Smart Way to Create Cash Flow: The 'Bond Windmill Strategy' for Small Investors | Gu Hye-young, Yeo Do-eun, Heo Jae-mu

Summary

Bond analyst Gu Hye-young makes the case for a prolonged medium-rate environment driven by AI infrastructure, defense spending, and sticky inflation. She argues that investors should abandon hopes of capital gains from falling rates and instead use a 'bond windmill strategy'—laddering bonds with short maturities to harvest high coupon income. Brazilian local government bonds (10% coupon, tax-free, tiny minimum) and Korean 10-year government bonds (4.25%) are both viable vehicles for this approach, creating reliable cash flow pipelines even for small investors.

• Guest Gu Hye-young explains the structural forces (AI capex, new Cold War, fiscal spending) that will keep interest rates in a medium 3–5% range for years.
• She urges investors to shift focus from bond capital gains to building cash flow through carry.
• The 'bond windmill strategy' is introduced: buy bonds with staggered short maturities to generate regular interest income and principal returns.
• Brazilian local government bonds are highlighted: 10% annual coupon, completely tax-free, and available in contracts as low as KRW 200,000–250,000.
• Korean 10-year government bonds also offer an attractive 4.25% coupon, far above bank deposit rates, making them suitable for laddering.
• The flat yield curve reinforces the approach—longer maturities do not provide much extra yield, so staying short and rotating is efficient.
• Investors can choose between taking cash flow as income or continuously reinvesting maturing principal to compound returns.
• The strategy is positioned as a way for retail investors to access bond cash flow that was previously only feasible for high-net-worth individuals.
