Money & Banking

Money performs four functions:

1. Medium of exchange: accepted for buying/selling goods
2. Store of value: holds purchasing power over time
3. Unit of account: used to compare values (prices)
4. Standard of deferred payment: used for credit/loans

Characteristics of good money: generally accepted, portable, durable, divisible, uniform (all notes of same denomination identical), scarce (limited supply).

Commercial banks: (e.g., HBL, MCB, UBL in Pakistan) — accept deposits, give loans, offer services. They create credit — they lend out more than they hold in deposits. This expands the money supply.

State Bank of Pakistan (SBP): Pakistan's central bank. Functions:

• Issues currency (banknotes and coins)
• Acts as banker to the government
• Regulates and supervises commercial banks
• Implements monetary policy

Monetary policy: Central bank controls money supply and interest rates to achieve economic goals:

• Raise interest rates → borrowing more expensive → less spending → reduces inflation
• Lower interest rates → cheaper borrowing → more spending → stimulates economy

Inflation: General rise in prices. Caused by excess demand (demand-pull) or rising costs (cost-push). Measured by Consumer Price Index (CPI). Pakistan's inflation exceeded 38% in 2023 — among the highest in its history.

Mastery Extension: Money & Banking

This extension turns the lesson into an active study session for Economics (AKU-ECO) on Aga Khan Board. It does not replace the current specification or a teacher's instructions. Use it after reading the main notes, and check the official syllabus linked from the subject page whenever a live rule, paper structure, or assessment detail matters.

Learning Targets

By the end of a focused revision session, you should be able to define the central idea in your own words, connect it to the lesson's supporting concepts, apply it to a new question, and explain why your method or evidence is appropriate. Use the topic description as your boundary: Functions of money, commercial banks, central bank and monetary policy. If an answer wanders outside that boundary, return to the command word and remove material that does not earn a mark.

Use these lesson-specific checkpoints:

• Explain this accurately without copying: Money: medium of exchange, store of value, unit of account, deferred payment.
• Explain this accurately without copying: Commercial banks: accept deposits, give loans, create credit.
• Explain this accurately without copying: State Bank of Pakistan: issues currency, sets interest rates.
• Explain this accurately without copying: Higher interest rates → less borrowing → reduces inflation.

A Reliable Answer Method

Define the relevant term, show the calculation or chain of reasoning, apply it to the organisation or scenario, and finish with a qualified judgement. Do not award yourself analysis marks for repeating the case. State what the evidence changes, who is affected, and why the effect may depend on another condition.

Before writing, spend a few seconds planning. Circle or note the command word, identify the exact knowledge being tested, and decide what evidence, working, example, or quotation is needed. During the answer, make every line do a job. At the end, reread the question and verify that your conclusion follows from the steps you actually showed.

Apply the Pakistan Context Carefully

The lesson's local case is State Bank of Pakistan and the 2023 Inflation Crisis. In 2023, Pakistan's CPI inflation exceeded 38% — the highest in 50 years. The State Bank of Pakistan raised its benchmark interest rate to 22% (one of the highest in the world) to reduce borrowing and cool inflation. Higher interest rates made loans for cars, homes, and businesses more expensive, reducing spending. This is textbook SBP monetary policy — and a direct AKU-EB Economics case study Use this example to make an abstract idea memorable, but do not force it into an exam response when the question supplies a different context. A good application names the relevant feature, explains the connection, and also states where the comparison stops.

Try this three-part application drill:

1. Summarise the local example in one accurate sentence.
2. Identify which key point it demonstrates and quote or calculate the evidence available in the lesson.
3. Change one condition in the scenario and explain how the result, interpretation, or decision might change.

Guided Retrieval and Practice

Build a two-column benefit-and-limitation table, calculate any available measure, and write a conclusion that names the condition that would change your decision. Work without notes first; retrieval is the test. Mark the attempt only after finishing, using the lesson and the explanation rather than memory or confidence.

1. Question lens: Which institution issues currency in Pakistan

   After answering, justify the choice using this check: The State Bank of Pakistan (SBP) has the exclusive authority to issue banknotes and coins in Pakistan

1. Question lens: Raising interest rates is used to:

   After answering, justify the choice using this check: Higher interest rates → more expensive loans → less borrowing and spending → reduces demand → reduces inflation

1. Question lens: Commercial banks create credit by:

   After answering, justify the choice using this check: Banks hold a fraction of deposits as reserves and lend the rest — this multiplies the money supply (credit creation)

For every missed question, keep an error log with four fields: what I chose, why it was tempting, the rule or evidence I missed, and the cue I will notice next time. This turns a wrong answer into a reusable revision asset instead of a score you immediately forget.

Seven-Day Revision Loop

• Day 1 — Understand: read the lesson and reduce each section to one sentence.
• Day 2 — Recall: reproduce the key points with the page closed.
• Day 3 — Apply: complete the local-context drill and one unfamiliar example.
• Day 4 — Practise: answer the inline quiz, showing or saying your reasoning before selecting an option.
• Day 5 — Repair: revisit only the weak steps recorded in your error log.
• Day 6 — Mix: combine this topic with an earlier topic from the same subject so that you must choose the correct method.
• Day 7 — Check: complete a timed response, self-mark conservatively, and plan the next review date.

You are ready to move on when you can explain the topic without the notes, answer the lesson-specific checks with reasons, apply the idea to a fresh context, and identify one common mistake before making it. If one of those checks fails, repeat the relevant stage rather than rereading everything.
