THE ROLE OF ASSET LIABILITY MANAGEMENT (ALM)

Dear Followers,

The role of ALM is frequently described as ‘a Bank within the Bank.’

Asset Liability Management (ALM) refers to managing the structure of a bank's balance sheet with two key objectives:

• To keep risks within the bank's risk-bearing capacity.
• To generate returns on the capital allocated to banking book risks.

These objectives are set by the bank’s Asset Liability Committee (ALCO) within the treasury division, recognizing that each bank has a unique risk appetite for interest rate risk and liquidity risk in the banking book. The ALM desk manages these risks, balancing the trade-off between risk and profitability based on the bank’s individual strategies and goals.

Banks establish their own balance between risk and profitability within their banking books. To accomplish this, banks typically use two different strategies:

A) "Riding the Yield Curve" strategy and

B) "Immunisation" strategy.

We will explore both of these strategies in detail later in the article.

A question to my followers: What other strategies do you think banks use to balance risk and profitability, and how effective do you find them?

Background:

ALM charges the asset centre (the business unit responsible for providing products like credit cards, mortgages, and commercial loans) with the FTP rate and credits the liability centre (the unit responsible for offering products to clients who invest or deposit funds in the bank) with the same rate. This process transfers financial risks, such as interest rate and funding risks, from the business units to ALM for management, which is why ALM is often referred to as a "bank within the bank." This system forms the foundation of the FTP process, illustrated in the Figure.        

However, it's important to note that certain risks specific to the bank cannot be transferred to the financial market through derivatives or managed by ALM. This can happen due to issues like improper FTP setup (such as incorrect methodologies or curve construction) or the lack of a liquid derivatives market in particular locations or currencies. By its nature, credit risk cannot be transferred to ALM either.

In essence, ALM manages balance sheet risks using financial instruments, though not all such risks fall under its purview. Credit risk, which often consumes the largest portion of capital, is usually overseen by a separate body, such as the Total Bank Management Committee or, in some banks, a Risk Committee. Credit risk is closely tied to the bank's commercial strategy and the products it offers.

This is thoroughly explained in Chapter 1, titled "ALM of the Banking Book," authored by Beata Lubinska, Ph.D in her book “Asset Liability Management Optimisation: A Practitioner's Guide to Balance Sheet Management and Remodelling”. I highly recommend grabbing a copy for practical insights into the field of ALM.

A) Riding the yield curve strategy:

Background: Some banks are willing to take more risk by using the riding the yield curve strategy in a way where they fund fixed-rate assets (like long-term bonds) with floating-rate liabilities (like deposits or loans with interest rates that change over time).

Breaking it down:

1. Fixed-rate assets: These are investments that pay a steady interest rate over time (e.g., a 10-year bond that pays 5% annually). The return is predictable and doesn’t change, even if interest rates in the market change.
2. Floating-rate liabilities: These are debts or obligations that the bank must pay, but the interest rates on them can fluctuate. For example, a loan where the interest rate is tied to a benchmark like LIBOR or SOFR, which changes over time.

The Risk

By funding fixed-rate assets with floating-rate liabilities, banks are taking on the risk that interest rates might rise. Here’s why:

• The bank earns a steady return from the fixed-rate assets.
• But the cost of their floating-rate liabilities might increase if interest rates rise. This could lead to the bank paying more in interest than it’s earning from its fixed-rate investments.

So, while this strategy can increase profits when interest rates are stable or falling, it exposes the bank to the risk of higher costs when rates rise. This is a key risk that ALCO (Asset-Liability Committee) would need to manage carefully.

In simple terms: The bank is betting that interest rates won’t go up significantly. If they stay the same or go down, the strategy works well. But if rates rise, the bank might end up losing money because it's paying more on its floating-rate liabilities while earning a fixed amount from its assets.

B) Immunisation strategy:

Background: The immunisation of interest rate risk keeping the Duration GAP close to zero.

The institution can adjust its level of interest rate exposure by altering the composition of its balance sheet to achieve the desired duration gap for its target position. A larger duration gap increases the institution’s risk exposure, while a smaller gap reduces it. To completely eliminate interest rate risk, an immunisation strategy can be implemented by setting the duration gap to zero.

However, financial institutions aim to maximise profits, which involves accepting a certain level of risk. The desired risk-return trade-off is shaped by the bank's ALCO policy, which varies from one institution to another. Managing interest rate risk involves determining both the direction and size of the gap based on expected interest rate movements.

In simple terms:

An immunisation strategy is used by banks to protect themselves from changes in interest rates. The goal is to match the duration (or sensitivity to interest rates) of their assets and liabilities, so that fluctuations in rates don’t significantly affect the bank’s overall value.

How it works:

• The bank adjusts its assets (like loans or bonds) and liabilities (like deposits or debts) so that any changes in interest rates won’t lead to big gains or losses.
• If interest rates go up or down, the impact on assets is offset by the impact on liabilities, keeping the bank's financial position stable.

This approach focuses more on minimising risk rather than seeking profit from market movements, which makes it different from strategies like riding the yield curve.

In short:

Immunisation is about creating a safety net to protect the bank’s balance sheet from interest rate risks, ensuring long-term financial stability.
