China's central bank abruptly strengthened the yuan this week, reversing a brief easing of currency controls despite a surging dollar. The People’s Bank of China (PBOC) set Wednesday’s daily reference rate at 6.9124 yuan per dollar, the strongest since August, signaling efforts to stabilize markets amid Middle East turmoil. This rare move comes after easing a derivatives rule last week, reflecting policymakers’ growing concern over risks from higher oil prices and capital outflows.***

The shift underscores China’s vulnerability to oil shocks, as it imports nearly 80% of Iran’s crude—13% of its total oil supply—via the Strait of Hormuz. With tensions escalating between Iran and Israel, disruptions could spike energy costs, worsening inflation and straining an economy already facing declining foreign investment. Analysts like ING’s Lynn Song warn that a stronger yuan may now be prioritized to offset import-driven inflation, even as the offshore yuan fell 0.9% in three sessions this week.

Global markets are watching broader Asian currency interventions, with Indonesia and India intervening to prop up their currencies, while Japan and South Korea voiced concerns over dollar volatility. The PBOC’s actions align with efforts to elevate the yuan’s global role, though risks persist. “Stabilizing the FX side could blunt equity losses,” noted Credit Agricole’s Xiaojia Zhi, citing the CSI 300 Index’s 2% weekly drop amid dual pressures.

Amid uncertainty, China’s National People’s Congress opens this week, offering a potential confidence boost. Strategists suggest domestic policy focus may overshadow geopolitical risks. While oil prices remain elevated, the PBOC’s decisive yuan support highlights a priority: balancing currency stability with economic resilience in a volatile global landscape.
