HKEx has so far not looked to merge but now faces more competition from other trading pools
The Hong Kong stock exchange has said it is open to international alliances, suggesting there is likely to be more consolidation among exchanges.On Wednesday, the London Stock Exchange confirmed a tie-up with TMX of Canada, while Deutsche Boerse and NYSE Euronext said they were in advanced talks.
News of the talks boosted shares in the exchanges in early Thursday trade.
Deutsche Boerse jumped 6% on Thursday, while NYSE Euronext's Paris-listed shares rose 8%.
However, shares in Hong Kong Exchanges and Clearing (HKEx) dropped 4.9% - its biggest fall since May 2009 - on fears the mergers elsewhere would increase competition.
"Due to changes in the financial market landscape, HKEx will consider international opportunities for alliances, partnerships and other relationships that present strategically compelling benefits consistent with its focus on markets in China," the exchange said in a statement.
