最新报道：Welcome to the US Crypto Morning Briefing—your essential summary of the day's most important cryptocurrency developments. Grab a coffee, because the world's largest sovereign wealth fund just quietly but dramatically entered Bitcoin (BTC). While the details are subtle, the impact could be anything but. Today's Crypto News: World's Largest Wealth Fund Boldly Increases Bitcoin Holdings by 83%. Norway's sovereign wealth fund, the world's largest, has significantly increased its Bitcoin exposure amid a quiet but notable institutional shift toward the pioneering cryptocurrency. Norges Bank Investment Management (NBIM) increased its Bitcoin equivalent holdings by 83% in the second quarter (Q2) of 2025. Notably, NBIM manages Norway's $1.6 trillion oil fund portfolio. The fund's exposure increased from 6,200 BTC equivalents to 11,400. The majority of NBIM's Bitcoin exposure is indirect, through shares of MicroStrategy (MSTR), the largest corporate Bitcoin holder. Despite this, NBIM initiated a smaller position in Japan's Metaplanet, equivalent to 200 BTC. Geoff Kendrick, head of digital asset research at Standard Chartered, noted the significance of this move in a statement to BeInCrypto. While NBIM did not make any public announcement regarding the increase, the move comes amidst broader institutional participation in Bitcoin through listed stocks and ETFs (exchange-traded funds). Sovereign wealth funds, in particular, have long been viewed as strategically prudent investments for the long term, making such a significant increase in exposure noteworthy. The timing also aligns with the steady rise in Bitcoin prices over the past quarter. Positive factors include strong ETF inflows and growing adoption by corporations and governments. Other factors include macroeconomic uncertainty. For NBIM, whose mission is to ensure long-term returns for future generations of Norwegians, the Bitcoin allocation represents only a small portion of its overall assets. However, as recently noted in US cryptocurrency news publications, it may be a strategic hedge against currency devaluation and geopolitical risks. NBIM's latest move may not be an isolated incident. Industry analysts point to a growing trend among sovereign wealth funds and large pension fund managers. As BeInCrypto has reported, some of these institutions are quietly exploring Bitcoin as part of a diversified, long-term portfolio. If this trend continues, these quiet but decisive allocations could outpace Bitcoin's liquidity profile and institutional credibility. This shift could mark the early stages of sovereign-backed Bitcoin adoption. Today's Charts Here's a rundown of more US cryptocurrency news to watch today: Crypto Stock Pre-Market Overview
