How do rising oil prices impact East Asia's current account surplus?
Core argument: Saudi Arabia’s $90/barrel breakeven on 7m barrels/day exports means $100 oil generates minimal surplus, limiting petrodollar system reinforcement vs. prior.
The Saudis aren’t going to generate a big surplus to reinforce the postulated petrodollar system with oil at around $100—not when their balance of payments breakeven (on around 7 million barrels a day of exports) is over $90 a barrel. But if the benchmark price of oil converges to around $100 for an extended period of time, a bit of Asia’s massive current account surplus will flow to those oil exporters able to supply the global market while flows through the Strait are limited. For reference, the average price of Brent in 2025 was just under $70 a barrel. A $10 barrel increase in the price of oil raises the import bill of Europe and the oil importers of South and East Asia by about $160 billion. East Asia in aggregate imports around 20 million barrels day, so every $10 a barrel raises East Asia’s import bill by $70-80 billion over the course of a year. But East Asia can afford a big shock. A sustained $50 a barrel shock (oil at $120 a barrel) would reduce East Asia’s current account surplus by $350 billion (more, if counting gas), leaving the combined surplus of Korea, Taiwan, Japan, and China well above $1 trillion.
