What the MPC actually decides — and the rate it does not set

The two things the committee votes on

India's Monetary Policy Committee decides one number and one sentence. The number is the repo rate — what banks pay to borrow overnight from the central bank against government securities. The sentence is the stance, which carries no number at all.

Both are votes, taken by a committee rather than by the Governor alone. Its members are split between the central bank and appointees from outside it, the Governor chairs it, decisions go by majority, and a tie is broken by the Governor's casting vote. The minutes are published on a fixed lag, and they name each member and record how they voted. That last detail is not procedural trivia — a published dissent is information about how divided the committee was, and it exists precisely so that the decision is not a black box.

The committee is not choosing freely. It works to an inflation target set for it: a numerical rate with a tolerance band either side, notified by the central government in consultation with the RBI and reviewed on a fixed cycle. The target is written on consumer price inflation — the prices households actually face, not wholesale prices and not a stripped-down core measure. Growth is a stated consideration in the statute, not a second target with its own number.

The band is the part most coverage flattens. A target with a tolerance band is not an instruction to hit a point. It is an instruction to keep inflation inside a range, and the Act only deems the target missed when average inflation sits outside that range for a specified run of consecutive quarters — at which point the RBI must report to the government on why it happened, what it proposes to do, and how long it expects that to take. A reading inside the band is not a failure and is not, on its own, a reason for anything.

The corridor: three official rates, and a fourth that actually binds

The repo rate is not itself the price of money in the system. It is the midpoint of a band, and the edges of that band are two standing arrangements the RBI runs on either side of it — windows through which a bank can always lend cash to the central bank or borrow it, whatever the market is doing that day. Those windows are the liquidity adjustment facility, and the band their rates define is the LAF corridor.

Below the repo sits the floor: the rate the central bank pays a bank to park surplus cash with it overnight. For a long time that job was done by the fixed-rate reverse repo, which absorbs cash against collateral. It is now done by a standing deposit facility, which absorbs cash without collateral — the distinction matters, because a central bank that has run short of securities to hand over cannot operate a collateralised floor at scale. The reverse repo is retained as a tool; it is not the operative floor.

Above the repo sits the ceiling: the marginal standing facility, at which a bank short of cash can borrow overnight against government securities it is otherwise required to hold. It is priced above the repo on purpose. A bank drawing on it is paying more than the policy rate for cash it could not raise more cheaply anywhere else, which is what makes it a last resort rather than a funding channel.

Now the question that the whole article turns on. Which of those three rates decides what money costs? None of them directly. Banks do park surplus at the floor and draw at the ceiling, but the bulk of overnight funding is banks lending to each other in the money market, and the rate they agree there is the framework's operating target — the number the RBI is actually steering. The corridor sets the boundaries; liquidity decides where inside the boundaries the market settles.

Here is the arithmetic, and it is illustrative rather than a description of any particular day. Take a symmetric corridor of half-width d, so the floor sits d below the repo and the ceiling d above. When the system is in heavy surplus, banks collectively have cash to place and nowhere better to place it, so the overnight rate drifts down towards the floor. When the system is in deficit, banks are bidding for cash and the rate is pushed up towards the ceiling. Between those two states the overnight rate can travel the full width of the corridor — 2d — without a single vote being cast.

That is the first thing worth taking away. Easing and tightening can both be delivered without a vote, by adding or draining cash rather than by a resolution — the design permits it, because the corridor is a band and not a point. Open-market purchases of government bonds, repo auctions, the cash reserve ratio and the government's own balance at the central bank all move system liquidity, and none of them is an MPC decision. Watching only the headline repo rate is watching the midpoint of a band while the market moves around inside it.

The stance: a signal with no number attached

The second vote produces a word rather than a figure. The stance describes the direction the committee is leaning — whether it is minded to ease, to hold, or to keep withdrawing support — and it has been expressed over the years as accommodative, neutral, calibrated tightening, or withdrawal of accommodation.

