Oil is starting to send a signal. Brent crude just moved above $82.50 per barrel. Gas prices are already up almost 20% since January. When oil moves like this, it affects everything. Transport gets expensive. Food and goods cost more. Inflation pressure grows. That’s why oil often becomes an early warning for markets. If prices keep climbing toward $100, pressure on governments will rise quickly. And when that happens, markets usually start expecting a deal or some kind of intervention. For now, oil is the number to watch.
