According to insights from trading desks and detailed minutes from JPMorgan's strategy research division, the firm's global macro conference delivered a pivotal message that can be distilled into a single core idea: stocks and US Treasury yields have the capacity to climb simultaneously, at least for the present moment. The central banks around the world, with the Federal Reserve at the forefront, may be compelled to raise interest rates at a pace and magnitude exceeding what market participants currently anticipate.
The comprehensive report reveals that 15 macro and market speakers engaged in deep discussions covering the US economic outlook, Fed policy trajectory, AI-driven capital expenditures, and geopolitical risks, ultimately converging on two high-conviction conclusions.
First Major Theme: Central Banks May Need to Tighten Faster and More Aggressively Than Expected
JPMorgan's global economists have categorized the upcoming September FOMC meeting as the starting point for a new cycle of rate increases across developed markets. Projections indicate that the Fed, European Central Bank, Bank of Japan, and Reserve Bank of Australia will all take action within the month, with eight of the nine developed market central banks they track expected to implement hikes before the end of 2026. The economists' analysis suggests that a balanced Taylor rule points to developed market policy rates needing to rise by approximately 100 additional basis points, yet the risks are distinctly tilted toward an even faster and larger trajectory.
Second Major Theme: Both Stocks and Bond Yields Can Rise Together
JPMorgan's equity strategists have set a year-end target of 8000 points for the S&P 500, noting that current positioning is light rather than extremely overweight, and valuations have not yet reached extreme thresholds. AI-driven capital spending combined with resilient earnings growth forms the foundational support. Notably, none of the conference participants expressed bearish views on equities, with skeptics being described as an endangered species within this market cycle.
Furthermore, the upward movement in long-end yields represents a global structural trend driven by fiscal deficits, treasury issuance volumes, and term premiums, with total US debt now reaching approximately $40 trillion. The conference minutes also addressed AI bottlenecks, associated risks, geopolitical tensions, and the approaching US midterm elections. This gathering took place on September 10, 2026, in New York, bringing together 15 speakers who examined the US economic outlook, Fed policies, AI investment and productivity effects, geopolitical uncertainties, and midterm election implications.
Rate Hike Pathways: Market Pricing May Significantly Underestimate Tightening Intensity
The report highlights that current developed market yield curves price in approximately 100 basis points of modest tightening, which essentially represents merely unwinding the 2025 rate cuts rather than launching a broader and faster hiking campaign. Market expectations assume roughly 25 basis point increases per quarter, justified by the belief that inflation stems from supply-side shocks rather than wage-driven pressures, with weaker labor bargaining power and lower-than-expected energy shock transmission.
However, conference speakers explicitly identified that risks surrounding this baseline scenario lean substantially toward a faster and larger direction, supported by several critical factors. There exists a potential misjudgment regarding the Fed's neutral rate positioning. The central bank's assertion that current policy rates sit well below neutral contradicts findings from the New York Fed's primary dealer survey, which places nominal neutral rates between 3.0% and 3.25%. The gap between policy rates and neutral levels may be considerably narrower than official narratives suggest. Should labor markets strengthen further, Iranian conflicts persist, or price pressures broaden, short positions at the short end of the yield curve could be reinforced.
Structural stickiness in inflation exceeds what forecasting models can capture. Multiple speakers emphasized that no single inflation indicator simultaneously reflects the level, breadth, and persistence of price pressures. Common metrics such as core PCE, trimmed means, and sticky price inflation share a fundamental limitation: they infer underlying inflation solely from inflation data itself, overlooking vital signals from labor markets, wage growth, productivity, and inflation expectations. Notably, unit labor cost inflation has averaged 2% over the past four years but only 1.5% in the last year, while average hourly earnings growth sits at its lowest level in seven years alongside productivity growth reaching its fastest pace in a decade. After productivity adjustments, wage growth aligns with the 2% inflation target, suggesting underlying inflation may be closer to target than headline figures indicate.
