Thus far agriculture is outperforming everything on a year-to-date basis. The chart below plots PowerShares DB Agriculture Fund (ARCA:DBA), an ETF tracking agricultural commodities, against global equity and debt benchmarks, commodities, precious metals, and bitcoin. DBA is up over 20% year to date -- more than twice the appreciation of the closest asset class, long-dated US Treasury bonds, which are up 9.3%.
Personally I'm not buying, though I think agriculture will continue to outperform. Food shortages may be a structural, long-term challenge, in the views of some.
