An economic analysis released this week estimates that the military confrontation between the United States and Iran has added roughly $121 billion to American energy bills since it began in February. According to Moody's Analytics, the average US household has spent an extra $1,760 overall, with energy costs accounting for more than half of that burden.
The conflict, initiated by President Donald Trump without explicit congressional approval, has triggered sharp global energy price spikes. Iran's closure of commercial shipping through the Strait of Hormuz—a chokepoint for about a fifth of global oil supply—has sent shockwaves through markets from Tokyo to Mumbai.

Mark Zandi, chief economist at Moody's, told CNBC that the figures reflect the intense financial pressure on American consumers. Beyond energy, households are also paying an estimated $425 more in interest costs and $405 in higher military spending, which Zandi said would ultimately be financed through expanded national debt or increased taxes.
The strain is not confined to the United States. Karthik Sankaran, a senior research fellow in geoeconomics at the Quincy Institute for Responsible Statecraft, warned that recent developments—including Houthi fighters seizing a key Red Sea port and a drone strike on a Saudi oil pipeline—suggest relief could be distant. He noted that the world has far fewer buffers now than at the conflict's start.
“Seaborne storage on tankers has been depleted,” Sankaran wrote. “The US Strategic Petroleum Reserve has released about 130 million barrels, and the world's largest importer, China, is increasing imports to 7.2 million barrels per day, up from a low of 6 million barrels in June.”
For Asia, the energy crunch is particularly acute. Japan, which relies heavily on Middle Eastern oil, has been forced to rethink its energy security strategy amid the Hormuz crisis. Meanwhile, China, already grappling with US sanctions pressure on its Iranian oil imports, faces a tightening squeeze as global supply chains adjust.
Sankaran emphasized that the pain is even more severe in the Global South. “The spike in diesel prices is likely to hit countries in the Global South especially hard,” he explained. “The higher energy density of diesel means that it is used to power trucks, buses, and agricultural equipment, making it the most important fuel in poorer countries where individual ownership of automobiles is much less widespread.”
Protests have erupted in several countries. In Syria, demonstrators blocked the Hasaka–Deir ez-Zor highway, burning tires and stopping oil tankers, according to CNN. Muaz Al Abdullah, a Syria analyst at Armed Conflict Location and Event Data (ACLED), said that “fuel availability, rising prices, falling purchasing power, and poor services are all reasons that have accumulated public resentment,” leading to calls for the energy minister's ouster.
The conflict's economic fallout is also reshaping energy strategies across Asia. Decentralized energy solutions are gaining traction as regional grids face mounting strain, while nations like Indonesia are watching fuel costs closely amid domestic economic challenges. The US-Venezuela oil deal has further tightened China's energy security squeeze, adding another layer to the complex geopolitical puzzle.
As the conflict drags on, the economic toll is becoming a central issue for policymakers worldwide. For American consumers, the $121 billion energy bill is a stark reminder of the costs of war. For Asia, the ripple effects are a test of resilience in an interconnected global economy.
