Bear flattening of the Treasury curve reprices Fed path as day 26 escalation erases Monday's relief trade — PatternSignals Daily Brief

The dominant signal overnight is not the resumption of hostilities between Iran and the US-Israel alliance, which the reader already knows, but its transmission mechanism through the Treasury curve: the 2-year yield's 9 basis point surge to 3.93% on 24 March, outpacing the 10-year's 5 basis point move to 4.39%, produces a bear flattening that embeds a 44% probability of a Fed rate hike by year end, up from single digits two weeks ago [7][10]. This curve signal arrived simultaneously with the strongest US manufacturing PMI since October 2025, at 52.4, where new orders strength collided with supplier delivery times at their longest since October 2022, confirming that the energy shock is hitting an economy with constrained supply rather than slack demand [13]. The structural consequence is that central banks' stated preference to look through a temporary supply shock is being tested by a market that now prices persistence, and the five day Trump ultimatum window, which expires around 28 March, coincides with the February PCE release that will either validate or undermine the transitory framing.

Markets & Capital

Equity Markets

The S&P 500 closed down 0.37% at 6,556 on 24 March, erasing roughly three quarters of Monday's 1.15% relief rally, while the Nasdaq 100 fell 0.77% as growth stocks bore the heaviest selling pressure [1][36]. The Russell 2000's modest 0.59% gain against the broader decline suggests the defensive rotation into domestically oriented small caps that began in early March remains intact, even as the Magnificent Seven collectively reversed Monday's gains, with Microsoft now down 21% year to date and testing critical support levels [4][42][49]. The sectoral pattern is diagnostic: energy held ground while technology gave back its de-escalation premium, consistent with a market that is pricing inflation persistence rather than demand destruction. The S&P 500 remains below its 200 day moving average but above intermediate support near 6,500, a technical no man's land that favours neither directional conviction nor forced liquidation [43]. State Street institutional flow data shows sovereign wealth funds entered 2026 with elevated equity exposure and reduced dollar holdings, positioning them as net sellers into strength rather than buyers of dips, which reinforces the probability that any further decline meets passive index buying but active institutional distribution [27].

Fixed Income

The overnight Treasury move is the most structurally consequential development of the past 24 hours. The 10 year yield closed at 4.39%, up 5 basis points and now 40 basis points above pre conflict levels, while the 2 year yield's sharper 8 basis point rise to 3.96% compressed the 10 year minus 2 year spread to 49 basis points from 51 the prior session [8][9][50]. This bear flattening pattern, where the front end reprices faster than the long end, is the market's mechanism for signalling that the Federal Reserve's capacity to cut rates is being structurally impaired by energy driven inflation expectations. The five year, five year forward inflation expectation rate stood at 2.11% on 24 March, barely changed from 2.14% a week earlier, revealing a stickiness that undermines the Fed's transitory narrative [35]. Goldman Sachs estimates the crude oil risk premium at approximately $14 per barrel, corresponding to a full one month Strait of Hormuz closure scenario; if that premium persists, 10 year yields face a technical test at 4.50% to 4.60%, a level consistent with sustained supply disruption pricing [34]. Investment grade spreads held flat at 88 basis points and high yield actually compressed 8 basis points to 3.19% on 23 March, indicating that credit markets have not yet migrated from inflation pricing to distress pricing, but this calm is fragile if oil sustains above $100 [24][25].

Capital Flows

The US dollar index rose 0.42% on 24 March, extending a 3% appreciation trend since the conflict began, driven not by equity inflows but by geographic arbitrage: the US as a net petroleum exporter benefits structurally from energy disruption that penalises import dependent European and Asian economies [19][39]. This dollar strength occurring alongside equity weakness inverts the normal risk off pattern and reveals that capital is rotating toward dollar denominated fixed income as an inflation hedge rather than toward non yielding safe havens. Gold's flat to slightly negative performance at $4,427, well below its $4,500 conflict peak, confirms this reading: institutional capital is choosing yield bearing safety over commodity safety, a hallmark of inflation hedging rather than recession hedging [18][39]. February ETF flow data showed $186.6 billion in net inflows to US listed ETFs, with $81.7 billion flowing to passive equity vehicles versus $25.5 billion to active, meaning the wall of worry is being climbed via index exposure rather than conviction bets, leaving positioning vulnerable to passive rebalancing if support levels break [26].

