May 21 2015: The GBP is strongest. The CAD is the weakest

As North American traders enter for the trading day, the GBP is strongest currency, while the CAD is a weakest.

The GBP benefited from better-than-expected retail sales for the month of April. The headline number increased by 1.2% vs. March. This was higher than the 0.4% expected. Taking out fuel, the rise of 1.2% was also much better than the expected 0.2% gain.

The CAD is the weakest currency today. In general the commodity currencies are lower in trading today. Typically, it might take a decline in oil to get the CAD moving lower. Not today. Crude and Brent oil are each up about 1%. Technically, the price of the USDCAD tested a support/old resistance level ( see hourly chart below) and could not extend below. The last few hours have seen a sharp rebound. Sometimes it might be the chart that is the main catalyst ; ) (PS most of the decline in the CAD was from the benefit of the stronger GBP too as GBPCAD is up 1.03% on the day).
