海外之声 | 欧央行：货币政策是否被财政政策所支配？

导读

本文讨论了货币政策与财政政策之间的相互作用。近年来欧元区面临新冠疫情和俄乌冲突等重大冲击，各国通胀率急剧上升，欧洲央行将利率提高到了史无前例的高度。

与此同时，各国政府为应对这些危机采取了一系列的支持措施，在初见成效的同时也使得公共债务增加。尽管面临这些挑战，欧洲中央银行执行董事会成员施纳贝尔仍认为欧洲央行坚持了其稳定物价的使命，体现了货币主导而非财政主导，并指出，欧洲央行果断加息和缩减资产负债表即是证明。

此外，施纳贝尔谈到了人们对财政主导地位的担忧，指出虽然政府债务高企，但欧洲央行的行动防止了市场分化，维持了人们对货币政策的信心。文章强调了为确保货币政策平稳传导和防止破坏稳定的利率螺旋式上升而引入的“传导保护工具”（Transmission Protection Instrument，TPI）。

展望未来，施纳贝尔强调需要制定面向未来的财政政策，在整顿和必要投资之间取得平衡。她警告说，高债务水平以及人口老龄化、国防、绿色和数字化转型等问题所需的大量公共开支可能会对财政政策构成挑战，结构改革对于促进增长和提高生产力至关重要。

演讲最后重申，货币政策并未被财政政策所主导，欧洲央行对通胀的有力回应和对通胀预期的维持就是例证。她呼吁继续执行财政纪律，以支持欧洲央行的独立性并确保经济的长期稳定。

Is monetary policy dominated by fiscal policy?

Speech by Isabel Schnabel, Member of the Executive Board of the ECB, at a conference organised by Stiftung Geld und Währung on 25 years of the euro – Perspectives for monetary and fiscal policy in an unstable world, at a panel on “Inflation and public budget. Is monetary policy dominated by fiscal policy?”

June 7，2024

In the past four years, the euro area has faced several severe shocks that caused a fundamental shift in the macroeconomic environment.

The long period of very low inflation and low interest rates ended abruptly with the pandemic and Russia’s invasion of Ukraine. In response to the sharp increase in inflation, the ECB hiked interest rates at an unprecedented scale, which markedly increased funding costs for governments, households and firms.

Governments reacted to the pandemic and the war with wide-ranging support measures that were aimed at cushioning their negative impact on income, employment and growth. This led to a significant increase in government debt as a share of gross domestic product, which was softened by the rise in inflation.

Today’s public debt ratio of 90% in the euro area remains close to its high reached during the European debt crisis, by far exceeding the ceiling of 60% set out in the Maastricht Treaty, while there are still considerable differences between Member States.

Fiscal measures played a key role in overcoming the crises. However, the new interest rate environment means that the high debt levels, in particular in highly indebted countries, will result in a considerably higher interest burden in the coming years.

The question therefore arises of whether monetary policy’s ability to act -and therefore its independence -is being constrained by fiscal policy.

This is called fiscal dominance.

My key message is that over the past few years the ECB has pursued its price stability target with great determination, providing credible evidence of monetary dominance.

At the same time, it managed to prevent fragmentation in the euro area, without undermining the disciplinary effect of financial markets. In future, it will mostly be up to fiscal policy to protect central bank independence by advancing fiscal consolidation in line with the new European fiscal rules while not neglecting investments urgently needed to meet future challenges.

Determined monetary policy action disproves fiscal dominance

The determined monetary policy response to the steepest rise in inflation in the history of the euro area convincingly demonstrates that the ECB has by no means deviated from its price stability mandate as predicted by the fiscal dominance theory.

Within a short period of 14 months the ECB raised interest rates, sometimes in big increments, by a total of 4.5 percentage points. It also began to swiftly reduce its balance sheet, mostly by phasing out targeted longer-term refinancing operations (TLTROs) as well as by ending net asset purchases and then reinvestments under the asset purchase programmes.

