The Boundaries Of Debt-Fueled Economic Growth | Dr. Claudio Borio & Joseph Wang

The interplay between monetary policy and fiscal policy is tightly linked and inextricable. These two policies are the key levers of the state when it comes to macroeconomic policy. They back each other up and have privileged access to resources. The balance sheets of the government and the Central Bank are also linked. A high level of debt as a percentage of GDP poses inherent risks, but determining at what level it becomes a problem is difficult and depends on country-specific circumstances. The maturity of debt around the world is a concern due to high levels of private and government debt, which could lead to trouble during refinancing. The financial cycle refers to the self-reinforcing process of credit expansion and asset prices, leading to overstretched balance sheets and eventual bust phases. The "Twilight Zone" between low-inflation and high-inflation regimes is the topic of the video. The most profound aspect of the topic of balance sheet policy (quantitative easing and quantitative tightening) is the impact of these policies on the financial system and the economy. The non-bank financial sector has grown rapidly, but regulation has not kept up, leading to hidden leverage and liquidity mismatches. Basel 3 regulations have effectively constrained credit risk in the banking system, but do not specifically address interest rate risk. Monitoring interest rates and credit quality is important to mitigate risks and maintain sustainable economic growth.

Interplay of Monetary Policy & Fiscal Policy

Key points:

Monetary policy and fiscal policy are closely connected and support each other.
Monetary policy can prevent technical default of the government, while fiscal policy provides state backing for the effectiveness of monetary policy.
The balance sheets of the government and the Central Bank are linked.
The interplay between these policies has varied throughout history, depending on political developments and globalization.
Central bank independence is crucial for maintaining a low inflation regime, but it can be challenged if the fiscal position becomes unsustainable.
Raising interest rates to address fiscal concerns in emerging market economies can worsen the situation due to capital flows.
There are two forms of fiscal dominance: political economy and economic dominance.
Political constraints can hinder the central bank's ability to fulfill its mandate.

Risks Of Large Debt Loads

A high level of debt as a percentage of GDP poses inherent risks, but determining at what level it becomes a problem is difficult and depends on country-specific circumstances. In the United States, higher levels of debt can be sustained due to the dominant role of the dollar and the willingness of other countries to buy government debt. However, high debt makes the economy sensitive to interest rate increases, which can have political and economic consequences. This sensitivity is also seen in the case of private sector debt, where households and firms may experience financial stress. Additionally, there is evidence suggesting that beyond a certain level of debt, economic growth flattens. Overall, the risks of large debt loads vary depending on the type of debt and the specific context.

Maturity Of Debt Around The World

The maturity of debt around the world is a concern due to high levels of private and government debt, which could lead to trouble during refinancing. Key points include:

High levels of global debt pose potential risks during refinancing.
Debt maturities are lengthening, particularly in the US, delaying the impact of higher interest rates.
The concept of a financial cycle, separate from the economic cycle, highlights the connection between increasing debt burdens and the current financial environment.

The Financial Cycle & Central Banks

The financial cycle refers to the self-reinforcing process of credit expansion and asset prices, leading to overstretched balance sheets and eventual bust phases. Central banks play a role in the financial cycle through their monetary policy regime. The reaction function of the central bank, focusing on near-term inflation rather than credit behavior, can impact the financial cycle. Before the mid-1980s, recessions were mainly caused by inflation, but after that, financial booms turning into busts became the main cause. Central banks now have more awareness of the financial cycle and implement reforms to address financial imbalances. The lack of prudential regulation during financial liberalization contributed to the destabilization of the financial system.

"Twilight Zone" Between Low-Inflation and High-Inflation Regimes

The "Twilight Zone" between low-inflation and high-inflation regimes is the topic of the video. Here are the key points discussed:

In a low inflation regime, inflation is largely the result of temporary idiosyncratic price changes.
In a high inflation regime, inflation is driven by common price changes.
Transitions from low to high inflation regimes tend to be self-reinforcing as people start noticing inflation and it becomes a more important factor in their decisions.
Price stability is defined as a condition where inflation does not have a material impact on people's behavior.
Interest rates play a crucial role in determining the level of inflation, with the concept of "rstar" as a measure of neutral interest rates.
Central banks need to be preemptive in addressing the risk of transitioning from a low to high inflation regime.
There is a stronger relationship between monetary aggregates and inflation during high inflation periods.
The behavior of monetary aggregates is more closely related to the common component of price changes during high inflation.
Money growth is positively related to inflation during transitions from low to high inflation.
Looking at the behavior of monetary aggregates can help predict inflation, but more analysis is needed.
Defining money is challenging due to financial sector innovations and offshore dollars.
Central bank balance sheet expansion and changes in the money supply are correlated.
Episodic correlations between money growth and inflation exist, but there is no long-term relationship.
The correlation between money growth and inflation depends on factors such as who the central bank buys assets from.

Balance Sheet Policy (Quantitative Easing and Quantitative Tightening)

The most profound aspect of the topic of balance sheet policy (quantitative easing and quantitative tightening) is the impact of these policies on the financial system and the economy.

Key points include:

Quantitative easing (QE) involves the central bank pushing reserves into the system to stimulate economic growth.
Quantitative tightening (QT) involves the central bank reducing its balance sheet and decreasing reserves to minimize market impact and term premium.
These policies can affect interest rates, bond yields, credit spreads, and equities.
QT can increase the supply of treasuries and impact the liquidity of certain markets.
Regulations implemented after the financial crisis have made the banking system safer but have also led to poorer liquidity in certain markets.
The trade-off between a stronger financial system and the negative effects on markets may not be significant.
Robust regulation is crucial in maintaining stability and preventing large-scale crises in the financial system.
The financial cycle, driven by risk assessment and the desire for wealth accumulation, involves the interaction between credit and property prices.
Prudential regulation for banks is important in maintaining stability and preventing significant impacts on the economy.
There is a need to address the growth of private credit and private equity.
Considering various factors, such as regulatory measures, is important in assessing the impact of balance sheet policies on debt-fueled economic growth.

Risks In Banking & Non-Bank Financial Sector

The non-bank financial sector has grown rapidly, but regulation has not kept up, leading to hidden leverage and liquidity mismatches. Efforts to regulate this sector face challenges due to differing mandates and a lack of recognition of its systemic impact. Further development of regulation is needed to address systemic risks.

Interest Rate Risk & Credit Risk

Interest Rate Risk & Credit Risk Summary:

Basel 3 regulations have effectively constrained credit risk in the banking system, but do not specifically address interest rate risk.
Interest rate risk refers to the risk of a security losing value due to rising interest rates.
Treasuries are considered to have zero risk weight, but this may depend on their duration.
Banks need to manage interest rate risk, but there is debate on whether central banks should intervene.
Historically low and negative interest rates have made interest rate risk more prominent, leading to difficulties for some banks and investment funds.
The potential credit losses from high debt levels and weakening economic activity have yet to be fully realized.
Rising interest rates can lead to financial stress, retrenchment, and possible bankruptcies.
Lengthening maturity of balance sheets and borrowing at fixed rates may pose challenges when refinancing at higher rates.
The response of debtors and creditors to high interest rates is not the same, with debtors cutting spending more than creditors increase theirs.
The close relationship between central banks and government balance sheets is mentioned, with central bank profits going into remittances to the government.
Higher interest rates can negatively impact the borrowing costs of the public sector and the government's fiscal position.
This may lead to an increase in government debt or the need to raise taxes, both of which can negatively impact economic activity.
Monitoring interest rates and credit quality is important to mitigate risks and maintain sustainable economic growth.
