Soybean futures have seen an increase due to a rise in domestic crush to 191 million bushels in January, a slight decrease from the same period last year. Iowa and Illinois were the top soybean crushing states. The decline in the US dollar in overnight trading has also made US supplies more appealing to international buyers. There is also market activity due to concerns over the future of the Black Sea Grain Initiative, which is crucial for the export of agricultural products from Ukraine.
