By Carolina Pica Of DOW JONES NEWSWIRES SANTIAGO (Dow Jones) -- The Chilean peso ended at a six-week low closing against the dollar Tuesday, on China's slower growth outlook for 2012 and on the tumble copper prices took on international markets. The peso ended sharply weaker at CLP491.30 to the dollar versus Monday's close of CLP485.40. During the session, the peso traded in a broad range of CLP486.90 to CLP492.70. Chile produces a third of the world's copper and China is one of its biggest customers. With a lower growth target of 7.5% for the Chinese economy, traders see demand for the red metal easing. The London Metal Exchange's bellwether three-month copper contract fell to its lowest level in two weeks, sliding 3% on Monday's closing price to $8,250 a metric ton. Jitters regarding global growth--in light of the deceleration in China and data out of Europe showing a 0.3% economic contraction in the fourth quarter of last year--and a weaker euro contributed to the peso's slide. "The market was also concerned about the global growth outlook," said Francisca Roa, strategist at Netgociando. During the session, the peso tested a significant support level at around CLP492-CLP493 and will likely test it again during the remainder of the week if the international outlook worsens, another currency trader said. In the fixed-income market, yields on inflation-indexed Chilean central-bank bonds, or BCUs, ended lower tracking the tumbles in international markets on global growth concerns. The yield on five-year BCU bonds closed at 2.20%, from 2.26% on Monday, while the yield on 10-year BCUs closed at 2.38%, from 2.40% the previous session. Bond yields and prices move in opposite directions.
