Sector Commentary

Currencies: The U.S. dollar strengthened on hopes for progress in trade talks between the U.S. and China. The Australian and New Zealand dollars weakened after Australia’s central bank considered a possible rate cut as it acknowledged growing economic risks. The Japanese yen fell following data of weakening economic performance. The British pound strengthened after Prime Minister Theresa May said Parliament will be allowed to vote on a “no-deal” Brexit or delay.

Energy: Crude oil prices rose due to new U.S. imposed sanctions on Venezuela, reduced output by OPEC and a continued slowdown in U.S. drilling activity. Heating oil prices moved higher on lower inventories.

Equities: Global equity markets rose on reports of progress in trade talks between the U.S. and China and a boost in energy stocks amid rising oil prices.

Fixed Income: Global fixed income markets declined slightly on optimism for a U.S.-China trade deal and easing Brexit fears.

Grains/Foods: Wheat and corn markets fell on muted demand and abundant supplies. Coffee prices declined over 10% due to excess supplies and a weaker Brazilian real. Cocoa markets moved higher as demand increased and concerns arose about poor weather conditions in the Ivory Coast. Cotton markets moved higher on optimism about a possible trade deal between the U.S. and China.

Metals: Gold and silver markets moved lower as a stronger dollar reduced demand for the safe-haven assets. Copper and other base metal prices rose on firming demand and hopes of a U.S.-China trade deal.