It is voted separately from the rate, which is why the two can diverge. A committee can hold the rate and change the stance, and the split of votes on each can differ. A change of stance without a change of rate is the cheapest thing a committee can do, and that is exactly what makes it informative. It repositions expectations without committing anything, and it costs nothing to reverse.

What a stance is not is a schedule. It tells you something about the committee's reaction function — how it currently reads the balance between inflation and growth, and therefore which way it is more prepared to move if the data gives it room. It says nothing about whether that room appears, and it commits the committee to nothing at the next meeting. Reading a stance as a queue of decisions already taken is a category mistake rather than a small one: an intention is not a forecast, and neither is a forecast available. What a market does with a changed sentence — and why an unchanged rate in changed language can move a curve at all — is a separate mechanism, and it turns on what was already priced rather than on what was said.

There is a second reading of the stance that is easy to miss. Because the corridor section above is true — because liquidity can move the operative rate without a vote — the words the committee chooses and what the liquidity desk is doing are worth reading together. When a committee describes itself as withdrawing accommodation and the central bank is at the same time draining surplus cash, that is one policy expressed twice: once in a sentence and once in operations. They are separate decisions by separate bodies and they need not line up. Only one of the two gets reported.

What the MPC does not decide

The cash reserve ratio, open-market operations, currency intervention and every banking regulation announced on policy day. The committee's remit is the policy rate needed to achieve the target, plus the stance; everything else belongs to the RBI as an institution and is announced in the same statement, which is why the two get conflated.

That last row is the whole subject of a separate article. A change in the policy rate is not a change in what anyone pays; it is a change in what banks pay, and the journey from there to a household's monthly loan instalment — the EMI — or to the rate on its deposit is slow, asymmetric and governed by contract structure rather than by intent. How a rate change reaches you traces that chain, and it is the reason a cut can be real and invisible at the same time.

A domestic mandate with an external constraint

The mandate is entirely domestic: a consumer price index, in India, for Indian households. There is no exchange-rate target in it. And yet the rupee enters the decision, which sounds like a contradiction and is not one.

Follow the chain. India imports most of the crude it burns, and crude is priced in dollars. A weaker rupee therefore raises the rupee cost of the same barrel, and fuel and freight sit inside the basket the target is written on. The currency reaches the mandate through the mandate, not around it. A central bank with no exchange-rate objective still has to care about the exchange rate, because a large enough currency move turns into the very number it is legally answerable for. Crude and the rupee each get their own treatment; what matters here is that they arrive at the policy desk as inflation.

The second link is the rate gap. A global allocator holding rupee assets is comparing them against safe dollar assets, and part of what compensates for the risk is the difference between Indian and US rates. Narrow that gap and the compensation thins. This is a channel, not an outcome — capital responds to a great deal besides carry, and nothing here says what any flow will do — but it means a domestic committee's decision is taken in full view of what another central bank has done, without either following the other. The four routes by which a decision in Washington reaches an Indian share price, this one among them, are set out in the Fed article.

The formal version of this constraint is the old proposition that a country cannot simultaneously run an open capital account, manage its exchange rate and keep an independent monetary policy. It can have two of the three — the impossible trinity. A partially open capital account is what buys the room to have most of the other two at once, and that is the conventional reading rather than a measured quantity.

Now the part that closes the loop with the corridor. Selling dollars to lean against a falling rupee takes rupees out of the banking system. The buyer of those dollars pays for them, and the cash disappears into the central bank's balance sheet. So a currency operation is also a liquidity operation: unless it is deliberately offset, defending the rupee tightens domestic money and pushes the operative overnight rate up inside the corridor — with no vote, no announcement and no change in the repo. The foreign-exchange desk and the liquidity desk are the same balance sheet, and this is the clearest case of the thing this article keeps insisting on: the headline rate is one instrument among several, and it is not always the one doing the work.

