PRAGUE The timing of future interest growth in euro zone is a matter of the state of the economy, member of the European Central Bank Governing Council Jozef Makuch said on Tuesday.

Asked at a news conference about reaction to a possible economic slowdown, Makuch said that such scenario could create need to reformulate the ECB's forward guidance.

The ECB's Governing Council has pledged last week to maintain rates at their record low levels at least through next summer. It also agreed to stop new bond purchases after nearly four years, however it would keep its stock of debt stable for a long time.
