Sector Commentary
Grains/Foods: Corn prices rose nearly 9% due to two factors: poor weather forecasts in major U.S. and European farming regions and increased corn demand from ethanol producers. Sugar prices fell sharply based on strong production forecasts from Thailand, the world second-largest exporter.
Metals: Precious metals markets moved steadily higher on increased buying by investors seeking to hedge against U.S. dollar weakness. Safe-haven buying caused by the economic situation in Japan and political unrest in the Middle East and Africa also played a role in driving precious metals markets higher. Copper prices declined due to forecasts for weaker industrial demand caused by the recent Japanese earthquake and potential interest rate hikes in China.
Currencies: The U.S. dollar weakened against global counterparts on concerns about economic growth in the U.S. Weak employment data and reports from Standard & Poor’s called for a prolonged U.S. economic recovery and put further pressure on the dollar. The euro and Swiss franc strengthened against the dollar as speculators believed that monetary policy shifts in the U.S. would lag those of its European counterparts.
Equities: North American and European equity markets moved predominantly higher, fueled by strong corporate earnings reports for the first quarter. Japanese equity markets finished the month slightly higher due to heavy buying by investors looking to take advantage of low share prices caused by recent downtrends. The Hong Kong Hang Seng index fell due to concerns over potential Chinese interest rate hikes which could hinder the nation’s economic growth.
Fixed Income: U.S. Treasury markets posted monthly gains as an unexpected rise in jobless claims put pressure on investor risk appetite. The current crisis events in Japan and turmoil in the Middle East and Africa combined to support increased demand in this sector.
Sincerely,
