Swedish central bank's Ingves says not seen major liquidity problems after QE

"Our bond purchases have worked well for a long period of time, so we are satisfied," Ingves told reporters.

"We have not seen any big worries."

The Riksbank recently paid a significant premium to buy 2022 bonds in a reverse auction with some analysts pointing to this as evidence of liquidity problems.

Swedbank Chief Economist Anna Breman said in testimony to parliament on Thursday the bond market was under severe strain, with only the Debt Office's repo facility keeping the market liquid.
