The Iran conflict pushed the price of 500 litres of home heating oil from under €500 to €833 in early March, leaving many households facing an immediate cash squeeze. RTÉ reported the jump followed a wholesale rise from roughly $72 a barrel to above $91 in the first weeks of the conflict, and some forecourts briefly charged about €1.80-€1.90 per litre for petrol and diesel. Truckers, farmers and contractors staged convoys and blockades that slowed terminals and central Dublin traffic, and the Government cut excise, delayed a carbon-tax rise by six months, offered handouts for hauliers and unveiled a €505 million rescue package; forecasters including the ESRI and the Central Bank revised their March 2026 outlooks, warning of higher inflation and disproportionate effects on lower-income households.

The immediate numbers are stark. RTÉ documented how the price for 500 litres of home heating oil, a benchmark purchase for many Irish households, climbed to €833 in early March from under €500 just days earlier. That squeeze didn't come out of nowhere. RTÉ recorded a wholesale oil move from about $72 a barrel to above $91 in the weeks after the conflict began, and retail prices followed quickly.

Retail moves were rapid and uneven. TheJournal.ie and other Irish outlets tracked pump-price increases of up to 16 cent per litre, and fuel-card suppliers notified customers of 12.5 cent-per-litre hikes. Some forecourts were selling petrol and diesel at roughly €1.80-€1.90 per litre. Industry voices warned diesel could top €2 a litre, a prospect that pushed hauliers, farmers and busy contractors to the limits of their cashflow.

From price spikes to paralysis

The price shock was compounded by physical and political disruption. Truckers, farmers and contractors organised convoys and blockades that targeted three refineries and main terminals, actions that brought central Dublin traffic to a standstill on occasion. Contemporary coverage noted that representative industry bodies said they were not officially part of those blockades, even as terminals and roads experienced real disruption.

Protests and targeted action had two effects. They raised the political salience of rising fuel costs, and they interrupted the normal logistics that smooth short-term supply blips. That combination produced market paralysis in places. Forecourts that couldn't get timely deliveries bumped prices higher, and some households and businesses responded by hoarding, reinforcing the short-run squeeze.

Policy relief, forecasts and second-order impacts

The Government moved quickly to blunt the immediate pain. Officials announced excise duty cuts, delayed a planned carbon-tax increase by six months, offered handouts for hauliers and unveiled a €505 million rescue package intended to relieve fuel-cost pressure.

Mastheads

An academic source described those measures as temporary relief that shields motorists and businesses from the international energy shock.

Macro forecasters then revised their views. The Economic and Social Research Institute raised its headline inflation forecast to 3.2% for the year from 2.1%. The Central Bank warned headline inflation could reach as high as 4.2% in the months ahead if the conflict persisted. This Central Bank also noted that lower-income households would be disproportionately affected and that higher energy costs would feed through to many goods and services.

Transport and travel sectors are already feeling the strain. Testimony to the Oireachtas transport committee cited International Air Transport Association data showing roughly a 50% rise in jet-fuel costs since strikes began, a pass-through the committee heard could translate into higher air fares. Airlines and other transport operators have little margin to absorb sustained fuel-price rises.

There are tentative signs of structural shifts. One outlet recorded a 51% jump in electric-vehicle sales in continental Europe in March, framing the conflict as both immediate price pain and a possible accelerant to electrification. At the same time, analysts warned that political pressure on governments could lead to policies that temporarily subsidise fossil-fuel consumption, which would blunt carbon-pricing signals and make the transition.

Not all accounts line up neatly. Wholesale oil series diverge across reports. RTÉ cited a move from roughly $72 to above $91 a barrel in the immediate aftermath, while TheJournal.ie described Brent trading in the $77-$80 range after a late-February rise from the mid-$60s. Sources used different benchmarks and timestamps, producing a range rather than a single consensus figure. One report framed the Hormuz disruption as the "biggest energy crisis in history", a description attributed to a single outlet, The Guardian, and presented as framing rather than a price metric.

The exact composition and targeting of the government relief has also been contested. Academic critics questioned whether the measures disproportionately benefit higher-income households rather than essential operators, a point that sits in tension with official messaging on the package’s objectives. Those debates matter, because how support is structured will alter both fiscal cost and the price signals households and firms face.

For ordinary households the immediate effect is practical and painful. Heating bills and filling the car became causes of urgent cash-management decisions. For firms that rely on diesel and jet fuel, the shock is a hit to margins and to planning. For policymakers the test is two-fold. They must provide relief that prevents immediate hardship, and they must avoid measures that permanently distort incentives for energy use at a time when long-term transitions are also on the agenda.
