As the super central bank week of September 2026 approaches, the US August CPI inflation data showed a slight decline but remained stickier than expected. Combined with the existing backdrop of Middle East geopolitical conflicts pushing up oil prices and global bond market volatility, market sentiment has completely shifted away from easing expectations. This week, major global central banks are facing a fresh marginal window of comprehensive policy expectation restructuring, with core increments concentrated in three major changes: intensifying Fed gamesmanship, upward revisions to hawkish expectations across multiple central banks, and markets moving in reverse directions.

Latest Marginal Catalysts: The old inflation backdrop is now firmly established, while new risks continue to ferment. The previous lackluster inflation cooling, Saudi Arabia's closure of overland oil pipelines pushing up crude prices, and rising US Treasury yields are all established facts. Recent core increments center on the fresh evolution of risk expectations and policy logic, while raising a key question: is it inflation or high-growth borrowing industries that are driving rates higher.

Core New Developments: Global central bank policy expectations are collectively being revised upward in a hawkish direction. Based on the established inflation and energy fundamentals, the largest recent marginal shift is that the US, UK, Japanese, and European central banks have thoroughly revised their previous easing expectations, simultaneously releasing signals to intensify anti-inflation efforts, forming a new round of global tightening inflection point.

Federal Reserve: A difficult game between political pressure and market credibility. Compared to the previous fixed policy framework, the recent new variable is the intensifying political game at the Fed plus a sharp jump in rate hike expectations. Trump continues to pressure for rate cuts, even threatening trade sanctions, creating extreme political interference against new Fed Chair Warsh — a uniquely new game pattern this cycle. After last week's CPI data landed, market expectations underwent a disruptive revision: the probability of a September Fed rate hike surged from 70% to 90%, with the probability of 50 basis points of cumulative hikes this year rising sharply. Markets have completely abandoned the old expectation of "one-and-done" rate hikes. Institutional incremental views are unanimously bullish on multiple consecutive rate hikes, with restoring Fed policy credibility now the core policy objective. On the incremental signal front, Goldman Sachs has issued a fresh warning about credibility risks of not hiking, while the White House recently released its first easing signal, expressing respect for Fed independence, providing new policy buffer for this rate hike's implementation and significantly reducing policy uncertainty.

Bank of England: Hawkish hold with room reserved for future hikes. The market expectation for unchanged rates is already well established. The recent fresh marginal change is a significant upgrade in hawkish expectations: combined with better-than-expected economic data and new oil price pressures, markets have raised the number of expected rate hikes over the next 12 months from three to four. The mainstream consensus has shifted toward a "hold now, hike continuously later" hawkish stance.

Bank of Japan: Ending deflation and entering the era of 30-year-high interest rates. The BOJ is experiencing the largest marginal inflection point in global policy this cycle: markets are fully pricing in a September hike of 25 basis points to 1.25%, a 31-year high, formally ending the ultra-loose deflationary policy. Combined with explicit US support for hikes and rising yen repair demand, policy normalization is accelerating faster than expected.

European Central Bank: First to deliver hikes, locking in a tightening stance. The ECB's previous rate hike has already landed. Recent fresh incremental statements clearly lock in a medium-to-long-term tightening stance, emphasizing that Middle East conflicts will permanently solidify inflation pressures, completely extinguishing short-term market hopes for rate cuts.

New Market Marginal Impacts and Fresh Landscape: There have been some minor episodes in the AI sector recently. First, amid extremely heated rate hike expectations, US stock futures have strengthened against the trend. The core incremental driver comes from better-than-expected corporate earnings, with markets forming a new pricing logic — that strong fundamentals can absorb multiple rounds of rate hike shocks, and this hike is expected to restore Fed credibility and alleviate upward pressure on long-end Treasury yields. However, top AI pioneers have since supported a warning from an Anthropic researcher about "a significant risk of catastrophic and irreversible loss of control in the near term." Geoffrey Hinton believes a 10% probability of human extinction "seems like a reasonable estimate." Nevertheless, some analysts argue that the current "AI doomsday" narrative has been exaggerated by media, and the real risk lies not in model capabilities themselves but in the "hysteria" that could replace thoughtful deliberation. Trump has also stated that AI development still needs to be vigorously pursued. Musk subsequently posted on social media that Grok 4.8, a model with 2.5 trillion parameters trained on their brand-new C++ software stack, will complete training this week and initiate reinforcement learning. In other words, if AI investment continues unabated, global central bank rate hikes can be absorbed by the high growth driven by the AI industry. But if AI slows down at this point, a crisis could emerge.

On the liquidity front, this round of synchronized hawkish turns across multiple nations forms a globally synchronized liquidity tightening inflection point not seen since 2006. Global financing costs are beginning a systematic upward trend, continuously suppressing the pace of global economic recovery. Geopolitical economic games have also escalated to a new level. The persistent confrontation between the Fed's anti-inflation hikes and the White House's rate cut demands has made monetary policy independence a fresh market focus. The linked pricing logic among geopolitics, energy, and central bank policy has significantly strengthened.

Forward Outlook: Tightening expectations continue to be revised upward. Overall, previous data points such as CPI, inflation, and geopolitical shocks are already fully priced in. The core of this round of market movement lies in the fresh marginal restructuring of policy expectations, market pricing, and game patterns. The global tightening cycle continues to lengthen, but the ultimate market impact depends on whether a narrative sustaining high growth can emerge. The core trading themes going forward are all new variables: expectations for consecutive Fed rate hikes, accelerated gradual tightening by the BOE and BOJ, and real-time marginal fluctuations in Middle East tensions and oil prices. These will continue to dominate global asset pricing, further deepening the new market landscape of high interest rates and sticky high inflation.
