hourly chart of the GBP/USD pair:

The sterling is eyeing the 1.6 support mark as RSI on a 4 hour chart shows the pair in oversold zone. Further downside is expected as recovery in the UK is expected to be slow but a near-term slide will ride on dollar strength. Mid-week reports from the BoE warns of a slow recovery but analysts see an open window for the BoE to expand its asset repurchase programme to further support the recovery process.
In the near-term, the Euro appears to have lost its upside steam. Breaking through the bullish trend line on a thirty minutes chart during New York trading hours point to a possible reversal. The dollar gained against the loonie as investors dumped equities in apparent loss of risk appetite ahead of G20 summit.
