What Is 公債殖利率（Treasury Yield）?
10年期公債殖利率是房貸利率的風向標。當公債殖利率上升，房貸利率通常跟漲，融資成本增加；下降時則融資環境寬鬆。投資者應關注殖利率的趨勢而非短期波動——持續上升的趨勢意味著鎖定固定利率可能更明智，而下降趨勢則可能預示再融資窗口的開啟。
公債殖利率（Treasury Yield）是美國公債的年化報酬率，尤其是10年期公債殖利率，被廣泛視為無風險利率的基準，直接影響房貸利率和房地產融資成本。

How It Works
Core mechanics. Treasury Yield operates within the broader framework of economic fundamentals. When investors encounter treasury yield in a deal, they need to understand how it interacts with other variables like operating expenses, NOI, and cap rate. The concept applies whether you are analyzing a single-family rental or a small multifamily property.
Practical application. In practice, treasury yield shows up during the research phase of investing. For properties in markets like Indianapolis, understanding this concept helps you make informed decisions about pricing, financing, or management. Most investors learn to factor treasury yield into their standard deal analysis spreadsheet alongside metrics like cash-on-cash return and DSCR.
Market context. Treasury Yield can vary significantly across markets. What works in Indianapolis may not apply in a coastal metro where cap rates are compressed and competition is fierce. Always validate your assumptions with local data and comparable transactions.
Real-World Example
Ava is evaluating a property in Indianapolis listed at $312,000. The property generates $2,400/month in gross rent across two units. After accounting for treasury yield in the analysis, Ava discovers that the effective return shifts meaningfully — the initial 6.7% cap rate calculation changes once this factor is properly accounted for.
Ava runs the numbers both ways: with and without properly accounting for treasury yield. The difference amounts to roughly $3,200/year in either additional cost or reduced income. On a $312,000 property, that is the difference between a deal that meets the 1% rule and one that falls short. Ava adjusts the offer price accordingly and negotiates a $12,000 reduction, which the seller accepts after 8 days on market.
Pros & Cons
- Helps investors make more accurate deal projections by accounting for a commonly overlooked variable
- Provides a standardized framework for comparing properties across different markets and property types
- Reduces the risk of unpleasant surprises after closing by identifying potential issues during due diligence
- Gives experienced investors an analytical edge over less sophisticated buyers in competitive markets
- Can add complexity to deal analysis, especially for newer investors still learning the fundamentals
- Market-specific variations mean that rules of thumb may not apply universally across all property types
- Requires access to reliable data, which can be difficult to obtain in some markets or property categories
- Over-optimizing for this single factor can cause analysis paralysis and missed opportunities
Watch Out
- Data reliability: Always verify your treasury yield assumptions with actual market data, not seller-provided projections or outdated estimates
- Market specificity: Treasury Yield behaves differently in landlord-friendly vs. tenant-friendly states, and across different property classes
- Integration risk: Do not analyze treasury yield in isolation — it interacts with financing terms, tax implications, and local market conditions
