亚洲交易时间星期四，美元兑日元在区间内震荡走高，缺乏交易诱因，投资者按兵不动。
美元兑日元的成交价为108.93日元，较周三的108.40日元略有上涨。
美元兑日元在5月3日跌至105.55美元，创下18个月以来的最低记录，随后开始反弹，在周三冲破109.93日元，因为东京当局不断向投资者强调日元仍保持强势。但美元很难继续走高，这无法证明情况正在好转。
东京三菱日联银行的全球市场调查部主管Minori Uchida说道：“美元兑日元从109日元跌至105日元，但是正逐渐恢复到三周前的水平，那时日本央行尚未计划采取额外的刺激措施。现在没有新的交易诱因能够把美元推上110日元。”
Uchida认为日元正在承受着上行压力，因为市场参与者对日本央行的货币政策缺乏信心，而且当前日本账户的盈余仍在增加。
再来看美元，美联储在今年内很可能继续放慢加息的步伐，削弱美元的上升势头。今年第一季度的消费者数据仍然缺少活力。虽然明天的消费者数据预期良好，但在短期内很难对美国经济强度和利率增长产生影响。
日本央行行长黑田东彦在周四发布了讲话，但投资者对其应甚微。
黑天表示，日本央行当前的货币政策是保持负利率并扩大基础货币规模，虽然没有实现通胀目标，但仍是当前“最适合”的货币政策。
他重申，若有证据证明需要进一步刺激以达到通货膨胀目标，日央行将会在数量，质量以及利率三个方面增大宽松的力度。
再来看其他货币对，欧元/美元的成交价由1.1426美元涨至1.1422美元。欧元/日元的成交价由123.92日元涨至124.23日元。
华尔街美元指数上涨了0.11%，涨至86.33。
Dollar moves higher against yen, but keeps running into resistance
The dollar was moderately higher against the yen in rangebound Asian trade on Thursday, with investors sitting on the sidelines amid a lack of fresh trading cues.
The U.S. currency USDJPY, +0.37% was changing hands at ¥108.93, compared with ¥108.40 late Wednesday in New York.
After falling to its fresh 18-month low of ¥105.55 set on May 3, the dollar gained traction against the yen in recent trade, hitting as high as ¥109.38 Wednesday, on Tokyo’s repeated verbal warnings against the Japanese currency’s strength. But the greenback is struggling to go further upside as it is weighed down by selling on recovery.
“The dollar has come back to ¥109 from ¥105. But it’s just back to where it was three weeks ago before expectations for the Bank of Japan’s extra stimulus mounted,” said Minori Uchida, head of Tokyo global markets research at Bank of Tokyo-Mitsubishi UFJ. “There is no fresh trading cues to bring the dollar higher toward ¥110.”
Uchida said the yen is under upward pressure amid the market participants’ lack of faith in the BOJ’s monetary policy and given Japan’s increasing current account surplus.
With regard to the dollar, the Federal Reserve will likely remain slow to raise rates this year, weakening upside momentum of the dollar. Amid consumer data still lacking vigor in the first quarter of this year, “even assuming strong consumption figures tomorrow, that may not immediately signal the U.S. economic strength and rate increase,” said Uchida, in reference to the U.S. April retail sales scheduled to come out Friday.
Investors showed muted reaction to BOJ Gov. Haruhiko Kuroda’s remarks in parliament on Thursday.
Kuroda said the central bank’s current monetary policy, consisting of negative interest rates and asset purchases, is “appropriate” even though it has been unable to achieve its inflation target.
He also reiterated that the central bank will choose from options in its arsenal that include quantitative and qualitative measures, and interest rates if the need for additional easing arises.
In other currency-pair trading, the euro EURUSD, -0.1663% was at $1.1422, compared with $1.1426. The common currency EURJPY, +0.20% was at ¥124.23 from ¥123.92.
The WSJ Dollar Index BUXX, +0.28% a measure of the dollar against a basket of major currencies, was up 0.11% at 86.33.
