The Monetary Authority of Singapore is working with private industry to bypass routing trades via Tokyo or London.

  • Building trading engines in Singapore itself, which will speed trades; UBS and Citi have already done so.
  • Further, the government is offering tax incentives to enhance Singapore's appeal as a hub to trade

Adds Bloomberg:

  • The heart of the challenge for Singapore is latency -- the 10th of a second extra it takes to route a trading order through servers in Tokyo or London or New York, where most major banks have traditionally sited their trading engines. To capture big-volume players like hedge funds and high-frequency traders, the government needs to persuade companies to build those expensive systems and data centers in Singapore.

You can get an inkling of the impact on FX liquidity in the Asian timezone with a glance at a graphic in that Bloomberg story linked above:
