Crude prices fell to a three-month low in a volatile week of trading, buffeted by traders increasingly worried about an economic downturn.
West Texas Intermediate fell three of five trading days on the New York Mercantile Exchange, led by a $8.25 plunge on Tuesday that sent prices below $100 a barrel for the first time since early April. Prices remained under $100 the rest of the week, managing to add $1.81 Friday to close at $97.59 per barrel. Prices were down 6.9 percent for the week, the second consecutive weekly loss. The posted price closed at $94.07, according to Plains All American.
