From the Senators press release:
The residual interest rule from the CFTC will eventually require futures customers to fully cover the margin of their futures contracts by the morning of the day following a trade. In order to comply with the new rule, brokers would be more likely to demand drastically increased initial payments from farmers, hurting the availability of funds that support the agriculture industry. The end result may drive some farmers out of futures markets due to increased costs or restrict capital that could otherwise be used to hire, make capital improvements, and make other critical investments.The Senators’ bill, S. 2601, the Risk Hedging Protection Act would provide futures customers with an additional day to get their needed payments to brokers to meet the margin call, while still protecting customers and the financial markets. The bill mirrors legislation, H.R. 4413, already approved by the House Agriculture Committee and the full House of Representatives.
Read the bill.
