Ingves said on Tuesday that maintaining low interest rates was critical for the Swedish economy, in order to help inflation rise towards the target levels of 2 percent.
However, he pointed out that low interest rates also increased the risk of high household debt.
"Our judgement is that the measures we have already taken are not enough," the Riksbank general stated. "We need to do more."
Ingves said that immediate measures must be taken in other areas of national policy in order to manage these risks in the housing market.
He also hinted that the national bank's repo rates would climb if politicians and agencies did not take immediate action.
