Equity Markets: Sectoral Bifurcation Deepens

US equity indices masked severe internal rotation throughout the week. The S&P 500 traded in a narrow range between 6,817 and 6,870, declining 0.6 per cent by Friday to 6,831, while the Nasdaq oscillated between losses and gains, closing Thursday down 0.3 per cent [9][10]. The surface stability concealed a historically sharp sectoral bifurcation: defence equities surged, with Lockheed Martin reaching an all-time high near $692 (up 40 per cent year to date), Northrop Grumman advancing over 6 per cent, and Korean defence names rallying 20 per cent, while consumer discretionary declined 21.4 per cent year to date against a 15.9 per cent gain in consumer staples [11][12]. The Magnificent Seven basket fell 7.0 per cent year to date while the equal-weight S&P 500 returned 7.0 per cent, a 14-percentage-point divergence that analysts compared to the March 2000 rotation [13]. Alphabet's capex guidance of $175 billion to $185 billion, well above the $119.5 billion consensus, amplified doubts about AI return profiles rather than reassuring investors of growth commitment [10]. The Variant Perception tactical correction signal activated for only the third time in seven years, flagging credit and volatility deterioration not yet reflected in headline indices and warning of a potential test of the 200-day moving average at 6,579, some 290 points below Friday's close [14]. European and Asian markets told a starker story. The STOXX 600 fell cumulatively over 2.5 per cent across the week, the DAX declined between 2.6 and 4.0 per cent, and the FTSE 100 dropped 2.75 per cent, reflecting the continent's structural energy vulnerability with EU gas storage at just 31 per cent of capacity [15][16]. South Korea's KOSPI collapsed 12.06 per cent in its worst session on record, driven by Samsung and SK Hynix declines of 10 to 12 per cent each, compounding semiconductor profit-taking with South Korea's net oil import exposure of 2.7 per cent of GDP, the highest among major Asian economies [17]. The contradiction between US resilience and European or Asian weakness reveals a divergence in perceived vulnerability: US markets price a contained conflict with defence spending upside, while European markets price energy cost pass-through into industrial margin compression and consumer demand destruction.

Fixed Income: Bonds Refuse the Safe Haven Script

The most structurally significant development in fixed income was the failure of government bonds to rally during geopolitical stress. The US 10-year Treasury yield rose from 3.95 per cent at the start of the week to 4.12 per cent by Thursday, a sustained four-session climb including a 10-basis-point single-day move on Monday, the largest since June 2025 [18][19]. The 30-year yield reached 4.75 per cent while the 2-year climbed to 3.56 per cent, producing a bear steepening pattern in which longer-duration yields rose faster than shorter maturities [18]. The mechanism is direct: markets are treating this as an inflation shock rather than a growth shock, and sustained energy price elevation adds an estimated 0.2 to 0.5 percentage points to headline inflation, constraining Fed cutting capacity [20]. Market pricing for the first 2026 rate cut shifted from July to September, with expectations of a third cut in 2026 nearly evaporating [20]. The 10-year German Bund yield climbed 10 basis points to 2.85 per cent, its steepest weekly front-end move in a year, while UK two-year gilts rose 28 basis points to 3.80 per cent, approaching the largest two-day increase since August 2024 [21]. Credit markets exhibited tiered deterioration beneath surface stability. Investment-grade option-adjusted spreads actually tightened marginally to 82 basis points by midweek, but high-yield spreads widened to 3.08 per cent from 2.98 per cent, CCC-rated spreads jumped 30 basis points to 9.57 per cent, and single-B spreads widened to 3.36 per cent from 3.23 per cent [22][23][24]. This differentiation within the risk spectrum signals that institutional investors are pruning lower-quality credit exposure vulnerable to energy-cost margin compression while maintaining confidence in higher-rated corporates. The MOVE index surged to 73.38, well above the 40 to 50 range of policy-certainty periods, confirming that Treasury options markets are pricing elevated yield-curve dislocation risk [25]. ECB Chief Economist Philip Lane's explicit statement that a prolonged conflict could produce a substantial spike in euro-zone inflation while reducing growth formalised the stagflationary framing that bond markets had already begun pricing [7].

