How sparsely populated Norway amassed $1.8 trillion

Of all the world’s sovereign wealth funds, Norway’s is one of the most unusual. These giant, state-linked investment vehicles tend to pick and choose what assets they hold to manage risk, maximize returns and further national strategic interests. Not so with Norges Bank Investment Management, which largely tracks global indexes in order to generate an income from the country’s oil and gas revenues.

Launched in the early 1990s to invest mostly in bonds, the fund has grown to become the largest of its kind by acquiring small equity stakes in thousands of companies across the world. 

With $1.8 trillion of assets, the fund now generates far more income for the Nordic country’s 5.6 million population than oil and gas production. There are growing concerns that the economy has become so dependent on the income from the fund that domestic industries are becoming less innovative and dynamic as a result.

There’s also been criticism of the fund’s passive approach to investing the nation’s wealth, which leaves it with few tools to adapt to the ebb and flow of global capital. This was underscored in April when it reported its biggest loss in six quarters amid the market turmoil unleashed by US President Donald Trump’s threatened trade tariffs.

The fund stands apart from many of its peers due to its strict investment rules. Firstly, it must always invest outside Norway — a rule designed to avert the risk of “Dutch disease,” where resource wealth can end up destabilizing the domestic economy by inflating the local currency and making it harder for other national industries to compete.

Norway discovered significant oil and gas reserves in the North Sea in 1969, and today is western Europe’s largest producer of the fossil fuels. Anxious to avoid the instability, corruption and weak economic growth experienced in other resource-rich economies, the government imposed heavy taxes on the energy sector and placed strong regulatory controls on the industry. In 1990, after years of political debate, Norway’s parliament created the Petroleum Fund to ensure that oil revenues would benefit current and future generations. The first capital transfer to the fund was made in 1996.

When comparing its investment returns with those of other sovereign wealth funds, the Norwegian fund achieved a relatively average performance over the five years to 2023, returning 7.45%, according to research consultancy Global SWF. That’s less than Abu Dhabi fund Mubadala, at 10.1%, and China Investment Corporation, with 8.6%, but higher than the 4.5% return for Singapore’s Temasek and 5.2% for the Korean Investment Corporation.

Since 2004, the fund has operated under ethical guidelines set by the finance ministry and approved by parliament. An independent Ethics Council oversees the guidelines, which prohibit investments in companies involved in “gross corruption” or serious violations of human and labor rights, or that contribute to severe environmental damage. They also exclude companies that produce certain weapons, such as nuclear arms and cluster bombs.

Some of the wealth fund’s available profits go to support Norway’s extensive welfare system, which provides free education and health care, subsidized child care and generous sick leave. Norway ranks third on the UN’s global Human Development Index, after Iceland and Switzerland. In 2024, transfers from the fund accounted for roughly 20–25% of the national budget.

The fund has been a financial buffer that enabled the country to weather fluctuations in oil prices and the economy and maintain the country’s fiscal stability.  The fund has furthered Norway’s soft power by promoting sustainable business practices worldwide.

Yet there’s a debate about how reliant Norway has become on the money generated by the fund. Critics say it’s making the country’s political leaders complacent and its population less productive. They point to data showing national productivity has worsened relative to other wealthy nations in the past two decades. The government is spending growing sums to subsidize sick leave for workers, and student test scores have been on a downward trend.
