伦敦10月27日电：周二，美元兑欧元、日元和英镑小幅走高，交易员们正严阵以待一系列将塑造利率前景的重要央行会议，以及可能波及所有资产类别的重要企业财报。
LONDON Oct 27 : The dollar nudged higher on the euro, yen and pound on Tuesday, as traders braced for a barrage of major central bank meetings that will shape the interest rate outlook, as well as key corporate earnings that could ripple through all asset classes.
美联储将于周三宣布最新的政策决定，欧洲央行紧随其后于周四登场，日本央行则在周五为本周画上句号。
The Federal Reserve is set to announce its latest policy decision on Wednesday, the European Central Bank is up on Thursday, and the Bank of Japan rounds out the week on Friday.
预计这三家央行都将维持利率不变，因此市场的焦点将放在决策者对其前景释放的任何暗示上。
All three are expected to keep rates on hold, so the focus will be on any hints policymakers give on their outlook.
同样对美元有利的——尤其是对日元和瑞士法郎等避险货币而言——是股市的平静度有所增加。上周，股市曾因对高飞的人工智能股票的担忧重燃而剧烈动荡。
Also helping the dollar, especially on safe havens like the yen and Swiss franc, was greater calm in the equity market which was roiled last week by renewed worries about high-flying AI stocks.
荷兰国际集团外汇分析师弗朗切斯科·佩索莱表示：“本周初美元找到了强劲支撑，因为人工智能相关情绪的趋稳，使市场能够重新回归美联储偏鹰派立场和高能源价格这一更广泛的支撑背景。”
"The dollar has found good support early this week, as stabilising AI-related sentiment has allowed markets to reconnect with the broader supportive backdrop of a hawkish Federal Reserve and high energy prices," said Francesco Pesole, currency analyst at ING.
美国货币兑日元上涨0.16%至157.73，而欧元下跌0.17%至1.1154美元，英镑下跌0.14%至1.3324美元。
The US currency was up 0.16 per cent on the yen at 157.73, while the euro slid 0.17 per cent to $1.1154 and the pound dipped 0.14 per cent to $1.3324.
佩索莱还表示，他认为市场正处于美联储会议前的仓位调整期，预计主席凯文·沃什将重申其对抗通胀的承诺，这将巩固美元的底部支撑。
Pesole also said he thought markets were positioning ahead of the Fed meeting, anticipating Chair Kevin Warsh will reiterate his commitment to fighting inflation, something that will reinforce the floor under the dollar.
此外还有其他几个因素交织在一起。周二公布的数据显示，日本9月份衡量服务业通胀的一个关键指标较上年同期上涨3.7%，这表明价格压力不断加大，很可能让日本央行继续走在进一步加息的轨道上。
Several other factors are in the mix as well and a key gauge of Japan's service-sector inflation rose 3.7 per cent in September from a year earlier, data showed on Tuesday, a sign of increasing price pressures that will likely keep the central bank on track for further interest rate hikes.
同样在日本，财务大臣片山皋月周二表示，政府已准备好在外汇市场采取果断行动，这提醒市场东京方面愿意干预以支撑本国货币。
Also in Japan, Finance Minister Satsuki Katayama said on Tuesday the government stood ready to take decisive action in the currency market, reminding markets of Tokyo's willingness to intervene to prop up its currency.
科技财报的影响：更广泛的市场叙事也将受到本周多家企业财报的检验，其中包括人工智能超大规模企业Alphabet、微软和亚马逊。
TECH EARNINGS IMPACT The broader market story will also be tested by a number of corporate earnings this week including from AI hyperscalers Alphabet, Microsoft and Amazon.com.
日元是上周表现最好的主要货币之一，兑美元走强约0.75%，创下9月初以来的最大涨幅，原因是股市对人工智能的担忧引发了对日元的抢购。
The yen was among the best-performing major currencies last week, strengthening around 0.75 per cent on the dollar, its most since early September, as AI jitters in the equity market spurred a rush into the currency.
与此同时，欧元有望成为10月份表现最差的发达市场货币，兑美元下跌1.5%，受到高昂能源成本、法国国债波动以及对法国财政状况担忧的打击。
Meanwhile, the euro was on track to be the worst-performing developed market currency in October, down 1.5 per cent on the dollar, bruised by high energy costs, and the volatility in French government bonds and worries about France's fiscal position.
新西兰储备银行和加拿大银行也将于周三宣布各自的政策决定，预计这两家央行都将加息。
The Reserve Bank of New Zealand and the Bank of Canada also announce their policy decisions on Wednesday, with both expected to raise interest rates.
新西兰储备银行将于周三开会，在此之前新西兰元表现优于大盘，周二兑美元上涨0.1%至0.5687美元。加拿大元兑美元汇率保持稳定，报1.4021加元兑1美元。
The RBNZ meets on Wednesday, and the New Zealand dollar was outperforming ahead of that, up 0.1 per cent on the dollar on Tuesday at $0.5687. The Canadian dollar was steady at $1.4021 to its US counterpart.
