Iran conflict reprices energy, safe havens and central bank trajectories — PatternSignals Daily Brief

Global Context

Global Context

The US-Israeli military strikes on Iran beginning 28 February have triggered a simultaneous repricing across energy, equity, fixed-income and currency markets, creating a feedback loop in which higher oil prices raise inflation expectations, constrain central bank easing capacity, and redirect capital flows toward dollar-denominated safe havens [1][2][3]. This energy shock intersects with an already fragile macro backdrop: manufacturing contraction in China, cooling labour markets in the US and UK, and a rotation out of mega-cap technology stocks that had been underway since January — compounding the stress on risk assets and widening the divergence in central bank policy trajectories [4][5][6].

Markets & Capital

Equity Markets

The S&P 500 fell 0.94 per cent to 6,300, now 2.3 per cent below its 27 January record and approaching its 2026 closing low [7]. The Nasdaq Composite eked out a 0.36 per cent gain, masking severe single-name deterioration in mega-cap technology — Microsoft is down 18.6 per cent year-to-date and the Magnificent Seven basket has declined 7.0 per cent, while the equal-weight S&P 500 has returned 7.0 per cent, a divergence analysts have compared to the March 2000 rotation [8]. European indices suffered more acutely: the STOXX 600 fell 2.6–3.3 per cent, the DAX declined 3.4–4.0 per cent, and the FTSE 100 dropped 2.75 per cent, driven by the continent's structural energy vulnerability — EU gas storage sits at just 31 per cent of capacity, below the 40 per cent level of a year ago [9][10]. South Korea's Kospi collapsed 7.2 per cent, its worst session since August 2024, as Samsung and SK Hynix each fell 10–12 per cent, compounding technology profit-taking with South Korea's net oil import exposure of 2.7 per cent of GDP, the highest among major Asian economies [2][11]. The sectoral bifurcation is sharp: energy and defence equities rallied (Northrop Grumman +6 per cent; Korean defence names +20 per cent), while consumer discretionary has declined 21.4 per cent year-to-date and consumer staples have gained 15.9 per cent, a classic risk-off rotation that the geopolitical shock has accelerated rather than initiated [8][12]. The feedback loop is clear — higher energy costs compress non-energy margins, reducing earnings expectations, which validates the rotation into defensives, which in turn deepens the selloff in growth and cyclical names.

Fixed Income

US 10-year Treasury yields rose 9–12 basis points to 4.06 per cent over the 72-hour window ending 3 March, reversing the prior week's rally, as energy-driven inflation expectations overwhelmed the safe-haven bid for duration [13][14]. The 2-year yield climbed to 3.48 per cent, compressing the 10y–2y spread from 0.61 to 0.55–0.58 per cent, reflecting the market's recognition that an energy shock creates an inflation-growth trade-off that limits Fed flexibility [13][14]. Market pricing for Fed rate cuts has shifted: the first expected reduction has moved from July to potentially September 2026, though two 25-basis-point cuts remain priced by year-end [15]. High-yield credit spreads have widened only modestly — the ICE BofA HY index to 3.03 per cent from 2.98 per cent — suggesting institutional credit investors view the shock as manageable, though single-B spreads have widened more (to 3.36 per cent from 3.23 per cent), signalling early differentiation within the risk spectrum [16]. The MOVE index has surged to 73.38, well above the 40–50 range of policy-certainty periods, indicating that Treasury options markets are pricing elevated yield-curve dislocation risk [17]. The 30-year fixed US mortgage rate held at 5.80 per cent despite the Treasury yield spike, as lenders widened servicing spreads to compensate for volatility — with only 21 per cent of outstanding mortgages above 6 per cent, the macro stimulus from refinancing remains limited [18].

Capital Flows

The US Dollar Index surged to 99.39, its sharpest single-day rally since May 2025, reasserting dollar safe-haven primacy despite the conflict directly involving US military operations [19][20]. EUR/USD fell to 1.1610, its lowest in several weeks, reflecting both dollar strength and the eurozone's specific energy import vulnerability [21]. The Japanese yen weakened to approximately 156–157 per dollar rather than appreciating as traditional safe-haven dynamics would predict, a counterintuitive move driven by Japan's acute energy import dependence (87 per cent fossil fuels), the BoJ–government policy tension, and residual short-yen positioning [22][23]. The Chinese yuan held relatively steady at 6.86 per dollar, supported by nine consecutive months of PBOC-guided appreciation and large strategic petroleum reserves that buffer short-term supply shocks [23][24]. 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 rather than risk appetite, consistent with the broader shift away from concentrated mega-cap technology exposure [25]. The feedback loop connecting dollar strength to emerging-market pressure remains active: a stronger dollar tightens financial conditions for dollar-denominated borrowers, reducing EM capital inflows and reinforcing the safe-haven bid for US assets.

