Under the influence of the increase in U.S. employment in April and the news that Greece may exit the euro zone, the rise in the U.S. dollar has put heavy pressure on oil prices. The "cliff-like" decline in commodities continues. In the past two days, crude oil has taken over the baton from silver and become the new main force leading the decline in commodities. So far this week, commodities may have suffered their biggest decline in two years. Dragged down by the general decline in prices of energy, metals and other commodities, most Asia-Pacific stock markets closed lower on Friday, extending the decline of U.S. stocks overnight. As of Friday's close, the price of light crude oil futures for June delivery on the New York Mercantile Exchange fell by $2.62 to close at $97.18 per barrel, a decrease of 2.63%, and a weekly decline of 14.7%. The price of North Sea Brent crude oil futures for June delivery in the London market fell by US$1.67 to close at US$109.13 per barrel, a decrease of 1.51%, and a decline of 13.31% for the whole week. The price of light crude oil futures for June delivery in the New York market closed at US$97.18 per barrel, a decline of 14.7% for the whole week. The price of North Sea Brent crude oil futures for June delivery in the London market closed at US$109.13 per barrel, a decline of 13.31% for the whole week. Although oil prices have experienced a sharp correction recently and may continue to fall in the short term, in the medium to long term, global crude oil supply and demand are tightening, and oil prices are expected to return to or even exceed the recent high of nearly $115 per barrel before 2012. But Goldman Sachs' bullish comments didn't stop oil prices from falling. Let me add: New York oil prices are inevitably unaffected by the rise and fall of international oil prices.
