# Risk-Weighted Assets

> Risk-weighted assets (RWA) are a bank's assets and off-balance-sheet exposures, each multiplied by a risk weight set in the capital rules. RWA is the denominator of the CET1, tier 1 and total capital ratios, so it sets how much capital a bank must hold for the risks it takes.

## Formula

```
RWA = Σ (Exposure Amount × Risk Weight) + Market Risk RWA
```

Under the US standardized approach in 12 CFR Part 217 (Part 3 for national banks, Part 324 for FDIC-supervised banks), each exposure gets a risk weight: 0% for cash, reserves and US Treasuries, 20% for exposures to US banks and most agency securities, 50% for qualifying first-lien residential mortgages, 100% for most commercial loans, 150% for past-due loans and high-volatility commercial real estate, and higher weights for some equity and securitization exposures. Off-balance-sheet items are first converted to on-balance-sheet amounts with credit conversion factors. Banks with a trading book add market risk RWA, and the largest banks also compute RWA under the advanced approaches.

## Why it matters

RWA turns a bank's asset mix into the base for its capital requirement. Two banks with the same total assets can need very different capital: one holding mostly Treasuries carries little RWA, one holding construction loans carries a lot. A dollar of RWA reduction lowers required capital just as a dollar of new capital raises the ratio, which is why banks manage both.

## How to read it

Divide RWA by total assets to get RWA density. Community banks with loan-heavy books often run 65% to 80%; large banks with big securities, cash and trading books run lower. Low density is not the same as low risk: risk weights ignore interest rate risk, so a bank full of long-dated Treasuries can carry little RWA and large unrealized losses at the same time. Read RWA with the leverage ratio, which ignores risk weights altogether.

## Thresholds

| Range | Reading | What it means |
|---|---|---|
| Low density (< 50%) | Conservative mix | Asset base tilted to low-risk-weight holdings. |
| 50–70% | Typical | Balanced asset mix for a commercial bank. |
| 70–90% | Loan-heavy | Credit-intensive balance sheet that needs more capital. |
| > 90% | Aggressive | Dense, high-risk-weight book. |


## Worked example

At June 30, 2026, JPMorgan Chase Bank, N.A. reported standardized risk-weighted assets of $2,013,591 million against total assets of $4,091,315 million, an RWA density of 49%. Its common equity tier 1 capital of $302,585 million gives a standardized CET1 ratio of $302,585 million / $2,013,591 million = 15.03%. Under the advanced approaches its RWA was $1,881,276 million and the same capital gave 16.08%; the bank must meet its requirements on both, so 15.03% is the binding figure.

## Questions

### What does RWA mean?

RWA stands for risk-weighted assets: a bank's exposures scaled by their credit risk under the capital rules. Regulators set the capital a bank must hold as a percentage of RWA.

### What is the formula for risk-weighted assets?

RWA = the sum of each exposure times its risk weight, plus market risk RWA for banks with a trading book. A $10 million commercial loan at a 100% weight adds $10 million of RWA; $10 million of Treasuries at 0% adds nothing.

### Why use risk-weighted assets instead of total assets?

Total assets treat a Treasury bill and a construction loan the same. Risk weighting asks for more capital against riskier assets, so the requirement follows what the bank actually holds.

### Does RWA capture interest rate risk?

Largely no. Standardized risk weights reflect credit risk, plus market risk for trading books. The interest rate risk behind the 2023 unrealized securities losses is not in RWA, which is why the leverage ratio and AOCI matter alongside it.

## Related metrics

- [Common Equity Tier 1 Capital Ratio](https://www.bankregreports.com/glossary/cet1-ratio/): The CET1 ratio measures a bank's highest-quality capital (common stock and surplus, retained earnings and, for banks that have not opted out, accumulated other comprehensive income, less regulatory deductions) against its risk-weighted assets. It is the most-watched single capital indicator in US bank supervision after the 2013 Basel III reforms.
- [Credit Conversion Factor](https://www.bankregreports.com/glossary/credit-conversion-factor/): A credit conversion factor (CCF) is the percentage that turns an off-balance-sheet exposure, such as an unused loan commitment or a standby letter of credit, into an on-balance-sheet credit equivalent amount. The credit equivalent amount is then risk-weighted like a loan to the same borrower and added to risk-weighted assets.
- [Tier 1 Risk-Based Capital Ratio](https://www.bankregreports.com/glossary/tier1-rbc/): The Tier 1 Risk-Based Capital ratio measures a bank's Tier 1 capital (CET1 plus Additional Tier 1 instruments) against its risk-weighted assets. It is the broader of the two Tier-1 capital measures and is still the headline capital metric for most banking comparisons.
- [Total Risk-Based Capital Ratio](https://www.bankregreports.com/glossary/total-rbc/): The total risk-based capital ratio is a bank's total regulatory capital (tier 1 plus tier 2) divided by its risk-weighted assets. US rules require at least 8%, 10% to be well capitalized, and 10.5% including the capital conservation buffer.
- [Tier 1 Leverage Ratio](https://www.bankregreports.com/glossary/leverage-ratio/): The tier 1 leverage ratio is a bank's tier 1 capital divided by its average total consolidated assets. Unlike the risk-based ratios it gives every asset the same weight, so it caps how far a bank can stretch its balance sheet whatever the asset mix.
