Sector Commentary

Currencies:  Prices across the global currencies markets were stable throughout the month and the U.S. dollar remained strong.  The British pound, euro, and Australian dollar finished the month essentially unchanged.  The Japanese yen was more volatile, as its value decreased in anticipation of quantitative easing, only to reverse direction after the Bank of Japan unexpectedly declined to announce any additional actions. 

Energy:  Crude oil prices continued to fall during the month due to overproduction and abundant supplies and finished the month 14% lower, posting the largest one-month decline in the past year. 

Equities:  Equities sectors rebounded from post-Brexit declines during the beginning of July.  The markets moved lower and traded within a narrow range during the middle of the month and then rallied to end the month higher due to corporate earnings reports in the U.S. which generally contained smaller-than-expected declines in quarterly earnings.

Fixed Income:  Fixed income markets also traded in narrow ranges during July as global investors assessed whether the Federal Reserve would raise interest rates in September, the Bank of Japan would expand its accommodative monetary policy, and the Bank of England and the ECB would intervene in the aftermath of the Brexit referendum. 

Grains/Foods:  Prices for corn, soybeans, wheat and cocoa fell slightly during July in the absence of any significant information or adverse weather conditions that would significantly impact the supplies of the commodities.

Metals:  Gold, silver and platinum prices moved higher during the month as political unrest in Turkey and the Eurozone sparked a flight to safety.  Uncertainty about the need for and timing of additional quantitative easing initiatives added to demand for precious metals.
