Physical vs Synthetic ETF Replication Explained

Physical ETFs directly hold the underlying securities. Synthetic ETFs use total return swaps with a counterparty bank. Most ETFs available to Singapore retail investors use physical replication. Key difference: physical ETFs have no counterparty risk but face dividend withholding taxes; synthetic ETFs have lower tracking error but introduce counterparty risk.

Physical ETFs: Pros and Cons

Pros: Transparent holdings; no counterparty risk (securities segregated from manager); dividends collected and reinvested or paid out. Preferred by MAS-regulated platforms.
