Option D: Anti-inflationary stance
Central Banks often adjust key policy rates to manage economic conditions. When a Central Bank raises interest rates, it typically aims to reduce inflation by making borrowing more expensive, thereby decreasing spending and investment. This action can help cool down an overheating economy and stabilize prices. Conversely, lowering rates can stimulate economic activity by making borrowing cheaper. However, if the graph indicates multiple rate hikes, it suggests a focus on controlling inflation. Thus, the most likely reason for the Central Bank's action, as indicated by the graph, is an _anti-inflationary stance_.
