Current Affairs for 12 October 2026

Nobel Prize in Economics 2026: Robert E. Hall and Michael Woodford

Why in news?

• The 2026 Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel is scheduled to be announced on 12 October 2026.
• The award is goven to Robert E. Hall (Stanford University) and Michael Woodford (Columbia University).

Key Facts

Who Is Robert E. Hall?

• American economist associated with Stanford University.
• Known for research in macroeconomics, consumption, unemployment and business cycles.
• His research examines how households and labour markets respond to changing economic conditions.
• He has also studied prolonged economic downturns and the difficulties of restoring employment. 

Major Contributions of Robert E. Hall

• Consumption and the Permanent Income Hypothesis
  • Hall's research helped explain why household spending depends not only on current income but also on expectations about future income.
  • Under particular assumptions, changes in consumption should be difficult to predict using information already available to households.
  • This is associated with his influential 1978 research on the random walk hypothesis of consumption. 
  • Example: If a person expects a salary increase next year, they may adjust their spending decisions today. An unexpected job loss, however, can produce a much larger change in spending.
• Unemployment and Labour Market Dynamics
  • Hall has studied how workers find jobs, how firms recruit employees and why unemployment can remain high during economic downturns.
  • His work includes research on unemployment when nominal interest rates approach their effective lower bound.
• Business Cycles and Economic Recessions: His research also examines why economies experience persistent slowdowns and why recovery may be difficult even after financial conditions improve.

Who Is Michael Woodford?

• American economist associated with Columbia University.
• Known for influential contributions to modern monetary economics.
• His work examines how central-bank policies influence inflation, output and expectations.
• His research has helped develop the theoretical foundations of modern New Keynesian monetary policy. 

  Major Contributions of Michael Woodford

• New Keynesian Macroeconomics: New Keynesian models explain how decisions by households and firms interact with price and wage rigidities. Prices and wages do not always adjust immediately when economic conditions change. Therefore, monetary policy can influence real economic activity, particularly in the short run.
• Forward Guidance: Forward guidance refers to communication by a central bank about the expected future direction of monetary policy. For example, a central bank may signal that interest rates are likely to remain low for some time, subject to economic conditions. Such communication can influence borrowing, investment and spending decisions even before the central bank changes its policy rate. Woodford's research explores the importance and limitations of these expectation-based policy effects.
• Interest and Prices: Woodford's influential book Interest and Prices: Foundations of a Theory of Monetary Policy (2003) provides a systematic framework for analysing monetary policy in modern economies. It connects interest-rate decisions, inflation expectations and economic stabilisation.

What Is Forward Guidance?

• Forward guidance is a monetary-policy communication strategy through which a central bank provides information about its likely future policy stance.
• Suppose inflation is under control but economic growth is weak. A central bank may indicate that interest rates could remain relatively low until economic conditions improve.
• Businesses and households may respond to this information when making investment, borrowing and spending decisions.
• However, forward guidance is not a guarantee. Its effectiveness depends on credibility, public understanding, economic conditions and whether the guidance is conditional or unconditional.

Relevance for India's Monetary Policy

• Inflation Targeting: India's monetary policy framework uses the Consumer Price Index (CPI) as its inflation measure. The RBI's Monetary Policy Committee makes policy-rate decisions within the applicable inflation-targeting framework.
• Monetary Policy Transmission: Changes in the repo rate can influence banks' lending rates, deposit rates, borrowing costs and economic activity. However, the transmission of monetary policy is neither immediate nor uniform.
• Expectations and Communication: The RBI's policy statements, inflation forecasts and explanations can influence how businesses and households assess future economic conditions.
• Employment and Economic Growth: Understanding household consumption, investment decisions and labour-market behaviour can help policymakers analyse economic slowdowns.

What is the Nobel Prize in Economic Sciences?

• The Nobel Prize in Economic Sciences is an international award recognising research that improves our understanding of how economies function.
• Economics studies how individuals, businesses and governments make decisions about limited resources.
• The prize recognises contributions that improve economic knowledge, research methods or policy understanding.

