarters in Dublin, Ireland, and available for sale in Europe, the United Kingdom, Mexico, and Saudi Arabia. The fund's single holding is a total return swap on the benchmark index, representing 100% of assets under management, which stood at approximately 840 million GBP for the GBP share class as of recent data. In February 2022, the benchmark transitioned from the Bloomberg Roll Select Commodity Index to the Bloomberg Enhanced Roll Yield Total Return Index to improve performance optimization; no further major partnerships, acquisitions, funding rounds, product launches, or strategic shifts have been reported in the last 1-2 years.
