On Thursday, July 30th, financial markets faced two mutually reinforcing pricing drivers. On one hand, the Federal Reserve maintained the target range for the federal funds rate at 3.50% to 3.75%, but three of the 12 voting members advocated for a 25 basis point rate hike, indicating a significant widening of policy divergence. On the other hand, the latest earnings reports from Microsoft and Meta showed that while investment in artificial intelligence infrastructure continued to grow, the cash flow resilience of different companies had diverged significantly. The combination of interest rate uncertainty and capital expenditure pressure shifted market focus from revenue growth to duration, cash flow, and capital return efficiency. The interest rate decision itself was not unexpected; the key issue was the lack of a stable anchor for policy signals. The Fed statement indicated that economic activity remained relatively stable and expansionary, with job growth roughly in line with labor supply, but inflation remained above the 2% target, and supply shocks in sectors such as energy continued to exert price pressure. The fact that three members called for an immediate rate hike signifies a substantial split within the committee regarding the assessment of inflation risks and the lagged effects of policy. Federal Reserve Chairman Kevin Warsh recently emphasized that the market should rely more on economic data than on continuous waiting for central bank guidance, and stated that policymakers "will not hesitate to act" if price pressures do not ease. The problem is that reducing forward guidance does not diminish the central bank's weight in interest rate pricing. Short-term interest rates are essentially still driven by market judgments of future policy paths; reduced communication only widens the probability distribution of different scenarios, rather than removing policy factors from the pricing framework. The probability of a September rate hike rose to 77% after the meeting, then fell back to about 57% to 60%, indicating that the market did not receive clearer information but rather switched rapidly between different interpretations. After the policy announcement, short-term Treasury yields initially declined, while long-term yields rose significantly. The 30-year Treasury yield touched 5.2273%, the highest level since June 2007, and the 10-year yield rose by nearly 27 basis points cumulatively in July. The simultaneous decline in short-term yields and rise in long-term yields creates a typical steepening of the yield curve. This structure cannot be simply interpreted as the market expecting an imminent Fed rate hike. The decline in short-term yields indicates that some funds believe maintaining interest rates unchanged reduces the probability of immediate tightening, while the rise in long-term yields reflects a simultaneous increase in inflation risk premiums, term premiums, and fiscal financing compensation. In other words, the market is not only concerned about whether there will be a rate hike at the next meeting, but also whether the Federal Reserve might be forced to take stronger measures in the future due to its slow response. This has a non-linear impact on asset valuations. A rise in long-term risk-free rates directly increases the discount rate for equity cash flows and also pushes up long-term financing costs for companies. Even if short-term yields remain stable temporarily, overvalued assets may still be under pressure due to terminal value discounting and risk premium revaluation. Therefore, the core contradiction in the current trading environment has shifted from simply speculating on policy direction to judging the sources of risk reflected in different maturities of the yield curve. Rising interest rates and the expansion of capital expenditures for artificial intelligence are not two independent threads. Rising long-term yields mean higher funding costs and a lower present value of future corporate cash flows; increased capital expenditures will depress current free cash flow, making valuations more sensitive to long-term growth assumptions. When both occur simultaneously, the market will increase its demands for the speed of revenue realization, asset turnover efficiency, and profit margin stability. Going forward, the market may focus on observing three variables. First, can inflation data reduce the volatility of expectations for a September rate hike? Second, is the rise in long-term yields a short-term risk shock or a sign that the term premium has entered a sustained upward phase? Third, can large technology companies cover infrastructure investments with cloud service revenue, order backlog, and operating cash flow? If revenue growth remains stable but free cash flow continues to deteriorate, capital expenditure will shift from a growth narrative to a balance sheet constraint.
