What it means
Every lender and insurer needs a consistent way to decide who gets a loan or a policy. Underwriting standards put those decisions in writing so that they are applied fairly and repeatedly, rather than left to individual judgement.
They cover what information must be collected, how it is checked and what score or ratio is acceptable. For a mortgage lender, typical standards include a maximum loan-to-value ratio, a maximum debt-to-income ratio, minimum credit scores, proof of income and rules on the type of property.
For a business lender, they may include minimum interest cover, collateral requirements and limits on exposure to one sector. For an insurer, they set which risks are acceptable and at what premium.
Standards move with the economic cycle. When competition is strong and losses have been low, lenders tend to loosen them to win business, and when losses rise they tighten them again.
Periods of very loose standards have been linked to credit bubbles, because borrowers who could not repay were given loans. Regulators watch standards closely because they affect the safety of the whole financial system.
They may issue guidance on acceptable ratios, require stress tests and review samples of loans. Banks also have internal credit policies, with approval limits that mean larger or riskier loans need senior sign-off.
Exceptions are normal but must be controlled. A loan that falls outside the standards can still be approved with compensating strengths, such as a larger deposit, but exceptions should be recorded and monitored.
Too many exceptions are an early warning that the standards are not being followed in practice. From a customer's point of view, understanding the standards helps.
A business owner who knows a lender needs interest cover of at least 2 times can improve the figures before applying, instead of being surprised by a refusal.
In practice
Real-world examples.
Example
A mortgage lender sets a maximum loan-to-value of 80% for standard borrowers. A buyer who wants to borrow 90% of a property price is asked to raise the deposit or take mortgage insurance, depending on the lender's policy.
Example
A commercial bank requires that a company's earnings before interest and tax cover its interest payments at least 2 times. A retailer with $1,500,000 of earnings and $900,000 of interest has cover of only 1.67 times and has to restructure its debt before the loan is approved.
Example
A property insurer will not offer cover for buildings with outdated wiring unless the owner has an electrical inspection certificate. The standard limits fire claims and keeps premiums for other customers affordable.
Formula
Calculation
Debt-to-income ratio = Monthly debt payments / Gross monthly income
Loan-to-value ratio = Loan amount / Property value
A lender's standards say the debt-to-income ratio must not exceed 40% and the loan-to-value ratio must not exceed 80%.
A borrower earns $8,000 a month before tax and would have total monthly debt payments, including the new loan, of $2,800.
Debt-to-income = $2,800 / $8,000 = 0.35, or 35%, which is below the 40% limit.
The borrower wants a $320,000 loan against a property valued at $400,000.
Loan-to-value = $320,000 / $400,000 = 0.80, or 80%, which is exactly at the limit and so is acceptable. If the borrower asked for $340,000, the ratio would be $340,000 / $400,000 = 85%, which exceeds the standard and would need a larger deposit or an approved exception.Case study
Seen in the real world.
Greenfield Credit is an illustrative, fictional consumer lender that grew quickly by relaxing its standards. It removed income checks for loans under $15,000 and accepted borrowers with weaker credit scores to compete with rivals offering faster approvals.
Applications doubled in a year, and management celebrated record lending volumes. Within two years, though, 12% of the new loans were behind on payments compared with 4% on its older book, and the company had to set aside large provisions.
The board restored income verification, set a debt-to-income limit and created a monthly report on exceptions. The illustrative lesson is that standards are cheap to relax and expensive to rebuild, so a decision to loosen them needs the same scrutiny as any other major risk choice.
Watch out
Common mistakes.
- Treating underwriting standards as bureaucracy, when they are the main control on how much credit or insurance risk a firm takes.
- Loosening standards to hit volume targets without measuring what happens to losses later.
- Allowing exceptions to become routine, which quietly turns the standard into a suggestion.
Questions
People also ask.
Do all lenders use the same standards?
No, each lender sets its own within the limits of regulation, which is why one lender may approve an application that another rejects.
What are the most common measures in underwriting standards?
Credit score, debt-to-income, loan-to-value, interest cover, collateral and years in business are the usual ones.
How can a borrower improve the chance of approval?
Reduce existing debt, increase the deposit or collateral, document income clearly and correct errors on the credit report before applying.
