Crude oil is the lifeblood of the global industrial economy, yet the journey from a subterranean reservoir to a litre of petrol at the forecourt involves a cascade of physical transformations, commercial transactions, and fiscal interventions that profoundly shape who bears the cost, and how much. A sudden shift in the world market price of crude, whether triggered by OPEC+ supply discipline, geopolitical disruption, or a demand shock, does not translate uniformly into consumer prices across the globe. The consequences are systematically different, depending on a country’s tax policy, exchange rate, efficiencies in refining processes, distribution processes and dependence on energy imports.

The Refining Process: From Crude to Finished Products

Crude oil is a naturally occurring mixture of hydrocarbons and its chemical composition varies by field: Heavy sour crudes from Venezuela, or Saudi Arabia, require additional processing, raising refining costs by USD 2–5 per barrel. One standard barrel contains approximately 159 litres.

Crude oil is preheated to approximately 370–400°C and the operating principle exploits differences in boiling points. The resulting fractions, collected from top to bottom, include: light petroleum gases (LPG) boiling below 40°C; naphtha and gasoline fractions in the 40–205°C range; kerosene and jet fuel between 175°C and 275°C; diesel and gas oil from 250°C to 350°C; and atmospheric residue above 350°C which is then processed in a vacuum distillation unit to recover further distillates, including lubricating oil base stocks.

Primary distillation alone is insufficient to meet market demand. Gasoline demand far exceeds the natural yield of the distillation cut. A modern complex refinery achieves the following approximate product yields from a light sweet crude: petrol/gasoline ~45%; diesel/gasoil ~25%; kerosene/jet fuel ~10%; LPG ~5%; heavy fuel oil ~10%; and other by-products ~5%. These ratios shift with crude quality and refinery configuration, and response differently to crude price changes.

The Crude Truth: How Oil Prices Punish the Poor Twice

An accounting perspective reveals a waterfall of costs, each layer added by a distinct economic actor and subject to a distinct set of market forces and regulatory interventions. A companion of the approximate cost structure for a litre of petrol at the retail level, assuming a crude oil price of USD 70 per barrel (approximately USD 0.44 per litre of crude equivalent), between advanced and emerging economies, can be explained in four layers:

Layer 1 — Crude Oil Cost (~51% of Retail Price)

The foundation of every fuel product is the crude oil acquisition cost. At USD 70/barrel, the raw material cost embedded in one litre of refined petrol is approximately USD 0.44. This figure includes wellhead lifting costs, field operating expenses, royalties, and sovereign resource taxes paid to the producing country, as well as freight and insurance for ocean tanker shipment.

For emerging economies, without domestic refining capacity, or with currencies that are not freely convertible, this layer is doubly exposed: a crude price increase is compounded by any simultaneous depreciation of the local currency.

Layer 2 — Refining Margin (~20% of Retail Price)

The gross refining margin, measured by the industry’s standard 3-2-1 crack spread;

Crack Spread (gross refining margin) = (2×Gasoline Price) + (1×Diesel Price) − (3×Crude Price)

Critically, this gross figure must not be confused with profit. A refinery typically uses 6–8% of its own crude input as process fuel, and significant variable operating costs. This gross refining margin, the difference between the value of products produced and the cost of crude, varies considerably with market conditions.

In advanced economies with large, integrated refinery systems, these margins are moderated by competition and long-term supply contracts. In emerging economies, dependent on a single import refinery or on product imports rather than crude, refining costs are effectively set by the international product market, leaving little domestic control over this cost layer.

Layer 3 — Distribution and Marketing (~11% of Retail Price)

Refined products must travel from the refinery gate to the consumer through a distribution network involving primary pipelines or product tankers, regional storage terminals, secondary truck distribution, and retail fuel stations. In advanced economies, this infrastructure is mature, privately operated, and highly efficient, contributing a relatively stable USD 0.05–0.10 per litre to the retail price. In many emerging economies, the distribution infrastructure is fragmented, underdeveloped, or state-controlled, introducing additional costs, quality inconsistencies, and opportunities for rent-seeking. In Sri Lanka, for instance, the state-owned Ceylon Petroleum Corporation has historically cross-subsidised distribution costs, masking the true economic cost until subsidy withdrawal forced rapid price adjustments in 2022.

