The European Central Bank (ECB) finds itself at a significant crossroads, grappling with the pressing need to lower interest rates in an attempt to bolster the region's faltering economyHowever, there remains a contentious debate regarding how effective these rate cuts will actually beVarious policymakers within the ECB have differing opinions: some advocate for swift rate reductions to encourage consumer spending and business investment, while others take a more cautious approach, wary that challenges such as high energy costs and a shortage of skilled labor extend beyond the reach of monetary policy alone.

The resolution of this debate will play a crucial role in determining the future trajectory of the ECB's accommodative monetary policyOn a forthcoming Thursday, the ECB is expected to lower the deposit rate by 25 basis points for the fourth timeGiven that inflation seems to be somewhat contained, investors are betting that the dovish stance of the ECB will enable it to guide borrowing costs to levels that could spur economic activity next year.

Central to the debate is the question of whether monetary policy can effectively address the current economic malaise, which some argue is cyclical in nature while others contend it is fundamentally structural

Holger Schmieding, Chief Economist at Berenberg, states, “There is a divergence of opinion among the governing council regarding how much of the current economic softening is cyclical versus structuralThis debate is critical in deciding whether to lower rates below neutralIn reality, the economic situation is a blend of both, meaning the ECB must play its partHowever, rate cuts will not serve as a panacea for economic woes.”

Despite an unexpected acceleration in growth within the Eurozone's twenty nations during the third quarter, recent data indicates a downturnThe Eurozone's industrial powerhouse, Germany, is experiencing a second consecutive year of economic contraction, compounded by political risksMeanwhile, France, the Eurozone's second-largest economy, faces its own set of political and budgetary turbulence.

In this context, the rationale for lowering interest rates appears clear-cut: reduced interest costs for households and a diminished appeal of savings could, in theory, stimulate newly emerging private consumption

Lower borrowing costs could also incentivize business investments, particularly for construction firms, whose profit margins have been under pressure, affecting their capacity for spending.

Gilles Moec, Chief Economist at AXA Group, commented, “Especially in a situation of political vacuum, if the Eurozone’s only entity nearing a united government demonstrates the capability and willingness to act, that would signal confidence.”

Fabio Panetta, the Governor of Italy's central bank, is among the staunchest proponents of quickening monetary policy easing, suggesting the possibility of venturing into an expansionary territoryHe stated last month, “At this stage, we should place greater emphasis on the weakness of the real economy.” He cautioned that stagnant domestic demand could potentially lead inflation below the target of 2 percent.

Conversely, hawkish policymakers such as Isabel Schnabel, an executive board member of the ECB, warn that if the issues being addressed by rate cuts are indeed structural, then such reductions may not produce the intended effects

She points to several underlying problems, including low productivity, diminutive competitiveness, unfavorable demographic trends, and a lack of financial integration.

In an interview in November, Schnabel remarked, “If businesses refrain from investing for reasons outside monetary policy, bringing interest rates below neutral may not stimulate investmentStructural policies are needed to achieve thatIn that scenario, the costs of policy actions could even outweigh the benefits, as they consume the 'precious policy space' necessary to mitigate future shocks.”

The distinction between structural and cyclical issues becomes increasingly muddled, as noted by Olli Rehn, the Governor of the Bank of FinlandHe articulated, “The differences between structural and cyclical have never been clear-cutAlthough Europe’s long-term growth and competitiveness challenges cannot be resolved purely through monetary policy tools, we understand that investment is driven by numerous factors, particularly aggregate demand, which is evidently influenced by financial conditions.” Following recent supply shocks, a relaxed financial environment should help evade “scarring effects” that could inhibit the necessary investments to enhance long-term productivity.

Economic experts surveyed by institutions forecast that borrowing costs will stabilize around 2%, a level that neither constrains nor stimulates economic growth significantly

Expectations, however, hint at more aggressive potential rate cuts, leading to an indicative reduction to approximately 1.75%.

The question of whether the deposit rate, currently at 3.25%, should dip below neutral remains one of the most debated among analystsLike Panetta, François Villeroy de Galhau, Governor of the Bank of France, indicated in November that “if economic growth continues to falter, with inflation risks breaching targets, such a possibility cannot be ruled out.”

Yet, Joachim Nagel, the head of Germany's central bank, expressed his view that he does not currently perceive any significant risk of inflation falling below 2%, thus ruling out the likelihood of adopting expansionary policies for the time being.

This impending debate will unfold over the next few monthsAlthough a majority of economists gravitate towards perspectives emphasizing the cyclical and structural challenges alongside the limitations of monetary policy, there remains concern that the ECB may once again overburden interest rates.

Katharine Neiss, Chief European Economist at PGIM Fixed Income, poignantly remarked, “Rate cuts will not magically resolve all structural dilemmas.” She reiterated, “They need to work hand-in-hand with structural reforms, bolstered by supportive fiscal policies
