Sentiment for the euro has worsened dramatically this month after weak manufacturing and gross domestic product data from Germany, Europe's largest economy, suggests that the euro zone is more vulnerable to external shocks that previously thought.
"The euro is close to testing an important support level at $1.08 due to the diverging economic outlook between the euro zone and the United States," said Junichi Ishikawa, senior foreign exchange strategist at IG Securities in Tokyo.
"It looks a little oversold, so in the very short term there could be a bounce, but the euro's fundamentals still point more to the downside."
The euro was quoted at $1.0836 in Asia, close to its lowest since April 2017.

However, currency markets are increasingly likely to react to new data on the virus cautiously given uncertainty about the actual number of cases and difficulties in estimating when the epidemic will peak.
The yen, which initially gained on safe-haven flows as the outbreak unfolded last month, held steady in a narrow range at 109.82 per dollar.
