Iran and Oil: The Invisible Tax Your Small Business and Your Bills Will Pay

Every time an armed conflict breaks out in the Middle East, public debate fills up with maps, military analysts and barrel counts. Hardly anyone stops to consider what seems to me the essential point: a crisis around Iran is, in practice, a tax nobody voted for, and it ends up being collected from the till of Spain’s self-employed and small businesses. My thesis is simple and, I think, uncomfortable: the biggest risk is not the war itself, but our habit of treating it as international news rather than as a line item in the cost base.

Why Iran affects us even though it is far away

Iran is not just a significant crude producer. Its strategic weight comes from geography: it sits next to the Strait of Hormuz, one of the maritime chokepoints through which a very large share of the world’s traded oil and liquefied natural gas passes. That passage doesn’t have to close for there to be consequences; it is enough for markets to price in the possibility. Risk premiums, freight rates and marine insurance climb before a single drop is missing.

Spain imports the vast majority of the fossil energy it consumes. That makes us particularly sensitive to any shock in international prices, and it does so in a rather undemocratic way: fuel feeds into the cost of logistics, farming, construction, retail and, of course, freelance transport. Even if your business doesn’t burn a litre of diesel, your suppliers do, and they will pass the cost on to you with a slight delay.

The real blow: inflation coming in through the back door

Headlines fixate on the price of petrol, but the most corrosive effect is the indirect one. Energy makes transport more expensive, transport makes products more expensive and, from there, the increase spreads to wages and rents. Central banks know this well: a supply shock is the worst possible scenario, because it forces a choice between fighting prices, which slows the economy, or tolerating them, which risks letting them become entrenched. Either route is paid for in higher interest rates for longer or in lower activity.

For a small business, that translates into a familiar squeeze: costs that rise fast and selling prices that can’t be raised at the same pace without losing customers. Those who haven’t measured how much of their margin depends on energy and raw materials discover the problem once it is already in the quarter’s accounts. And here I see a recurring mistake: confusing revenue with financial health. You can sell more and earn less.

Nor should we ignore the tax angle. A price shock is usually accompanied by temporary aid, energy tax cuts or transport subsidies, and later by their withdrawal. Anyone who plans without reading the small print and the expiry date of each measure risks seeing a discount vanish just when it was needed most. Emergency measures are, by definition, temporary; businesses should not be built on them.

What I would do if I ran a small business this week

I am not in favour of alarmism or of paralysis. I advocate, rather, a kind of financial hygiene without the drama:

First, know the real weight of energy and transport in your cost structure, both direct and indirect. Without that number, every decision is guesswork. Second, review the price-adjustment clauses in your contracts with customers and suppliers: many small businesses sign at a fixed price and shoulder alone the risk the market hands them. Third, manage cash with more caution than optimism: a liquidity cushion is worth more than any growth forecast. And fourth, adjust instalment payments and provisions to the reality of the business, not last year’s, so you don’t end up financing the tax authorities with money the company will need in a few months.

It is true that no freelancer can prevent a geopolitical crisis. But they can decide whether or not it catches them off guard. The difference between the two is usually a good dashboard and an adviser who looks at it with you before the quarter closes.

At Zythos Business, this is exactly where we work: we help freelancers and small businesses understand their real costs, tailor their tax position to their situation and anticipate cash flow before international noise turns into a cash problem. If you want to know what an energy shock would really cost you, let’s start with your numbers.
