Terra lawsuit frames collapse as a targeted currency attack by Jane Street

When Terra Luna collapsed in May 2022, most of high finance barely knew it existed — myself included.

Yes, I was aware something called Terra was doing the rounds, but I had no real understanding of its inner workings. The same was true of many other monetary experts who have since become expert authorities on stablecoin mechanics and regulation. The collapse and its implications caught most of us off guard.

To drive that point home, the week of the great unravelling — which began in earnest on Monday, May 9 — I happened to be moderating a workshop with some of the best-known academics studying stablecoins. All were fascinated by the developments, but most, like me, had been unfamiliar with TerraLuna until that week. At that time, academic understanding of stablecoin operations was largely limited to this list of inquiries and academic works.

The incident has since become a go-to academic reference for proving the intrinsic instability of stablecoins. Scores of high-level academic works, among them by Igor Makarov of the LSE, Antoinette Schoar of MIT, Darrell Duffie of Stanford, and Raphael Auer, have scrutinized the finer details of the destabilization, mostly concluding that the incident demonstrates why stablecoin regulation and backing requirements are necessary.

But now, a new legal complaint filed by Terraform Labs against Jane Street on February 23 threatens, if proven in court, to expose much of that analysis as strikingly incomplete.

The complaint alleges that Terra’s depeg may, in fact, have been caused by materially informed and strategically timed transactions by Jane Street during the critical de-pegging window. If substantiated, it would imply that asymmetric information and insider positioning played a much bigger role in the “spontaneous” bank-run dynamic that brought down TerraLuna.

Whether those allegations ultimately withstand judicial scrutiny remains to be seen, but their emergence significantly complicates the prevailing narrative that the collapse can be explained by structural design flaws alone.

But the disclosure contains far more than a legal defence — it reads at times like an inadvertent whistleblowing document, offering rare insight into how the sector actually operates behind the scenes.

Below is an outline — based on what can be gleaned from the filing — of the key revelations that merit closer scrutiny into how the crypto and traditional finance ecosystems interoperate, including the role that insiders and dominant market makers such as Jane Street, a former training ground for Sam Bankman-Fried, and Jump Trading played in both supporting and destabilising the TerraLuna system for profit.

In a nutshell, the complaint suggests that many of the structural suspicions about how crypto markets operate — and how they interact with insiders at the expense of retail investors — were not entirely misplaced.

1. Terraform was engaged in a close and evolving trading relationship with Jane Street dating back to 2018, initially via OTC discussions but becoming materially more significant in 2022 after Bryce Pratt — a former Terraform intern — joined Jane Street and helped establish direct communication channels between the two firms.
2. While not a formal partnership, the complaint implies that Jane Street’s role as liquidity provider and OTC counterparty functioned as a form of embedded support — one that was instrumental to the growth and credibility of the Terra ecosystem. In markets, sustained liquidity provision is itself a form of investment in a product’s viability.
3. The relationship appears to have been actively cultivated. Jane Street expressed interest in creating markets in Terraform’s primary tokens, UST and Luna, with a view to generating trading and market-making returns, including via OTC capability. The complaint alleges that privileged access to internal discussions materially enhanced that trading advantage.
4. Jane Street was not described as a conventional equity investor in Terra. But its preferential position as a market maker, liquidity participant and sophisticated counterparty effectively made it an ecosystem backer. Liquidity — especially in fragile algorithmic systems — is capital.
5. According to the complaint, that support did not fully crystallise until Jane Street allocated Pratt — whose prior employment at Terraform allegedly “uniquely situated” him to pass information — to maintain active lines of communication with former colleagues. The complaint suggests this conduit became integral to Jane Street’s trading strategy during Terra’s growth phase — a period during which the combined market capitalisation of UST and Luna swelled to roughly $50–60bn at its peak in early 2022, before collapsing to near zero within days in May.
6. Terraform is portrayed as perceiving aspects of the relationship as confidential and not widely known to public investors. Transparency about the degree of strategic interaction between issuer and liquidity provider appears, at minimum, limited.
7. The complaint further notes that Terraform itself characterises UST and Luna as “investment contracts” for purposes of securities-law claims — a detail that may weigh heavily in ongoing industry arguments about whether crypto tokens fall outside the Howey framework.
8. When instability struck Terra in 2021, an unnamed large trading firm intervened to help restore the peg. By 2022, Luna Foundation Guard (LFG) had amassed over $3 billion in reserves to defend UST. These reserves functioned in practice as a stabilisation “war chest” — a quasi-sovereign-style backstop funded not by taxation or central bank balance sheets, but by venture capital, token issuance and private capital accumulation.
9. The complaint alleges that one of the key “material insights” that Jane Street benefited from concerned Terraform’s plan to withdraw 150 million UST from the Curve 3pool on May 7, 2022 — a move not publicly disclosed at the time. Within minutes of becoming aware, Jane Street supposedly executed what the filing describes as its largest single UST trade in that pool — an 85 million UST sale. The complaint alleges that this trade precipitated the broader sell-off that followed.
10. Unbeknownst to public investors, Terraform had also engaged Jump Trading as a defender of the peg, including through LFG-funded operations. The complaint characterises Jump as operating in a “temporary insider” capacity because of its stabilisation role. Knowledge of that defence architecture — and of its limits — is alleged to have circulated among select actors.
11. LFG ultimately accumulated enormous UST and Luna exposures in the course of peg defence, absorbing losses as the system unravelled.
12. The complaint further alleges that Jane Street was approached to assist in stabilisation financing during the crisis, including potential discounted purchases of Bitcoin or Luna, but instead traded in UST while in possession of sensitive information about liquidity conditions.