Commodities and FX

Brent crude surged to $80–84 per barrel, up roughly 13 per cent from pre-strike levels of approximately $72, with intraday highs touching $85.12, the highest since July 2024 [26][27]. WTI reached $76.19, up 7.0 per cent on the session [26][28]. The supply disruption is material: approximately 20 per cent of global oil and a similar share of LNG transit the Strait of Hormuz, where some 150 ships have anchored as insurers cancelled coverage and ports including Dubai's Jebel Ali suspended operations [3][27]. Qatar's suspension of LNG production at Ras Laffan and Mesaieed — roughly one-fifth of global output — sent Dutch TTF natural gas futures up 25.5 per cent to EUR 54.35 per megawatt-hour, with intraday spikes of 45 per cent [10][29]. Goldman Sachs has targeted $110 Brent; JPMorgan has warned of $120–130 in a prolonged closure scenario [30]. Gold fell 4–6 per cent to approximately $5,345.64 per troy ounce — an unusual decline during geopolitical stress explained by dollar strength and rising real rate expectations reducing the relative appeal of zero-yield assets [31][32]. Silver collapsed nearly 12 per cent below $80 as leveraged positions were liquidated for dollar cash [31]. Ultra-low-sulphur diesel futures surged over 11 per cent to $3.22 per gallon, reaching two-year highs, with immediate pass-through implications for transport costs and consumer price indices [12][27]. The critical non-linearity: if Hormuz closure persists beyond the two-week buffer provided by Asian strategic reserves, analysts project oil could reach $100–130, adding 0.6–0.7 percentage points to global inflation and forcing material downward revisions to corporate earnings [2][27].

Policy & Macro

Monetary Policy

The Federal Reserve's January hold at 3.50–3.75 per cent was not unanimous: Stephen Miran and Christopher Waller dissented in favour of a rate cut, while several others wanted to signal that rate increases remained possible if inflation persisted above target [33][34]. Fed Chair Powell emphasised that a rate hike was 'nobody's base case,' yet the January PPI report — core at 3.6 per cent year-on-year, with a 0.8 per cent monthly gain versus 0.3 per cent expected — underscored the stickiness problem the energy shock now amplifies [35][36]. Goldman Sachs expects rates to reach approximately 3.0 per cent by year-end; Oxford Economics pencils in cuts in June and September — both forecasts contingent on oil prices not sustaining above $85 [37][38]. The ECB 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, above consensus — a trajectory the energy shock threatens to accelerate [39][40]. The Bank of Japan faces an acute tension: the policy rate at 0.75 per cent (highest since 1995) positions the BoJ for further normalisation, but Prime Minister Takaichi's reflationist government has been placing doves on the board and signalling opposition to hikes, creating a credibility risk that yen weakness reflects [41][42]. The RBA surprised markets by raising rates 25 basis points to 3.85 per cent on 3 February, a unanimous decision responding to demand growth that had 'strengthened substantially more than expected,' breaking the global easing consensus and illustrating that the policy cycle is not unidirectional [43]. The feedback loop across central banks is straightforward: energy-driven inflation compresses the space for easing, which tightens financial conditions, which slows growth, which eventually suppresses demand and reduces inflationary pressure — but the lag between the inflation impulse and the growth response creates a window of acute policy discomfort.

Growth and Labour

US nonfarm payrolls rose only 130,000 in January, with unemployment at 4.3 per cent, and long-term unemployment surging by 386,000 year-on-year to 1.8 million — now 25 per cent of all unemployed persons [44]. Job openings per unemployed worker fell to 0.9 in December 2025, the lowest since mid-2017 outside the pandemic, confirming a 'low-hire, low-fire' regime where employer leverage has decisively shifted [45]. UK unemployment reached 5.2 per cent in Q4 2025, the highest in nearly five years, with youth unemployment at 16.1 per cent and payrolled employees falling 134,000 year-on-year by January 2026, partly attributed to the April 2025 National Insurance increase [46][47]. The OBR now projects UK unemployment peaking at 5.3 per cent in 2026 [48]. China's manufacturing PMI for February is expected at 49.3, marginally below January's 49.4, extending contraction territory — while the property sector's fifth consecutive year of decline, with an estimated 80 million unsold homes, continues to subtract approximately 0.5 percentage points from annual GDP growth [4][49][50]. Goldman Sachs projects US real GDP at 2.8 per cent, above consensus of 2.2 per cent, but this estimate predates the full energy-shock repricing and may require revision if oil remains above $80 for more than four weeks [37].

