TL;DR

This paper analyzes the 2022 collapse of FTX, a major centralized cryptocurrency exchange, by examining on-chain data, market dynamics, and social media activity. It reveals that FTX’s reliance on its own non-collateralized token (FTT) as synthetic collateral created a fragile, opaque leverage mechanism, which collapsed after the Terra-Luna crash and was accelerated by Binance’s public liquidation announcement, highlighting systemic risks in centralized digital finance and the urgent need for genuine decentralization in crypto.

ABSTRACT

This paper investigates the causes of the FTX digital currency exchange's failure in November 2022. We identify the collapse of the Terra-Luna ecosystem as the pivotal event that triggered a significant decrease in the exchange's liquidity. Analysing on-chain data, we report that FTX heavily relied on leveraging and misusing its native token, FTT, and we show how this behaviour exacerbated the company's fragile financial situation. To gain further insights into the downfall, we study evolutionary dependency structures of 199 cryptocurrencies on an hourly basis, and we investigate public trades at the time of the events. Results suggest that the collapse was actively accelerated by Binance tweets causing a systemic reaction in the cryptocurrency market. Finally, identifying the actors who mostly benefited from the FTX's collapse and highlighting a generalised trend toward centralisation in the crypto space, we emphasise the importance of genuinely decentralised finance for a transparent, future digital economy.

Motivation & Objective

• To investigate the root causes of FTX’s failure in November 2022, focusing on its financial structure and reliance on its native token, FTT.
• To analyze the systemic impact of the Terra-Luna collapse on FTX’s liquidity and balance sheet integrity.
• To examine how Binance’s public announcement of liquidating FTT reserves acted as a catalyst for FTX’s final collapse.
• To assess the broader trend of centralization in the crypto market post-FTX, particularly Binance’s market share expansion.
• To advocate for decentralized finance (DeFi) as a transparent, accountable alternative to opaque, centralized crypto institutions.

Proposed method

• Utilized three heterogeneous data sources: hourly closing prices, on-chain transaction data, and public trade data from exchanges.
• Tracked the evolutionary dependency structure among 199 cryptocurrencies using network science techniques to model market contagion effects.
• Analyzed on-chain data to quantify FTX’s and Alameda Research’s ownership of 80% of FTT supply and their use of FTT as uncollateralized collateral.
• Mapped the timeline of events using public reports (e.g., CoinDesk’s FTT exposure disclosure) and social media activity (e.g., Binance’s Twitter announcement).
• Measured market concentration through exchange-reserve holdings and market capitalization trends of top stablecoins (USDT, USDC, BUSD, DAI) from January to December 2022.
• Applied rescaling and visualization techniques to assess shifts in stablecoin supply and market cap, identifying centralization trends.

Experimental results

Research questions

• RQ1 What role did the Terra-Luna collapse play in triggering FTX’s liquidity crisis and subsequent failure?
• RQ2 How did FTX’s reliance on its non-collateralized native token (FTT) as a form of synthetic collateral contribute to systemic fragility?
• RQ3 To what extent did Binance’s public announcement of liquidating FTT reserves act as a catalyst for FTX’s final collapse?
• RQ4 How did the FTX collapse accelerate the centralization of the crypto market, particularly through Binance’s increased market share?
• RQ5 What are the implications of centralized, unregulated crypto exchanges for the long-term viability of a transparent, decentralized digital economy?

Key findings

• The collapse of the Terra-Luna ecosystem in May 2022 triggered a significant decline in FTT’s price and reduced credit availability, directly impacting FTX’s liquidity.
• FTX and Alameda Research held 80% of the total FTT supply, enabling them to manipulate the token’s price and use it as uncollateralized collateral for leveraged borrowing.
• CoinDesk’s report on November 2, 2022, revealing Alameda’s $6 billion FTT exposure, exposed the fragile leverage mechanism and triggered a market panic.
• Binance’s public announcement on November 6, 2022, to liquidate all FTT holdings on its exchange acted as the final catalyst, accelerating FTX’s insolvency and leading to its bankruptcy on November 11.
• Binance’s market share rose from 48.7% in Q1 2022 to 66.7% in Q4 2022, indicating a significant market consolidation following FTX’s failure.
• The FTX collapse underscores the risks of centralized, opaque financial entities in crypto, reinforcing the need for genuine decentralized finance (DeFi) to ensure transparency, self-custody, and governance.
