Exploring IB Economics RWE’s Through Argentina’s 100% Interest Rate Policy

In IB Economics, some of the most striking real-world examples (RWE’s) emerge when economies face crisis. Argentina’s extreme monetary response—raising interest rates above 100%—offers a vivid example of how governments attempt to fight hyperinflation and currency collapse. This RWE is perfect for linking macroeconomic theory to policy outcomes, particularly in the context of inflation control, monetary policy limits, and trade-offs between growth and price stability.

Argentina’s 100%+ Interest Rate Policy: Monetary Policy to Tame Hyperinflation

In 2023–2024, Argentina’s central bank adopted one of the world’s most extreme interest rate policies—raising the benchmark rate to over 133% in a desperate effort to fight inflation, stabilize the peso, and regain international confidence. This is a clear example of contractionary monetary policy pushed to its most aggressive form.

Background Information

Argentina has battled with chronic inflation for decades, but by 2023, the situation had spiraled into a full-blown crisis. Annual inflation topped 140%, the peso plummeted, and foreign currency reserves dwindled. In response, the Banco Central de la República Argentina (BCRA) hiked interest rates repeatedly, eventually surpassing 100%.

These rate hikes were part of a broader economic overhaul by newly elected libertarian President Javier Milei, who promised shock therapy reforms: cutting government spending, dollarizing the economy, and slashing subsidies.

The primary goals of the interest rate hikes were to:

• Reduce money supply growth

• Support the Argentine peso

• Discourage consumption and credit

• Cool inflation expectations

Economic Theory and Policy Aims

Argentina’s policy is a bold example of tight monetary policy—used to combat demand-pull inflation and restore currency stability. According to Monetarist theory, reducing money supply growth helps bring down inflation. By making borrowing prohibitively expensive, the central bank intended to:

• Reduce consumption and investment (shift AD left)

• Encourage saving (due to high deposit returns)

• Prevent further depreciation of the peso (by making it more attractive to hold)

However, such policies come with severe trade-offs. According to Keynesian analysis, raising interest rates during an economic downturn can worsen unemployment and push the economy deeper into recession.

Evaluation of the Policy

Short-term outcomes were painful:

• GDP shrank and unemployment began to rise

• Access to credit dried up, harming businesses and consumers

• Inflation remained high, driven by cost-push pressures and fiscal uncertainty

However, there were some tentative signs of stabilization:

• The peso temporarily steadied in unofficial markets

• Foreign investor confidence improved slightly due to Milei’s reforms

• Inflation plateaued, though at extremely high levels

Critics argued that without deeper structural reforms—such as fiscal consolidation, export competitiveness, and institutional trust—the rate hikes alone would not be enough. Others saw them as a necessary evil to reset expectations and prevent full hyperinflation.
