Which central bank will shock markets next?

Central banks around the world surprised markets with a string of unexpected moves in recent weeks.

It started with the Swiss National Bank's (SNB) decision to unpeg its currency from the euro earlier this month, followed by a larger-than-expected bond-buying program from the European Central Bank (ECB) on January 22. Last week, the Danish central bank cut interest rates to a record low for the third time in 10 days, while Russian policymakers reduced the central bank's main interest rate amid mounting recession fears.

In Asia, the Reserve Bank of India (RBI) cut its key repo rate by 25 basis points to 7.75 percent on January 15, more than two weeks before its scheduled meeting, catching markets by surprise. The Monetary Authority of Singapore (MAS) followed the RBI's footsteps with an inter-meeting easing move last Wednesday.

In light of this, which central bank do you think will pull the next surprise policy move?
