A central bank's mandate is its constitution, the objective the law hands it. Because the tools are broadly similar across countries, the mandate is the single biggest thing that differs and the first thing an analyst should know about any central bank. Three matter for this program; a fourth is worth awareness.
What is the Fed's dual mandate?
The Federal Reserve: the dual mandate. US law (the Federal Reserve Act, as amended in 1977) instructs the Fed to promote "maximum employment, stable prices, and moderate long-term interest rates." In practice this is read as a dual mandate: maximum employment and price stability, treated as co-equal. Two consequences follow. First, the Fed will tolerate being away from its inflation target for longer if employment is weak, and will actively try to cool a red-hot labour market even when inflation looks fine. It has two targets, not one, and must trade them off. Second, "price stability" has been given a number: since 2012 the Fed has defined it as 2% inflation, measured by the PCE (personal consumption expenditures) price index. Note, not CPI; the Fed's preferred gauge is PCE, which typically runs a few tenths below CPI (M7.03 dissects the difference). The Fed's framework has itself evolved: in 2020 it adopted flexible average inflation targeting (FAIT), promising to let inflation run moderately above 2% for a time to make up for past shortfalls; after the 2021–23 inflation, the Fed's 2025 framework review revisited and pared back that language (check the current framework statement at federalreserve.gov; this is exactly the kind of thing that changes and that you should never quote from memory).

What is the ECB's price stability mandate?
The European Central Bank: price-stability primacy. The ECB's mandate (Treaty on the Functioning of the EU) is lexicographic, not dual: its primary objective is price stability, and only "without prejudice" to that may it support the EU's broader economic goals. Price stability is defined (since the 2021 strategy review) as a symmetric 2% inflation target over the medium term, measured by the HICP (harmonized index). The primacy matters: an institution told that price stability comes first, full stop, behaves differently in a growth scare than one holding a dual mandate. That is part of why the ECB was slower to ease than the Fed in some episodes, and why the euro-area's structural growth problems are, by design, not the ECB's job to fix.
How does the RBI's flexible inflation targeting work?
The Reserve Bank of India: flexible inflation targeting. India adopted a formal inflation-targeting framework only recently, and it is worth knowing the mechanism because it is examined and because it is genuinely well-designed. Under the amended RBI Act, the Government of India, in consultation with the RBI, sets a numerical inflation target every five years. The current target: 4% headline CPI, with a tolerance band of ±2% (i.e., 2% to 6%). Mark this "verify," because the framework is up for its five-yearly renewal around 2026 and the numbers could change; pull the current target from the RBI's Monetary Policy Framework page. Three design features to hold:
- It is flexible inflation targeting ("FIT"): the RBI targets 4% CPI but is explicitly allowed to look through temporary shocks and to weigh growth; the word "flexible" is what keeps it from being a single-minded inflation machine. The primary target is inflation; growth is a secondary consideration, not a co-equal one as at the Fed.
- It targets headline CPI (the whole basket, food and fuel included), not core. That is a deliberate and much-debated choice, because Indian households experience food inflation viscerally and inflation expectations are set by the vegetables-and-fuel prices households actually see (M7.03).
- There is a hard accountability clause: if average CPI inflation breaches the 2–6% band for three consecutive quarters, the RBI is deemed to have failed and must write a formal letter to the government explaining why, what it will do, and how long the fix will take. This actually happened in 2022. The clause is what gives the target teeth.
How do the FOMC and the MPC vote?
The decision bodies: how the vote actually works (this is what you read on decision day):
| Feature | US — the FOMC | India — the MPC |
|---|---|---|
| Full name | Federal Open Market Committee | Monetary Policy Committee |
| Members | 12 voting: 7 Board Governors + NY Fed president (permanent) + 4 of the other 11 regional presidents (rotating yearly) | 6: 3 from the RBI (Governor as chair, the Deputy Governor for monetary policy, one RBI officer) + 3 external members appointed by the government |
| Chair / tie-break | Fed Chair; consensus-driven, dissents noted | RBI Governor chairs and has a casting (second) vote in a tie |
| Meetings/year | 8 scheduled | at least 4 (in practice 6, bi-monthly) |
| Vote disclosed? | Yes: each member's vote and dissents in the statement/minutes | Yes: each member's vote and rationale in the minutes (released ~14 days later) |
| Signature extra | The SEP + dot plot (quarterly): each member's projection for growth, unemployment, inflation, and the appropriate policy-rate path | The Governor's statement + the bi-annual Monetary Policy Report; RBI publishes its own growth and inflation projections |
The structural point for an analyst: both are committees, both publish the split, and the split is information. A 4–2 MPC vote to hold, with two members dissenting for a cut, tells you the next move's direction and that it is close. That is worth more than the decision itself. The composition also matters: the government appoints three of the RBI's six MPC members (and the Governor), which is the concrete channel through which the independence question (see central bank independence) becomes real rather than abstract.
Why is the Bank of Japan an outlier?
Awareness: the Bank of Japan. Worth knowing as the great outlier: the BOJ spent roughly 1995–2024 fighting deflation, not inflation, holding rates at or below zero, pioneering QE (the term was coined for the BOJ in 2001) and yield-curve control (pinning the 10-year JGB yield directly), before finally exiting negative rates in 2024 as inflation returned. Japan is the standing reminder that the enemy is not always inflation. Sometimes it is the far more dangerous problem of prices and wages that will not rise (M7.05's balance-sheet recession), and the toolkit has a very different feel when you are pushing on a string.