Separate but relevant context:

1. There is a key historical parallel worth noting. The alleged catalyst for the May 7 sell-off — insider awareness that Terraform planned to withdraw 150 million UST from the Curve 3pool in preparation for migrating liquidity to a larger 4pool — has echoes of how coordinated gold pools once operated. In the 1960s London Gold Pool, for example, central banks collectively defended the dollar-gold peg by supplying reserves into the market.When speculative pressure intensified in 1968 and confidence in the pool’s capacity wavered, the arrangement was abruptly restructured into a two-tier system. In systems built on pooled liquidity, even transitional adjustments can become destabilising if sophisticated actors move before the defence is fully in place. Knowledge of reserve movements or internal reorganisation could itself become destabilising if acted upon pre-emptively.
2. Jump Trading reportedly suffered substantial losses in 2022 linked to cryptocurrency trading. Much of that was supposedly linked to the FTX implosion, but the current complaint suggests Terra Luna may also have played a role.
3. The majority of claimants in the bankruptcy proceedings are from South Korea, and the United States, but Singapore, Russia, and notably Italy are also very well represented.
4. Today, Jane Street is responsible for roughly 10 percent of all equity trading volume in North America, meaning the way it operates has direct and material implications for the integrity of U.S. capital markets. The firm’s growth since its foundation in 1999 has also been extraordinary, with net trading revenues exceeding $24 billion in the first three quarters of 2025.
5. The group’s core expertise has always lain in market making — particularly of exchange-traded funds — where it has often served as an authorised participant, occupying structurally central roles in liquidity architecture.

Echoes of Soros vs the BoE

There are many more insights to be drawn from these revelations. Chief among them, arguably, is that stablecoins often operate more like miniature currency boards than decentralised private-sector ventures. The difference is that these systems are bootstrapped not by national reserves, but by private — and often highly secretive — capital pools, supported by strategic allegiances with dominant liquidity providers.

Such systems also appear to depend on their own de facto “plunge protection teams” — aka insider relationships with sophisticated trading firms capable of defending (or attacking) pegs based on granular knowledge of liquidity positioning. This is not unlike China’s dependence on its so-called National Team, the state-linked institutions mobilised to defend domestic equity markets during periods of stress.

In the crypto context, however, the backstop is not sovereign capital per se but a small circle of sophisticated and interested trading firms, brought into defence strategies with the implicit expectation of preferential access, structural advantage or enhanced returns. But perhaps too, based on an informal understanding that profits derived from such arrangements will later be reinvested in ideologically aligned philanthropic causes or as political donations. A financial-based power playbook based on insider dealing that is now, inadvertently, being exposed by way of the Epstein revelations.

Academics and regulators appear blissfully unaware about how these defence arrangements are structured, and most importantly, “networked” in practice because they are, by design, proprietary and opaque.

Moreover, the complaint itself contains extensive redactions, highlighting the sensitivity of certain communications and trading mechanics.

Yet, what is increasingly clear is that the events of May 2022 resemble — structurally if not politically — classic currency attacks, in which knowledge of reserve constraints and defence capacity determines outcome.

