Crude oil prices slumped on Monday on profit-taking. The surprising decline of almost US$5 in just a few minutes on very high volume triggered the CFTC to investigate the case with the CME. The front-month contract for WTI crude oil slipped to as low as 94.65 before ending the day at 96.62, down -2.40%, while the equivalent Brent crude contract plunged to a 6-week low of 111.5 before settling at 113.79, down -2.66%. Gold also faced profit-taking and USD's recovery, sending the Comex benchmark contract -0.12% lower. Market sentiment turned cautious, following the excitement last week due to QE3, as the New York Fed manufacturing index fell to the lowest level in more than 3 years. Territorial disputes between China and Japan over Diaoyu islands and the resulting anti-Japanese protests have caused a number of Japanese firms to temporarily shut their Chinese operations. Asian shares declined due to rising geopolitical tensions in the region.