Critics may argue that the monetary policy response was too hesitant at first. It was not until 12 months after inflation exceeded our 2% target that interest rates were raised for the first time, in July 2022.

However, two facts are worth bearing in mind here.

First, the monetary policy turnaround started as early as December 2021, with the announcement of the end of net purchases under the pandemic emergency purchase programme (PEPP).So financing conditions started to tighten well before the first interest rate hike.

Second, the hesitation to act needs to be seen in the context of a decade of very low inflation and heightened uncertainty due to reoccurring waves of the pandemic.

Central banks only gradually became convinced that the repeated errors in forecasting inflation suggested a sustained increase in inflation that warranted a strong monetary policy response.

The most important evidence of the ECB’s credibility can be found in the development of longer-term inflation expectations.

At first, the ECB welcomed the increase in inflation expectations towards its inflation target of 2%. However, inflation expectations soon began to overshoot that target, with both market- and survey-based indicators pointing to an increasing risk of deanchoring. For a while, a significant part of respondents were expecting medium-term inflation rates well above the inflation target.

In the meantime, however, expectations have returned to the vicinity of our medium-term inflation target of 2%. The broad stability of long-term inflation expectations disproves the theory of fiscal dominance. It rather suggests that our monetary policy response has strengthened the confidence households, firms and market participants have in the ECB’s commitment to bring inflation sustainably back to our 2% target.

This was a remarkable success for monetary policy, which contributed to our decision yesterday to lower interest rates by 25 basis points. However, as the future inflation outlook remains uncertain, we cannot pre-commit to a particular rate path.

Bond spreads reflect fundamental factors and risk appetite

The sharp increase in the ECB’s interest rates did not trigger a sustained rise in sovereign bond spreads between Member States. Some observers have interpreted this as a sign of fiscal dominance. They claim that the ECB may be keeping risk premia artificially low by investing in sovereign bonds of selected highly indebted countries, thus undermining fiscal discipline. In the medium term, so the argument goes, this could lead to fiscal dominance and higher inflation.

Yet, it needs to be borne in mind that when interest rates started rising, sovereign bond yields rose significantly for all Member States. Today, average yields on ten-year sovereign bonds in the euro area are around three percentage points higher than just before the pandemic. This significant increase provides a clear incentive for all Member States to reduce their debt levels.

The yield increases were largely due to rising interest rate expectations and term premia, while credit risk premia -measured here by credit default swaps -remained remarkably stable or even fell slightly.

There are various factors that can help explain recent developments in credit risk premia.

The most important one is the comparably benign economic development of more highly indebted countries. While economic growth is particularly depressed in the “safe haven” of Germany, the countries that were in crisis before have fared much better since.

Higher long-term growth, in turn, supports debt sustainability. Ultimately, the level of risk premia is dependent on the differential between interest rates and growth (r-g).

The positive economic development in parts of the euro area is, first and foremost, the result of years of effort invested into strengthening resilience and economic dynamism after the sovereign debt crisis.

The European fiscal measures in response to the pandemic -in particular the Next Generation EU (NGEU) programme -are likely to have played an important role as well.

First, countries with higher debt levels benefit from NGEU funds to a larger extent, which should support euro area convergence in the long run by increasing potential growth in these countries.

Second, NGEU was a strong vote of confidence in Europe’s ability to act. NGEU is a symbol of a Europe capable of handling crises decisively together. It likely has sustainably lowered the risk of fragmentation in the euro area -contributing to lower bond spreads.

Second, the future debt burden depends on average yields, not just current interest rates.

Before the pandemic, many governments locked in low interest rates by issuing long-term bonds. The average bond maturity of euro area countries rose from around six to eight years. Therefore, a large part of outstanding debt still benefits from low interest rates.

Finally, the third factor behind low risk premia is the current high risk appetite displayed by investors in global financial markets.

The risk premia for European corporate bonds have fallen sharply since the beginning of monetary policy tightening, while equity markets are booming, likewise largely due to the falling risk premia.

