Futures brokers in US rules hike

US regulators are planning to boost capital requirements for futures brokers by at least 25 per cent, sparking concerns many of the brokers could be forced out of business.<br /><br />The Commodity Futures Trading Commission (CFTC) is thought to be keen to push through the plans, which come as part of President Obama&rsquo;s bid to boost the amount of capital financial services firms have to hold, to prevent a repeat of the credit crunch.<br /><br />The CFTC is insisting that firms submit their comments on the plans by today.
