New Delhi, Feb 22 (TIWN) Oil prices are climbing on fears that the Ukraine-Russia crisis will disrupt supply chains across the world, BBC reported.

The UK and several western allies have threatened sanctions on the country. Russia is the second largest exporter of crude oil after Saudi Arabia. It is also the world's top producer of natural gas. The border tensions may have "substantial implications", Sue Trinh of Manulife Investment Management said. Sanctions forcing Russia to supply less crude or natural gas would have "important impact on the global economy," she added, the report said.