Commodities & FX

WTI crude rose 2.6% to $90.41 and Brent returned to approximately $102.91 on 24 March, fully reversing the prior session's 10% collapse triggered by Trump's de-escalation statement [1][33]. The reversal was driven by confirmed Iranian strikes on Israeli cities including Tel Aviv, Eilat, and Dimona, and Israeli retaliatory strikes on targets in and around Tehran, which rendered the Monday negotiation narrative operationally obsolete within 12 hours [1][33]. The forward curve structure is the critical signal: calendar spreads remain elevated with early 2027 forwards anchored above $80, roughly $7 to $8 above pre conflict levels, embedding expectations of durable rather than transient supply risk [36]. Goldman Sachs' modelling of a full one month Strait of Hormuz closure projects Dutch TTF natural gas prices surging to 74 EUR/MWh from current levels near 31 to 32 EUR/MWh, a scenario that would devastate European industrial competitiveness; the absence of current LNG price dislocation indicates markets still assign low probability to this outcome, but the gap between oil repricing and gas stability represents a potential dislocation if the conflict persists past day 30 [34]. EUR/USD weakness remained modest, consistent with incremental repositioning rather than panic outflows [20].

Policy & Macro

Monetary Policy

No central bank communicated in the past 24 hours, but the market has communicated on their behalf. Fed funds futures now embed a 26% probability of a rate hike by year end, a figure that was essentially zero before the conflict began on 28 February [17][48]. The Fed's March 18 dot plot showed a median expectation of a single 25 basis point cut for 2026, but the combination of oil above $90, manufacturing PMI at 52.4 with rising input prices, and five year inflation expectations sticky above 2.1% has shifted the distribution of outcomes: the market is now pricing scenarios in which even the single projected cut does not materialise [7][35]. The ECB faces a sharper version of this bind, having already raised its 2026 inflation forecast to 2.6% at the 19 March meeting with the bulk of the upside driven by energy; any fiscal intervention to cap consumer energy prices, as the IMF warned on 21 March, would suppress the demand destruction mechanism and extend inflation persistence [2][26]. The Bank of Japan retains the most flexibility, with CPI at 1.3% as of February and lower structural energy exposure, but even the BoJ's hold at its March meeting reflects caution about second round effects [22][23]. The structural picture is that the central bank consensus to look through a temporary supply shock is entering a credibility test: if the PCE print on 28 March shows core above 0.35% month on month, the transitory framing becomes politically untenable.

Growth & Labour

The March flash US manufacturing PMI at 52.4 exceeded the 51.3 consensus and rose from 51.6 in February, with new orders posting their strongest increase since October 2025 and export demand stabilising after eight consecutive months of contraction [13]. However, the internals contain a material contradiction: employment growth slowed to an eight month low while supplier delivery times lengthened to levels not seen since October 2022, the steepest supply side tightening in over three years [13]. Firms reported precautionary stockpiling driven by fears of prolonged Middle East disruption and elevated commodity prices, behaviour that inflates near term production readings but reflects supply chain anxiety rather than organic demand. Business confidence reached a 13 month high, yet this optimism sits alongside input and output price surges that, if sustained, will compress margins and force pass through to consumers. The net reading is an economy generating its own demand impulses while simultaneously facing supply constraints, a stagflationary mixing bowl that is fundamentally different from an energy shock hitting a slack economy. The Fed's March 18 characterisation that job gains have remained low is not contradicted by this data but neither is it reinforced; manufacturing employment weakness may be masking services resilience that will only become visible in the April payrolls report.

