Micro and Macro prudential measures: What are they?

This topic has been requested by Kewbie Lau who is community member of LinkedIn community.

To understand the macro prudential and micro prudential measures adopted by the central bank like the Bank of England, let me give you an analogy. For this, let me take you back to your school days and tell you a short story

Imagine you are principal of a school in your current locality. It is a small school with just 5 rooms for each grade. Say, the grades Grade 1 - Grade 5. As a principal, you have an ambition that you want your entire school to excel in Maths, Science and Sports.  For this you have given the targets to your individual class teacher and told them how you would monitor the performance of each class regularly. It is obvious to you that unless and until each class performs, your school will not be able to achieve its ambitions. In other words, the performance of the school is dependent upon each class/grade. Is it clear so far?

Now, the class teacher has to ensure that they are responsible for the performance of their respective class. Each teacher works hard to ensure they ensure the students perform well. To assess the performance, there are regular tests being arranged for each class/grade. The performance reports are shared with the Principal. Principal goes through the details and discusses the performance review with each class teacher and asks them to take corrective actions, as and when required. So, there is a regular performance review.

Principal comes up with the idea of arranging "Surprise" tests for a smaller portion of the curriculum and then checking the performance of each class. As there are "surprise" tests, there is no fixed frequency and ensures that both the teachers and students are on their feet to perform. These surprise tests revealed a bit more detail on the preparation and ensured that everyone is up to date with their preparation. This continued for a year and the performance of school improved best in the entire district and was awarded as best school in the district.

Good story, isn't it?

Let us come back to Micro and Macro prudential measures adopted by a central bank like Bank of England. Drawing the parallel with the above story.  Here the role of Principal is being played by the Central bank and each individual bank is the class teacher. Like the principal of the school, it is the responsibility of the central bank to ensure that each individual bank is performing well.

Micro-prudential and macro-prudential measures are two different approaches used by central banks including the Bank of England, to regulate and oversee the banking sector.

1. Micro-prudential Measures:
    Micro-prudential measures focus on the individual institutions within the financial system, such as banks and other financial institutions. 

• The main goal of micro-prudential regulation is to ensure the safety and soundness of individual financial institutions by assessing their risk management practices, capital adequacy, liquidity, and overall financial health.

• These measures typically involve regulations and supervisory practices that are tailored to specific institutions based on their size, complexity, and risk profile.

• Examples of micro-prudential measures include setting minimum capital requirements, conducting stress tests on individual banks, and enforcing regulations on lending practices.

2. Macro-prudential Measures :
    Macro-prudential measures take a broader view of the entire financial system and aim to address systemic risks that could threaten financial stability. 

• Rather than focusing on individual institutions, macro-prudential policies consider the interconnections and inter-dependencies within the financial system as a whole.

• The objective of macro-prudential regulation is to identify and mitigate systemic risks, such as excessive credit growth, asset bubbles, and inter-connectedness among financial institutions, which could lead to widespread financial instability.

• Examples of macro-prudential measures include setting countercyclical capital buffers, implementing loan-to-value ratios on mortgages to curb excessive lending, and conducting system-wide stress tests to assess the resilience of the financial system to various shocks.

In summary, micro-prudential measures concentrate on the safety and soundness of individual financial institutions, while macro-prudential measures focus on safeguarding the stability of the entire financial system by addressing systemic risks. The Bank of England employs both micro and macro-prudential measures to ensure the stability and resilience of the UK banking system.

Is Scenario analysis applied to both Micro and Macro-prudential measures?

What is Scenario analysis after all? In simple words, it is about  "What to do if this happens?". Everyone practices scenario analysis for every important situation. Few examples are:

1. When you plan your vacation, why do we opt for travel insurance? Perhaps you have thought of scenarios like what if you lose your luggage, you fall ill, your flight gets cancelled at the last minute...etc.. Relatable?

2. You have invited your friend for dinner. Do you prepare only one dish? If not, why? It is because you have thought of certain scenarios.
I mean to imply scenarios can be applied to any situation to prepare you better if the things do not go as planned or if there are risks that can lead to losses. Be it financial, reputation etc..

So yes, scenario analysis can be applied to both micro-prudential and macro-prudential analysis, although the specific focus and scope may vary.

1. Micro-prudential Analysis:

• In micro-prudential analysis, scenario analysis is typically used to assess the potential impact of various risk factors on individual financial institutions. 

• This involves constructing hypothetical scenarios, such as economic downturns, interest rate fluctuations, or sector-specific shocks, and analyzing how these scenarios could affect the financial condition of a specific bank or financial institution.

• Micro-prudential scenario analysis helps regulators and supervisors evaluate the resilience of individual institutions to different adverse conditions and identify potential vulnerabilities in their risk management practices.

2. Macro-prudential Analysis:

• In macro-prudential analysis, scenario analysis is used to assess the resilience of the entire financial system to systemic risks and potential shocks.

• This involves developing scenarios that reflect various macroeconomic and financial market developments, such as recessions, asset price bubbles, or global financial crises, and analyzing how these scenarios could impact the stability of the financial system as a whole.

• Macro-prudential scenario analysis helps policymakers and regulators identify systemic vulnerabilities, design appropriate policy responses, and enhance the resilience of the financial system to systemic risks.

While the underlying principles of scenario analysis remain consistent across micro and macro-prudential analysis, the scale and focus of the analysis differ. Micro-prudential scenario analysis evaluates the risks faced by individual institutions, while macro-prudential scenario analysis assesses systemic risks and their implications for the broader financial system.
