The price of oil has turned upward again - not because the world is consuming more, but because it doesn't believe peace will hold. After the collapse of talks between the US and Iran in Switzerland, the markets reacted the way they always react to uncertainty: with a price spike.

Brent crude rose 0.64 percent, to 80.36 dollars a barrel, while American WTI gained 1.7 percent, to 77.88 dollars. The trigger isn't only the failed talks - the cancellation of Vice President Vance's trip added doubt, and intensified Israeli operations in Lebanon pushed the geopolitical risk even higher. Still, despite the daily gain, both benchmarks are heading toward a drop of about 8 percent this week - proof of how nervous and jittery the market is.

Behind the numbers lies a far more practical question for the ordinary citizen: every move in global oil sooner or later reaches the pump. When the price spikes over tensions thousands of kilometers away, we pay the consequences when we fill the tank, even though we have nothing to do with any of the conflicts.

Analysts are watching the Strait of Hormuz closely - the narrow passage through which a large share of the world's oil flows. One move there is enough to send prices flying. And the Balkans, as always, will feel it last and hardest: small economies have no reserve to cushion other people's crises, only a bill that the household ends up paying.
