How it's calculated

Maintenance ratio = market value of margin-bought stock ÷ total margin balance × 100%

Estimated from TWSE-listed margin data; differs from the TWSE's official 'collateral maintenance ratio' (the statutory measure). The 130% margin-call threshold applies to individual accounts, not this market-wide figure.

The 130% margin-call threshold applies to an individual account's collateral maintenance ratio — this market-wide aggregate is context only; approaching 130% does not mean market-wide forced liquidation.

What is the market-wide margin maintenance ratio?

The margin maintenance ratio measures how much cushion the market value of margin-bought stock holds over the loans behind it. At the market level, the total market value of TWSE margin-bought stock is divided by the total margin balance, giving a read on the pressure facing leveraged money: a falling ratio means margin traders' holdings are shrinking and forced-selling pressure is building; a rebound means the pressure is easing.

What does the 130% margin-call threshold mean?

When an individual account's collateral maintenance ratio falls below 130%, the broker issues a margin call; failing to top up in time triggers forced liquidation. 130% is the statutory threshold for an individual account — the market-wide aggregate is for tracking trends and relative levels, and approaching 130% does not mean market-wide forced liquidation.

Is this the same as the TWSE's official ratio?

No. The TWSE's official figure is the 'collateral maintenance ratio' (the statutory measure, collateral included); this page estimates the ratio from TWSE-listed margin data (source: FinMind). The two differ in level, but their trends can be read against each other. The TWSE has suspended daily publication of the official figure since 2026/07/29; this page's estimate continues to update daily.
