Margin Trading in Japan: Two Systems

• Exchange-Regulated Margin (制度信用)
  • Rules set by Japanese stock exchanges (e.g., Tokyo Stock Exchange).
  • Standard settlement term: 6 months.
  • Trading conditions (collateral ratio, margin calls) are standardized.
• General Margin (一般信用)
  • Rules set by individual brokers.
  • Terms vary: may be short-term (few days) or no fixed term.
  • Trading costs (interest, fees) and conditions differ by broker.
• This dataset separates both systems, enabling detailed analysis of investor behavior.

Notes

• Margin ratios are dimensionless (often described as “x倍” in Japanese).
• In the unlikely case where the denominator (short balance) would be 0, the ratio is computed using 1 instead of 0 to avoid division errors. However, for Nikkei 225 constituents, such cases are practically nonexistent.
• This dataset covers Nikkei 225 constituents only.
• All figures are unadjusted for corporate actions (e.g., stock splits, reverse splits).
  This applies to all data fields, including stock prices, margin balances, trading volume, and turnover.
