US bond ETFs gain extra yield via European Irish UCITS structures
Irish domiciled UCITS ETFs reinvest US Treasury semi-annual coupons internally, avoiding withholding taxes and compounding returns over seven years.
Investors in the United States can now access European Union Investment Company Undertakings (UCITS) funds registered in Ireland or Luxembourg to hold US Treasury bonds with enhanced tax efficiency. These ETFs differ from US-listed funds by automatically reinvesting semi-annual interest payments back into the fund rather than distributing them to shareholders. This mechanism prevents immediate withholding tax on distributions, allowing compounding of returns without cash flow interruptions. A simulation by XP Investments indicates that a seven-year investment of US$100,000 in an accumulation-based UCITS ETF would generate an additional US$7,560 compared to a standard US-listed ETF under similar conditions. The strategy gains relevance amid rising US Treasury yields, which have reached levels approaching 20 years as geopolitical tensions and inflation concerns drive long-term bond prices lower. Market volatility surrounding the conflict between the United States and Iran, specifically regarding the Strait of Hormuz, continues to support crude oil prices and fuel inflationary pressures. Consequently, US fiscal uncertainty and increased debt issuance have impacted yields on longer-dated bonds. To mitigate escalation risks, the US Treasury Department doubled its repurchase program size for long-term securities in August, while the Federal Reserve keeps options open for further interest rate increases.
