U.S. derivatives regulators are expected to file “more than 10” fraud and market-manipulation cases in the next weeks as the Commodity Futures Trading Commission chairman implements his back-to-basics approach, the Wall Street Journal reported. The stepped-up enforcement comes after the CFTC recorded a big drop in fines and enforcement actions during the fiscal year that spanned the transition from the Obama administration to the Trump administration. Enforcement has picked up since then. The agency has already filed 11 manipulation-related cases in the current fiscal year, which ends in September, just one shy of its annual record.
