Commodity markets this week have taken fright at the turmoil in Bahrain, which has caused another spike in oil prices. The market had temporarily recovered following the past month's record-breaking levels per barrel due to the instability in the Middle East. With Libyan production already near zero, markets reacted badly to new demonstrations in Bahrain and the risk it may spread to neighbouring Saudi Arabia. Brent crude futures broke back above $113 a barrel.
