Riksbank Governor Stefan Ingves said that Sweden’s central bank could pump more money into the economy  through lending and/or start charging depositors with so-called negative rates, Reuters reports.

“The Riksbank has … previously demonstrated that it is fully possible to substantially expand the balance sheet,” Ingves said.

The central bank cut rates to a record low of zero in October and held them there in December when it said rates would stay low for longer and it was ready to adopt unconventional measures if needed.
