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.

Where it breaks down

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.

How it connects

How hidden exposures turn one fund's losses into a market-wide retreat from lending.

Check yourself

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 the sources establish

  • After Russia's August 1998 default, LTCM's highly leveraged positions produced severe losses that threatened a disorderly liquidation.

  • Counterparties could see their own contracts with LTCM but not the fund's full portfolio, intensifying fear that forced sales would transmit losses through the system.

  • Adverse selection is one transmission channel in a funding crisis: when lenders cannot identify the weakest balance sheet, they retreat from counterparties that may still be sound.
