Liquidity
Also written Liquidity (three pillars)
The degree of ease with which you can turn an investment back into cash at a fair value — one of the three pillars of investing, alongside safety and return.
In plain language
Liquidity answers one question: if you needed this money on Thursday, could you have it?
The workbook's definition is the careful one — the degree of ease with which you can encash or liquidate your investment at fair value. Both halves matter. Almost anything can be turned into cash quickly if you accept a bad enough price. Liquidity means getting out at a fair value, quickly.
It is the pillar households underestimate, because it costs nothing until the day it matters, and on that day it costs everything.
How it works
Every investment decision is a trade-off between the three pillars of investment: safety, liquidity and return. You do not get all three at their best, and an investment that appears to offer all three is the classic Ponzi-scheme tell.
Rank ordinary household holdings by how fast money comes back at fair value:
| Where the money is | How quickly, at fair value |
|---|---|
| Savings bank account | Same day |
| Liquid or overnight mutual fund | A working day or so |
| Fixed deposit | Same day, usually with a penalty on the interest rate |
| Listed shares, actively traded | Sold on the exchange; proceeds reach the bank a settlement cycle later |
| Five-year tax-saving bank deposit | Not at all — no premature withdrawal or loan is allowed |
| Property | Months, and the price depends on who is looking |
The workbook is explicit that savings in a bank account exist "to maintain liquidity to meet short term or urgent requirements" and are highly liquid, while investments are "comparatively less liquid". That is the whole reason a household holds both.
A worked example
The Nairs hold Rs 9,00,000: Rs 40,000 in the savings account, Rs 3,00,000 in a five-year tax-saving bank deposit, Rs 2,60,000 in equity mutual funds and Rs 3,00,000 in a three-year bank FD.
A hospital admission lands a bill of Rs 2,20,000 payable on discharge.
- The savings account gives Rs 40,000 at once.
- The five-year tax-saving deposit gives nothing. It has a five-year lock-in with no premature withdrawal and no loan allowed. Rs 3,00,000 of their money is legally out of reach.
- The three-year FD can be broken the same day, at a penalty. Say roughly Rs 4,000 of interest given up on a partial withdrawal of Rs 1,80,000 — an annoyance, not a crisis.
- The equity funds could be redeemed, but the market is 14% below where it was in January. Selling to raise Rs 1,80,000 crystallises a loss of about Rs 29,000 that would probably have reversed.
They break the FD. The Rs 4,000 penalty is the price of liquidity, and it is a tenth of what selling the equities would have cost. Had the emergency fund held six months of expenses in the savings account, the price would have been zero.
Why NISM asks about it
Chapter 2 (Key Concepts in personal finance) contrasts savings and investments on liquidity, and Chapter 3 (Financial Planning) names liquidity as one of the three pillars of investment alongside safety and return. Expect a question that asks which pillar a described situation is about, and a question on why an emergency fund is not held in equity. The Chapter 4 fact that a five-year tax-saving deposit permits no premature withdrawal and no loan is examined on its own.
Common exam traps
- Liquidity is not safety. A government bond is extremely safe and may still be hard to sell quickly at a fair price. Gold is highly liquid and its price moves a great deal.
- Liquidity is not return. The most liquid places to keep money pay the least, which is the trade-off.
- A lock-in destroys liquidity completely — the five-year tax-saving deposit is the workbook's own example, and it forbids a loan against the deposit too.
- "Highly liquid" describes savings; "comparatively less liquid" describes investments — that is the exact wording of the workbook's comparison table.
- A thinly traded share is not liquid just because it is listed. Fair value and speed have to hold together.
- Breaking an FD early costs interest, but it is a cost you can calculate in advance. Selling an equity fund in a fall costs an amount you cannot.