Rent-Seeking is extracting value without creating value; essentially corruption and inefficiency

Licensing corruption:Limited fuel station licenses create artificial scarcity; Licenses sold/traded at premiums; Political connections needed to obtain licenses

Quality adulteration: Consumers pay for “petrol” but get lower-quality mix

Quota manipulation:Subsidised kerosene (meant for poor households) diverted to diesel mixing; Creates black markets during shortages

Phantom costs:

Layer 4 — Taxation (18–60% of Retail Price)

Taxation is the most variable, politically sensitive, and analytically important layer in the cost structure. In advanced economies a high tax bases serve a dual purpose: generating substantial fiscal revenue and acting as an automatic price stabiliser. When crude rises, the absolute tax component remains constant, so the percentage of the price attributable to crude increases less than proportionately at the retail level.

In contrast, emerging economies historically imposed low fuel taxes or active subsidies, particularly for diesel, LPG, and kerosene used by low-income households. Sri Lanka’s fuel tax component, prior to the 2022 crisis, was, they claim, effectively negative in real terms due to administered pricing below cost.

The Impact of a Crude Price Increase: Advanced vs. Emerging Economies

For example, if crude oil rises from USD 70 to USD 85 per barrel, an increase of approximately 21.4%. The mechanisms by which this shock is transmitted to consumers, and the capacity of economies to absorb or redistribute it, diverge dramatically along the advanced/emerging economy divide (Table 1).

Absorb shocks through tax relief

Advanced economies possess well-established fiscal frameworks that enable them to absorb temporary commodity shocks through tax relief, targeted transfers, or direct subsidies without compromising fiscal sustainability. Research by the Center for Global Development (2026) estimates the median fiscal cost of shielding consumers from the crude price increase of USD 15 scenario at approximately manageable cost of 0.4% of GDP for advanced economies.

Emerging economies face median fiscal costs of approximately 0.9% of GDP — effectively double. For Sri Lanka, entering the 2022 energy crisis with near-zero foreign reserves, even a temporary subsidy was fiscally impossible, forcing an immediate and politically destabilising pass-through of the full price increase to consumers. The lesson is stark: the ability to smooth out a commodity price shock across time is itself a function of prior fiscal strength, making the poor more vulnerable precisely because their governments are already under strain.

Inflation Pass-Through and Monetary Policy Credibility

The second transmission mechanism operates through the consumer price index and central bank behaviour. In advanced economies, fuel typically represents 3–5% of the CPI basket, and central banks enjoy high credibility in anchoring inflation expectations.

In emerging economies, fuel and food together often constitute 40–60% of CPI baskets, and central banks have historically struggled to maintain credible inflation targets. A 21% crude price increase translates into a far larger initial CPI shock. Worse, the loss of inflation credibility means that workers and businesses adjust wages and prices preemptively, generating persistent second-round inflation (> Double). To defend its inflation target, the emerging economy central bank must raise interest rates aggressively, simultaneously raising the cost of borrowing for businesses and governments, a painful policy dilemma in an economy already under stress.

Structural Current Account Vulnerability

The third and perhaps most structurally significant difference lies in the current account and foreign exchange dynamics. The advanced economies hold large reserve currencies and deep financial markets that allow them to finance import cost increases without immediate exchange rate pressure.

Sri Lanka, by contrast, allocated approximately 23% of its total import bill to petroleum products. A USD 15/barrel price increase instantly widens the current account deficit of these economies, depleting foreign exchange reserves. As reserves fall, currency markets anticipate further depreciation, precipitating speculative selling of the domestic currency. The resulting exchange rate depreciation, potentially 5–15% in a shock scenario, multiplies the cost of crude imports in local currency terms. A 21% USD price increase thus becomes a 28–39% local currency price increase at the refinery gate, before any refining, distribution, or tax component is added. This vicious cycle; crude price rise → reserve depletion → currency depreciation → amplified import cost → further reserve depletion, is a hallmark of emerging economy energy crises, and Sri Lanka’s 2022 experience illustrated it in extreme form.

