Macroprudential policy

15 important questions on Macroprudential policy

What three pillar do we need for a strong banking union?

  1. Single supervisory Mechanism (Nov 2014). In order to supervise you first need a comprehensive assessment of the banks. (stress testing and asset quality review (AQR))
  2. Single Resolution Mechanism & Fund (2016)
  3. Single Deposit Guarantee Scheme (?)

What were the policies to en too-big to fail banks?

  • Reduce probability of default (1. Basel III, 2. Macro-prudential buffers (additional buffers to protect for cyclical cash flows), 3. stress testing)
  • Reduce the loss give default ( 1. development of recovery & resolution strategies. 2. enabling of bail-in(a bail in forces the borrowers creditors to bear some of the burden by having part of the debt they are owed written off.

What is a bail-in and how does it cover for bank failure? How much should it be?

In a bail in part of the liabilities are transformed to equities (bonds or liabilities above 100k for instance) in case a bank becomes in distress. Thus a bail in forces the borrowers creditors to bear some of the burden by having part of the debt they are owed written off. The current level should be 8 % of total liabilities including equity.

What is macro prudential policy? How does it differ from micro prudential regulation? 1. Policy objective, 2. Goal. 3. Risk characteristic, Correlations across firms, Calibration of prudential controls.

It stipulates the financial stability of the system as a whole.

  1. Policy objective: Limit financial distress system ( micro: individual firms)
  2. Ultimate goal: Avoid output (GDP) costs linked to financial instability ( micro: consumer protection)
  3. Characterisation of risk: (Dependent on collective behaviour; endogenous (micro: independent of individual agents: exogenous)
  4. Correlations and common exposures across firms: important (micro irrelevant)
  5. Calibration of prudential controls: In terms of system wide-risk, top down (micro: in terms of firm risk: bottom up)

What are the the macro prudential instruments for the systemic risk of excessive credit growth & leverage? and trough which transmission channels do they operate?

  1. Counter cyclical capital buffers
  2. Time varying (Leverage ratio, Risk weights)
  3. Loan-to-value / loan-to-income caps


The transmission channel for counter cyclical capital buffers and Time varying leverage and risk ratios that the resilience of banks contribute to curbing excessive (sectoral credit growth). ???

The transmission channel for loan-to-value and loan-to-income is the resilience of borrowers and banks, mitigate pro-cyclicality mortgage credit.???

What are the key instruments and transmission channel of the systemic risk of excessive maturity mismatch?

  1. Stable funding restrictions (Net Stable Funding Ratio (NSFR) and (LTD)
  2. Liquidity charges


The transmission channel is the resilience of funding base to stressed outflows

What is the key instruments and transmission channel of the systemic risk of exposure to concentration?

  • The Key instrument is large exposure restrictions ( by counterparty, sector, geographic)

The transmission channel is resilience to counterparty and concentration sectors

What is the key instruments and transmission channel of the systemic risk of exposure to TBTF?

  • The key instrument is SIFI (systemically important financial institution) capital surcharges

The transmission channel: lower the probability and impact of failure of SIFIs; increased resilience of banks. There is a high loss given default so you want to lower the probability of default

There are a lot of examples or national macropruedential tools. Name 5 examples:

  1. Leverage ratios
  2. mortgage risk weight floors
  3. restrictions on trading activities
  4. systemic risk buffer largest banks
  5. limits for new lending (loan-to-value, loan-to-income
  6. Countercycilical Capital Buffers CCB (1-3%)

Why do banks in the Netherlands have particularly high LTV ratios?

  • Banks in the Netherlands have long save assets (because of the hypotheek garantie stelsel)
  • People have large defined benefit pensions

Why would it be inefficient to encourage people to have both a defined benefit pension and a house?

One could sell his house and use it for his or her pension. Both a house and a defined benefit pension can be seen as savings for later.

Why does debt overhang reduce labour mobility?

If your mortgage is under water (value of mortgage > value house) selling your house would come at a loss. When house prices are low and demand for houses is low it is difficult to sell (and expensive in case your mortgage is underwater). Th prevents people from moving for a new job.

How does the boom-bust cycle impact intergenerational wealth distribution?

When you enter the labor market in a bust income is low, since your receive a raise each year above your starting income your wealth in the end is significantly lower than for someone entering the market in an upswing (boom)

Looking at the credit cycles, would tat call for national or european macro-prudential policies?

On the one end because credit cycles are different european countries, national policies would be better. But on the other one could argue that more and more companies are cross-border firms, which would ask for european regulation.

What are the policy lessons we have learned so far from the crisis?

  1. national discretion needed for different structural risks
  2. Leverage ratio and risk weights: belt and suspender
  3. Avoid household debt problems before they arise (use LTVs)
  4. Excessive mortgages credit is a problem for households and the economy; less so for banks (Use LTV)
  5. Time-varying measures (Like CCB) can build buffers in upturns enhance resilience against downturns.