Capital Flows: Defensive Rotation Beneath Record Passive Inflows

February 2026 saw record ETF inflows of $173 billion, projecting toward $2 trillion for the full year, yet the composition revealed defensive rebalancing beneath the headline: long-term US government bond ETFs experienced outflows of $162 million and below-investment-grade credit lost $200 million, confirming that duration and credit risk were being actively de-risked even as passive equity allocations continued mechanically [26]. European-listed equity ETFs gathered EUR 8.26 billion in net inflows in Week 8, the largest weekly allocation on record, driven by defensive rotation into dividend and value strategies rather than risk appetite [27]. Sovereign wealth funds deployed $132 billion into the United States during 2025, roughly half their total annual investments, but this allocation pattern faces stress: Saudi Arabia's Public Investment Fund, which deployed $36.2 billion in 2025, confronts windfall oil revenues coinciding with direct military threats to Gulf energy infrastructure, creating incentives for tactical risk reduction precisely when liquidity is most constrained [28]. Abu Dhabi's announcement of L'IMAD, a new sovereign wealth fund absorbing ADQ's portfolio, signals a significant restructuring of Gulf sovereign architecture during the conflict [29]. Chinese insurance companies are expected to invest approximately 1 trillion yuan ($145 billion) in public equities in 2026, with stock and fund holdings jumping 38.9 per cent to 5.7 trillion yuan by end 2025, representing 15.4 per cent of total assets, the highest allocation since mid-2022, creating a policy-driven structural bid for Chinese equities even as the Shanghai Composite fell 0.98 per cent on 4 March [30]. The US Dollar Index moved erratically, surging to 99.39 on Monday in its sharpest rally since May 2025, before retreating to 99.06 by midweek, a pattern that signals foreign central banks pricing the geopolitical shock as forcing the Fed toward cuts rather than hikes, weakening the dollar on a trade-weighted basis despite safe-haven demand for Treasuries [31][32]. The yen weakened to 157.75 against the dollar rather than strengthening as traditional safe-haven dynamics would predict, a counterintuitive move driven by Japan's acute energy import dependence and residual short-yen positioning [33].

Commodities: Energy Shock Approaches Non-Linear Threshold

Brent crude surged from approximately $72 pre-conflict to $91.58 by Friday 6 March, a 27 per cent increase, with WTI closing above $80 for the first time since summer 2024 [1][34]. The proximate drivers evolved through the week: initial Strait of Hormuz closure was compounded by QatarEnergy's indefinite LNG halt, which removed roughly one fifth of global supply, then partially offset by Saudi Arabia's rerouting of approximately 2.5 million barrels per day through Red Sea terminals at Yanbu via the East-West pipeline [2][3][35]. However, Yanbu's loading capacity is capped at 4.3 to 4.5 million barrels per day against Saudi production exceeding 10 million, and the Habshan-Fujairah pipeline from Abu Dhabi has already been targeted by drones [35]. Iraq cut approximately 50 per cent of crude production due to storage constraints, risking the loss of nearly 3 million barrels per day of exports if Hormuz transit does not resume, while OPEC+ approved only 206,000 barrels per day of additional output for April, a volume profoundly inadequate relative to the supply gap [36][37]. Goldman Sachs circulated a scenario of $100 to $120 oil; JPMorgan warned of $120 to $130 in a prolonged closure [38][39]. Dutch TTF natural gas stood at EUR 50.85 per megawatt-hour, up 64 per cent from pre-conflict levels [40]. A critical gap emerged between spot prices and analyst consensus forecasts: the EIA forecasts Brent averaging $58 for 2026, Goldman Sachs projects $56 pre-conflict, and a Reuters poll of 34 analysts raised 2026 Brent to only $63.85, implying either that the market has materially overshot or that analyst models have not yet incorporated the full duration risk of Hormuz closure [41]. Gold exhibited unusual behaviour, initially falling 4 to 6 per cent to approximately $5,050 on Monday as dollar strength and rising real rates reduced the appeal of zero-yield assets, before rebounding past $5,200 by midweek as central bank accumulation (emerging market purchases averaging approximately 60 tonnes per month) and geopolitical risk reasserted the safe-haven bid [42][43]. China maintained a 15-month consecutive purchasing streak, lifting gold reserves to nearly 10 per cent of total reserves [43]. Copper's decline to $5.75 to $5.79 per pound, down 2.9 to 3.5 per cent over the past month, served as the clearest cross-asset signal that markets are beginning to price stagflation expectations rather than pure inflation or pure growth weakness [44]. Ultra-low-sulphur diesel futures surged over 11 per cent to $3.22 per gallon, with immediate pass-through implications for transport costs and consumer price indices [45].