Reading this on the Macro page — and why our RBI number is a proxy

FNOTrader's Macro page carries a strip of central-bank cards with the RBI first, each showing a current rate, a recent direction and a one-line note. Three things about that card are worth stating plainly, because all three are easy to mistake for something they are not.

The India number is the call-money rate, not the repo. There is no clean live series for the repo rate itself in the data we source from, so the card reads the India call money rate — the overnight rate banks transact at — and the code labels it as approximating the repo. That is an honest proxy for a good reason: the call rate is the framework's operating target, so when the system is neither in large surplus nor large deficit it sits close to the policy rate by design rather than by coincidence.

And here is the cost of that choice, which is the most useful thing on this page to understand. Everything in the corridor section says the operative rate drifts away from the repo exactly when liquidity is lopsided. So the proxy tracks the repo most faithfully when the liquidity story is boring, and diverges precisely when it is interesting. The error term is not noise — it is the corridor position, which is the thing the headline rate cannot tell you. A gap between our card and the announced repo is a signal about liquidity, not a bug in the feed.

The Hiking / Cutting / On hold label is computed, not quoted. The page derives it from the change in that series over roughly the past three months, with a small dead band so that a negligible move reads as On hold. It is our summary of where a rate has been. It is not the MPC's published stance, which is a forward-facing vote about intent and can point the opposite way to the last three months of a rate series without either being wrong. Two different things wearing the same word.

The series is monthly, so the card lags. A monthly observation cannot show you a corridor that moves daily, and it will not reflect a decision taken since the last print. For anything time-sensitive the card is context, not a live rate.

One structural point to close on. No Indian policy rate appears among the weighted tiles at all. The composite score is a weighted average, score = 100 × Σ(w_ic_i) ÷ Σ(w_i), over twenty tile inputs whose weights sum to 1.33 — the dollar index at 0.20 and the US 10-year yield at 0.15 the largest of them — plus foreign portfolio flow, which is not in the tile table and is folded in at scoring time at 0.12, saturating at ±₹5,000 crore. Twenty-one inputs, then, and a divisor of 1.45 on a day when every feed reports. When a feed fails, its weight leaves the numerator and the denominator together, so the divisor falls with it — 1.45 is the all-present maximum, not a constant.

Those weights, and the regime boundaries at ±20, are FNOTrader's modelling judgement about what matters most to Indian equities — a considered view, not a measured constant and not a fitted coefficient. India enters that score through India VIX, the rupee and foreign flows. The central-bank strip sits outside it entirely, and reporting a policy rate is all it does.

Four ways this gets misread

Watching the repo and nothing else. The headline rate is the midpoint of a band. If the system swings from surplus to deficit, the money market reprices by up to the corridor's full width with the midpoint unchanged. Anyone tracking only the announced number has, on such a stretch, missed the entire move.

Reading a stance as a schedule. A stance is a description of how the committee is currently weighing things, published so the decision is legible. It is not a queue of decisions already taken, and treating it as one converts an intention into a forecast that nobody made.

Assuming a cut has reached anyone. A policy rate change moves what banks pay. What a household pays moves later, by a different amount, and at different speeds on the borrowing and the deposit side — the mechanism is contract structure, and it is set out in the transmission article. Between the vote and the EMI there is a benchmark, a reset date and a bank's own pricing decision.

Treating the RBI as a follower of the Fed. The rate gap is a real constraint and it runs through the rupee, which runs through imported inflation, which is inside the mandate. That is a channel with several links in it, and a channel is not a rule. A domestic committee working to a domestic index can move less than, more than, or opposite to another central bank over any given stretch, and the gap tells you where the pressure is rather than what anyone will do about it.

What to read on the day, if the point is to understand the decision rather than to react to it: the resolution for the rate and the stance, the minutes for the votes and the dissents, and the liquidity operations for what is happening to the rate that actually binds. The wider set of tiles and how they are meant to be read together is the subject of the macro pillar. This article is the long version of one card.
