Which situation is adverse selection?

Lenders charge one high rate because they cannot tell safe borrowers from likely defaulters, so safer borrowers walk away.. Right. The selection happens before the deal closes: hidden risk shows up disproportionately, and safer participants leave.

In a funding panic with hidden exposures, why do lenders often retreat from everyone?

Because any borrower could be hiding the largest losses, sound firms get priced like weak ones.. Yes. When the weakest balance sheet cannot be identified, lenders treat every counterparty as if it might be the weak one.

What happened at the New York Fed on 23 September 1998?

Fourteen financial institutions agreed to inject $3.625 billion into LTCM in exchange for 90 percent of the fund.. Right. Creditors put up private capital for control of the fund; the Fed organized the meeting but spent no public money.

What hidden knowledge does to markets

How did one hedge fund make the world's largest banks afraid to trade?

01 · Word

Adverse selection

Pronounced ad-VURS suh-LEK-shun

noun

Adverse selection occurs when one side knows more about risk than the other. The people or assets most likely to cause a loss enter the deal, while safer participants stay away.

Examples

When lenders cannot tell safe borrowers from likely defaulters, they charge one high rate. Safer borrowers walk away; riskier ones still accept.
In a funding panic, the banks most eager to borrow may be those hiding the largest losses, so lenders pull back from everyone.

Origin

The term began in insurance: people who know they face greater risk are more likely to buy coverage when insurers cannot price them separately. Economists later generalized the pattern to credit, labor, and financial markets.

When every balance sheet looks dangerous

In a crisis, lenders cannot see every position held by a bank or hedge fund. The firms most desperate for cash may be those hiding the largest losses. Because any borrower could be the weak one, lenders raise collateral demands, shorten maturities, or refuse to lend. Sound firms are caught in the same retreat, and markets seize up.

That logic intensified the turmoil after Russia defaulted on domestic debt in August 1998. Long-Term Capital Management, a highly leveraged hedge fund with enormous positions across global markets, began losing billions. Its counterparties knew their own contracts with LTCM but not the fund's full portfolio, and feared that forced liquidation would spread losses through the financial system.

When nobody can identify the weakest balance sheet, everyone is priced as if they might be it.

Markets need more than collateral; they need credible information about leverage, exposures, and who ultimately bears the loss.

Limits and context

Adverse selection did not cause the 1998 crisis by itself. Russia's default, leverage, crowded trades, fragile funding, and the prospect of fire sales all mattered. The model explains one crucial transmission channel: hidden exposures made lenders retreat from counterparties and assets that might have been sound.

The same pattern appears in sovereign debt, banking panics, insurance, hiring, and any market where one side knows more about the risk.

Fourteen banks in one room

Federal Reserve Bank of New York, 23 September 1998

Long-Term Capital Management had lost most of its capital after Russia's default broke trades built on small price differences and vast leverage. The Federal Reserve Bank of New York brought major creditors together; fourteen financial institutions agreed to inject $3.625 billion in exchange for 90 percent of the fund. The aim was not to save its owners, but to prevent a disorderly liquidation from destabilizing markets worldwide.

The fund: LTCM
Participants: Fourteen
Capital: $3.625 billion

The caveat

The New York Fed organized the meeting but supplied no public money, and historians still debate how disastrous an uncontrolled failure would have been. The episode was a private recapitalization, not a government bailout.

The information problem was systemic. Each bank could see its own contracts with LTCM, but no one could see the complete web of leverage and overlapping positions. With the weakest counterparty impossible to identify, lenders had reason to assume danger everywhere and withdraw. A problem inside one fund threatened to become a market-wide refusal to trade.

The rescue became a warning that hidden leverage inside one fund could threaten the financial system.

The connection

Hidden risk changes who is willing to trade. The riskiest participants keep seeking funds, safer participants retreat, and uncertainty can freeze a market before anyone knows where the losses sit.
