By Candice Zachariahs Nov. 4 (Bloomberg) -- The Australian dollar extended declines after the Reserve Bank of Australia cut interest rates by more than economists estimated, reducing investor appetite for higher-yielding assets. New Zealand's currency also fell. Australia's dollar slid to 66.69 U.S. cents as of 2:45 p.m., after trading at 67.17 cents just before the RBA announced the 0.75 percentage point cut to 5.25 percent at 2:30 p.m. It traded at 65.93 yen from 66.34 before the decision. ``The Aussie might come under downside pressure from the bigger rate cut,'' said Besa Deda, acting chief economist and strategist at St. George Bank Ltd. in Sydney, referring to the currency by its nickname. ``Clearly, international conditions, with further signs that China is slowing, are one of the key factors for the RBA to cut rates.'' Fifteen of 16 economists surveyed by Bloomberg News forecast a 50 basis-point cut, with one predicting 25 basis points. Today's decision follows a 1 percentage point reduction last month, the bank's biggest cut since May 1992 as the economy was emerging from a recession. New Zealand's dollar declined 0.6 percent to 58.85 U.S. cents from 59.23 cents in Asia yesterday. It bought 58.20 yen from 58.81. Australia's currency has plunged 28 percent against the dollar over the past three months and 36 percent versus the yen after the collapse of Lehman Brothers Holdings Inc. froze credit markets and prompted investors to dump higher-yielding assets on concern over a global recession. New Zealand's dollar is 19 percent and 27 percent lower versus the greenback and the yen, respectively. U.S. Stocks The currencies also declined after stocks in the U.S. fell on the worst contraction in manufacturing since 1982 and forecasts that the sagging economy will reduce profits. About 1 billion shares changed hands on the floor of the New York Stock Exchange, the slowest trading day since August. The S&P 500 lost 2.45 points, or 0.3 percent, to 966.3. ``For the Aussie to continue to recover the ground that was lost, particularly in the last couple of weeks, we would need to see stocks trading higher,'' said Robert Rennie, chief currency strategist in Sydney at Westpac Banking Corp. Australian government bonds advanced. The yield on the benchmark 1-year note dropped 16 basis points to 4.015 percent, according to data compiled by Bloomberg. The yield on 90-day bank bill futures fell to 4.47 percent from 4.95 yesterday. New Zealand's two-year swap rate, a fixed payment made to receive floating rates, declined to 6.31 percent today from 6.34 yesterday.
