What is Capital Adequacy Ratio (CAR)? Understanding Capital & Solvency
The Answer
Capital Adequacy Ratio (CAR) measures a bank's capital base (Tier-1 and Tier-2 capital) relative to its Risk-Weighted Assets (RWA). A Capital Adequacy Breach occurs when this ratio falls below regulatory thresholds (typically 9% to 12% in India), threatening the bank's legal license and solvency.

Why it Matters
CAR is a bank's ultimate survival buffer. If depositors run or loans default, CAR absorbs the losses. A breach means the bank lacks the capital equity to support its lending risk, forcing regulatory intervention or shutdown.
Sentinel Insight
“CAR is the regulator's redline. A bank whose CAR drops near the 11.5% Basel-III boundary must immediately raise expensive equity or freeze lending.”
📊 How to Interpret
In Risk Context
In Flagium's engine, Capital Adequacy Breach (F10, Weight: 15) is a high-severity solvency flag. A breach below critical limits is categorized as a terminal solvency threat.
Deep Dive
Capital Adequacy Ratio: Basel III Solvency Limits
The Capital Adequacy Ratio (CAR), also known as Capital-to-Risk-Weighted-Assets Ratio (CRAR), ensures that financial institutions have enough equity cushion to absorb a reasonable amount of losses before going insolvent.
The CAR Formula
Where:
- Tier 1 Capital: Core equity capital (paid-up capital, free reserves) that can absorb losses without forcing the bank to stop trading.
- Tier 2 Capital: Supplementary capital (subordinated debt, revaluation reserves, hybrid instruments) that provides loss absorption on liquidation.
- Risk-Weighted Assets (RWA): The bank's total assets weighted by risk factors. Cash carries a 0% weight; home loans carry a 35%-50% weight; unsecured credit cards/personal loans carry a 125%-150% weight.
How Flagium Detects Capital Adequacy Breaches
Flagium monitors the Capital Adequacy Ratio (CAR) and CET-1 ratio. If CAR falls below the safety limit (Basel III + CCB) or CET-1 drops below , the engine triggers the F10 flag.
RBI Prompt Corrective Action (PCA)
Under Basel III rules, the RBI mandates a minimum CAR of 9.0% for commercial banks plus a 2.5% Capital Conservation Buffer (CCB), totaling 11.5%.
If a bank's CAR falls below these limits, the RBI triggers Prompt Corrective Action (PCA). The regulator takes control, placing strict limits on:
- Dividends distribution and executive bonuses.
- New branch expansions.
- Lending to high-risk borrowers or large corporates.
- In extreme cases, the bank is merged or shut down to protect depositor capital.
Early Warning Signs of Capital Breaches
- Risk-Weighted Assets growing faster than Tier-1 Capital: Lending is shifting toward unsecured, high-yield assets without corresponding equity infusion.
- CET-1 Ratio compressing: The Core Equity Tier-1 (CET-1) ratio is the purest form of CAR. If CET-1 falls below 8.0%, the bank is highly vulnerable.
- Rising NPAs consuming Capital: If write-offs and provisions outpace retained profits, the bank's equity cushion is eroded.
