The European Central Bank (ECB) said on Thursday that banks borrowed €15.5 billion in loans, the so-called TLTROs.
The ECB is offering banks the loans as part of its stimulus measures to spur Eurozone's economy and to boost inflation to its 2% target.
The ECB said there were 88 bidders (June: 28) for this week's TLTROs.
Banks borrowed €73.8 billion in June, €97.8 billion in March, €129.8 billion euros in December 2014 and €82.6 billion in September 2014.
