Introduction to Inflation and the Reserve Bank
The Reserve Bank of New Zealand (RBNZ) has revealed that it could have prevented the post-pandemic inflation surge by hiking the Official Cash Rate (OCR) to 6% before the end of 2021. However, this move would have induced a deeper recession than the Global Financial Crisis, with an estimated 120,000 fewer people having jobs and mortgage rates hitting 8%.
Analyzing the Scenario
The RBNZ’s analysis is based on a mechanical model that simulates the effect of different monetary policy settings in the aftermath of 2020. The model shows that keeping annual inflation below 3% would have required the OCR to rise 500 basis points in the first nine months of 2021, reaching 6% two years earlier than the actual 5.5% peak that occurred in May 2023. This would have had a significant impact on the economy, with an output gap of -3.8% and unemployment estimated to have peaked at 6.2%.
The Impact on the Economy
The RBNZ’s scenario analysis suggests that an earlier and more aggressive tightening of monetary policy could have reduced inflation sooner. However, this would have been difficult given the data available at the time and could have conflicted with the Monetary Policy Committee’s (MPC) mandate, which included maintaining maximum sustainable employment. The analysis also shows that a more plausible scenario involving tightening policy two or three months sooner and getting to 5.5% six months earlier would have lowered the inflation peak to 6.4% from 7.3% in 2022 and caused a more moderate recession.
The Challenges of Implementing Monetary Policy
The RBNZ notes that implementing such a drastic monetary policy would have been challenging, given the global monetary policy cycle and market expectations at the time. A rapid and unexpected tightening would have been well out of step with these expectations, potentially constituting a significant shock to financial markets and increasing interest rate and exchange rate volatility. The policy shock would also have tested the resilience of household, corporate, and banking balance sheets, heightening the risk to financial system soundness.
Progress Made by the RBNZ
The RBNZ has made progress in implementing the recommendations made in a monetary policy review published in 2022. Chief Economist Paul Conway notes that the period of high inflation and economic volatility has provided valuable insights into how economic activity, price setting by businesses, and inflation expectations can evolve. The RBNZ has developed a better understanding of supply shocks, neutral interest rates, and fiscal policy instruments, and is monitoring the economy with more high-frequency data.
Conclusion
In conclusion, the RBNZ’s analysis suggests that an earlier and more aggressive tightening of monetary policy could have reduced inflation sooner, but would have had significant economic costs. The RBNZ has made progress in implementing the recommendations made in the monetary policy review, and is well-equipped to navigate future shocks while maintaining price stability. However, the challenges of implementing monetary policy in a rapidly changing economic environment highlight the need for careful consideration and nuanced decision-making by policymakers.
