Self-insurance and structural hedges

By the end of this lesson you can

  • Rank the three responses to a risk by what each actually costs
  • Explain why an individual cannot self-insure a concentrated exposure and an institution can
  • Compute the tail reduction that separation buys, and what it costs
  • Identify the structural hedges available to you that require no counterparty at all

This lesson opens with KuCoin, 26 September 2020.

What happened
On 26 September 2020 roughly $281M of assets were drained from KuCoin's hot wallets. Over the following weeks the exchange recovered about 84 percent of the funds, largely because token issuers were able to freeze balances, re-deploy contracts or reissue supply, and because other venues froze deposits from the identified addresses. The remaining share, reported at about $45.55M, was met from KuCoin's own insurance fund. Services were restored progressively through October and November 2020, and the exchange stated that no user bore a loss. The recovery therefore came from two sources, neither of which was a policy purchased from a third party.
The decision point
This is what self-insurance looks like when it works, and it worked because the party retaining the risk was large enough to hold a reserve against it. It is also a reminder of what the 84 percent actually was, being centralized parties exercising powers over their own tokens, which per J306-01 is a power that exists whether or not it is used in your favor. Neither half of the recovery is available to an individual holder.

What you will be able to answer

  • What are the three responses to a risk?
  • Why can an institution self-insure and you cannot?
  • What does separation buy?
  • What is a structural hedge?

Orientation and Year One are open: anyone can read them without an account. From Year Two onward the lessons are for enrolled learners, because progress through the later years only means anything if it is tracked against a record.

It is free. We do not sell the list and there is nothing to buy at the end of it.

Contested

The KuCoin recovery figures come largely from the exchange's own statements at the time and were not independently audited. The reported total varies between about $281M and $285M and the recovered share between 84 percent and a claimed full recovery. The mechanism, being partial recovery through issuer action plus a reserve meeting the balance, is well supported and the precise split is not.

R406-04 covers hedging instruments properly at Senior level, including options, futures and basis construction. This lesson covers only the hedges that require no counterparty, being structural changes to how a position is held. Keep the split and do not introduce derivatives here.

S207-02 owns position sizing. This lesson uses sizing as one of four structural tools rather than re-deriving it. Keep the split.
