Bank responses: required reserves are not the same as credit withdrawn
Trace balance sheets, desired liquidity and the demand for loans before assigning a mechanical effect.
Exam scope and assessment notes
Sixteen original lessons and 48 explained guided, independent and transfer tasks introduce the listed causes in enquiry 6.1 for 2027–2029. Compare Republican policy, the boom and unequal wealth, urban/rural differences, speculation and valuation, confidence, war and international trade, banking and the Federal Reserve, agriculture, old and new industries, production and oversupply. This is introductory teaching, not full AS or A Level preparation. Twenty-six further lessons and 78 explained tasks introduce enquiry 6.2: financial losses and bankruptcy, regulation demands, unemployment and hours, agriculture and deflation, welfare, family and minority experiences, Hoover’s agricultural, housing, RFC and relief responses, Bonus Marchers, and the 1932 election and developing coalition. Fifteen further lessons and 45 explained tasks begin enquiry 6.3 through the March crisis, advisers and Congress, holiday and emergency banking legislation, selective reopening, an original source-comparison workshop, conservation work, FERA, agricultural adjustment, industrial codes, public works, TVA and securities disclosure. Eighteen further lessons and 54 explained tasks deepen enquiry 6.3 through original banking-separation and temporary-insurance conditions, securities registration and non-approval, the 1934 market framework, distinct HOLC routes and later operational evidence, farm credit, November CWA recruitment and February 1934 reductions, a local tenant case, labour conditions and an original programme-source comparison. Ten further lessons and 30 explained tasks introduce Supreme Court disputes: Schechter’s delegation and commerce grounds, Butler’s majority and Stone’s dissent, the February 1937 draft’s conditions and ceilings, its failure, Gannett’s press argument, Sumners’s Southern Democratic opposition, the Jones & Laughlin industrial case and existing-seat appointments through 1941. A selected administration/publisher comparison uses original paraphrases, not a full authentic source set. Nine further lessons and 27 explained tasks introduce critics from the Left and Right through Thomas, the June 1936 Communist platform, Townsend’s changing pension plans, Long’s dated redistribution appeal, Coughlin’s monetary proposals and antisemitic propaganda, Republican alternatives and Smith’s Liberty League intervention. A selected Smith/Thomas comparison and a dated official election-table exercise distinguish shared opposition, different institutions, audience, votes and influence. These are original introductory case studies, not complete political histories. Enquiry 6.3 remains partial: wider programme implementation and local, racial and gender access and outcomes, deeper organisational and regional histories of opposition, earlier and later political tactics, further Supreme Court rulings and fuller political and legal depth still need teaching and practice. Ten further lessons and 30 explained tasks begin enquiry 6.4 through the January 1935 security initiative, selected original Social Security assistance, benefit and tax provisions, Wagner Act rights and Board procedures, and WPA creation and work rules. A selected proposal/statute comparison uses original paraphrases, not a full authentic source set. Ten further lessons and 30 explained tasks introduce the 1936 election through the electoral result and its denominator, party claims and pledges, Roosevelt’s Philadelphia economic-freedom argument, the September farm–city broadcast, labour mobilisation, Black political agency and Southern resistance, Farley’s organisation, the July postmaster procedures and June relief anti-coercion provisions. A selected Roosevelt/Republican comparison distinguishes shared concern with insecurity from different institutions. Fourteen further lessons and 42 explained tasks introduce selected 1935–1937 mechanisms: the June tax proposals and enacted individual and corporate schedules; NYA creation and student-aid limits; original rural power loans and allocations; conservation plans, payments and tenant safeguards; farm-acquisition and rehabilitation finance; and original low-rent housing access and finance. A selected tax-proposal/electrification-statute comparison distinguishes instruments and evidence of outcomes. Sixteen further lessons and 48 explained tasks introduce the 1937–1938 recession through industrial measures, fiscal cash flows, payroll collection, reserve requirements and bank responses, Treasury gold finance, inventories and prices, employment and hours, uneven business and household effects, the April recovery proposals, June work-relief and public-works authority, and an upturn with continuing weaknesses. A selected Roosevelt/Eccles comparison preserves the latter’s expressly personal standpoint. All three listed recession strands now have introductory teaching; full historical and assessment coverage remains unfinished. Ten further lessons