The European Central Bank may need to raise interest rates again if wages, profits or new supply snags boost inflation, ECB board member Isabel Schnabel said in an interview published on Friday.
The ECB raised borrowing costs to record highs last month to rein in prices in the euro area, which are still growing at more than twice its 2% target after the bloc was hit by higher energy prices and supply snags last year.
Schnabel said a recent moderation in inflation, which fell to its lowest level in two years at 4.3% in September, was "encouraging" but risks abounded, from stronger-than-expected wages or profits to new disruption to supply.
"I still see upside risks to inflation," Schnabel told Croatian newspaper Jutarnji list. "If they materialise, further interest rate hikes could be necessary at some point."
The ECB pushed the rate it pays on banks' deposits to the highest in its 25-year history at 4.0% last month in a bid to cool lending and, with it, consumption and investment.
Some policymakers have therefore been pushing to raise the proportion of unremunerated reserve requirements that banks must hold as part of their next stage of their fight against inflation.
But Schnabel played down the chances of such a move in the near term.
"We are currently discussing the design of our future operational framework for monetary policy implementation," she said. "As long as we do not know the role that minimum reserve requirements will play in this new framework, we should be cautious about making any far-reaching decisions."