Policy & Macro

Monetary Policy: The Stagflation Trap Materialises

The week's most consequential policy development was the rapid closure of central bank easing capacity. Morgan Stanley formally reversed its 2026 ECB guidance, moving from expectations of two rate cuts to none, on the basis that elevated energy prices will push euro-area inflation above target through the second half of the year [8]. Market pricing assigned a 40 per cent probability of an ECB rate hike by year end, a dramatic swing from the cut consensus of just one week prior [21]. The ECB had held at 2.0 per cent on 5 February as eurozone inflation rose to 1.9 per cent in February from 1.7 per cent in January, with core inflation ticking up to 2.4 per cent and services inflation accelerating to 3.4 per cent, a trajectory the energy shock now threatens to accelerate sharply [46][47]. The Federal Reserve's January hold at 3.50 to 3.75 per cent was already fractured: two FOMC members (Miran and Waller) voted for an immediate cut while several others wanted to preserve the option of rate increases, language rarely used outside recession preparedness [48][49]. The energy shock has widened this split by creating an inflation-growth trade-off that supports both sides simultaneously. Market pricing for the first cut shifted from July to September, with a third 2026 cut nearly priced out [20]. The Bank of England's probability of a March 19 cut collapsed from 75 per cent pre-conflict to 20 per cent, despite the February decision splitting 5 to 4 to hold at 3.75 per cent and UK unemployment reaching 5.2 per cent, the highest in nearly five years [50]. ING analysts estimated that if natural gas remains at or above EUR 50 per megawatt-hour into Q2 and oil approaches $85 to $90, headline UK CPI could test 3.5 per cent [50]. The RBA provided a counter-narrative by raising rates 25 basis points to 3.85 per cent on 3 March, a unanimous decision responding to demand growth that had 'strengthened substantially more than expected,' illustrating that the global policy cycle is not unidirectional and that supply-side shocks elicit divergent responses depending on domestic conditions [51]. The Bank of Japan faces intensifying pressure at 0.75 per cent, with board member Masu stating further hikes are 'necessary to complete monetary policy normalisation,' but the energy shock may paradoxically ease pressure to hike aggressively since it constitutes a supply shock rather than a signal of persistent domestic demand [52]. The Bank of Canada's framework review, explicitly identifying supply-driven trade-offs as the defining challenge of the current era, may preview the analytical reorientation other central banks will adopt: a shift from demand management to supply-side accommodation that would fundamentally alter the transmission mechanism of monetary policy [53]. The March 17 to 19 triple central bank meeting cycle, encompassing the ECB, FOMC, and Bank of England, is now the critical inflection point: markets are frontrunning a scenario in which each institution acknowledges energy shock persistence and formally delays easing.

Growth and Labour: Softening Beneath the Surface

The US labour market delivered the week's most significant macroeconomic data point on Friday: total nonfarm payrolls declined by 92,000 in February, a sharp deterioration from January's 130,000 gain, with the unemployment rate holding at 4.4 per cent [4]. The ADP private payrolls report on Wednesday had previewed the weakness at 63,000, accompanied by substantial backward revisions including October 2025 revised downward by 159,000, indicating the underlying trend is weaker than monthly headlines suggested [54]. The labour market now presents two competing readings that cannot be reconciled from current data: the headline unemployment rate masks rising long-term unemployment (1.8 million, up 386,000 year on year), flat labour force participation at 62.5 per cent, and a ratio of job openings to unemployed persons that fell below 1.0 for the first time since mid-2017, confirming a decisive shift toward employer leverage [55][56]. Manufacturing employment has declined every month since March 2024, while the majority of recent job creation is concentrated in education and health services, a narrow set of low-productivity sectors [54]. Monday's 'watch' item on whether the employment report would confirm or disconfirm the softening narrative was decisively resolved: the negative payrolls print confirms accelerating deterioration and strengthens the case for a June Fed cut, but the energy shock's inflation impulse creates a direct policy contradiction. The eurozone presented a contrasting picture: the flash manufacturing PMI reached 50.8 in February, a 44-month high, with Germany returning to growth for the first time in approximately 3.5 years, yet factory employment continued to contract for a 17th consecutive month, reflecting firms extracting productivity gains rather than expanding headcount amid elevated labour costs [57]. Input cost inflation accelerated to a 12-month high in the PMI survey, driven partly by German minimum wage increases, introducing a feedback loop where fiscal stimulus feeds into wage costs that complicate the ECB's inflation management [57]. The UK labour market deteriorated to 5.2 per cent unemployment, the highest excluding pandemic since a decade, with the OBR revising 2026 GDP growth down to 0.7 per cent from 1.1 per cent, citing cyclical weakness and the largest fall in net trade since 2014 [58][59]. China's formal setting of the 2026 GDP growth target at 4.5 to 5 per cent, the lowest since 1991, paired with an unchanged 4 per cent fiscal deficit and explicit adoption of 'appropriately accommodative' monetary policy language last used during the 2008 financial crisis, confirmed structural growth deceleration and de facto licensed PBOC easing [5][6]. Monday's watch item on whether China would cut the target below 5 per cent was confirmed: Beijing chose the lower range, signalling prioritisation of financial stability over stimulus-dependent expansion.

