There's a story out to the effect that the Federal Reserve may follow the Bank of Canada's lead and announce that it will not increase interest rates for several months or so (subject to some escape hatch if inflation starts to be a problem):
US fed may speak with Canadian accent: While policy makers have signaled they accept an increase in longer-term Treasury yields as the economy improves, some are concerned at any premature anticipation of rate rises. Fed staff have examined the Bank of Canada's public intention of foregoing an increase until 2010, according to a person familiar with the matter, without concluding the statement has proven effective.
This may be a good idea, but it would seem from the changing shape of the yield curve that those expectations are already in place:
From this graph, you'd be hard-pressed to tell which country had recently committed itself to low interest rates over the next year, and which had not.
