The narrowing of the excess return investors demand for holding equities over risk-free assets — a structural driver of equity multiple expansion independent of earnings growth.
“Risk premiums rise when people are fearful and compress when they are comfortable. The irony is that risk is actually highest when the premium is lowest — because that is when assets are most expensively priced relative to their true risk. Understanding this inversion is essential. — Ray Dalio”

Deeper Explanation
The Equity Risk Premium (ERP) is the additional annual return investors require for bearing equity risk compared to a risk-free asset (the 10-year G-sec yield in India). When ERP is elevated — during periods of fear, uncertainty, or recession — equity multiples are compressed: investors pay less per rupee of earnings because they demand a larger buffer. When ERP compresses — as confidence grows, volatility falls, and monetary policy is accommodative — equity multiples expand, sometimes dramatically, even without any improvement in underlying earnings. ERP compression is a major driver of bull markets that is often misattributed entirely to earnings growth. India's implied ERP has ranged from approximately 4% to 9% across full cycles. Periods of ERP compression (FY2014–18, FY2020–22) generated significant multiple expansion even with modest earnings growth. Periods of ERP expansion (FY2008, FY2013, FY2022) produced sharp multiple compression even where underlying corporate profits held up. Understanding ERP explains two otherwise puzzling phenomena: why 'expensive' markets continue to rise (ERP is still compressing), and why 'cheap' markets continue to fall (ERP is still expanding). The ERP is the macro valuation variable that connects monetary policy, credit conditions, and investor psychology into a single number that explains equity multiples.
