China stock market margin debt hits record $431 billion, topping 2015 peak by 22%

The borrowing surge has doubled over two years and exceeded the roughly $354 billion level reached during China’s 2015 stock market bubble.

Fact Check
Caixin Global (May 12, 2026) confirms margin financing balance at a record 2.83 trillion yuan (~$416B), already well past the 2015 peak of 2.27 trillion yuan (~$354B at 2015 FX). The Kobeissi Letter's claim of ~$431B on June 8, 2026 is a natural extension of that trajectory and the 22% premium over the 2015 peak (354 × 1.22 ≈ 432) is mathematically consistent. Bloomberg and Reuters corroborate the doubling-over-two-years framing from the September 2025 baseline of $320–322B.
Summary

China’s stock market margin debt has climbed to a record roughly $431 billion, a level that has doubled over the past two years and now stands 22% above the roughly $354 billion peak seen during the 2015 Chinese stock market bubble. The figures point to a sharp rise in leveraged equity trading, where investors borrow money to buy stocks and amplify gains or losses. The source also indicates margin trading volume is rising, but the statement is incomplete and does not provide the remaining details needed to verify that point.
