STOCKHOLM: The first ever purchases of corporate bonds by Sweden's central bank have gone roughly as planned, Riksbank Governor Stefan Ingves said on Tuesday.

"We didn't buy much last week. It went basically as we had expected, given that the market has its peculiarities and does not work like the government bond market or the mortgage bond market," Ingves told reporters after the central bank held policy unchanged.

The central bank has said it will buy up to 10 billion Swedish crowns ($1.13 billion) in corporate bonds as part of its 500 billion crown quantitative easing package.

It bought 150 million crowns last week, according to information on the Riksbank's home page.
