In October 2010, the recently appointed CEO of the Singapore Exchange (SGX) wanted the SGX to grow faster than organic growth alone would allow. The most logical acquisition target was the Australian Securities Exchange (ASX). Executives from the SGX and the ASX announced an agreement to merge. The two exchanges would remain separate legal entities for regulatory purposes but both would be owned by ASX?SGX Limited, a new holding company that the deal would establish. But why did the merger fail? This left executives at the SGX and other foreign securities exchanges pondering whether the conditions the Australian Treasurer specified for a merger could ever be met and, if so, would a foreign securities exchange really be allowed to acquire the ASX?
