Oil prices climbed by $2 a barrel on Monday, with benchmark Brent hitting a one-month high and US crude topping $30 supported by optimism about the re-opening of economies and output cuts by major producers.
Brent crude was up $1.99, or 6.1%, at $34.49 a barrel by 1041 GMT, its highest level since mid-April.
US West Texas Intermediate (WTI) crude was up $2.46 or 8.4% at $31.89 per barrel, its highest since mid-March.
