Question map
The money multiplier in an economy increases with which one of the following?
Explanation
The correct answer is Option 3: Increase in the banking habit of the people.
The money multiplier represents the maximum amount of broad money the banking system generates with each rupee of the monetary base. It is mathematically expressed as m = 1/r, where 'r' is the reserve ratio.
- Option 3 is correct because an increase in banking habits leads to more deposits. When people deposit more money rather than holding cash, banks have a larger pool of funds to lend out. This cycle of lending and redepositing expands the money supply, thereby increasing the multiplier.
- Options 1 and 2 are incorrect because an increase in CRR or SLR forces banks to keep more liquid assets or cash with the RBI. This reduces the funds available for lending, which decreases the money multiplier.
- Option 4 is incorrect because population growth does not automatically translate into credit creation unless accompanied by financial inclusion and banking activity.
PROVENANCE & STUDY PATTERN
Full viewThis is a conceptual 'Sitter' derived directly from NCERT Class XII Macroeconomics (Chapter 3). It tests the fundamental formula of the Money Multiplier ($m = \frac{1}{CDR + RDR}$). The strategy is simple: master the variables in the formula—if reserves (CRR/SLR) go up, the multiplier goes down; if people deposit more (banking habit), the multiplier goes up.
This question can be broken into the following sub-statements. Tap a statement sentence to jump into its detailed analysis.
- Statement 1: Does an increase in the Cash Reserve Ratio (CRR) in banks increase the money multiplier in an economy?
- Statement 2: Does an increase in the Statutory Liquidity Ratio (SLR) in banks increase the money multiplier in an economy?
- Statement 3: Does an increase in the banking habit (higher propensity of people to deposit cash in banks) increase the money multiplier in an economy?
- Statement 4: Does an increase in the population of a country increase the money multiplier in the economy?
- Explicitly states the inverse relationship between the reserve ratio and the money multiplier.
- Provides the direct conclusion that a higher reserve ratio yields a lower money multiplier.
- Gives the money-multiplier formula showing it is the inverse of the reserve ratio.
- Directly ties the multiplier's size to the reserve requirement (R).
- Explains that a higher reserve requirement reduces funds available for lending.
- States that reduced lending 'shrinks the money multiplier', linking CRR increases to a lower multiplier.
States the money multiplier depends on the currency-deposit ratio and the reserves-deposit ratio (rdr), and notes rdr depends on regulations on CRR and SLR.
A student can combine this with the basic fact that higher CRR raises required reserves (rdr) to infer higher CRR will change the multiplier (likely reduce it).
Defines CRR as the percentage of deposits banks must keep as cash reserves and shows that higher CRR reduces the portion of deposits available for lending.
Using the lending multiplier logic (less loanable funds → fewer deposit creation rounds), a student can infer higher CRR should lower the money multiplier.
Explains central bank quantitative tools include changing the reserve ratio and explicitly links changing the reserve ratio to changes in lending, deposits and hence money supply; poses a numeric example when reserve ratio is increased.
A student could work through the numeric example (e.g., computing multiplier for different reserve ratios) to test whether raising CRR raises or lowers the multiplier.
Notes that reserves can be kept as CRR or SLR and that rdr is the sum of CRR and SLR, tying CRR quantitatively into the reserve-deposit ratio which affects money creation.
A student could treat CRR as a component of rdr and recalc the theoretical multiplier formula (1/(cdr + rdr)) to see how an increase in CRR shifts the multiplier.
Gives the formal definition Money Multiplier = M3/M0 and states the multiplier may be impacted by any change in components of M3 or M0 (e.g., banking habits).
A student can reason that increasing CRR alters reserve money (part of M0 or affects bank lending that determines M3), so computing effects on M3 and M0 would show the direction of multiplier change.
- Explains how the reserve requirement affects lending and the money multiplier directly.
- States that a higher reserve requirement reduces funds available for lending, which shrinks the money multiplier — implying an increase in reserve-like ratios (such as SLR) would lower the multiplier.
