UST's recovered peg was an outcome, not proof of its mechanism

Two explanations for the same chart

Editorial analysis · based on the cited records

A price returning to its target can be consistent with several explanations. In the Terraform record, the public explanation emphasised an autonomous protocol, while DOJ described undisclosed purchases by a trading firm. The chart alone could not tell a reader which explanation was correct. This is a causal-evidence problem, not merely a disagreement about whether a price briefly reached one dollar.

Test the dependencies

Editorial analysis · based on the cited records

A useful review asks what external capital, counterparties and decision-makers the mechanism requires. If emergency support is possible, the ability and willingness to supply it matter. If reserves are described as independently governed, control arrangements need their own evidence. A technical diagram that omits those dependencies can overstate autonomy even when individual components are correctly described.

Keep the conclusion bounded

Editorial analysis · based on the cited records

The sentencing record supports conclusions about Kwon's conduct and the representations identified in that case. It does not automatically establish the safety or fraudulence of another stablecoin. European readers should also distinguish economic design from regulatory authorisation: ESMA's warning explains that protection depends on the asset and service involved. Neither a historical price chart nor an authorisation label alone answers every risk question.

Separate mechanism evidence from outcome evidence

Editorial analysis · based on the cited records

A useful causal diagram for a peg has at least three paths: ordinary arbitrage, reserve deployment and discretionary outside support. All three can lead to the same observed price. Evidence of the outcome cannot identify which path supplied the buying pressure. The May 2021 episode described by DOJ matters because the marketed explanation omitted an outside actor. For a different stablecoin, the next research step would be identifying the disclosed redemption and support rules, not declaring that any return to a target price proves autonomous resilience.