The challenge lies in the fact that substantial current inflation sources remain insensitive to interest rates. The AI construction boom generates near-term inflationary pressures through massive data center capital expenditures that pull demand forward, visible in PCE chip and software prices, capital expenditure data, and credit markets alike. JPMorgan economists have raised their developed market core inflation forecasts by an average of 0.5 percentage points, projecting the Fed will increase its 2027 core PCE forecast by 0.5 points to 2.6% from the December SEP level, while the ECB similarly lifts its 2027 core inflation projection from 1.9% to 2.6%.
Regarding the pace of hikes, history demonstrates that no cycle has ever concluded with a single isolated increase. Several speakers noted that if the Fed openly discusses rate hikes, markets should prepare for sustained action across multiple meetings. Additionally, upcoming BEA revisions to core PCE calculation methodologies lead some speakers to prefer waiting until December before acting, avoiding the risk that September hikes could be offset by subsequent data revisions.
The Logic Behind Simultaneous Stock and Bond Yield Gains
The conference's central narrative systematically challenges the traditional intuition that rising interest rates inevitably suppress equities. Speakers presented multi-dimensional arguments supporting the sustainability of synchronized gains in stock prices and bond yields.
The interest rate transmission channel has undergone structural weakening. Compared to previous hiking cycles, higher policy rates are transmitting with considerably less force to the US real economy, representing the most significant structural shift in this cycle. AI, healthcare, and services now occupy larger, less rate-sensitive shares of growth and capital expenditure, rendering traditional interest rate constraints substantially less effective. Fed policy changes consequently exert far less influence on corporate behavior than in prior cycles.
This transformation means the Treasury yield threshold capable of breaking the stock market's equilibrium may be considerably higher than historical expectations, potentially ranging between 5.5% and 6.0%. The market's current fear threshold has shifted upward from 5% to 5.5%, with 6% now viewed as truly terrifying territory, despite the S&P 500 having delivered substantial gains during the 1990s when rates fluctuated between 6% and 7%. Analysis of 70-80 years of historical data indicates that approximately 5.5% yields remain compatible with the current robust earnings growth environment.
Equity market support remains solid with non-extreme positioning. JPMorgan equity strategists maintain their 8000 point year-end S&P 500 target, supported by strong third-quarter earnings prospects and light rather than extremely overweight positioning, contradicting commentary suggesting markets are excessively optimistic. When the S&P trades at 7600, investors show a consistent preference for buying dips rather than chasing rallies. Semiconductor and AI bottleneck-related stocks also demonstrate valuations that have not reached extreme levels on price-to-earnings metrics.
AI capital expenditure constitutes the core narrative of the current earnings season. Consensus forecasts indicate AI capital spending reaching approximately $900 billion by the end of 2026 and exceeding $1.2 trillion by the end of 2027, with hyperscale cloud providers expected to account for roughly 87% of total AI capital expenditure in both years. For 2026 alone, the five major US hyperscalers have provided capital expenditure guidance exceeding $750 billion, with 2027 projections surpassing $1.1 trillion, and total AI capital spending expected to reach $5.5 trillion before 2030.
The Pace of Rate Increases Matters More Than Absolute Levels
Speakers repeatedly emphasized that the speed and volatility of rate increases carry greater destructive potential than absolute levels. An orderly 100-200 basis point rise can be absorbed without breaking the AI investment theme, but rapid increases would pressure risk assets and force capital expenditure reassessments. A 50-75 basis point increase in long-end rates may produce smaller impacts on overall consumption than a sharp equity market correction, with consumption pressures becoming more evident only beyond 100 basis points.
As an example, the 10-year Treasury yield has risen 90 basis points since April, yet because this occurred over roughly six months in a relatively orderly fashion, markets have largely digested the movement. By contrast, historically rapid increases exceeding 50 basis points in short periods, particularly when combined with geopolitical shocks or dollar strength, have triggered sustained capital outflows.
Long-End Yield Rises Reflect a Global Fiscal Story
The current upward movement in long-end yields fundamentally represents global fiscal expansion rather than purely AI or inflation narratives. European long-end yields have risen in tandem despite Europe's clear lag in AI innovation, undermining explanations that attribute AI as the primary driver. New York Fed surveys of primary dealers show term premiums have climbed from negative territory a decade ago to approximately 125 basis points, driven primarily by market concerns over long-term fiscal sustainability, including the $40 trillion in nominal US government debt.
