GBP/USD: asymmetrical response by sterling - BBH

Analysts at Brown Brothers Harriman explained that there seems to be an asymmetrical response by sterling.  

Key Quotes:

"The market seems more eager to sell sterling on disappointing news than to buy it on favorable news.  

There was much trepidation, for example, over the third leg of this week's bond buys, and it was for the longest duration.  

It went off without a hitch, but sterling slipped back down to finish just above $1.30.  Sterling has not closed below $1.30 since July 8.  Intraday resistance is seen in around $1.3025."