and 30 explained tasks introduce the original 1938 Fair Labor Standards Act and its 1941 Darby validation: commercial coverage, phased wages and overtime, distinct exemptions, child-labour conditions, special certificates, enforcement and stronger applicable state standards. A selected statute/Court comparison distinguishes purpose, constitutional validity and measured outcomes. This is a selected labour-standards introduction, not complete beneficiary, exclusion or government-change coverage. Eleven further lessons and 33 explained tasks introduce family security under the original 1939 Social Security amendments: earlier monthly operation, worker qualification, wives, widows, children and parents, continuing employment exclusions, distinct state assistance, claims and hearings, pooled finance, actual January–June 1940 payment records and startup limits. A selected law/trustees comparison distinguishes legal rights, recorded delivery and unproven household adequacy. This is a selected family-security introduction, not complete beneficiary, exclusion, administrative or economic-recovery coverage. Enquiry 6.4 remains partial: fuller revenue and programme histories, political motives, deeper regional election and coalition histories, reception and causal evidence, fuller patronage and civil-service practice, programme implementation and unequal access and outcomes, deeper fiscal and bank series, industrial and household experiences, and government, recovery and experiences through 1941 still need further teaching and practice. The 1937 proposal is later follow-through within 6.3, not an event of the First 100 Days. Historical depth, wider authentic reading, subject-specialist review, complete source sets, full papers and calibrated marking remain unfinished. Selected source cards are labelled original paraphrases, not quotations or complete authentic documents. Existing 2026 lessons receive no automatic revised-year credit. The Great Crash, the Great Depression and the New Deal, 1920–1941 is an American Paper 2 topic in 2027 and 2029, and the American Paper 1 topic in 2028. Paper 1 Historical sources is 75 minutes and 40 marks: answer both parts of one question using four sources totalling at most 600 words, with at least three written sources and up to one visual. Part (a) compares two sources for 15 marks; part (b) uses all four sources and contextual knowledge for a 25-mark judgement. Paper 2 Outline study is 105 minutes and 60 marks: answer two questions from one section and both parts of each, with a 10-mark causal explanation and a 20-mark argument. These lessons are introductory practice, not a complete assessment programme.

StudyForA teaching brief · Bank responses: required reserves are not the same as credit withdrawn
[1] Original analytical brief. Trace balance sheets, desired liquidity and the demand for loans before assigning a mechanical effect. This is StudyForA teaching prose, not a contemporary document or a historian’s extract. Write before opening the model.
1. What evidence would strengthen a claim that a requirement increase restricted credit?
Compare after trying
A requirement increase can constrain a bank without mechanically destroying the same quantity of reserves or cancelling the same value of loans. The invented example keeps actual reserves at three hundred while required reserves rise and the excess falls. This establishes an accounting distinction, not a representative national response.
The effect depends on initial positions and preferences. A bank with a large cushion may satisfy the new minimum from existing balances, while another may seek additional liquidity or alter its securities and lending. Borrowers’ demand also affects what happens. The Board’s description of unused reserves explains its contemporary rationale but cannot establish that all banks were unaffected.
The 1938 evidence further separates credit availability from composition: the Board described more investment funds, declining loans to trade and industry and offsetting increases in investments. That observation is not a final verdict on the earlier hikes. It does show why a stronger causal explanation needs comparable bank records, timing and alternative influences, rather than treating required balances, excess reserves and customer credit as interchangeable measures.
Why this response fits
- Connect dated evidence to a specific causal or social mechanism.
- Compare timing, measurement, access and plausible alternatives.
- This original analytical model is not a calibrated examination script or Cambridge grade.
Separate three reserve quantities
A bank’s actual reserve balance, the minimum required by the applicable ratio and the excess above that minimum are different quantities. A higher required ratio can reduce the calculated excess even if the actual balance has not changed. The Board’s contemporary explanation stressed that many banks held unused reserves. That observation helps identify a possible way to meet the higher minimum; it does not establish that every bank had the same position or wished to hold no additional cushion.
