Will a major G20 nation experience a double-digit inflation spike again before 2029?

Will a G20 Nation See Double-Digit Inflation Again?

After the 2021–2023 inflation surge, most G20 nations have stabilized prices. But geopolitical fragmentation, climate shocks, and supply chain vulnerability leave the door open for another sudden inflation spike before 2029.

Reasons a Spike Could Happen

Global supply chains remain fragile. Another energy shock, severe drought, or major conflict could rapidly push inflation back into double digits—especially in emerging G20 economies like Turkey, Argentina, or South Africa.

Reasons It Might Not

Central banks worldwide are now far more aggressive and coordinated in controlling inflation. Many have implemented stronger frameworks for managing commodity volatility.

The prediction essentially weighs whether global stability will hold—or whether the next big shock is already brewing.
