TWSE Block Trade in Taiwan

Taiwan Stock Exchange is the principal cash-equity venue of Taiwan. Founded in 1962, it operates under the oversight of Financial Supervisory Commission (FSC), and its leading benchmarks are TAIEX, FTSE TWSE Taiwan 50. Listing standards are set out in the TWSE Operating Rules; Securities and Exchange Act.

TWSE at a glance:

Taiwan’s principal equity venue, heavily concentrated in semiconductor and electronics names — a single issuer accounts for a large share of TAIEX capitalisation. Foreign institutional flows drive much of the day-to-day liquidity that shapes eligibility.

On TWSE, block trades run to defined size thresholds and a fixed reporting rhythm: a securities firm reports the transaction to the exchange on trade day, and the exchange publishes a daily block-trading summary of single-security and paired trades. Trades can be routed through an omnibus trading account, where the account rather than each underlying investor meets the size requirement. Settlement is T+2. For a controlling-shareholder line, the practical read is that a negotiated block prices the whole position at once, off the continuous book, rather than exposing it to intraday depth in a market where turnover concentrates in a few large-cap names.

The principal regulatory reference on TWSE is Securities and Exchange Act Art. 43-1. How it applies to any single transaction — reporting levels, step thresholds — turns on the underlying rules and national-law overlays, which we map against your contemplated transaction at the structuring stage alongside the counsel you appoint.