Fiscal Dynamics: Constrained Space Across Jurisdictions

Fiscal capacity across major economies proved insufficient to offset the combined energy and growth shocks. US national debt is approaching $39 trillion with CBO projections of a $1.9 trillion deficit in fiscal 2026, or 5.8 per cent of GDP, with debt held by the public reaching 101 per cent of GDP and surpassing the 1946 record of 106 per cent by 2028 on current trajectory [60]. Treasury Secretary Bessent's announcement of a 15 per cent global tariff under Section 122 of the Trade Act, replacing the framework invalidated by the Supreme Court's 6 to 3 ruling, represents both a fiscal and legal inflection point: the 150-day statutory limit creates a deadline that will force either congressional action or tariff expiry, neither of which is priced into current revenue assumptions [61][62]. The tariff regime's interaction with the energy shock is compounding: Beige Book documentation of widespread corporate expectations of Q1 price increases creates goods inflation stickiness that persists independently of energy costs [63]. China's decision to hold the fiscal deficit at 4 per cent of GDP despite lowering the growth target signals fiscal commitment to offset external demand weakness rather than pursuing stimulus-dependent expansion, but creates a coordination problem: Chinese fiscal support may sustain domestic demand for energy imports precisely when global supply is disrupted, potentially supporting higher prices for longer [5]. Germany's planned budget deficit of 4.75 per cent of GDP in 2026, its largest since 1975, provides an offsetting European fiscal impulse, while France adopted a compromise budget targeting 5 per cent, improved from 5.4 per cent in 2025 but still above the EU's 3 per cent reference value [64][65]. The UK's fiscal position is constrained by the OBR's downward growth revision and the need to protect £15 billion in headroom, while mounting defence spending pressures from the conflict add to outlays [59]. The structural pattern is clear: fiscal constraints across developed economies mean central banks bear disproportionate responsibility for demand management, yet the energy shock is simultaneously reducing their capacity to ease, creating a policy trap where neither fiscal nor monetary authorities can respond effectively to a growth slowdown without accepting higher inflation.

