CAIIB ABM Syllabus: Module Overview

CAIIB is conducted by IIBF twice a year, in June and December. The CAIIB examination consists of compulsory papers including Advanced Bank Management (ABM) and Bank Financial Management (BFM), along with one elective paper. ABM is divided into four modules:

Module A, Unit 3: Money Supply and Inflation

What is Money?

Money is anything that performs the following four functions in an economy:

• A Medium of Exchange: Individual goods, services, and physical assets are priced in terms of money and exchanged using money.
• A Measure of Value: Money is used to measure and record the value of goods or services.
• A Store of Value Over Time: Money can be held over a period of time and used to finance future payments.
• The Standard for Deferred Payments: Money serves as an agreed measure of future receipts and payments in contracts.

Money Supply

Money supply refers to the stock of money in circulation in the economy at a given point of time. It is partly exogenous (determined by the Government and RBI) and partly endogenous (determined by the banking system's credit creation).

Money supply in India is measured using four common measures:

Key Definitions

• Currency with Public: Currency in circulation minus cash held by banks.
• Demand Deposits: All liabilities payable on demand, including current deposits, demand liabilities portion of savings bank deposits, margins against Letter of Credit/Bank Guarantees, balance in overdrafts, and fixed deposit amounts payable on demand.
• Time Deposits: Deposits payable otherwise than on demand, including fixed deposits, cash certificates, cumulative and recurring deposits, and the time liabilities portion of savings bank deposits.

The Concept of Inflation

A sustained rise in the general price level of goods and services in an economy over a period of time is known as inflation. It leads to a fall in the purchasing power of money, meaning the same amount of money can buy fewer goods and services over time.

Causes of Inflation

• Demand-Pull Inflation: A rise in general prices caused by increasing aggregate demand for goods and services. When demand exceeds supply, prices are pulled upward.
• Cost-Push Inflation: Inflation caused by substantial increases in the production cost of important goods and services where no other suitable alternative is available. Rising input costs push up prices.

Measuring Inflation: The Formula

Example: If November 2020 Price Index is Y and November 2019 Price Index is Z, then:

Inflation = (Y – Z) × 100 / Z

Price Indices Used in India

India uses four important price indices to measure inflation:

• WPI – Wholesale Price Index
• FII – Food Inflation Index
• CPI – Consumer Price Index
• GDP Deflator

Wholesale Price Index (WPI)

WPI shows the change in price levels of a basket of goods at the wholesale level. It focuses on prices of goods traded between corporations, not retail prices paid by consumers. In India, WPI (Headline Inflation) is the official inflation index used for policy decisions. The base year for WPI has been 2011-12 since April 2017. WPI is announced monthly; indices for the food group and fuel group are announced on a weekly basis.

WPI Components and Weightage

Consumer Price Index (CPI)

CPI, also known as Core Inflation, shows the change in price levels of a basket of goods and services purchased by households. It is the index of the cost of living. There are four measures of CPI in India:

• CPI for Industrial Workers (IW) – broadest coverage
• CPI for Agricultural Labourers (AL)
• CPI for Rural Labourers (RL)
• CPI for Urban Non-Manual Employees (UNME)

CPI is released by the Labour Bureau, Ministry of Labour and Employment, Government of India.

Difference Between WPI and CPI

• Food weighs more in CPI (ranging between 46% in CPI-IW and 69% in CPI-AL) compared to only 27% in WPI. Thus, CPI is more sensitive to changes in food prices.
• WPI measures wholesale prices while CPI measures retail (consumer) prices.
• WPI is the official index for policy decisions in India; CPI is used as the cost-of-living index.

GDP Deflator

The GDP Deflator is a measure of the level of prices of all new final goods and services that are domestically produced in an economy. Unlike WPI and CPI, the GDP Deflator is not based on a fixed basket of goods and services. It changes as the composition of GDP changes, making it a more comprehensive measure of economy-wide price changes.

Frequently Asked Questions

Q1. What is the difference between M1 and M3 money supply?

M1 (Narrow Money) includes currency with the public, demand deposits with the banking system, and other deposits with RBI. M3 (Broad Money) includes all components of M1 plus time deposits with the banking system. M3 is a wider measure and is more commonly used for monetary policy analysis.

Q2. What is demand-pull inflation? Give a banking example.

Demand-pull inflation occurs when aggregate demand in the economy exceeds the available supply of goods and services, causing prices to rise. In a banking context. Excessive credit growth can fuel demand-pull inflation by putting more purchasing power in the hands of consumers and businesses, which is why RBI uses monetary policy tools such as the repo rate to control credit growth.

Q3. Why is WPI considered the official inflation index in India?

WPI has historically been used as the primary inflation measure for policy decisions in India because it covers a large number of commodities at the wholesale level and provides an early signal of price movements before they reach consumers. However, RBI now uses CPI (Consumer Price Index) as the target inflation measure for monetary policy under the inflation targeting framework introduced in 2016.

Q4. What does the GDP Deflator measure?

The GDP Deflator measures the overall price level of all domestically produced goods and services in an economy. Unlike WPI or CPI which use a fixed basket. The GDP Deflator automatically adjusts to reflect changes in the composition of GDP, making it a more comprehensive but less timely measure of inflation.

Q5. How many papers are there in CAIIB and what are they?

CAIIB has three papers: Advanced Bank Management (ABM) and Bank Financial Management (BFM) are compulsory. And the third is an elective chosen from options such as Retail Banking, Risk Management, Central Banking, or others offered by IIBF. For the latest list of electives, visit iibf.org.in.
