The euro remains near 11-month lows against the US dollar as European debt concerns continue to focus on Portugal.
With the Portuguese government due to auction 500m euros ($651m; £418m) of bonds later, analysts are waiting to see the extent of market interest.
It comes a day after ratings agency Standard & Poor’s placed Portugal on credit watch due to the country’s huge debts.
Meanwhile, Portugal’s central bank warned of the risks facing its banks.

It said they faced an “intolerable risk” if the government in Lisbon failed to consolidate public finances.
In early Wednesday trading, the euro was up slightly to $1.3020 from its Tuesday low of $1.2969.
Meanwhile, on the bond markets, the yield on Portuguese bonds was stable at 6.97%.
The higher the yield, the less confidence investors have in the bond.
The yield on German bonds remained around 2.67%.
With the Republic of Ireland getting a European Union-led bail-out last week, the concern in some quarters is that Portugal may be the next country that needs assistance.
“The general feeling is that this is a mess that is not going to be easily escaped,” said analyst Robert Ryan of BNP Paribas in Singapore.
