Sector Commentary

Currencies: The U.S. dollar strengthened as the growth of the U.S. economy slowed less than expected and as volatility in the equity markets increased demand for safe-haven assets. The Canadian dollar weakened when the central bank raised interest rates and indicated additional hikes would be needed to control inflation. The euro weakened on disappointing economic reports in the Eurozone and over concerns about Italy’s debt crisis. The British pound weakened on concerns about whether or not a Brexit agreement can be reached.

Energy: Crude oil prices fell on rising inventories and on concerns a slowing global economy will reduce future demand. Natural gas prices rose as inventories remained significantly below their five-year average and weather forecasts predicted cooler weather.

Equities: Global equity markets were down due to the unresolved trade dispute between the U.S. and China, on rising interest rates and due to the Italian debt crisis.

Fixed Income: U.S. fixed income markets declined as the Federal Reserve continued to gradually raise interest rates. European fixed income markets moved higher on weaker-than-expected economic data and on concerns surrounding Brexit negotiations.

Grains/Foods: Corn markets rose after the USDA lowered its estimates for crop production. Wheat markets declined on expectations of increased global supplies. Sugar and coffee markets rose 26% and 10%, respectively, on a strong Brazilian real and on lower output. Cocoa markets rose on higher demand and on concerns weather in West Africa would lower production.

Metals: Gold prices rose as a decline in global stock markets increased demand for the safe-haven asset. Copper and base metals moved lower on muted demand and on renewed trade tensions between the U.S. and China.
