Margin debt to another record high

FINRA margin debt (aka debit balances in customers' securities margin accounts) reached a new record high of $1.214 trillion in November, marking its sixth consecutive record high since crossing above the $1 trillion threshold in June. The late 2021 to mid 2025 cup and handle pattern supports the case for margin debt to reach $1.260 trillion.

The surge in margin debt reflects growing risk appetite and investor confidence, but investors worry that it points to outright euphoria, which is a contrarian bearish signal. Similar concerns about speculative excess surfaced between 2013 and 2018 as both margin debt and the SPX consistently rose to new all-time highs.

Historically, margin debt tends to rise with equities, supporting bullish trends rather than derailing them. The real risk comes when leverage starts to unwind.

We would worry if margin debt declined while the SPX rallied, a pattern that preceded market peaks followed by corrections and/or bear markets in 2000, 2007, 2018, 2019, and late 2021.