Work through an invented balance sheet
Assume a central reserve city member bank has one thousand dollars of qualifying net demand deposits, no relevant time deposits and an actual reserve balance of three hundred dollars. At thirteen percent its required balance is 130 and the excess 170. At twenty-six percent the requirement is 260 and the excess forty. Actual reserves remain three hundred in the example. The calculation changes a classification of the balance; it does not itself remove 130 dollars from reserves or force a particular customer’s loan to be cancelled.
Ask how a bank might respond
A bank might use existing excess balances, alter correspondent balances, adjust securities, seek funds or change lending, depending on its constraints and preferences. If it wants to rebuild an additional liquidity cushion, the effect may differ from a case in which it accepts the smaller excess. Borrowers’ willingness and ability to take loans also matter. These are mechanisms to investigate through dated balance sheets and applications, not a claim that one invented example describes the entire banking system.
Test credit composition as well as its total
The report for 1938 describes more funds available for investment after reserve changes and gold movements, but also a decline over the year in bank loans to trade and industry alongside an offsetting rise in investments. Total bank credit therefore changed little in that account. Easier reserve availability was not synonymous with an equal increase in commercial lending. This later observation does not by itself settle the effect of the earlier hikes; it shows why lending, securities and reserves need separate evidence.

Worked example
How do required and excess reserves change in the invented bank?
Show the worked solution
- Calculate requirements of 130 and 260.
- Subtract each from three hundred to obtain excesses of 170 and forty.
- Distinguish the reclassification from a loan transaction.
Answer The required amount rises by 130 and the excess falls by 130, while actual reserves remain three hundred. The example does not record a loan cancellation or prove that every bank could or chose to respond in the same way.

Guided: How do required and excess reserves change in the invented bank?
Give me a hint
Keep the actual three-hundred-dollar balance fixed.
Compare my reasoning
- Calculate requirements of 130 and 260.
- Subtract each from three hundred to obtain excesses of 170 and forty.
- Distinguish the reclassification from a loan transaction.
The required amount rises by 130 and the excess falls by 130, while actual reserves remain three hundred. The example does not record a loan cancellation or prove that every bank could or chose to respond in the same way.
Look for these in your work
- Uses the relevant dated evidence
- Explains the mechanism and the specific limit
Independent: Does more money available to banks prove that business lending increased by the same amount?
Give me a hint
Compare reserve availability with portfolio composition and borrowers’ demand.
Compare my reasoning
- Separate reserves, loans and securities.
- Read the Board’s account of 1938 loans and investments.
- Seek comparable dates and actual transactions.
No. The Board reported falling loans to trade and industry and rising investments during 1938, despite greater funds available. The categories and timing matter; a change in reserve availability cannot be treated as an identical observed change in business borrowing.
Look for these in your work
- Uses the relevant dated evidence
- Explains the mechanism and the specific limit
Transfer: What evidence would strengthen a claim that a requirement increase restricted credit?
Give me a hint
Look for differing exposure and actual adjustment.
Compare my reasoning
- Compare banks’ initial excess and desired liquidity.
- Trace lending, securities and funding responses after the change.
- Compare credit demand and other policies at the same time.
Use bank-level and aggregate records to test the proposed mechanism, including institutions with different initial cushions. A statutory minimum and an invented balance-sheet calculation do not reveal the national response or isolate it from demand, Treasury policy and other influences.
Look for these in your work
- Uses the relevant dated evidence
- Explains the mechanism and the specific limit
Common mistakes
- Treating calculated excess reserves as an amount physically removed from a bank
- Equating easier reserve conditions with an identical rise in commercial loans
What can you explain now?
Which explanation best fits this lesson?
Compare with the explanation
Distinguish actual, required and excess reserves from subsequent portfolio decisions
A higher minimum can absorb part of an existing excess without changing the actual reserve balance. Actual credit responses depend on balance sheets, preferences, demand and other policies.
