U.S. crude dazes after yesterday's tumble

Crude prices wavered on Friday ahead of the weekend after sliding yesterday due to instability in crude's performance as markets remain cautious following Britain's vote to exit the European Union. 

U.S. crude futures last traded at $48.35 a barrel, compared to the opening price of $48.38, with an intraday high at $48.75, and a low at $47.88. 

Crude's wavering comes after a battering yesterday, while the dollar returned lower today versus a basket of rivals, sending prices into sideways trading. 

Dollar lost ground against main currencies despite upbeat manufacturing data from the U.S., which would've normally buoyed crude prices, but instability forced it into dithering. 

The dollar index, measuring the greenback's performance against a basket of six major currencies, last traded at 95.66, compared to the opening of 95.88, with a session-low at 95.40, and a high at 96.08, after the index hit a three-month high this week at 96.70.