Double bind when crude rises and subsidised

Countries that have historically subsidised fuel face a double bind when crude rises: the subsidy bill expands sharply (as the gap between subsidised price and market cost widens), while fiscal space contracts. The International Monetary Fund has consistently recommended subsidy reform, allowing fuel prices to reflect market cost while protecting the poor through direct cash transfers, as the fiscally sustainable path. Sri Lanka’s forced price liberalisation in 2022 (under IMF programme conditions) illustrate both the political difficulty and the macroeconomic necessity of this adjustment.

The Asymmetry of Oil Price Responses: Advanced vs. Emerging Economies

Advanced economies enjoy bidirectional flexibility in responding to oil price volatility; prices rise and fall with crude markets, leaving fiscal positions largely neutral. Emerging economies, by contrast, face a structural trap: when crude rises, subsidy bills explode, draining public finances; when crude falls, governments retain windfall savings to offset accumulated deficits rather than passing relief to consumers. Sri Lanka’s cycle from collapse to liberalisation to renewed subsidies illustrates this vividly. Underlying this is a political economy ratchet, price hikes are unavoidable, but reductions are politically captured, making permanent reform structurally elusive.

Life keeps throwing hurdles in his way, but Eshan Malinga keeps vaulting over them. Take his February from hell. For several months, Malinga had been building up to his first ever World Cup, a dream for pretty much anyone who ever picks up a cricket ball. But a week before that World Cup, Malinga dislocated his non bowling shoulder while bowling, which the team’s medical staff have since described as a freak injury they had never seen before.

“I was devastated,” Malinga says. “On top of it being my first World Cup, it was also at home and I didn’t know when I would get that chance again. There were a few days there where I did absolutely nothing.”

And yet in mid-May, here he is grinning from atop a pile of 16 IPL wickets,  having developed a serious reputation as a reverse-swing operator. Sunrisers  Hyderabad’s  explosive batters may have seized the spotlight in this frenetic IPL, but on the bowling front, no SRH bowler has neared Malinga’s wicket haul, which is fifth best in the season overall.  In a year in which they have not had Pat Cummins for seven of their 11 matches, it is Malinga who has held down the fort,  particularly in the second half of the innings.

The death of the most important suspect in the Sri Lankan Airlines Airbus deal has drawn intense public speculation. Kapila Chandrasena the former CEO of the heavily loss-making national airline was found dead under circumstances that the police are still investigating.

He had recently been arrested by the Commission to Investigate Allegations of Bribery or Corruption in connection with the controversial Airbus aircraft purchase agreement signed in 2013. Police investigations are continuing into the cause of death and whether or not he committed suicide. The unresolved death brings to light the high stakes involved in accountability efforts of this nature.

The uncertainty surrounding Chandrasena’s death has revived public memories of other mysterious deaths linked to corruption investigations and public scandals. Among them is the death of Rajeewa Jayaweera, a former SriLankan Airlines executive and outspoken critic of the Airbus transaction. He was following in the tradition of his father, the late foreign service officer and public servant Stanley Jayaweera who mentored the younger generation in good governance practices and formed the group “Avadhi Lanka” along with icons such as Prof Siri Hettige. Rajeewa had written a series of articles exposing irregularities in the deal before he was found dead near Independence Square in Colombo in 2020. The CCTV cameras in that high security area were turned off. Questions raised at that time whether or not he had committed suicide were not satisfactorily resolved.

The controversy about the cause of Chandrasena’s death is diverting attention away from the massive damage done to the country by the SriLankan Airlines deal itself. The value of the aircraft agreement was close to the size of the International Monetary Fund bailout package that Sri Lanka desperately needed by 2023 in order to stabilise the economy after bankruptcy. Sri Lanka’s IMF Extended Fund Facility amounted to about USD 3 billion spread over four years. The comparison shows the scale of the losses and liabilities that irresponsible and corrupt decisions have imposed on the country and which must never happen again.

