The Bank of England added "only" GBP 25 billion to the QE measure. Just for perspective, relative to the size of the economy, this would be like the Fed announcing an extra USD 200 billion in QE. We're not talking about "chump change" here. The next important data release from the BoE is next Wednesday's Quarterly Inflation Report. The BoE's statement noted that inflation is likely to increase from here (this is partially a result of the year-on-year comparisons becoming more reasonable as the commodity bubble popped last summer). There will be plenty of volatility on that release, depending on how the bank projects the threat of inflation.