Fiscal Dynamics

China's 'Two Sessions' beginning 4 March will signal whether Beijing marks down its GDP target from 'around 5 per cent' to 4.5–5.0 per cent and whether the fiscal deficit widens beyond the base-case 4 per cent of GDP [51][52]. Announced 2026 fiscal measures total 357.5 billion yuan — modest relative to 2025 — with consumer trade-in subsidies narrowed from 12 to 6 appliance categories, indicating a 'quality over quantity' approach [53]. The UK OBR Spring Forecast shows borrowing down nearly GBP 18 billion versus Autumn, with headroom against the stability rule at almost GBP 24 billion, but growth of 1.5 per cent over four quarters remains below historical norms [48][54]. Germany's planned fiscal expansion is expected to add 0.5 percentage points to eurozone growth, partially offsetting the region's structural headwinds of high energy costs, regulatory burden and demographic pressure [37][55]. The US tariff regime — a 10 per cent global tariff under Section 122 following the Supreme Court's 6-3 ruling that IEEPA-based tariffs exceeded presidential authority — has shifted trade flows: US imports from China fell $130.4 billion while imports from Taiwan and Vietnam rose $85.2 billion and $57.3 billion respectively, a diversification pattern that reshapes supply-chain cost structures but does not eliminate tariff pass-through to consumer prices [3][56].

Technology & Systems

AI Infrastructure Spending Under Scrutiny

The rotation out of Magnificent Seven stocks — down 7.0 per cent year-to-date as a basket versus a 7.0 per cent gain for equal-weight S&P 500 — reflects mounting scepticism about the return on AI capital expenditure [8]. Microsoft's 18.6 per cent year-to-date decline is the starkest expression of investor doubt about whether current spending levels translate to near-term revenue [8]. The geopolitical shock has amplified this dynamic by raising the cost of capital (via higher Treasury yields and tighter financial conditions) against which future AI cash flows are discounted, creating a compounding headwind: slower revenue materialisation meets a higher discount rate [13][14]. Samsung Electronics' 10–12 per cent single-day decline and its decision to delay the Taylor, Texas advanced semiconductor facility signals that capital expenditure discipline is tightening at the hardware layer, not just the application layer, with potential knock-on effects for the broader semiconductor supply chain [2][11].

Semiconductor Supply Chains

The Kospi's 7.2 per cent collapse, driven by Samsung and SK Hynix declines of 10–12 per cent each, highlights the concentration risk in memory semiconductor production — South Korea accounts for a dominant share of global DRAM and NAND output [2][11]. Samsung's Taylor, Texas fab 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 [11]. Taiwan's semiconductor exports have surged as US imports from Taiwan rose $85.2 billion under trade diversion from China, but TSMC's facilities remain within the Taiwan Strait risk perimeter, a vulnerability that the Iran conflict has brought into sharper institutional focus [3][56]. The Bank of Canada's framework review explicitly identified supply-chain reconfiguration and AI as structural forces reshaping monetary policy trade-offs, acknowledging that when supply-side developments drive inflation, tightening policy to restrain prices simultaneously weakens the economy — a trade-off now live across multiple jurisdictions [57].

Energy Systems as Systemic Technology Risk

The Iran conflict has exposed a systemic fragility: the global technology supply chain's dependence on stable energy flows through a single maritime chokepoint. Asia absorbs 84 per cent of Hormuz crude and 83 per cent of LNG, and Japan, South Korea and Taiwan — the three pillars of global semiconductor manufacturing — each depend on imported fossil fuels for over 80 per cent of energy supply [2][11]. Qatar's LNG production halt removes roughly one-fifth of global supply, directly threatening the power-intensive fabrication processes that underpin chip manufacturing [10][29]. The feedback loop is structural: energy disruption raises production costs for semiconductors, which raises costs for AI infrastructure, which further compresses the return profile that investors are already questioning, which reduces capital available for capacity expansion. European gas storage at 31 per cent of capacity adds a parallel vulnerability for data-centre operators on the continent who had been expanding on assumptions of stable energy pricing [10].
