When conflict closed the Strait of Hormuz in 2026, Brent crude rose from $71 to a daily high of $138 within six weeks. Oil reaches a household in three rounds: at the pump within weeks, through transport and food over months, and through wages and interest rates over a year or more. The IMF’s rule of thumb is that each 10% rise adds about 0.4 points to global inflation. Importers such as India, Japan and most of Europe feel it most; the household response is a budget that separates fuel from everything else, a buffer, and a plan tested against inflation that stays higher for longer.
On 28 February 2026 military action began in the Middle East and shipping through the Strait of Hormuz, which carries nearly 20% of the world’s oil, effectively stopped. Brent crude, the main international benchmark, rose from $71 a barrel on 27 February to $104 on 9 March1, and reached $138.21 on 7 April2. It fell as low as $69 on 2 July, after the United States and Iran signed an agreement in June to end the conflict3, then rose again with renewed attacks on tankers and on Saudi Arabia’s East-West pipeline, averaging $114 in September4.
Households felt it fast. US petrol prices were 34.2% higher in September 2026 than a year earlier, and energy as a whole 20.4%5. Euro-area energy prices were up 18.8%6. This article sets the 2026 shock beside the five before it, follows a dearer barrel from the oil field to a family’s bills and loans, explains why some countries are hit far harder than others, and ends with what a household can do about it.

In money of the day, oil went from about $2 a barrel in 1972 to about $100 in 2022. Adjusted for inflation the story is less one-way: in constant 2010 dollars the 1980 average was $58.1, against $85.0 in 2022 and a high of $101.6 in 2012, and 2025’s average, $59.5, was about where 1980 stood12. The shocks are spikes on top of a price that rises with everything else.
Brent crude oil, yearly average price per barrel, 1972 to 2025
| In US dollars of the day | In constant 2010 US dollars | |
|---|---|---|
| 1972 | $1.8 | $6.8 |
| 1974 | $11.0 | $29.2 |
| 1979 | $32.1 | $54.2 |
| 1980 | $37.9 | $58.1 |
| 1986 | $14.8 | $21.5 |
| 1990 | $23.7 | $28.6 |
| 1998 | $12.7 | $15.5 |
| 2003 | $28.9 | $36.2 |