Currently, US interest payments consume approximately 14% of the federal budget and continue rising. Historically, sovereign debt crises typically emerge when interest payments reach 20%-25% of fiscal budgets, leaving some buffer room, but the pressure direction remains clear.
AI's True Constraints: Permitting and Execution Quality Rather Than Demand Shortfalls
For AI infrastructure, demand presents no problem while construction does. Energy supply, permitting processes, and local political resistance have emerged as more realistic constraints than any demand collapse. At the grid level, transmission and permitting issues take precedence over generation capacity itself. A grid designed for approximately 100 basis points of annual load growth now faces growth rates near 300 basis points, rendering both planning and capital allocation inadequate. A recently completed 1,000-mile interstate high-voltage transmission line required 18 years for permitting approval alone.
Critical risk signals for data center investments include convenience termination clauses, leases lacking tariff or commodity protection, and non-investment-grade tenants. A typical construction cycle requires approximately 40,000 tons of copper and 100,000 tons of steel for two large buildings, with roughly three years needed from contract signing to stable operations. Notably, 98% of new data centers by megawatt capacity are single-tenant arrangements, meaning tenant credit quality and construction standards will determine long-term asset viability. Data centers have been compared to submarines, functioning well when operational but failing completely when shut down, with no intermediate state.
The report additionally noted that AI has dramatically enhanced cyberattack capabilities, transforming defense into an arms race. For highly regulated institutions such as banks, AI-related cybersecurity and fraud risks mandate significant defensive spending that generates no new revenue.
Geopolitical Risk Premiums Remain Underestimated with Elevated Oil Prices Potentially Extending into Early 2027
The Strait of Hormuz continues to serve as the world's critical energy chokepoint, historically handling approximately 20-23 million barrels per day, with existing alternative infrastructure far from sufficient to replace it. Even though the strait's direct importance to the United States has diminished, it remains a significant bottleneck for global crude oil, refined products, and LNG trade. Iran's strategic objective involves establishing credible deterrence against potential future US or Israeli attacks, with control over the Strait of Hormuz potentially providing such leverage. Asian oil-consuming nations appear willing to accept transit fees of approximately $1 per barrel, translating to potential annual revenues of $40-50 billion for Iran.
Under a permanent conflict scenario, JPMorgan's commodity strategy team estimates Brent crude averaging only $87 per barrel in 2027, compared to $64 per barrel in their base case assuming global peace by early 2027. Even with crude stabilizing near $90, persistent refined product tightness and rising geopolitical risks will sustain energy inflation and commodity market volatility. One speaker projected geopolitical risk premiums persisting through at least 2027, reasoning that regardless of whether the Iranian regime emerges weakened from conflict, generating further instability, or survives while continuing support for Hezbollah, Hamas, and Houthi forces, the underlying causes of regional tensions will persist.
Affordability Politics Will Shape Fiscal and Regulatory Trajectories
Polling indicates only 25% of Americans feel satisfied with the country's direction, below the historical average of 33%. According to Gallup surveys, high living costs represent the most important household financial issue for 31% of respondents, a proportion particularly pronounced among younger demographics.
The conference speakers concluded that a Democratic House flip appeared nearly certain with approximately 90% probability, while the Senate remained likely to stay under Republican control. Regardless of midterm election outcomes, the affordability theme will continue shaping fiscal and regulatory paths, including the resurgence of wealth tax discussions and universal basic income policy considerations. JPMorgan believes markets may be overly optimistic about the post-election policy environment. Potential lame-duck period risks include Trump potentially utilizing executive orders to intensify reciprocal tariff implementations, potentially lifting global effective tariff rates from 5%-6% back to the 17%-18% range, along with a third reconciliation budget package of at least $300-500 billion containing approximately $15 billion in agricultural assistance and over $150 billion in additional defense spending, which would further pressure US Treasuries and prompt rating agencies to reassess fiscal outlooks.
Stanford economists estimate that under the latest oil price scenario, average households may need to spend approximately $857 in additional gasoline costs for the remainder of the year, nearly offsetting the personal tax benefits provided by the Big Beautiful Bill.
