Norway's sovereign wealth fund, the world's largest, made a loss of 1.68 trillion Norwegian crowns ($174 billion) in the first half of 2022, it said on Wednesday, as stocks and bonds were hit by global recession fears and rampant price inflation.

The $1.3 trillion fund's return on investment was a negative 14.4% for the January-June period, although that was 1.14 percentage points ahead of the return on its benchmark index.

"The market has been characterized by rising interest rates, high inflation, and war in Europe," said Chief Executive Nicolai Tangen of Norges Bank Investment Management, which operates the fund, in a statement.

"Technology stocks have done particularly poorly with a return of minus 28%," he said.

Founded in 1996, the fund invests revenue from Norway's oil and gas sector and holds stakes in more than 9,300 companies globally, owning 1.3% of all listed stocks.

Its $1.3 trillion valuation approximately equates to the size of the Mexican economy, the world's 16th largest, according to some measures.

All sectors in which the fund invests recorded negative returns in the first half, apart from energy, where returns were 13% as prices soared following Russia's invasion of Ukraine.

Central banks have hiked interest rates aggressively this year to combat inflation, leading to increased borrowing costs and lowered profit margins for corporations.

The tech-heavy Nasdaq Composite and the broader S&P 500 index saw their biggest January-June declines since the financial crisis, while U.S. and European government bond markets had their worst start to any year in decades.

In total, 68.5% of the fund was invested in equities at the end of June, with 28.3% in fixed income, 3.0% in unlisted real estate and 0.1% in unlisted renewable energy infrastructure.