Measured from the month before each shock to its peak month, the jumps differ more than the headlines suggest. Brent rose about 110% in 1990, 44% in 2008, and 65% both in 2022 and in 202611. The 1973 embargo, measured on the posted price, was a rise of about 302%9.
How far oil rose in each shock, from before it began to its peak
| Rise in the oil price | |
|---|---|
| 1973–74 embargo (posted price) | 302% |
| 1990: July to October | 110% |
| 2008: January to July | 44% |
| 2022: December 2021 to June | 65% |
| 2026: February to April | 65% |
Round one: the pump. Crude was 51.4% of the US price of a gallon of petrol in 2025; refining, distribution and taxes made up the rest13. Where taxes are a larger share, a crude rise moves the pump price by less in percentage terms. In Delhi on 1 September 2026 a litre of petrol cost ₹102.12, of which state VAT alone was ₹16.598. Some governments also cut duties or subsidise fuel in a shock, which delays the pass-through rather than cancelling it.
Round two: everything that moves. Diesel, jet fuel, fertiliser and plastics all rise, so freight, flights and food follow over the following months as old stock is sold through. Energy is 7.418% of the US consumer price basket and petrol alone 3.853%14, but its effect is larger than its weight because it is a cost inside almost every other item. The IMF’s rule of thumb is that each 10% rise in oil that lasts through most of a year adds about 0.4 percentage points to global headline inflation and takes 0.1–0.2% off world output7.
Round three: wages and expectations. If people come to expect prices to keep rising, pay claims and price-setting follow, and a one-off jump turns into lasting inflation. That is what happened in the 1970s and what central banks act to prevent. US consumer prices were 3.7% higher in September 2026 than a year before5; euro-area inflation was 3.8%6.
India met 88.7% of its crude oil needs from imports in 2025–26 and spent $123.4 billion on them8. In April to August 2026 the crude import bill was $74.8 billion against $50.4 billion a year earlier, about 48% more, on slightly lower volumes8. The Indian basket of crude averaged $90.19 a barrel in August 2026, against $69.11 a year earlier8, and Brent rose by another $23 in September4. A larger import bill also weighs on the rupee, which makes the next shipment dearer again; this is the second line in the diagram above. Japan and most of Europe, which produce little oil of their own, sit in a similar position.
Malaysia sits in between: it produces oil and gas but its households pay for fuel. Bank Negara Malaysia kept its policy rate at 2.75% in September 2026, with headline inflation averaging 1.8% in the first seven months, but said inflation was expected to stay elevated as energy costs passed through to consumer prices with a lag15.
Exporters such as the Gulf states, Norway and Canada earn more when oil rises, which supports government budgets and, in Canada and Norway, often the currency. For an Indian family working in Dubai the effect is mixed: the Gulf economy may be stronger, but money sent home buys a costlier tank of petrol in India, and a conflict in the region can threaten the job itself. See money across countries for how currency and location interact in a plan.
Central banks cannot make oil cheaper, but they can try to stop round three. In 1979–81 the Federal Reserve under Paul Volcker raised its policy rate from 11% to a peak of 19% in 1981, and the US went into its most severe recession since the Great Depression10. In July 2008, with oil near its peak, the European Central Bank raised its main rate to 4.25%16, weeks before the financial crisis forced it into reverse.
In 2026 the pattern repeated, more gently. The ECB raised its deposit rate from 2.00% to 2.25% from 17 June and to 2.50% from 16 September16. The Federal Reserve raised its target range by a quarter point to 3.75–4.00% in September17. The Reserve Bank of India raised its repo rate by 25 basis points to 5.50% on 7 October, moving to a stance of “calibrated tightening”, and projected inflation of 5.2% for 2026–2718. For a household with a floating-rate home loan, an oil shock can therefore arrive twice: at the pump, and months later in the repayment. Interest rates and your money explains how a rate change reaches a mortgage, an EMI or a deposit.

Directly through fuel and heating, then through transport, food and goods. The IMF’s rule of thumb is that a lasting 10% rise in oil adds about 0.4 percentage points to global headline inflation7.
Military action in the Middle East from 28 February effectively closed the Strait of Hormuz, which carries nearly 20% of global oil supply1. Brent peaked at $138.21 on 7 April and surged again in September after pipeline attacks2,4.
On EIA’s daily Brent spot series the high is $143.95 on 3 July 20082. The 2026 daily high, $138.21 on 7 April, came close2. Adjusted for inflation, the highest yearly average on the World Bank’s series is 2012’s, $101.6 in 2010 dollars, against $94.9 for 2008 and $58.1 for 198012.
India met 88.7% of its crude oil needs from imports in 2025–26, at a cost of $123.4 billion8.
The US dollar index fell 10.8% in the first half of 2025, its worst start to a year since 1973, and the Fed’s broad dollar index ended 2025 down 7.4%. In 2026 the dollar steadied, and the rupee fell to record lows near 97 as oil surged. The same S&P 500 returned 16.4% in dollars in 2025, 2.7% in euros and 22.2% in rupees. What matters for a family is not which way the dollar moves but whether its savings are in the currency it will spend.
US tariffs rose in 2025 to their highest average level in about ninety years, were cut back by a Supreme Court ruling in February 2026, and were rebuilt under other laws. Research finds the cost lands mostly on buyers in the importing country, spread across importers, shops and households; Yale’s Budget Lab puts it at about $1,100 a year for the average US household. Elsewhere the effect arrives through export orders, jobs, markets and interest rates. The useful response is a budget that knows which costs are rising, a cash buffer sized to your job’s exposure, and no trading on headlines.
Compare rent with the unrecoverable cost of owning — interest, upkeep, property tax and the return your deposit gives up, less expected price growth — not with the mortgage payment. At autumn 2026 rates, owning the average London home costs somewhat less than renting it, an Austin home costs far more to own than to rent, and an HDB flat in Singapore costs far less. Transfer taxes then decide how long you must stay.
