*美元指数在接近两周低点后上涨0.1%
*白银的技术面仍较为脆弱
*投资者等待周五的美国非农就业报告
金价在周一稍早触及近四周高位后下滑，因美元从低点回升，且投资者们在本周稍晚公布关键美国非农就业报告之前持谨慎态度。
美国东部时间下午1点33分，现货黄金下跌0.4%，至1,808.67美元/盎司，此前曾触及8月4日以来的最高水平。美国黄金期货下跌0.4%，至1,812.2美元。
美联储主席杰罗姆·鲍威尔周五在杰克逊霍尔年会上发表讲话后，金价周一开盘上涨。
鲍威尔表示，美联储可能会在今年缩减购债计划，但对美联储开始缩减资产购买计划的确切时间没有任何指示，这推高金价。
然而，随后金价下跌，因为美元指数试图反弹，美元指数在鲍威尔发表讲话后曾跌至近两周低点。
金属聚焦南亚高级研究顾问Harshal Barot称：“总体而言，货币政策背景仍将保持宽松，存在着围绕新冠病毒德尔塔变种、中国经济放缓的担忧、地缘政治紧张局势的不确定性。”
他表示，所有这些因素都为金价提供了看涨背景。
Barot补充称：“鲍威尔明确区分了缩减购债规模和加息。尽管缩减购债规模可能在今年开始，但是距离加息还很遥远。”
Kitco Metals高级分析师Jim Wyckoff表示：“市场开始感觉到，今年将出现一定程度的缩减购债规模，但力度可能不会吓到市场。”
然而，Wyckoff表示，在美国非农就业报告于周五公布之前的谨慎可能在本周打压金价，强劲的非农就业报告可能令美联储鹰派官员在主张退出超宽松货币政策时拥有更多筹码。
较高的利率增加了持有无息黄金的机会成本。
宝盛下一代研究主管Carsten Menke表示，杰克逊霍尔会议上的言论应该不会对金银产生“根本性”影响。
“我们仍然非常相信经济将持续复苏，通胀飙升是暂时的，这将导致黄金和白银价格略微走低。”Menke称，并指出，通胀和经济复苏是市场的主要推动力。
投资者的焦点现在转向将在周五公布的美国8月非农就业数据，该数据可能进一步揭示就业市场的复苏，并影响美联储的缩债策略。
Kinesis市场分析师Carlo Alberto De Casa称：“从技术角度看，黄金仍处于有利环境。”
“我们也看到白银出现反弹，但技术面仍更为脆弱，因白银的表现仍不如黄金。”
银价下跌0.3%，至23.93美元/盎司；铂价下跌0.3%，至1004.48美元；钯价上涨2.5%，至2479.50美元。
PRECIOUS Gold pulls back as dollar strengthens, caution sets in
Dollar index up 0.1% after hitting near two-week low
Investors await U.S. payrolls report on Friday
Aug 30 (Reuters) - Gold prices slipped, after touching a near a four-week high earlier on Monday, as the dollar ticked up from its lows and investors showed caution in the run-up to the release of a key U.S. jobs report later in the week.
Spot gold fell 0.4% to $1,808.67 per ounce by 1:33 p.m. EDT (1733 GMT) after touching its highest level since Aug. 4. U.S. gold futures settled down 0.4% at $1,812.2.
Gold initially rose on Monday in the wake of U.S. Federal Reserve Chair Jerome Powell's speech to the annual Jackson Hole economic conference on Friday.
Powell said tapering of the U.S. central bank's bond-buying program could happen this year but gave no indication as to the exact timeline for the Fed to start cutting its asset purchases, sending gold higher.?read more <https://www.reuters.com/business/feds-powell-weighs-delta-risk-gives-no-signal-start-bond-buying-taper-2021-08-27/>
However, gold then fell as the dollar index, which had slipped to nearly a two-week low in the wake of Powell's speech, attempted a rebound.
"The marketplace is starting to get a sense that there will be some tapering this year but maybe not with the aggressiveness that would spook the marketplace," said Jim Wyckoff, senior analyst at Kitco Metals.
Wyckoff, however, said that caution ahead of the scheduled release on Friday of the U.S. nonfarm payrolls report could weigh on gold this week, with a strong number potentially giving hawkish Fed officials more leverage in arguing for a move away from ultra-easy monetary policy.
Higher interest rates increase the opportunity cost of holding non-yielding bullion.
Carsten Menke, head of next generation research at Julius Baer, said comments made at the Jackson Hole conference should have no "fundamental" impact on gold and silver.
"We remain very much convinced about a continued economic recovery and a temporary inflation spike, leading gold and silver prices somewhat lower," Menke said, noting that inflation and the economic recovery were key drivers for the market.
Silver fell 0.3% to $23.93 per ounce, platinum dropped 0.3% to $1,004.48 and palladium rose 2.5% to $2,479.50.