The resilience of asset prices can probably be explained in part by the fact that excess liquidity remains high. The ECB and other central banks have adopted a gradual and cautious approach to balance sheet reduction as going too fast could cause disturbances in financial markets.

Such constraints, which may restrict the central bank’s ability to act, need to be carefully examined as part of the proportionality assessment when asset purchases are being considered as a monetary policy instrument.

That said, the gradual and predictable approach to balance sheet reduction contributed to a smooth exit that also benefitted from favourable market conditions.

Recently, the record volume of government bond issuance has met with strong demand in financial markets. The bid-to-cover ratios, a measure used to gauge demand relative to supply in bond markets, have consistently increased since the start of 2023.

Given the anticipated peak in interest rates, investors were keen to lock in the attractive yields over the long term. As the Eurosystem reduced its presence in sovereign and corporate bond markets, notably foreign investors returned as yields in the euro area had become considerably more attractive.

In some Member States, domestic households also played a significant role as purchasers of government bonds.

The ECB’s withdrawal from asset purchases was thus supported by favourable macroeconomic and global conditions.

Smooth transmission of monetary policy supports price stability

In June 2022, however, when the ECB’s Governing Council announced its intention to increase interest rates for the first time at its next monetary policy meeting, such a smooth interest rate cycle could not have been foreseen. Just shortly after the monetary policy meeting, sharp movements in bond markets emerged.

This dynamic was triggered by concerns that inflation would be more persistent than expected. These concerns were prompted by poor inflation data from the United States, which led to a sharp rise in US yields - for example of around 70 basis points for the two-year US Treasury within one week. Market turbulence was hence by no means confined to the euro area.

However, the architecture of the euro area carries a particular risk of self-reinforcing interest rate dynamics. As investors can quickly transfer funds from one part of the monetary union to another part that is regarded as a safe haven, without incurring any currency risk, the combination of national fiscal policy and European monetary policy can - in times of great uncertainty - result in sudden interest rate spirals in bond markets.

Past experience shows that such interest rate spirals can make single monetary policy impossible. If sovereign bond yields of different Member States diverge abruptly, a smooth transmission of monetary policy across the whole euro area can no longer be ensured.

In the conditions prevailing at the time, the necessary interest rate steps could therefore have led to disproportionately higher interest rate adjustments in parts of the euro area.

In response to this market turbulence, the ECB announced its Transmission Protection Instrument (TPI) in July 2022. The TPI aims to ensure the smooth transmission of monetary policy by countering disorderly market dynamics, unwarranted by fundamentals.

The TPI sets clear conditions for the purchase of a Member State’s bonds. These conditions are intended to ensure that the instrument is only used in countries that pursue sound and sustainable fiscal and macroeconomic policies.

The TPI is hence not simply a continuation of the flexibility under the PEPP. During the pandemic the latter allowed for conducting asset purchases flexibly over time, across asset classes and among jurisdictions.

This flexibility was used temporarily at the outset of the pandemic and at the start of the hiking cycle to counteract disorderly movements in bond prices. However, deviations from the ECB’s capital key remained limited.

Speculation that the ECB has permanently skewedits asset purchases in certain directions is unfounded. Temporary fluctuations in the capital key often occurred for technical reasons and, as shown by the examples of Italy and France, added up to zero over the entire calendar year 2023.

The TPI, by contrast, is a new instrument in the ECB’s toolkit. Its targeted orientation and conditionality ensure the smooth transmission of monetary policy, even in times of heightened uncertainty and volatility, thus enabling monetary policy to pursue its key task of maintaining price stability.

By announcing possible interventions or, if necessary, by carrying out targeted, temporary interventions, the central bank can quickly restore confidence and prevent destabilising interest rate spirals, which might otherwise drag the euro area into a severe crisis.

In this respect, the TPI is an expression of monetary rather than fiscal dominance. Indeed, the announcement of the TPI is likely to have been an essential precondition for the ECB to be able to increase rates to such a large extent and so avoid a deanchoring of inflation expectations and ensure price stability.

