Capital adequacy ratios shape the resilience of bank balance sheets, a core driver of financial system stability.
We outline how CAR informs long-only portfolio construction in bank equities and why excess capital matters for compounding.
Key takeaways
- Basel III minima set the floor; excess CET1 capital drives resilience and lending capacity.
- CAR levels influence bank equity drawdowns and recovery speed through credit loss absorption.
- We integrate CAR trends with profitability, funding, and liquidity to allocate risk budgets.
Market Context Now
Year to date 2020, banks are navigating a sharp economic shock, volatile funding conditions, and uncertain credit costs. For long-only investors, the dispersion of capital strength across franchises is wide, increasing the importance of balance-sheet quality and through-cycle underwriting.
As at June 2020, Basel III minimums are 8 percent for total capital, 6 percent for Tier 1, and 4.5 percent for Common Equity Tier 1, each measured against risk-weighted assets. These thresholds anchor regulatory capacity, yet equity outcomes hinge on buffers above minima, the mix of capital, and the pace of internal capital generation.
We therefore emphasise the interaction between CAR, pre-provision profitability, and loan-loss provisioning. Banks with durable excess capital can continue to lend, support the real economy, and sustain distributions when permitted by regulators.
Our Research Lens
We take a research-driven, long-only perspective that evaluates CAR as a live indicator of loss absorption, governance quality, and earnings resilience. We assess the quality of capital, the gap to regulatory and management targets, and the credibility of capital plans.
Our process tests the sensitivity of capital to adverse scenarios, focusing on risk-weighted asset density, model changes, and the stability of internal capital generation. We integrate market signals, supervisory actions, and disclosures into a structured view that seeks to compound capital across full market cycles.
At Carvina Capital Pte. Ltd., disciplined risk management guides exposure, increasing weights where buffers are demonstrably robust and reducing risk where capital trajectories depend on optimistic macro assumptions.
Portfolio Construction
Position sizing reflects excess CET1 relative to requirements, the volatility of capital drivers, and the liquidity profile of the shares. We allocate risk budgets preferentially to franchises with consistent capital generation, conservative asset-quality trends, and diversified funding.
Liquidity is managed at both portfolio and position levels to preserve flexibility in stressed markets. We maintain capacity to add to high-quality banks during dislocations when forward capital formation remains intact, and we limit names where capital relies on pro-cyclical fair-value gains. ESG Integration in Practice Governance and risk culture are central to CAR sustainability.
We incorporate board oversight, remuneration alignment, and disclosure quality into our assessment of capital plans, and we monitor environmental exposures where they influence asset quality, collateral values, and scenario design.
Signals We Are Watching
We monitor quarterly changes in CET1 ratios versus management and regulatory targets, because inflections often precede valuation re-rating. We track trends in risk-weighted asset density and model updates that can rebase reported capital. We review funding-mix shifts, including deposit stability and wholesale reliance, alongside distribution restrictions. We also evaluate capital generation from core earnings after credit costs to judge the durability of compounding.
Sustained excess CET1 above internal targets has historically reduced downside volatility in bank equities over the subsequent year.
Strategic Considerations
Capital adequacy is not a static constraint, it is a strategic asset. As at June 2020, investor focus remains on the balance between precautionary provisioning, regulatory guidance, and the pace of economic normalisation. Our expectation is that dispersion in outcomes will remain elevated, which rewards attention to capital quality and repeatable internal generation.
For portfolio construction, we prioritise banks with credible buffers, resilient pre-provision earnings, and conservative risk-weight methodologies. Where capital cushions are thin or assumption-dependent, we size positions modestly and require stronger upside to compensate for recapitalisation risk.
Carvina Capital continues to apply this framework across our long-only public-equity strategies, and we are evaluating how the same discipline could support potential products accessible to retail investors. Our objective is consistent: use robust, research-led assessment of CAR to enhance resilience and maintain the conditions for compounding through the cycle.