Technology & Systems

AI Infrastructure: Power Displaces Silicon as the Binding Constraint

The week crystallised a structural shift in which energy infrastructure overtook semiconductor supply as the primary gating factor for AI compute expansion. Seven major technology firms signed President Trump's ratepayer protection pledge on 5 March, committing to fully finance their own power generation and grid upgrades for AI data centres, a binding financial obligation that shifts an estimated $5 billion to $10 billion per hyperscaler in infrastructure costs onto corporate balance sheets over 2026 to 2028 [66][67]. The political driver is residential electricity prices rising from 15.9 cents per kilowatt-hour in January 2025 to 17.2 cents by December 2025, with data centre electricity demand projected to rise from 4 to 6 per cent of total US supply to 12 per cent by 2028 [67]. The five largest hyperscalers have committed $660 billion to $690 billion in capital expenditure for 2026, consuming approximately 90 per cent of aggregate operating cash flow, with Amazon leading at $200 billion, Alphabet at $175 billion to $185 billion, Microsoft at $120 billion, Meta at $115 billion to $135 billion, and Oracle at $50 billion [68][69]. Microsoft disclosed an $80 billion backlog of unfulfilled Azure orders attributable to power constraints rather than demand softness, with idle GPU inventory confirming that the bottleneck has shifted from chip availability to energy access [69]. The International Energy Agency projects data centre electricity consumption roughly doubling from 415 terawatt-hours in 2024 to 945 terawatt-hours by 2030, with Morgan Stanley forecasting a 49-gigawatt shortfall against 74-gigawatt US demand by 2028 [70]. Hyperscalers are responding with backward vertical integration: Meta signed nuclear agreements for up to 6.6 gigawatts with TerraPower, Oklo, and Vistra, while Microsoft secured a 10.5-gigawatt framework with Brookfield Renewable Partners valued at $10 billion to $11.5 billion [71][72]. The Iran conflict adds a second-order dimension: sustained energy price elevation increases the cost basis for grid-connected data centres, accelerates the shift toward behind-the-meter generation, and simultaneously raises the economic case for nuclear and renewable alternatives. The model release cadence simultaneously shifted toward inference efficiency: OpenAI's GPT-5.3 Instant achieves comparable reasoning at half the cost and double the speed of GPT-5.2, Google's Gemini 3.1 Flash-Lite prices developer workloads at $0.25 per million input tokens, and Alibaba's Qwen 3.5-9B outperforms GPT-4 equivalents on coding tasks while running on standard laptops [73][74]. This convergence on cost per token rather than raw parameter scaling signals that the frontier has shifted from training scale to inference economics, a development with material implications for the return assumptions embedded in current capex levels. Enterprise AI adoption has reached 87 per cent, but only 20 per cent of organisations report revenue growth from AI versus 66 per cent reporting efficiency gains, a gap that undermines the top-line growth narrative supporting hyperscaler investment [75].

Semiconductor Supply Chains: Geopolitical Allocation Replaces Market Demand

Nvidia's announcement on 5 March that it has halted H200 chip production for the Chinese market and is redirecting scarce TSMC CoWoS advanced packaging capacity toward its next-generation Vera Rubin architecture confirmed a new operating principle: advanced semiconductor production capacity at the most constrained nodes is now allocated based on geopolitical alignment rather than market demand [76][77]. The decision followed mutual regulatory escalation: Washington pushed for tighter deployment restrictions while Beijing's customs authority blocked imports and instructed domestic firms to prioritise Huawei and Cambricon alternatives. Nvidia has generated zero revenue from H200 chips in China [76]. Draft US regulations requiring government permits for chip exports based on GPU cluster size, with deployments exceeding 200,000 GB300 units requiring security clearance, represent the first binding regulatory constraint on AI infrastructure spending since the rally began in 2023 [10][78]. TSMC controls 71 per cent of the global foundry market with 2025 revenue of $122 billion and guided 2026 capex at $52 billion to $56 billion, a record, with 70 to 80 per cent allocated to leading-edge processes [79][80]. CEO Wei acknowledged feeling 'very nervous' about the capex commitment, revealing tension between multi-year customer pull and stranded-asset risk [79]. The most acute physical constraint has shifted from wafer production to advanced packaging: CoWoS capacity remains sold out through mid-2026, while SK Hynix and Micron report their entire 2026 high-bandwidth memory supply is fully booked, with Samsung announcing price increases of high teens to low twenties per cent on 2026 contracts [81]. TrendForce projects average DRAM prices rising between 50 and 55 per cent this quarter, characterised as 'unprecedented,' as memory firms exit consumer markets to focus on high-margin AI products [82]. Samsung's Taylor, Texas advanced semiconductor facility delay is particularly significant because it was intended to diversify advanced chip production away from geopolitically exposed Asian facilities, and its postponement re-concentrates supply-chain risk precisely when geopolitical tensions argue for dispersion [17]. Nvidia's allocation of 25 per cent of 2028 Feynman GPU production to Intel foundries for non-core I/O dies signals deliberate diversification away from TSMC concentration, not because TSMC is losing technical leadership but because the industry is consciously reducing geopolitical and supply-chain concentration risk [83]. The industry faces a structural contradiction: record investment justified by binding customer commitments from a narrow set of hyperscalers, yet management anxiety about sustainability echoes patterns from the early 2000s telecommunications equipment bubble.