Under the TPI, the ECB cannot counter persistent tensions that are due to country fundamentals. It could only do so in combination with a macroeconomic adjustment programme under the Outright Monetary Transactions (OMT) programme.

These precautions ensure that market discipline is preserved. Within the TPI there is no interest rate level that is targeted; this level remains fully determined in the market, with the substantial differences in sovereign bond yields across euro area countries reflecting different fundamentals. The TPI can only be used to tackle disorderly dynamics that temporarily prevent price determination in the market. These conditions preserve the incentive for sound fiscal policies.

Fiscal discipline and structural reforms are the best protection against fiscal dominance

The best protection against fiscal dominance is therefore a future-proof fiscal policy. This is precisely why the European Treaties provide for a fiscal framework that permanently guarantees the central bank’s independence.

The challenges for fiscal policy are likely to increase in future.

As long as the yields on newly issued sovereign bonds surpass the average yields on outstanding debt, the interest burden will increase. For example, a prolonged period of high interest rates will gradually affect the interest-growth differential (r-g), which, in addition to the evolution of government primary balances, determines the development of public debt ratios (Slide 13, left-hand side).

Whether (r-g) will become a burden in the medium term will largely depend on how fiscal policy will tackle the multiple structural challenges facing our economies.

An ageing society, the need for higher defence spending in view of the changed geopolitical situation, as well as the green and digital transformations require substantial additional public spending.

The huge investment required to meet all of these challenges suggests that the era of very low interest rates is likely to be over, also in the medium to long term.

This calls for policies that, on the one hand, take advantage of times of favourable cyclical developments to consolidate public finances but, on the other, prioritise necessary investment and structural reforms.

The new European fiscal framework provides for precisely such a balance.

Current projections give cause for concern, however. Structural primary balances in 2024 and 2025 are expected to remain well below pre-pandemic levels, thereby putting upward pressure on government debt.

One reason for this is that some government support measures taken during the crisis years were not fully phased out.

The lack of fiscal consolidation, despite high debt levels, may impede monetary policy and heighten the risk of fiscal dominance.

Measures to strengthen long-term growth are equally important.

Europe plays a central role here. It still offers considerable unexploited growth potential. Deeper integration of the internal market for services could boost productivity, as could the urgently needed progress on the banking union and the capital markets union.

NGEU can accompany this process. However, it’s not yet certain whether this programme can meet the high expectations. A successful evaluation of the programme is likely to determine whether a follow-up programme is eventually conceivable at European level.

At the same time, structural reforms to improve labour mobility, increase labour market participation, promote lifelong education and exploit the potential of new technologies such as artificial intelligence are essential.

It is precisely in the area of information and communication technology that many firms domiciled in the euro area are lagging behind global developments.

Reforms that increase potential output would not only ease debt reduction but would also reduce inflation pressures in the long run. This is all the more important at a time of looming de-globalisation and climate change, when the European economy is likely to be more exposed to supply-side shocks.

Conclusion

This brings me to the conclusion that monetary policy was not dominated by fiscal policy in recent years and that monetary policy’s ability to act was ensured.

The determined monetary policy response to the sharp increase in inflation and the anchoring of inflation expectations despite inflation rates in double digits show that monetary policy has unwaveringly pursued its objective of price stability and that confidence in monetary policy has successfully been preserved.

The TPI made a decisive contribution by ensuring a smooth transmission and was thus a prerequisite for being able to resolutely tackle the inflation problem. Self-reinforcing interest rate spirals run counter to the objective of price stability. The design of the programme ensures that the disciplining effect of financial markets is not undermined.

In the coming years, a future-proof fiscal policy will be a prerequisite for safeguarding the independence of monetary policy. Fiscal consolidation in line with the new European fiscal rules, while prioritising investment in the future, is essential to safeguard long-term growth and price stability.

Thank you for your attention.