Why is the Economics Prize different from other Nobel Prizes?

• Alfred Nobel's will of 1895 established prizes in five fields: Physics, Chemistry, Physiology or Medicine, Literature and Peace. Economics was not among the original five categories.
• In 1968, Sveriges Riksbank established the Economics Prize to commemorate its 300th anniversary.
• The first prize was awarded in 1969.
• Although commonly called the Nobel Prize in Economics, its official name remains the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel.
• It follows Nobel-related award traditions and is presented during the annual Nobel ceremonies. 

Who awards the Nobel Prize in Economics?

• The Royal Swedish Academy of Sciences selects the laureates. It is also responsible for awarding the Nobel Prizes in Physics and Chemistry.
• The Academy evaluates economic research through a specialised committee and expert assessments.
• The Economics Prize is not awarded by the Swedish Academy, which selects the Nobel Literature laureate.

How is the winner selected?

• Invitation to qualified nominators
• Submission of nominations
• Review by Economic Sciences Prize Committee
• Expert evaluation of research
• Royal Swedish Academy's final decision

Previous Nobel Prize in Economics Winners

India's Connection with the Nobel Prize in Economics

RBI's New CRR Rule 2026

Why in news?

On 9 October 2026, the Reserve Bank of India (RBI) announced an increase in the minimum daily Cash Reserve Ratio (CRR) maintenance requirement from 90% to 99%.

Key Facts

What is CRR (Cash Reserve Ratio)?

• The percentage of a bank's Net Demand and Time Liabilities that must be maintained as cash balances with the RBI. 
• Banks cannot freely use their mandatory CRR balances for lending or investment. RBI does not pay interest on mandatory CRR balances.
• By adjusting CRR requirements, RBI can influence the amount of money available in the banking system.

Eg. Suppose a bank has Net Demand and Time Liabilities of ₹1,000 crore. At a CRR of 3%: Required CRR is 30 crore. The bank must maintain an average CRR balance of ₹30 crore with RBI over the prescribed reporting fortnight.

What exactly has RBI changed?

• RBI has not increased the CRR rate from 3% to 99%. It has increased the minimum proportion of the required CRR that banks must maintain every day. 
  • Earlier: 90% minimum daily maintenance of prescribed CRR
  • From 16 October: 99% minimum daily maintenance of prescribed CRR
  • Actual CRR rate: 3% unchanged

Eg. If the required CRR is ₹30 crore:

What is Net Demand and Time Liabilities (NDTL)?

• The liability base used to calculate CRR and certain other statutory banking requirements.
  • Demand Liabilities: Deposits or other qualifying liabilities payable on demand, such as current account balances.
  • Time Liabilities: Deposits and other qualifying liabilities payable after a specified period, such as fixed deposits.
  • Net Liabilities: The applicable liability base after adjustments prescribed by RBI, including relevant interbank liabilities and exemptions.
• CRR is calculated on the prescribed NDTL base, not simply on a bank's total assets or the sum of every deposit without adjustment.

Why has RBI increased daily CRR maintenance?

• Excess Liquidity in the Banking System
  • India's banking system experienced substantial surplus liquidity during August and September 2026.
  • Excess liquidity can push short-term money-market interest rates below the policy rate and complicate monetary policy transmission. 
• Better Control Over Daily Bank Reserves
  • Previously, banks could temporarily maintain only 90% of their required CRR and compensate by maintaining higher balances on other days.
  • The 99% rule significantly reduces this flexibility. It helps RBI manage short-term liquidity conditions more closely.
• Strengthening Monetary Policy Transmission
  • RBI raised the policy repo rate by 25 basis points to 5.50% in October 2026.
  • Excess liquidity can weaken the transmission of monetary tightening to overnight market rates.
  • Tighter daily reserve requirements, combined with other liquidity operations, can support closer alignment between money-market rates and the policy stance. 
• Liquidity Created Through Foreign Currency Inflows
  • Foreign Currency Non-Resident Bank deposits, or FCNR (B) deposits, contributed to banking-system liquidity.
  • Banks mobilised foreign currency deposits, and subsequent foreign-exchange swap operations helped provide rupee liquidity.
  • Government expenditure also contributed to temporary liquidity surpluses. 

