TOKYO, Sept 26 (Reuters) - The dollar kept to tight ranges on Wednesday as investors focused their attention on the Federal Reserve's policy review later in the day as global markets fret over an escalating trade row between the United States and China.
The U.S. currency slipped against the Australian and New Zealand dollars, which were partially underpinned by a survey showing a bounce in New Zealand business sentiment.
Global markets have been on edge in the past few months as the heated Sino-U.S. trade dispute stoked uncertainty about the outlook for global growth and broader monetary policy for some developed and emerging market economies.
The Fed will end its two-day policy meeting later on Wednesday at which it is expected to raise interest rates for the eighth time since late 2015. Investors are also counting on another rate hike before year-end, though the outlook for 2019 is less clear.
Focus will be on the policy outlook and on any comments around the global trade dispute and outlook for growth.
The dollar has benefited from a hawkish rate outlook all year. But in the last few weeks it has lost steam as other economies, such as the euro zone, improved and put them closer to a shift to tighter monetary policy.
The dollar index, which measures the greenback against six major currencies, has slipped around 3 percent since mid-August.
The index was basically flat at 94.134 on Wednesday, sitting near a 2-1/2 month low of 93.814 touched on Friday.
Minori Uchida, MUFG Bank's chief currency analyst, said appetite for risk has somewhat increased as the total impact of U.S. tariffs on Chinese goods remains relatively small.
The United States imposed fresh tariffs of 10 percent on $200 billion worth of Chinese goods on Monday, which will rise to 25 percent at the end of 2018.
"As long as it remains at that level, the impact won't be so big. U.S. stocks are rising. The risk-on sentiment is the main driver that's weakening the yen," Uchida said.
The Australian dollar tacked on 0.3 percent to $0.7272.
The New Zealand dollar advanced 0.4 percent to $0.6674 after a survey showed a surprising bounce in business sentiment in September from a decade low.
Firms' assessment of their own activity also picked up after a tough few months, though they remained pessimistic overall.
Sony senior analyst Kumiko Ishikawa said investors were paying attention to talks between U.S. President Donald Trump and Japanese Prime Minister Shinzo Abe on the sidelines of the United Nations General Assembly meeting in New York later on Wednesday.
