How the RBI sets the rate, what transmission is, and which sectors move first
Published by The Retail Trader · AUG 09, 2026 · Features
Every few months there is a meeting, after which one number comes out, and the next day every business channel talks about it. That number is the repo rate, and its path runs from your home loan all the way to your portfolio.
The repo rate is the rate at which banks borrow short-term money from the RBI. It becomes the reference for the cost of money across the whole system.
The decision is made by the Monetary Policy Committee, whose mandate is to keep inflation within a set band — keeping growth in mind. So the rate decision does not look at inflation alone or growth alone; it looks at the balance of the two.
A change in the rate does not take effect immediately. Banks change their deposit and lending rates slowly, and the reset of older loans happens on its own cycle.
So 'the rate was cut, now the EMI is lower' does not happen right away. Loans linked to an external benchmark change quickly, others slowly. This lag is why it takes months for the full effect of policy to show.
Those with the most direct link to the rate:
• Banks and NBFCs — their whole business is the cost of money. The effect on margins is direct, but the direction is not always simple.
• Real estate and auto — demand that runs on EMIs. When rates fall, the mood of demand improves.
• Capital-heavy companies — those with large borrowings see their interest cost rise and fall directly.
• IT and exporters — they are driven more by currency and global demand than by the rate, so the effect of the domestic rate is less direct.
When rates fall, the present value of future earnings rises — this is why long-growth stocks look more expensive in cheap-rate times and are also forgiven for that expense.
When rates rise, the opposite happens: the present value of distant earnings falls, and those same stocks are the first to correct. This is not the story of any one company — it is the discount rate of the whole market changing.
The immediate reaction on policy day is often reversed or incomplete, because the market has already priced in a large part of the decision. The more useful thing is not the rate number — it is the governor's statement and the tone going forward.
So on policy day, reading the commentary that accompanies the headline is more informative than the headline itself.
