Sector Commentary

Currencies:  The euro weakened after the European Central Bank suggested it would expand its monetary stimulus efforts.  The British pound strengthened amid better-than-expected industrial production in the U.K.   The U.S. dollar rallied after the Federal Reserve suggested a December 2015 interest rate hike remained possible. 

Energy:  Crude oil markets finished slightly higher after OPEC suggested it might reduce production and after data showed U.S. inventories had risen less than expected.  Natural gas and heating oil prices fell as moderate weather in the U.S. reduced demand and supplies rose.

Equities:  Global equity markets rallied on stronger-than-expected earnings from key U.S. firms.  The decision to cut interest rates by the People’s Bank of China supported investor optimism and furthered the rally in equities.

Fixed Income:  U.S. Treasuries declined because of strong upward moves in the equity markets and reduced demand for safe-haven assets.  German Bund markets rose due to increased buying following the European Central Bank’s comments about expanding economic stimulus in the Eurozone.  U.K. debt markets moved lower due to strength in the equity markets.

Grains/Foods:  Corn prices fell in anticipation of a near-record crop.  Wheat prices rose as adverse weather in major farming regions in the U.S. and abroad threatened future supplies.  Sugar markets rose almost 20% as rains in Brazil threatened to disrupt harvesting.  Cocoa prices rose as extended dry weather in Ghana, the world’s second largest producer, reduced estimates for this year's crop output.

Metals:  Precious metals markets moved higher on speculation weakening global economic growth will cause the U.S. Federal Reserve to further delay raising interest rates.  Precious metals markets also moved higher in reaction to a larger-than-expected increase in the U.S. trade deficit.  Base metals markets fell due to ongoing concerns regarding the outlook for industrial demand by China.
