The Bank of England has hinted that it could raise rates sooner than expected amid concerns that the market has been underestimating the odds that a Federal Reserve rate hike could come sooner than later.
"Investors are beginning to worry that it's a global shift and that rates, except for Europe as a whole, might be seeing the start of their long, slow uphill climb. That's like a dark cloud hanging over investors mindsets right," Stovall remarked.
