Growth is slow in the U.S. and there's no expectations at all that the Fed will cut rates at this week's meeting. Growth is even a bit slower in Europe and isn't expected to get much immediate lift from the ECB's latest expansion of its quantitative easing program. And news will be especially heavy from Japan where a run of key data will be posted this week along with the Bank of Japan's latest decision which, despite the major earthquake, may or may not see a deepening in negative policy rates.
