Global markets are currently facing three mutually reinforcing reflexivity loops: oil price politics, massive capex from hyperscale cloud providers, and AI debt risks. Goldman Sachs warns that the combined negative feedback mechanism formed by these three factors leaves the current market in a fragile and precarious balance.
This week, Rich Privorotsky, head of 1-Delta Trading at Goldman Sachs, pointed out in his latest client report that the dual pressures of soaring oil prices and rising interest rates are making the market increasingly difficult to digest, and the negative shock on the bond side has deteriorated sharply.
He stated that without substantive easing at the political level, the market will have to absorb the risks on its own, pushing the situation towards a worse direction.
At the same time, the uncontrolled expansion of capital expenditures by tech giants and the price collapse of AI infrastructure-related bonds are shaking investor confidence in the hyperscale cloud provider narrative.
Privorotsky warns that betting on these companies is essentially evolving into a high-stakes gamble on "the revenue inflection point arriving before the peak in expenditures."
The two-way feedback mechanism between oil prices and politics is the first reflexivity chain Privorotsky is most concerned about.
Brent crude oil prices briefly broke through $100 per barrel this week, testing market expectations regarding Trump's policy responses.
Previously, the market generally expected that once oil prices breached a certain threshold, pushing up retail gasoline prices and dragging down presidential approval ratings, the Trump administration would intervene to curb oil prices.
This expectation has supported stock market resilience to some extent, but Privorotsky pointed out that each day that passes without a policy response at the same price level forces the market to drive the outcome itself.
The interest rate shock is becoming the most difficult variable to ignore in this loop.
Meanwhile, the transmission of energy costs into food inflation is also about to become a reality.
Warning signals have already appeared at the real economy level—despite record-high revenues, rising ticket prices, and relatively robust demand, American Airlines still lowered its 2026 performance guidance, citing that its fuel costs have increased by about $1.6 billion since early July.
Geopolitical tensions continue to heat up.
According to CCTV News, on July 24 local time, when discussing the "exit strategy" for the war with Iran at the White House, President Trump stated that the US has two choices: first, continue current military operations, possibly intensifying strikes, and gradually destroy Iran's military capabilities; second, reach an agreement through negotiations.
Wall Street Insights mentioned that earlier that day, Reuters cited sources reporting that Pakistan is exploring ways to push for the resumption of stalled US-Iran negotiations.
Israeli Prime Minister Netanyahu will visit the White House to meet with Trump next Tuesday. Privorotsky suggests this timing may be brewing a "TACO moment" for the market—a sudden negotiation or compromise-driven market movement.
The second reflexivity loop revolves around the capital expenditures of hyperscale tech companies, with its core contradiction being: is the market still willing to view massive investments as growth signals with no cost?
Google became the negative symbol of this earnings season for tech. The company announced an increase in its 2026 capital expenditure guidance to $195-205 billion, with free cash flow for the quarter at negative $5.9 billion, and its stock price subsequently fell by 6.9%.
While operational data such as 82% growth in cloud business was impressive, the market is no longer willing to view expenditures as cost-free strategic investments, and questions about cutting-edge product roadmaps and return on investment received almost no positive response.
The deeper impact lies in competitive transmission. If Google increases spending, it will force peers to follow suit, putting pressure on the entire hyperscale cloud computing sector. The hardware side is also sounding alarms:
- STMicroelectronics' core profits missed expectations, and Q3 revenue guidance appeared slightly weak, with the stock falling about 14%;
- Texas Instruments (TXN) performed relatively solidly but still closed down 3%.
Regarding the competitive landscape in artificial intelligence, Privorotsky pointed out that the gap between leading closed-source models and Chinese open-source models has narrowed significantly.
He stated that the gap, previously measured in nine to twelve months, has now compressed to weeks on some benchmarks. The cost-to-marginal-benefit ratio of pre-training versus reinforcement learning and post-training is creating vastly different economic models; the intensity of competition at the application layer and the flatness of the competitive landscape are historically rare.
He believes that the risks from small models and efficiency improvements are a "story for later," but should not be underestimated.
The third reflexivity loop is hidden within the bond and financing structures of hyperscale tech companies.
Privorotsky views the bond market as the most noteworthy risk signal at present.
Taking Meta's "Hyperion" financing of $27.3 billion completed through the Beignet SPV as an example, this bond issuance was priced at par and later traded above 109, but has now fallen back to around 95.
Although the overall financial health of hyperscale cloud providers remains robust, with balance sheet leverage not high, the impact of valuation repricing on stock multiples has been quite significant.
The more severe problem is that as capital expenditures accelerate, free cash flow conversion continues to deteriorate, and the impact on leveraged entities providing financing for infrastructure construction will be even more drastic.
Privorotsky warns that today's capacity expansion could evolve into tomorrow's computing power oversupply, and at that time, larger-scale depreciation expenses will begin to wash over the income statement.
Looking ahead to the near term, Privorotsky named two events that will serve as crucial tests for the aforementioned reflexivity themes.
The first is Microsoft's earnings conference call this Wednesday. He believes, "If the reflexivity theme is to play out, this might be the most crucial call."
The market will closely scrutinize Microsoft's balance between capital expenditures, cloud growth, and free cash flow to judge whether the hyperscale tech narrative can stabilize.
The second is the IPO of Chinese memory chipmaker ChangXin Memory on the STAR Market. ChangXin Memory is currently the world's fourth-largest DRAM producer, and this fundraising round amounts to approximately $8.6 billion.
Privorotsky emphasized, "This is by no means an insignificant new competitor." If its post-IPO stock price trades close to the valuation levels implied by the OTC perpetual market, it will have a significant impact on the entire memory chip sector.
Privorotsky concluded with a sentence summarizing the current situation:
It feels a bit like circular referencing on the oil price issue.
In a market dominated by reflexivity, every variable is both cause and effect.
