CORN RALLY: Corn prices hit the highest level in nearly three years Monday on expectations that supplies will remain tight even if a bountiful crop is produced this summer.
SILVER NOTE: Silver hit a 31-year high on stronger interest from investors and retailers. The price was a record in dollar terms but still well below its peak in 1980 after accounting for inflation.
DRIVING OIL: Unrest in the Middle East sent oil to a 30-month high above $108 per barrel. Traders are concerned the tensions may disrupt the flow of supplies.
