The escalation of conflict involving Iran has begun to register in real-time economic indicators and market prices, with immediate implications for this week's key releases: purchasing managers' indices (PMIs), consumer confidence readings and headline inflation prints. Financial markets have already priced a risk-premium into energy and freight, with the Financial Times reporting on 22 March 2026 that Brent futures were roughly 7% higher since the early-March escalation (FT, 22 Mar 2026). Central banks and corporates will be watching scheduled data points closely because a sustained price shock to energy could push headline inflation and inflation expectations higher, compressing the policy margin for economies with still-elevated core inflation. The flow of data over the next two weeks — including national PMIs, consumer surveys and official CPI releases — will determine whether markets treat the shock as transitory or call for a reassessment of the global inflation trajectory. This piece dissects the near-term transmission channels of the Iran shock into macro data, quantifies likely magnitudes using market signals and provides a Fazen Capital perspective on what the numbers may imply for policy and asset allocation decisions.
Geopolitical events historically translate into macro data through commodity prices, trade disruption and shifts in risk sentiment. For the current episode, oil and shipping rates are the primary transmission channels. The FT's March 22 dispatch cited a roughly 7% rise in Brent since the early-March escalation (FT, 22 Mar 2026), and market-implied volatility in Brent (one-month) has climbed to levels consistent with heightened supply-risk pricing. Higher energy input costs tend to show up first in headline consumer price indices and in survey-based inflation expectations; subsequently, they filter into manufacturing input costs and service-sector pricing depending on the supply-chain pass-through and wage dynamics.
The calendar amplifies the importance of this episode. Several large economies will print PMI data and consumer confidence surveys in the coming days, and these survey metrics often lead official CPI prints by several weeks. For example, S&P Global PMIs act as an early indicator of business conditions and price pressures: a divergent PMI sequence where input-price components rise while output components soften would signal stagflationary tendencies. The FT notes the immediate focus on PMI and consumer data (FT, 22 Mar 2026); market participants will be analyzing not just headline PMI but the input-price sub-indices and supplier delivery times to adjudicate the durability of cost pressures.
A third contextual vector is policy posture. Central banks in advanced economies have limited room to accommodate energy-driven inflation without risking credibility on inflation targeting. The next round of official CPI prints will be watched against the backdrop of policymakers' recent communications. If headline inflation jumps materially above expectations — even if driven by energy — central banks will need to weigh the cost of treating a supply shock as a transient blip against the risk of second-round effects on wages and core inflation.
Oil and freight provide the clearest near-term signals of real-economy spillovers. As reported by FT on 22 March 2026, Brent futures were approximately 7% higher since early March (FT, 22 Mar 2026). Shipping costs, as measured by the Baltic Dry Index or relevant tanker freight indices, have shown acute sensitivity in past Middle East disruptions; a sustained 20–30% move in key freight rates within a fortnight materially raises import costs for energy-importing economies. Those cost increases are reflected earlier in PMIs' input-cost gauges: in previous episodes — for instance, during the 2019 Persian Gulf tensions — the PMI input-price components rose by roughly 4–6 index points within two survey cycles.
Survey data due this week will be particularly informative. If S&P Global and national PMIs report an increase in input-price readings of 3–5 points while output indices contract or stagnate, that pattern would resemble a classic cost-push episode — higher costs but weaker demand. Consumer confidence is the equally important demand-side counterpart: a drop in headline consumer confidence (for example, a fall of 5–10 index points sequentially) historically precedes weakness in retail sales and consumption in the next one-to-two months. The FT highlighted both PMI and confidence as near-term watchpoints (FT, 22 Mar 2026).
Official CPI releases will be the ultimate test of pass-through. A back-of-envelope sensitivity suggests that a persistent $5–8/bbl rise in Brent, sustained for a month, can add roughly 0.1–0.3 percentage points to monthly headline CPI in large energy-importing economies, depending on tax structures and fuel pass-through. That magnitude is sufficient to move headline rates by several tenths of a percent on the monthly print and could alter year-on-year comparisons; markets are particularly sensitive to shifts that push inflation away from recent trends and central bank projections.
Energy and logistics-related sectors are the most immediate beneficiaries of higher energy prices; exploration and production names and tanker freight firms typically outperform in the first 30 days of a Middle East supply scare. Conversely, sectors with high energy intensity — airlines, chemicals and certain heavy manufacturing — face margin compression. In equities, this dynamic often leads to a divergence versus indices less sensitive to commodity prices: energy sector returns may outpace the broader market by mid-single to double-digit percentage points over the first month, while cyclical industrials lag.
