It has signed panamax charters with Cargill International and Norden worth a collective $4.35m, a statement said.
Cargill has hired the 73,500-dwt Naias (built 2006) on a 10 to 13 month contract.
A rate of $6,800 daily has been agreed, against a spot market of $8,656 per day on Monday.
Norden has paid $7,000 daily for the 73,600-dwt Thetis (built 2004) over an 11 to 14 month period, Diana said.
The deals mean Diana is in for slightly reduced income from both of the vessels.
Naias was previously fixed to Bunge at $8,500 daily and the Thetis to EDF at $8,300 per day.
Dry Cargo rates have been improving over the past few sessions with the BDI hitting 900 points for the first time this year.
Ben Nolan of Stifel says panamaxes improved by over 16% last week.
"Overall rates are low, but they are at least trending away from vessel opex and providing some much-needed breathing room," said Omar Nokta of Clarksons Platou Securities.
