The Saudi Central Bank publishes reserve totals, not portfolios. What it holds abroad becomes visible mainly through other governments’ disclosure rules, and this week two of them reported at once. US Treasury data for June puts the Kingdom’s holdings of American government debt at $142.5 billion, up 1.6 percent on the month and 9.2 percent on the year, the seventeenth largest position in the world and the largest in the Gulf and the wider Middle East. Filings with the US securities regulator for the second quarter show SAMA’s disclosed US equity portfolio at $7.63 billion, up 61 percent in three months.
The Treasury book is built for ballast. Seventy-six percent of the position, $108.6 billion, sits in long-term securities, with $34 billion in short-term paper. The June total remains below the February peak of $160.4 billion, but the year-on-year direction is accumulation, and it runs against the tide: foreign holdings of Treasuries overall slipped 0.8 percent in June to $9.3 trillion. Japan remains the largest holder at $1.12 trillion, with the United Kingdom and mainland China behind it. The UAE, at $114.8 billion, ranks nineteenth.
Scaling a Sleeve
The equity book moved differently. SAMA raised its position in 474 of the 493 securities it discloses, and in 349 of them the increase fell between 85 and 90 percent. Micron Technology became the largest single holding at $438 million; a semiconductor exchange-traded fund is second at $335 million; Nvidia, after an 80 percent increase to 1.62 million shares, stands at $323 million, with Apple at $297 million. Microsoft, Amazon, Alphabet and Broadcom all grew between 80 and 91 percent. The new names are small and pointed: TotalEnergies at $42 million, and a $6.3 million position in SpaceX.
The uniformity is the signal. Raising nearly every position by a similar fraction is how an institution scales a mandate, funding the sleeve and buying pro rata, rather than how a stock picker expresses views. The decision that mattered was the size of the allocation, roughly $2.9 billion added in a quarter. The composition then does the positioning: with semiconductors as the two largest holdings and the platform companies behind them, the reserve manager’s equity sleeve leans on the hardware layer of the AI cycle.
Two Books, One Balance Sheet
Read beside the Public Investment Fund’s annual report, published a day earlier with 80 percent of its assets inside the Kingdom, the filings sketch the architecture of the national balance sheet. PIF concentrates at home, in development assets that pay off in sectors and jobs. SAMA holds the external side: liquid, dollar-denominated and dominated by government paper, with an equity sleeve that even after the quarter’s expansion amounts to about five percent of the Treasury position. Growth in both books over the same period is the combination that stands out; reserves and development capital are accumulating together rather than being traded against each other.
July’s Treasury data arrives in mid-September and the next equities filing in November. The readings to watch are whether the equity sleeve keeps scaling at this pace, whether the short-term share of the Treasury book drifts as US rate policy turns, and whether the February peak is retraced. Central banks disclose little and explain less; the filing calendar will keep answering in their place.
