2009 saw the regulators on both sides of the Atlantic continuing to push the boundaries of enforcement activity, with insider trading cases succeeding in relation to bonds and credit default swaps. This push can be expected to continue in 2010. The UK Financial Services Authority ("FSA") has issued sanctions even in face of clear evidence that the behaviour complained about was widely considered to be acceptable practice. This stance creates great uncertainty for those trading outside the equity markets, where regulatory guidance and precedent is less well developed. Significant questions have been raised about the extent to which credit default swaps are within the scope of the insider trading restrictions in the US and the UK.

In the equity markets, the Galleon hedge fund investigation in the US and recent FSA "clarification" about treatment of market rumour have reinvigorated the debate about the status of market "colour" and market "rumour" and when they can result in a restriction on trading. A resurgence of shareholder activism is also throwing up new questions about acceptable dialogue between shareholders seeking to promote good corporate governance.
