Spain's De Guindos says the Eurozone continues to have defects

Econ min speaking to El Pais

• Euro area monetary union continues to have defects stemming from initial design, and challenge to boost the region's potential growth rate
• most immediate risks facing EU are possible Brexit and providing adequate response to refugee crisis
• Eurozone is incomplete

By initial design he is no doubt referring to the fact that original members states made their economic numbers up to meet requirements, and that one size does not fit all

And a shot across the bows of the ECB perhaps that they can't print their way out of trouble
