Oil prices increased on April 20, swamped by fears about tightening supply as the European Union (EU) considers a possible ban on Russian oil imports, which would further impede global oil commerce.

After reaching a high of $109.80, Brent oil futures finished up $1.53 to close at $108.33 a barrel. After earlier reaching a high of $105.42, U.S. West Texas Intermediate (WTI) crude futures ended up $1.60, or 1.6 per cent, at $103.79.

Consumers also reacted to continued disruptions in Libya, where blockades at major fields and export terminals have resulted in a loss of about 550,000 barrels per day of oil supply.
