Norges Bank will Twitter its interest rate decision on Wednesday, breaking ground for central banks using social networks to spread the word on monetary policy.

We believe we are the first in the world to use Twitter this way, Norges Bank spokeswoman Siv Meisingseth told Reuters.

She said Norges Bank was giving priority to its regular Internet announcements but would seek to Twitter the rate news at about the same time.
