TOKYO, July 1 (Reuters) - The dollar held steady against the euro on Wednesday ahead of data expected to show U.S. manufacturing activity and hiring continued to recover from the economic shock caused by the coronavirus pandemic.
The euro was hemmed into a narrow range as traders awaited data on Germany's manufacturing sector, retail sales, and the jobless rate to gauge the health of the eurozone economy.
The yen firmed slightly on safe-haven flows after a top government spokesman said Japan could re-impose a state of emergency in response to the coronavirus.
A surge in new infections in the U.S. south and southwest has worried some market participants, but most investors are betting this will not be enough to derail a broader rebound in the global economy.
"The dollar will be supported against the yen if U.S. economic data are positive, but U.S. yields are not rising much because of speculation about yield curve control," said Shusuke Yamada, head of foreign exchange and Japan equity strategy at Merrill Lynch Japan Securities.
"The euro looks stable, but there are questions about Brexit and the pace of economic reopening, which means the euro could soon be overvalued."
The euro held steady at $1.1223. Against the British pound, the common currency traded at 90.77 pence following a 0.9% decline on Tuesday.
The yen edged up to 107.63 per dollar, pulling back from a three-week low.
The yen barely reacted after Bank of Japan data showed business sentiment fell to an 11-year year low.
Sterling bought $1.2367, surrendering some of the previous day's gains due to worries about Britain's trade negotiations with the European Union.
The U.S. Institute for Supply Management's purchasing managers' index (PMI) for manufacturing due later on Wednesday is forecast to show that activity in June continued to recover from an 11-year low marked in April, when the coronavirus paralysed large swathes of the global economy.
Investors also await the closely-watched U.S. nonfarm payrolls report on Thursday, which is expected to show the economy added 3 million jobs in June.
The onshore yuan was little changed at 7.0654 per dollar after the People's Bank of China cut the re-discount and re-lending rates to reduce funding costs for small firms.
Some investors are wary of diplomatic tensions over Beijing's new security law for the former British colony of Hong Kong, which came into effect on Wednesday.
The dollar has failed to make headway against commodity currencies recently, showing that some investors remain wary of downside risks.
Normally Treasury yields would rise due to an improving economy, but benchmark 10-year yields have moved in a narrow range around 0.65% since mid-June, when Federal Reserve Chairman Jerome Powell said policymakers discussed yield curve control, which can be used to cap bond yields.
The Australian dollar bought $0.6891 on Wednesday following a 0.5% gain on Tuesday.
The New Zealand dollar stood at $0.6443, also holding onto gains from the previous session.
The Swiss franc, a currency traditionally sought as a safe haven during times of heightened risk, also perked up against the greenback, which shows that positive economic data alone is not enough to support broad-based dollar gains.
The euro has lacked conviction amid mixed signals about the eurozone economy and limited progress in talks on the future trade relationship between Britain and the EU.
Data due later on Wednesday from Germany are expected to show retail sales in Europe's largest economy fell at a slower pace but the manufacturing sector continued to contract, which could hurt sentiment for the euro. (Editing by Sam Holmes and Jacqueline Wong)