I am not suggesting coordination with state actors. But in an era where financial markets are increasingly instruments of geopolitical competition, and where information asymmetry is itself a strategic asset, it is reasonable to ask whether such liquidity architectures are more than merely commercial. State-aligned in some cases, in others, with more shadowy networks or hostile foreign actors.

Bloomberg, for example, has previously reported on Jane Street co-founder Robert Granieri’s alleged links to a failed coup attempt — an episode he has said he was misled about. While separate from the issues at hand, the incident illustrates how global trading networks can intersect with geopolitical risk in opaque and sometimes unexpected ways.

Consider also the proximity between Jane Street alumni and Sam Bankman-Fried, and the way FTX and Alameda operated with related-party dynamics that blurred the line between liquidity provision and privileged information flows. Finally, consider the political and philanthropic capital that flowed from those structures.

What appears to be emerging, I would argue, is a recurring model in which liquidity, influence, opacity, and systemic leverage converge — not solely in pursuit of profit, but potentially in service of broader ideological objectives. It is historically a playbook most famously associated with George Soros, who channelled profits from his bet against the Bank of England into the creation of politically active philanthropic foundations.

Personal anecdotal experiences support that notion.

For example, in 2014, I was invited to Jane Street’s New York offices to speak to a room of young quantitative traders about how modern financial journalism works — including expanding on my reporting on delta-one strategies and the mechanics through which they generate returns. That reporting examined how retail flows can be intermediated, warehoused, and systematically recycled to produce outsized proprietary trading profits. At the time, I understood the dynamic primarily as a story of sophisticated financial engineering and institutional opportunism — an aggressive but familiar feature of modern markets.

At lunch, the traders quizzed me intently about my work on metals warehousing, warrants, contango, and backwardation, and how it all worked.

What struck me immediately was how ignorant many of them were about the underlying fundamentals and mechanics of the markets they were trading. I was shocked to discover that many had never even heard of a warrant, yet, in many cases, represented some of the most active trade in metals ETFs.

In hindsight, the episode is revealing. If retail capital can be systematically aggregated and deployed through opaque trading architectures, it begins to resemble something more structural than mere profit extraction — closer, perhaps, to a modern form of war-bond financing, where dispersed retail savings are mobilised at scale for strategic ends largely invisible to the investors themselves.

That comparison feels apt given what I noticed in the office itself. The walls were covered in World War I and World War II propaganda posters. At the time, I dismissed it as quirky décor — the kind of ironic aesthetic you might expect from mathematically minded but eccentric founders. But in a world where capital markets increasingly double as arenas for strategic competition, the symbolism seems harder to ignore.

I have since identified one of the posters I noticed on the right-hand side of the in-house auditorium as a well-known U.S. Treasury World War I recruitment piece from 1918. It was designed to encourage women to purchase War Savings Stamps to finance the war effort. The image depicts Joan of Arc rallying American women to “save your country” by supporting the campaign — a striking blend of patriotism, mobilisation, and financial participation.

Later, I was shown the office of one of the founders. On display was an Enigma machine, alongside images of Alan Turing and Bletchley Park — a carefully curated aesthetic that leans heavily into the mythology of wartime codebreaking.

At the time, I thought it was another quirk, perhaps emphasizing the firm’s self-image as a place where markets are puzzles to be deciphered, and advantage belongs to those who can break the code first. But other rooms suggested there was more to it than that, not least the in-house gaming room dedicated to helping traders perfect casino-style card games such as Texas Hold’em and poker — games built on probability, psychology, and calculated risk.

The emerging signal seems consistent: whether in cards or markets, success at Jane Street seems to depend on mastering incomplete information and playing the odds better than everyone else.

Whether coincidence or simply culture, the connection to the dynamics of crypto markets — where information asymmetry, speed, and liquidity positioning determine outcomes — now seems hard to miss.

Whatever the true agenda, the Terra complaint inadvertently lifts the veil on such practices. This is important because they are rarely described in public, despite the dominance of players like Jane Street.

Most of all, it implies that “edge” for many of these players stems less from fancy arithmetic and calculus, and far more from proximity, privileged insight, and narrative positioning — including by shaping the informational environment itself, not merely analysing it. That is, of course, if it is proven at court.

According to Bloomberg, Jane Street firmly rejects the allegations and has described the suit as “desperate” and “a transparent attempt to extract money.”

We will also be seeking comment from Jane Street and will update this piece promptly should a response be provided.
