Norway's rainy day pot of cash has outperformed its own benchmark thanks to the second quarter surge in equity markets.
The $975 billion fund is the largest sovereign wealth fund in the world and is bolstered by revenue from sales of oil.
Nestle, China's Tencent and Swiss company Novartis made the biggest positive contributions as the fund rose by 2.6 percent across the quarter.
Overall stock investments returned 3.4 percent, while fixed income investments returned 1.1 percent. Investments in unlisted real estate returned 2.1 percent.
In a statement Tuesday, Trond Grande, deputy chief executive officer of Norges Bank Investment Management said equities were crucial to the fund performance.
"The stock markets have performed particularly well so far this year, and the funds return in the first two quarters was 6.5 percent.
"This gives a total return of 499 billion crowns ($63.1 billion), which is the best half-year return measured in Norwegian crowns in the history of the fund," he added
Grande noted both the positive effect of currency swings and the outperformance of European stocks to warn that future returns were unlikely to remain so healthy.
