Low-Rate World
A low-rate world is an environment where the risk-free rate is so low that prospective returns fall across nearly all assets. Marks treats this as the dominant post-2020 condition before the later sea change: prices can look expensive in absolute terms and still look coherent relative to near-zero rates.
Mechanism
- Lower discount rates raise present values.
- Safe bonds become weak competitors for capital.
- Investors are pushed out the risk curve.
- Capital markets reopen easily because financing is cheap.
- Expected returns fall even when prices feel justified.
The uncomfortable result is that assets can be expensive, future returns can be mediocre, and yet the relative comparison can still make them look hard to avoid.
Why This Is Behaviorally Dangerous
A low-rate world can make disciplined investors feel trapped. They may be correct that assets are expensive and still feel compelled to own them because the alternatives are even less attractive. That makes the regime dangerous not only because of valuation but because it normalizes weak future return assumptions.
Main Risk
The whole structure depends on rates staying low. If inflation or policy shifts force higher demanded returns, asset prices can fall sharply. That is why this concept naturally leads into sea-change-in-rates.