Regulatory Fragmentation and Technology Bifurcation

Export control fragmentation accelerated through the week, creating increasingly distinct technology stacks for the US, China, and Europe. China's domestic semiconductor equipment share rose from 25 per cent in 2024 to 35 per cent in 2025, surpassing the 30 per cent target, with Beijing reportedly requiring at least 50 per cent domestic equipment in new fab projects [84][85]. AMEC's 5nm etching tool has entered validation on TSMC's production lines, but engineers report domestic tools still require extended debugging and may increase production costs by 5 to 8 per cent [85]. Alibaba's C930 processor uses RISC-V architecture to circumvent dependence on ARM or Intel instruction sets, while the 15th Five-Year Plan shifts responsibility for AI and semiconductor development from research to commercial deployment [86][87]. The Congressional AI OVERWATCH Act would prohibit Blackwell chip sales to foreign entities of concern for two years, signalling Congress's intent to constrain executive flexibility regardless of administration preference [88]. The EU AI Act enters full enforcement on 2 August 2026 with fines of up to EUR 35 million or 7 per cent of worldwide turnover, though France and Germany have jointly requested a 12-month postponement of high-risk system rules, signalling implementation challenges that expose the tension between regulatory coherence and competitive positioning against US and Chinese AI development [89]. The US Commerce Department faces a 11 March deadline to evaluate state AI laws for potential federal preemption, which will signal the administration's willingness to consolidate AI governance authority [90]. Japan's record ¥1.23 trillion semiconductor and AI budget for fiscal 2026, nearly quadrupling prior appropriations, with ¥150 billion earmarked for Rapidus at the 2-nanometre node, signals institutional commitment to long-term technology sovereignty [91]. The structural pattern is technology bifurcation accelerating under geopolitical pressure, with energy disruption adding a physical constraint dimension that reinforces the incentive for regional self-sufficiency in both chip manufacturing and power generation.

Week Ahead

Key Events

The March 11 US Commerce Department deadline on state AI law evaluation will signal whether the federal government intends to consolidate or fragment AI governance. Preemption of state laws would confirm centralisation of regulatory authority and reduce compliance costs for technology firms; deference to state frameworks would create a patchwork that raises compliance expenditure in the second half of 2026 [90]. The March 17 to 19 triple central bank meeting cycle is the week's defining event. The ECB meets on 17 March with February's inflation surprise and energy-driven cost pass-through creating pressure to revise its easing assessment; a hawkish hold with upward inflation forecast revision would confirm that the European rate-cutting cycle is paused indefinitely, validating Morgan Stanley's reversal [8][46]. The FOMC meets on 18 March with the February payrolls contraction of 92,000 creating tension against energy-driven inflation persistence; any forward guidance change acknowledging the stagflationary trade-off would mark a structural shift in communication. The Bank of England meets on 19 March with cut probability at 20 per cent; a dovish surprise given the 5 to 4 prior split would signal that at least one major central bank is willing to look through the energy shock, while a unanimous hold would confirm the stagflationary repricing [50]. Strait of Hormuz transit volumes remain the highest-sensitivity variable across all asset classes. Restoration of commercial shipping would confirm the contained-shock thesis and likely trigger immediate crude price declines of 10 to 15 per cent; continued closure beyond the two-week strategic reserve buffer (approaching exhaustion for some Asian importers) would push oil toward the $100 to $120 range that Goldman Sachs has modelled, with identifiable consequences through high-yield spreads widening above 350 basis points and renewed 2s10s compression below 40 basis points [38][39]. The House vote on the Khanna-Massie war powers resolution, if it has not concluded by Monday, will determine whether the late May authorisation deadline becomes a binding political constraint on the campaign's duration; passage would not stop operations given a presidential veto but would establish legal grounds for future challenges and introduce a temporal bound on the energy supply disruption [92].

Structural Questions

Has the global monetary policy cycle reversed? The RBA's surprise hike, Morgan Stanley's withdrawal of all ECB cuts, and the evaporation of BoE cut probability within a single week suggest that the easing consensus that prevailed from late 2024 may have been structurally broken by the energy shock rather than merely delayed, but this reading depends on whether oil prices sustain above $85 or revert toward the $60 to $65 consensus range. Can hyperscaler capex commitments of $660 billion to $690 billion survive a simultaneous repricing of energy costs, higher discount rates from Treasury yield steepening, and the shift of $5 billion to $10 billion per firm in power infrastructure onto corporate balance sheets, or will the enterprise AI revenue gap (only 20 per cent of organisations reporting revenue growth) force a capex reduction cycle that cascades through the semiconductor value chain? Is the geopolitical allocation of advanced semiconductor capacity, now confirmed by Nvidia's H200 halt for China and Intel's role as a diversification foundry, a permanent structural feature or a cyclical response to conflict conditions, and what does the answer imply for the long-term cost structure of AI compute in non-allied markets?