How will the New Rule affect the Banking System?

• Daily CRR minimum rises to 99% 
• Banks have less flexibility to draw down reserve balances
• More disciplined daily liquidity management
• Potentially tighter overnight money-market conditions

Liquidity Management Instruments Used by RBI

• Open Market Operations (OMO)
  • Refers to RBI's purchase or sale of government securities in the financial market.
  • OMO Purchase: RBI buys government securities and injects liquidity into the banking system.
  • OMO Sale: RBI sells government securities and absorbs liquidity from the banking system.
  • On 9 October 2026, RBI announced an OMO sale of ₹25,000 crore for 13 October.
• Repo Rate
  • The repo rate is the policy interest rate at which RBI provides liquidity to eligible banks against approved securities through repurchase agreements.
  • A higher repo rate generally makes borrowing from RBI more expensive and supports tighter monetary conditions. In October 2026, the repo rate was increased to 5.50%.
• Standing Deposit Facility (SDF)
  • SDF allows RBI to absorb surplus liquidity from eligible banks without providing collateral.
  • It operates as the floor of the Liquidity Adjustment Facility (LAF) corridor under normal conditions.
• Variable Rate Reverse Repo (VRRR)
  • VRRR auctions allow RBI to absorb surplus banking-system liquidity for specified periods at market-determined auction rates.
  • They are particularly useful when excess liquidity is temporary.
• Marginal Standing Facility (MSF)
  • MSF provides an emergency overnight borrowing facility for eligible banks against permitted securities.
  • It normally forms the upper boundary of the LAF interest-rate corridor.

CRR vs SLR

Basel Standards and Their Relationship with CRR

• The Basel framework is developed by the Basel Committee on Banking Supervision (BCBS), based in Basel, Switzerland, and supported by the Bank for International Settlements (BIS).
• Its objective is to improve banking stability through stronger capital, liquidity and risk-management requirements.

Evolution of Basel Standards

Basel III: Three Major Pillars

• Pillar 1 (Minimum Capital Requirements): Banks must maintain regulatory capital against credit, market and operational risks.
• Pillar 2 (Supervisory Review): Regulators evaluate banks' risk management, capital adequacy and overall financial resilience.
• Pillar 3 (Market Discipline): Banks disclose financial and risk-related information to promote transparency.

Important Basel III Liquidity Standards

• Liquidity Coverage Ratio (LCR): Ensures that banks hold sufficient High-Quality Liquid Assets (HQLA) to withstand net cash outflows during a 30-day stress scenario.

• Net Stable Funding Ratio (NSFR): Ensures that banks maintain stable funding relative to their assets and activities over a one-year horizon.

Difference between CRR, LCR and NSFR

Impact of RBI's Decision 

• Impact on Banks
  • Banks will need to manage daily reserve balances more carefully.
  • Their flexibility to temporarily use CRR balances for other liquidity needs will decrease.
  • Some banks may rely more on interbank borrowing or RBI liquidity facilities to meet short-term funding requirements.
  • The actual cost impact will depend on individual banks' liquidity positions.
• Impact on Lending and Borrowers
  • The revised rule does not directly increase lending interest rates.
  • However, if it contributes to tighter money-market conditions, banks' short-term funding costs could increase.
  • The impact on home loans, personal loans, business loans and MSME credit will depend on broader monetary conditions and banks' pricing decisions.
• Impact on Inflation
  • Tighter liquidity conditions can support RBI's efforts to control inflation by influencing credit conditions and short-term interest rates.
  • However, the daily CRR maintenance change alone is unlikely to produce a large, immediate reduction in inflation.
• Impact on Financial Markets
  • Money Market: Overnight interest rates may face upward pressure if surplus liquidity declines.
  • Bond Market: OMO sales can increase the supply of government securities in the market, potentially putting upward pressure on bond yields.
  • Banking Sector: Banks may need more active treasury and liquidity management.
  • Exchange Rate: Liquidity tightening can influence rupee funding conditions, although exchange rates depend on several domestic and international factors.

