CBOT corn falls on strong dollar, economic uncertainty

March 21 (Reuters) - Chicago Board of Trade corn futures fell on a strong dollar and pre-weekend positioning against a backdrop of economic uncertainty, analysts said.

• CBOT May corn CK25 settled down 4-3/4 cents to $4.64-1/4 per bushel.

• For the week, most active corn Cv1 rose by 1.25%.

• The dollar climbed against the euro on Friday, on pace for its first weekly gain this month, as investors booked profits from the common currency's recent advance, and as the approaching April 2 deadline for reciprocal U.S. tariffs prompted caution.

• A stronger dollar tends to make U.S. exports more expensive and therefore less competitive on the global market.

• Analysts said traders are exiting positions prior to the weekend because of anxiety over any news that could break and contribute to greater economic uncertainty.

• Traders are also positioning ahead of the USDA's grain stocks and prospective planting reports, according to analysts. Due on March 31, the reports will show estimates for farmers' planting intentions in 2025. Farmers are expected to plant more corn this year.
