Policy rates change the discount, not just the mood
When a central bank changes its policy rate, the mechanical effect is on discount rates and on the price of time. Narratives about confidence come second. This note follows the mechanical path.
What is going on
Bond yields move with expected policy and with term premium. Equity valuations are claims on cash flows discounted at rates that embed those yields and a risk premium. Currency rates embed interest differentials. These links are taught because they are real, and they are unstable because risk premiums move at the same time as the cash rate. A cut is not a universal buy signal. A hike is not a universal sell signal.
Why it matters
The practical effect for an individual investor is simpler than the narrative. Cash and short bonds start to pay something, or stop paying. Borrowing costs on margin change. The hurdle for a risky project rises or falls. Anyone using leverage feels the change in the financing line, not only in the index.
What to watch
Watch the path implied by short-term interest-rate markets and the central bank’s own projections, and treat both as prices and plans, not as destiny. The economic calendar on this site will show releases only when a sourced feed is connected.
Risks
Discount-rate stories can be overwhelmed by earnings, by politics and by liquidity squeezes. A correct textbook link can be the wrong trade.