Wider Pattern

The corruption linked to the Airbus transaction came fully into the open only because of investigations conducted outside Sri Lanka. In 2020 Airbus agreed to pay record penalties of more than EUR 3.6 billion to authorities in Britain, France and the United States to settle global corruption investigations. Sri Lanka was identified as one of the countries where bribes had allegedly been paid in order to secure contracts. The Airbus deal involved the purchase of six A330 aircraft and four A350 aircraft valued at approximately USD 2.3 billion. Investigations showed that Airbus paid bribes amounting to nearly USD 16 million in order to secure the contract. According to court submissions, at least part of this money amounting to USD 2 million was transferred through a shell company registered in Brunei and routed through Singapore bank accounts linked to the late airline CEO and his wife.

The commissions involved in this deal may seem comparatively small compared to the overall value of the contracts but devastating in their consequences. But they also show that a few million dollars paid secretly to decision makers could lead to the country assuming liabilities worth hundreds of millions or even billions of dollars over decades. This is why corruption is not simply a moral issue. It is a direct economic assault on the living standards of ordinary people. Money lost through corruption is money unavailable for schools, hospitals, rural development and job creation. In the end the burden falls on ordinary citizens who are left to repay debts incurred in their name without receiving commensurate benefits in return.

The SriLankan Airlines transaction gives an indication of the wider pattern of corruption and misuse of national resources that has taken place over many years. This was not an isolated incident. There were numerous large scale infrastructure and procurement projects that imposed heavy debts on the country while enriching politically connected individuals and their associates. Other projects such as the Colombo Port City, Hambantota Harbour and highway construction reveal a similar pattern.

Less publicised but equally damaging scandals have involved fertiliser medicine and energy contracts. Investigations into medicine procurement in recent years uncovered allegations that substandard pharmaceuticals had been imported at inflated prices causing both financial losses and risks to public health.

Moral Renewal

The present government appears determined to investigate major corruption cases in a manner that no previous government has attempted. Those who ransacked and bankrupted the treasury need to be dealt with according to the law. There is considerable public support for efforts to recover stolen assets and ensure accountability.

In his May Day speech President Anura Kumara Dissanayake stated that around 14 corruption cases were nearing completion in the courts this very month and called upon the public to applaud when verdicts are delivered. Political opponents of the government claim that such comments could place pressure on the judiciary and blur the separation between political leadership and the courts. But the deeper public frustration that underlies the president’s remarks also needs to be understood.

The challenge facing Sri Lanka is twofold. The country must ensure that justice is done through due process and independent institutions. If anti corruption campaigns become politicised they can lose legitimacy. But if corruption and abuse of power continue without consequences the country will remain trapped in a cycle of economic decline and moral decay. Sri Lanka also needs to confront past abuses linked to the war period. There are allegations of kidnapping, extortion, disappearances and criminal activity in which members of the security forces have been implicated. Vulnerable sections of the population suffered greatly during those years. If political leaders turned a blind eye or actively connived in such crimes they too need to be held accountable under the law. Selective justice will not heal the country. Accountability must apply across the board regardless of political position, ethnicity or institutional power.

Sri Lanka has paid a very heavy price for corruption and impunity. The economic collapse of 2022 did not occur overnight. It was the result of years of bad governance, reckless decision making, abuse of power and the misuse of public wealth. If the country is to move forward the focus cannot be diverted by sensational speculation alone. Suspicious deaths and political intrigue may dominate headlines for a few days. But the larger issue is the system that enabled corruption to flourish without accountability for so long. The real national task is to end that system. Sri Lanka cannot build a prosperous future on a foundation of corruption and impunity. Unless those who looted public wealth are held accountable and the systems that enabled them are dismantled, the country risks repeating the same cycle again.