Significance 

• Monetary Policy Effectiveness: Helps RBI maintain better control over short-term banking liquidity.
• Financial Discipline: Encourages banks to maintain reserve balances closer to the prescribed requirement each day.
• Liquidity Stability: Reduces excessive daily fluctuations in banks' use of mandatory reserves.
• Policy Coordination: Complements repo-rate decisions, OMO sales and other liquidity management operations.
• Financial Stability: Supports more predictable reserve management without changing the overall CRR rate.

Challenges 

• Reduced Flexibility: Banks have less freedom to manage temporary daily liquidity shortages.
• Funding Costs: Banks with tighter liquidity positions may face higher short-term borrowing costs.
• Uneven Impact: Smaller or less liquid banks may experience greater adjustment pressures than banks holding substantial excess reserves.
• Credit Transmission: Excessive liquidity tightening could affect credit conditions if combined with other restrictive measures.
• Market Volatility: Rapid changes in liquidity conditions may influence overnight interest rates and bond yields.

World Arthritis Day: Theme, Key Facts, History

Why in News?

World Arthritis Day is observed every year on 12 October to raise awareness about arthritis and rheumatic and musculoskeletal diseases (RMDs).

Key Facts

History 

• World Arthritis Day was established in 1996 by Arthritis and Rheumatism International (ARI) to increase global awareness of arthritis.
• It aims to improve public understanding of rheumatic and musculoskeletal diseases and their impact on everyday life.
• Over time, organisations such as EULAR have supported international awareness campaigns, patient education and improved access to healthcare.

What is Arthritis?

• Refers to a group of conditions that affect the joints and may cause pain, swelling, stiffness and reduced mobility. It can affect people of all ages, although some forms are more common among older adults.
• Arthritis includes more than 100 different conditions affecting joints and related tissues. Severe or untreated arthritis may cause chronic pain, joint damage, disability and reduced quality of life.

Major Types of Arthritis

• Osteoarthritis: The most common form of arthritis, involving deterioration of joint tissues. It commonly affects the knees, hips and hands.
• Rheumatoid Arthritis: A chronic autoimmune disease in which the immune system attacks the body's tissues, particularly the joints.
• Gout: A form of inflammatory arthritis caused by the accumulation of monosodium urate crystals in joints.
• Psoriatic Arthritis: An inflammatory joint condition associated with psoriasis, a chronic skin disease.
• Juvenile Idiopathic Arthritis: A group of inflammatory joint diseases that begin before the age of 16.

Global Burden of Arthritis

• According to the World Health Organization (WHO), approximately 528 million people worldwide were living with osteoarthritis in 2019.
• About 73% of people with osteoarthritis were older than 55 years, while approximately 60% were women.
• WHO estimated that around 18 million people worldwide were living with rheumatoid arthritis in 2019.
• Osteoarthritis is a major contributor to disability and rehabilitation needs globally.

Arthritis in India

• Arthritis is an important public health concern in India because of its impact on mobility, productivity and quality of life.
• India's ageing population, rising prevalence of obesity and changing lifestyles may increase the burden of osteoarthritis.
• Rural and underserved areas often face difficulties in accessing rheumatologists, physiotherapists and specialised healthcare facilities.
• Delayed diagnosis and inadequate treatment can contribute to chronic pain, disability and financial difficulties.

Causes and Risk Factors

• Ageing: Increasing age is a major risk factor for osteoarthritis.
• Obesity: Excess body weight places additional stress on weight-bearing joints.
• Genetic Factors: Family history may increase susceptibility to certain types of arthritis.
• Autoimmune Conditions: Abnormal immune responses contribute to diseases such as rheumatoid arthritis.
• Joint Injuries: Previous injuries and repetitive joint stress may increase the risk of osteoarthritis.

Importance
