Interest Rates and How They Move Asset Prices
Key takeaways
- Interest rates determine the cost of borrowing money and indirectly affect the value of equities, bonds, and real estate.
- Rising rates make financing more expensive, reduce the present value of future earnings, and push bond prices down.
- Falling rates have the opposite effect — they support asset prices and stimulate the economy.
- For the long-term investor, rates are macroeconomic context, not a signal to buy or sell.
- A diversified portfolio is the most robust response across different phases of the rate cycle.
Interest rates are the price of money over time — and because money flows through the entire economy, their level affects almost every asset class, from equities and bonds to real estate.
How Rates Affect Bonds
The relationship is direct and inverse: when rates rise, prices of existing bonds fall, because newly issued bonds offer higher coupons. Holders of older bonds see their market prices decline. Conversely — when rates fall — bond prices rise. That is why equity holders also pay attention to rate movements: they affect the discount rate used to convert future earnings to their present value.
How Rates Affect Equities
Rising rates make credit more expensive for companies, compress the margins of heavily indebted firms, and make risk-free instruments (government bonds) more attractive. The result is downward pressure on equity valuations — especially for growth companies whose earnings lie far in the future. Conversely, falling rates reduce the discount factor and support valuations. More on valuations in the context of active vs. passive investing.
Real Estate and Rates
Higher rates make mortgages more expensive, reduce housing affordability, and can dampen prices. In the Czech Republic, the mortgage market is sensitive to movements in the CNB rate and long-term yields. However, local supply, demand, and regulation all play a role — rates alone don't capture the whole picture.
What This Means for You as an Investor
- Rates are part of the macroeconomic context, not a trading signal.
- A long-term investor holds a diversified portfolio and sticks to the plan regardless of the current rate level.
- Rebalancing and regular contributions are stronger tools than tactical moves based on central bank announcements.
FAQ
Why do rising rates push bond prices down?
Because newly issued bonds at higher rates offer higher yields. Older bonds therefore become less attractive and their market price falls until their yield matches the current market level.
Should I sell equities when the central bank raises rates?
Generally no. Markets price in rate moves in advance, and the portfolio reaction is complex. Selling in response to macro news is a costly strategy — a long-term investor sticks to the plan.
How can I protect my portfolio from the impact of rates?
Through diversification across asset classes — equities, bonds, different geographies. No single asset class responds to rates in the same way, which makes diversification sensible throughout the entire rate cycle.