- Gives the money-multiplier formula (1 ÷ R) tying the multiplier inversely to the reserve ratio.
- Explicitly states that a higher reserve ratio means a lower money multiplier, reinforcing that raising reserve requirements reduces the multiplier.
- Specifically describes SLR and notes that raising SLR is used to 'suck liquidity' from the market.
- Reduction in available liquidity for banks to lend is consistent with a lower money multiplier when SLR is increased.
States the money multiplier depends on the currency-deposit ratio and the reserves-deposit ratio, and notes that the reserve-deposit ratio depends on RBI regulations including CRR and SLR.
A student can combine this with the standard multiplier formula to infer that raising SLR raises reserve-deposit ratio, which (ceteris paribus) should reduce the multiplier.
Explains SLR is a statutory requirement limiting the amount of deposits banks can use to give loans, acting as a limit to credit creation.
Using the idea that less lendable deposits mean lower deposit expansion via fractional-reserve banking, a student can deduce higher SLR likely reduces the multiplier.
Defines SLR as the fraction of deposits banks must invest in specified liquid assets, clarifying SLR's role as part of reserves.
A student could map this reserve fraction into the reserves-deposit ratio in multiplier formulas to judge the SLR → multiplier relationship.
Clarifies SLR is maintained in safe liquid assets with respect to NDTL and that excess CRR balances count as liquid assets for SLR purposes.
A student can use this to reason about how regulatory changes to SLR change banks' available lending capacity and thus affect the multiplier.
Gives the operational definition of money multiplier (M3/M0) and notes it may be impacted by any change in components of M3 or M0, e.g., banking habits.
By treating SLR as affecting M3 (bank credit) or effective reserves in M0, a student can test whether raising SLR would lower M3 relative to M0 and thus reduce the multiplier.
- Defines money multiplier as Broad Money (M3) divided by Reserve Money (M0) and links multiplier to changes in these components.
- Explicitly states that any step to increase M3 improves the money multiplier and gives 'increase in banking habit' as an example.
- Describes fractional-reserve banking where banks keep only a fraction of deposits as reserves and lend out the rest.
- Shows mechanism by which deposits lead to successive rounds of lending and deposit creation, expanding the money supply.
- Explains that when banks lend, new deposits are created in borrowers' names, increasing total money supply.
- Connects higher deposits with banks to greater potential for money creation under the banking system.
- Identifies the components (currency ratio C and excess reserves ER) that make the multiplier smaller than the simple 1/rr formula.
- Shows the money multiplier depends on reserve ratio, currency holdings and excess reserves — factors unrelated to population in the passage.
- Gives the standard formula linking the money multiplier to the reserve ratio (m = 1 ÷ R).
- Indicates the multiplier is determined by banking reserve behavior (R), not by population in the quoted material.
- Explains how the reserve requirement directly changes the amount banks can lend and thus the money multiplier.
- Reinforces that institutional/banking rules (reserve requirements) drive the multiplier rather than population in the passage.
This MCQ lists 'Increase in the population of the country' alongside other factors asked to affect the money multiplier, and separately includes 'increase in the banking habit of population' as an option — implying population-related behaviour is considered relevant to the multiplier.
A student could treat this as a prompt to distinguish mere population growth from changes in banking behaviour (e.g., higher deposit rates) when assessing multiplier effects.
Reports observed changes in the money multiplier and links at least one decline to banks' large deposits with the central bank under reverse repo — indicating that where deposits are parked (and not lent) matters for the multiplier.
Combine with a hypothesis that population-driven increases in deposits only raise the multiplier if those deposits are intermediated into loans rather than parked with the central bank.
States that higher demographic dividend (i.e., more working-age population) increases national savings and investment — a population change that can affect aggregate savings and hence banking deposits.
Extend by connecting higher population-driven savings to larger bank deposits, then test whether those deposits translate into increased lending and thus a higher money multiplier.
