ZURICH, Aug 31 (Reuters) - The Swiss franc's recent weakening against the euro is a positive development but the trend was "fragile", Swiss National Bank governing board member Andrea Maechler said on Thursday.
The franc has lost ground against the euro in recent weeks as the eurozone's economy has shown signs of improvement and political uncertainties have cleared.
"Overall, the trends are pointing in the right direction for the Swiss franc, but it is too early to say whether these trends are sustainable," Maechler told an economic conference in Yverdon-Les-Bains.
"The situation remains relatively fragile."
