The Norges Bank kept its rates on hold at 0.5 percent last week, despite concerns over increasing house prices. But Olsen refused to answer questions on whether its era of ultra-loose policy was coming to an end.
"As a result of Brexit there are new challenges for Britain, politically but also in the economic area … Looking forward I choose to be optimistic on behalf of the British economy, but there are a number of matters that need to be arranged," Olsen said, mentioning new trade deals as example.
Norway has a few economic issues of its own to fix. The Norwegian economy has suffered a severe setback on the back of falling oil prices, reaching a GDP (gross domestic product) rate of 1 percent in 2015 – the lowest since the financial crisis.
"The declines in oil prices and offshore investment have taken a toll on the Norwegian mainland economy," the International Monetary Fund said in a report last July.
According to IMF projections, Norway should register growth of 1.1 percent this year and 1.7 percent in 2017.
"A recovery should take root in 2017 alongside a gradual upturn in oil prices and a slowing of the pace of decline in oil investment," it added.
