Norway’s sovereign wealth fund raked in a return of round 1.028tn kroner, or $131bn, in 2017 thanks to global stock market rallies, which let its profits swell to around one-third of its home-country’s gross domestic product in 2017, MarketWatch reports.

This measures the third consecutive year of growth for the government pension fund measured in international currencies. In Norwegian kroner, the returns have only risen for two years in a row. The fund’s market value climbed by 13% to Nkr8.488tn last year ($1.08tn), after surpassing the equivalent of $1tn for the first time in September last year, according to the fund’s annual report.