Fixed income markets price geopolitical risk through sovereign spreads and inflation breakevens. A sustained move that raises inflation breakevens by 15–30 basis points would increase nominal yields across the curve as markets reprice expected real rates and inflation compensation. Emerging-market sovereigns with large energy import bills could see spread widening of 30–100 basis points depending on previous vulnerability and FX reserves. As an example of relative risk, energy-exporting peers typically experience spread compression and currency appreciation versus energy importers during such episodes.
Currency markets also react quickly: commodity-linked currencies (Norwegian krone, Canadian dollar) usually strengthen on oil-related risk premia, while import-dependent currencies (e.g., Turkish lira, Egyptian pound) can weaken. The policy implication for central banks in vulnerable countries is nontrivial: defending exchange rates could entail rate hikes even as growth slows, exacerbating local downturn risks.
Three principal risks will determine the scale and persistence of data spillovers: (1) duration and scope of the military escalation affecting shipping lanes; (2) the response of global inventories and spare capacity (notably OPEC+ output behaviour); and (3) secondary macro reactions, including consumer sentiment and wage setting. If spare capacity and strategic reserves are deployed quickly — and if trade flows largely continue albeit at higher cost — the inflation impulse may be transitory. By contrast, disruption to Red Sea or Strait of Hormuz transit routes that lasting weeks could materially alter global supply chains and energy availability, increasing the odds of second-round inflation effects.
Model uncertainty is acute. Historical analogues (2019 Gulf tensions, 2011 Arab uprisings) provide partial guidance but different baseline macro conditions matter: global core inflation today in many economies remains nearer to 2–3% than the double-digit regimes of the past, so pass-through dynamics could be nonlinear. Policymakers face a risk of acting too early on headline inflation versus the risk of conceding inflation persistence. Markets themselves can amplify outcomes: risk-off flows into safe assets and currencies can tighten financial conditions, reinforcing a demand-side contraction that counteracts cost-push inflation.
Market-implied probabilities and scenario analysis are therefore essential. Investors and corporates should run at least two scenarios: a short-lived supply shock (two–four weeks) with limited pass-through, and a protracted shock (two+ months) with inventory depletion and deeper supply-chain impact. The difference between the scenarios can be several tenths of a percentage point in headline CPI and materially different for corporate margins and sovereign spreads.
Fazen Capital assesses that the most likely near-term outcome is a partial and uneven pass-through: headline energy prices will remain elevated relative to pre-escalation levels for several weeks, producing measurable but not runaway increases in headline inflation for major energy importers. Our base-case scenario assigns roughly a 60% probability to a scenario where Brent remains elevated by 5–10% over a one-month horizon, delivering a 0.1–0.2 percentage-point uplift to monthly CPI prints in large importers, consistent with a limited policy response from rate-setting committees that prioritise medium-term inflation control over short-lived supply shocks.
A contrarian element of our view is that the market reaction so far may underestimate the potential for compositional effects on inflation — specifically, the risk that energy-induced costs compress real incomes enough to alter wage-bargaining outcomes in sectors with tight labour markets. If wage growth re-accelerates even modestly (0.3–0.5 percentage points above expectations), central banks will confront a higher hurdle to declare the shock transitory. This pathway would raise the odds of a shift in policy expectations and a repricing of rates and break-evens beyond current market-implied levels.
Operationally, we recommend that institutional risk managers integrate high-frequency indicators — daily freight indices, refinery utilisation rates and weekly oil inventories — into scenario runs for near-term exposure monitoring.

Q: How quickly do PMIs translate into official CPI prints?
A: Historically, PMIs act as forward indicators with a lead of one to three months for components that feed into manufacturing prices and input costs. In cost-push episodes, the PMI input-price subindex often leads headline CPI by roughly four to eight weeks because firms report higher input costs before those costs are fully reflected in consumer prices.
Q: Could central banks look through this shock without changing policy?
A: Yes — if the shock is clearly temporary and survey-based measures of inflation expectations remain anchored. Central banks typically look at core inflation and indicators of second-round effects; a one-off energy price spike that does not materially affect wages or services inflation is more likely to be treated as transitory. However, if market-implied inflation breakevens and wage surveys move materially, the likelihood of a policy response rises.
The Iran-related escalation has already lifted energy risk premia and created a non-trivial upside risk to near-term headline inflation; the coming PMI, consumer confidence and CPI releases over the next two weeks will be decisive in determining whether the shock is transient or inflationary. Monitor PMI input costs, consumer sentiment and oil/freight indices closely for early evidence of pass-through.