Fiscal Dynamics

The IMF's 21 to 22 March guidance that central banks should assign very high option value to waiting was accompanied by a pointed warning that energy subsidies, while politically attractive, suppress price signals and extend inflation persistence by reducing the demand side response to higher costs [26]. This creates a policy trilemma for European governments: Germany's defence and infrastructure fiscal expansion, already committed, arrives into an environment where energy costs are simultaneously rising, meaning the fiscal impulse adds demand into a supply constrained economy [50]. China's January credit data revealed that new yuan loans of 4.71 trillion yuan fell below the 5 trillion consensus, with government bond issuance substituting for stagnant private credit demand, confirming that Chinese growth remains fiscally dependent rather than organically driven [42]. The PBOC has signalled room for RRR cuts and rate adjustments but has not deployed them, and the yuan's 1% appreciation against the dollar in the preceding month gives technical space for easing without immediate capital flow consequences [42]. For the global picture, the absence of coordinated fiscal response to the energy shock contrasts with the 2022 playbook when European governments deployed large scale energy subsidies within weeks; the delay likely reflects lessons learned about inflation persistence, but it also means household and corporate balance sheets are absorbing the full price signal, which accelerates the demand destruction channel the IMF implicitly endorses.

Technology & Systems

AI Infrastructure

No new AI infrastructure announcements emerged in the past 24 hours, but the energy cost channel is becoming the binding constraint that connects the geopolitical crisis to technology capital expenditure timelines. Hyperscaler data centre buildouts across the US and Europe are structured around power purchase agreements priced at materially lower electricity costs than current spot levels; if European TTF gas prices were to approach the 74 EUR/MWh level that Goldman Sachs models for a one month Strait of Hormuz closure, the economics of European AI infrastructure expansion would face immediate repricing [34]. The absence of any hyperscaler commentary adjusting capex guidance since the conflict began on 28 February suggests either that procurement teams view the disruption as temporary or that long term PPAs insulate near term operations. Samsung's 110 trillion won capex commitment for 2026, reported on 22 March, anchors the equipment order pipeline regardless of energy costs, but foundry utilisation rates and the timeline for advanced node ramp depend on sustained power availability at contracted rates. The bifurcation between Asian foundry expansion, which benefits from lower energy import dependence in South Korea and Taiwan relative to Europe, and Western data centre builds, which face both permitting and energy cost headwinds, is widening as the conflict persists.

Semiconductor Supply Chains

NVIDIA's H200 production restart for China, reported earlier in the week, continues to operate as the key data point for tracking the enforcement bottleneck in export controls. The selective relaxation at prior generation nodes while Blackwell and Rubin remain restricted creates a bifurcated compute market: Chinese hyperscalers and cloud providers can procure training capable hardware one generation behind the frontier, which is sufficient for most commercial inference workloads but insufficient for frontier model training at the parameter scales now being pursued by US and allied labs. The commercial consequence is a widening training to inference capability gap that entrenches US advantage in frontier research while allowing China to build out deployment infrastructure. No new export control announcements or CFIUS actions were reported overnight. The supplier delivery time lengthening flagged in the US manufacturing PMI, reaching October 2022 levels, may partly reflect semiconductor component shortages feeding into industrial and automotive supply chains, though the PMI report does not disaggregate to that level of granularity [13]. Equipment makers supplying into Samsung's and TSMC's expansion programmes face the same logistics friction, and any sustained Strait of Hormuz disruption would compound shipping delays for semiconductor manufacturing equipment transiting through affected maritime corridors.

Systemic Technology Shifts

The enterprise AI competitive landscape remains in the configuration reported earlier this week, with Anthropic holding a 73% first purchase share among enterprise customers and no new competitive response from OpenAI or other vendors in the past 24 hours. DeepSeek V4's continued delay removes a potential disruptor from the near term landscape and reduces the probability of a price war catalyst before mid 2026. The more structurally significant technology signal is the intersection between energy markets and compute economics: the energy sector's over 40% year to date gain on the S&P 500, the strongest start since 1990, reflects a repricing of energy as a strategic asset class that now directly competes with technology for capital allocation within institutional portfolios [41]. Historical analysis shows that in the three prior instances where energy rallied more than 10% through mid February, it continued to rally at least an additional 15% for the remainder of the year, suggesting that the rotation from technology to energy may have further to run if the geopolitical premium persists [41]. This sector level substitution has implications for AI infrastructure funding: if equity markets continue to reward energy exposure at the expense of technology multiples, the cost of equity capital for hyperscaler capex programmes rises, creating a feedback loop where energy price shocks slow the very infrastructure buildout that would eventually reduce dependence on fossil fuel powered compute.
