Fiona Boal, Head of Commodities at S&P Dow Jones Indices, thinks commodities will be used as investment vehicles to express things like inflation or the uptick of green technology. She adds cryptocurrencies and blockchain will have an increasing impact on commodities and the use of big data will be become more important for commodity investors as well. She thinks cryptocurrency may be used as an alternative for diversification and inflation protection, particularly against gold. She thinks the tokenization of real assets may revolutionize the way investors can access hard assets, and that digital ledgers will change the way commodities are traded.
