L'outil de la Banque de réserve est-il adapté à son but ?

The Reserve Bank of New Zealand's latest rate hike has sparked heated debate among economists and policymakers, raising questions about the effectiveness of its current inflation-targeting framework. In June, the Monetary Policy Committee (MPC) voted to raise the official cash rate to 2.5%, marking the first increase in three years. This decision followed a closely divided meeting in May, during which the committee was evenly split before Governor Anna Breman cast the deciding vote to maintain the status quo. The move has drawn sharp criticism from some economic analysts, who argue that the timing and rationale behind the rate increase fail to account for broader economic challenges facing vulnerable groups, particularly young people and those in precarious employment. The rate hike came amid persistent concerns about inflation, which remains above the 2% target set by the Reserve Bank. While the central bank maintains that its primary goal is to stabilize prices, critics contend that the current approach, relying heavily on interest rate adjustments, has led to unintended consequences. These include rising unemployment, especially among younger workers, and growing inequality. According to data cited by Bernard Hickey, a prominent commentator and writer for The Spinoff, youth unemployment in certain regions exceeds 20%, while overall unemployment stands at 5.4%. Hickey argues that these figures underscore the limitations of the Reserve Bank’s traditional tools, which prioritize inflation control over broader social and economic stability. The Reserve Bank’s inflation-targeting regime, established under the Reserve Bank Act of 1989, has long been praised for its commitment to monetary independence. This framework, shaped by former finance minister Roger Douglas and supported by economist Ruth Richardson, aimed to insulate monetary policy from political pressures. However, Hickey suggests that this model has created a system where the burden of managing inflation falls disproportionately on specific segments of society. He points to the impact of historically low interest rates and restrictive housing policies as factors contributing to wealth gaps, arguing that the current system has allowed certain groups to benefit while others, particularly those without substantial assets, have been left behind. Hickey’s critique extends beyond economic theory into the realm of public policy. He calls for a fundamental overhaul of the legal structures governing the Reserve Bank and the Public Finance Act, suggesting that responsibility for achieving low inflation should be shifted to the government. His argument hinges on the premise that governments possess greater flexibility and resources to address inflation through measures such as fiscal stimulus, regulatory reforms, and targeted investments in education and infrastructure. By decentralizing inflation management, Hickey believes, the focus would shift toward equitable outcomes rather than solely price stability. Supporters of the current system, including members of the MPC, emphasize the necessity of maintaining inflation targets to ensure long-term economic health. Governor Breman, in particular, defended the rate increase, stating that it would eventually lead to stronger growth and a healthier labor market. She acknowledged the immediate costs associated with tightening monetary policy but maintained that the benefits would materialize over time. Other economists, such as Shamubeel Eaqub of Simplicity and Jarrod Kerr of KiwiBank, have expressed similar views, advocating for continued vigilance against inflation even as the economy faces structural challenges. As the debate continues, the Reserve Bank faces mounting pressure to reconsider its approach. With public dissatisfaction growing and calls for reform intensifying, the institution must navigate a complex landscape of competing priorities. Whether it will adapt its strategy in response to these demands remains uncertain, but one thing is clear: the conversation around the role and responsibilities of the central bank is far from over.
