July 23 (Reuters) -Spot basis bids for soybeans shipped by barge to U.S. Gulf Coast terminals eased on Tuesday as farmers increased crop sales due to rising prices, traders said.

* Farmers sold soybeans, boosting available supplies, as futures prices Sv1 reached a two-week high after slumping to a 2020 low last week.

* CIF soybean barges loaded in July were bid at 78 cents a bushel over Chicago Board of Trade August futures SQ24, down 1 cent from Monday. Bids for August barge loadings were 62 cents over futures, down six cents.

* FOB export premiums for soybean shipments loaded from the Gulf in August were down six cents at around 87 cents over CBOT August futures. Premiums for deferred months strengthened, though, as prices in top-exporter Brazil looked less competitive, a trader said.

* Brazil's soybean exports are expected to reach 10.43 million tons in July, slightly below the 10.71 million forecast last week, Brazilian grains exporter association Anec said.

* For corn, CIF barges loaded in July were bid around 66 cents over CBOT September futures CU24, which was stable. Barges loaded in August were bid about 68 cents over futures, which was also flat.

* FOB offers for corn shipments loaded from the Gulf in August were steady at around 78 cents over September futures. Premiums for deferred months also remained steady, though a trader said the market is volatile as importers need supplies.

* Exporters struck deals to sell 200,000 metric tons of U.S. corn to unknown destinations for 2024/25 delivery, the U.S. Department of Agriculture said. A day earlier, USDA reported sales of 133,000 metric tons of U.S. corn to Mexico for 2024/25 delivery.