Explains that the value of a (fiscal) multiplier depends on marginal propensities (to import, consume, etc.), illustrating that multipliers generally hinge on behavioural ratios rather than raw size variables.
Use this general rule to argue the money multiplier will depend on behavioural ratios (e.g., currency–deposit ratio, reserve ratios, propensity to hold cash) which a population change only affects if it alters those ratios.
Defines multiplier logic in investment context and emphasizes the role of marginal propensities (MPC/MPS) in determining multiplier magnitude — reinforcing that multipliers are sensitive to propensities.
A student could analogously apply the idea: population growth per se matters only to the extent it changes behavioural parameters (propensity to save/deposit vs. hold cash), thereby affecting the money multiplier.
- [THE VERDICT]: Sitter. This is a foundational concept found in every standard economy text (NCERT, Singh, Singhania). Missing this indicates a gap in core Macroeconomics.
- [THE CONCEPTUAL TRIGGER]: The 'Money Creation' chapter in NCERT Macroeconomics. Specifically, the section explaining how fractional reserve banking turns 'High Powered Money' ($M_0$) into 'Broad Money' ($M_3$).
- [THE HORIZONTAL EXPANSION]: Memorize the determinants: 1) Currency-Deposit Ratio ($CDR$): Inverse relationship (More cash in hand = Lower multiplier). 2) Reserve-Deposit Ratio ($RDR$): Inverse relationship (Higher CRR/SLR = Lower multiplier). 3) $M_3 = M_0 \times m$. 4) Velocity of Money: Distinct from multiplier; refers to frequency of transactions. 5) Digital Payments: Lower demand for physical cash $\to$ Lower $CDR$ $\to$ Higher Multiplier.
- [THE STRATEGIC METACOGNITION]: Do not just memorize definitions. Visualize the flow: You deposit ₹100 $\to$ Bank keeps ₹10 (Reserves) $\to$ Lends ₹90. If you kept that ₹100 under a mattress (Low Banking Habit), the lending cycle never starts. The question simply asked for the 'trigger' of this cycle.
The money multiplier is determined by the currency-deposit ratio and the reserve-deposit ratio; an increase in CRR raises the reserve-deposit ratio.
High-yield for questions on money creation and monetary transmission: knowing how rdr feeds into the multiplier lets aspirants predict how RBI actions change broad money. It links to topics on monetary base, M3/M0, and credit creation, enabling calculation- and analysis-type questions.

The money multiplier is the ratio of broad money to reserve money and rises when broad money (M3) grows relative to reserve money (M0).
High-yield for monetary policy and banking questions: explains how aggregate deposits and central bank reserves interact; links to topics like liquidity, monetary expansion and policy transmission. Mastery enables answering questions on how changes in deposits, reserve ratios, or central bank operations affect money supply.

The 'Currency-Deposit Ratio' (CDR). Since they asked about 'Banking Habit' (which lowers CDR), the next logical question is the impact of a crisis (like a Pandemic or Demonetization) on the multiplier. During a pandemic, people hoard cash (CDR rises) $\to$ Money Multiplier falls. Conversely, widespread UPI adoption lowers cash usage (CDR falls) $\to$ Money Multiplier rises.
Apply the 'Restriction vs. Enabler' Logic. Options A (CRR) and B (SLR) are *restrictions*—they force banks to lock money away. Locking money stops it from multiplying. Option D (Population) is neutral; more people with cash under mattresses adds zero value. Option C (Banking Habit) is the only *enabler*—it moves money from idle (cash) to active (deposits), fueling the lending engine.
GS3 (Inclusive Growth & Digital Economy): 'Banking Habit' is the technical economic justification for schemes like PM Jan Dhan Yojana. Financial Inclusion isn't just welfare; it is a monetary tool to increase the Money Multiplier, thereby allowing the RBI to manage liquidity more effectively with a smaller Monetary Base ($M_0$).
