Oct 28 (Reuters) -Spot basis bids for soybeans shipped by barge to the U.S. Gulf Coast eased on Monday from two-year highs last week as freight rates slipped and as exporters had filled their most pressing immediate loading needs, traders said.

* Spot barge freight rates pulled back from harvest season highs on Monday, although shipping costs remained elevated due to strong near term demand for empty vessels and amid some shipping disruptions caused by low water on the Mississippi River. BG/US

* CIF October soybean barge bids fell to 130 cents over Chicago Board of Trade November SX24 futures, down 25 cents from Friday's peak.

* Barges loaded in the first half of November traded at 120 cents over futures while full-month November loadings traded at 110 cents over futures, both down slightly from bids late on Friday, traders said.

* Tight export loading capacity at Gulf Coast terminals supported spot FOB premiums.

* Soybean FOB offers dipped to 155 cents over futures for shipment in the first half of November and 150 cents over futures for last half shipment, each down 5 cents.

* CIF corn basis bids were flat to lower on Monday on easing freight costs. But values overall remain underpinned by strong export demand.

* The U.S. Department of Agriculture on Monday confirmed private sales of 124,000 metric tons of U.S. corn to Japan and 120,000 to undisclosed buyers. It was the ninth straight day with a daily corn sales announcement.

* CIF October corn barge bids fell 2 cents to 98 cents over CBOT December corn CZ24 futures.

* FOB Gulf offers for November corn shipments were held at 125 cents over futures.
