Updated for the 2026-2027 CFA® Level I curriculum.
Central banks do not manage the economy directly. They manage a target variable and rely on that variable to transmit policy through the economy. This note compares the three main monetary policy objectives tested at Level I: inflation targeting, interest-rate targeting, and exchange-rate targeting. You need to identify which target a central bank is using and predict how it responds to a shock.
Quick Answer
A policy target is the variable a central bank commits to influence in order to achieve its broader mandate. Inflation targeting anchors expectations to a stated inflation rate or band.
Interest-rate targeting manages a short-term rate as the operating instrument for policy. Exchange-rate targeting fixes or manages the currency against a reference currency.
Each regime supports one monetary policy objective directly, but defending that target can limit a central bank's ability to pursue other objectives, especially when capital moves freely across borders.
Key Takeaways
Inflation targeting uses a published inflation rate or band as the nominal anchor and adjusts policy based on inflation forecasts.
Interest-rate targeting uses a short-term rate, often an overnight rate, as the operating instrument, not the ultimate objective.
Exchange-rate targeting commits the central bank to defend a currency level, usually through interest-rate moves and reserve intervention.
A nominal anchor is the variable that pins down inflation expectations and gives the regime credibility.
Credibility and clear communication affect how quickly each regime works and how much output volatility it causes.
Defending one target can conflict with domestic objectives, particularly under exchange-rate targeting with open capital markets.
Easing or tightening decisions look different under each regime, even when the economic shock is the same.
What You Need to Know for CFA Level I
Identify the target type from a central bank statement, mandate, or policy action.
Explain the operating logic and information requirements behind each regime.
Compare the three targets on credibility, flexibility, transparency, reserve needs, and policy autonomy.
Connect a given economic shock to the expected easing or tightening action under each target.
Keep exchange-rate regime classification and central bank mandate detail out of this note; those belong on separate notes.
Inflation Targeting
Inflation targeting sets a numerical inflation rate or band as the nominal anchor, commonly 2% with a tolerance range. The central bank does not react to current inflation alone. It builds a forecast, usually 12 to 24 months forward, and adjusts the policy rate today to hit the target later. This forward-looking process requires a reasonably reliable forecasting model and open communication about the reasoning behind each decision.
Objective | Action | Risk |
|---|---|---|
Keep inflation near the stated target | Raise or lower the policy rate based on the inflation forecast | Forecast errors delay the correct response |
Anchor inflation expectations | Publish target, forecasts, and rate decisions | Weak communication reduces credibility |
Preserve flexibility for output shocks | Allow short-term deviations from target | Repeated deviations without explanation erode trust |
Inflation targeting gives a central bank flexibility to respond to output shocks because it targets an average outcome over time rather than a fixed daily variable. The tradeoff is a longer transmission lag. Markets need to believe the central bank will hit the target, or the anchor loses its effect on expectations.
Interest-Rate Targeting
Interest-rate targeting uses a specific short-term rate, often an overnight interbank rate, as the day-to-day operating target. This rate is the instrument the central bank controls directly through open market operations or standing facilities. It is not the ultimate objective. The ultimate objective is usually price stability or full employment, and the rate target is the tool used to reach it.
Some central banks manage a rate corridor, with a ceiling and floor around the target rate, using lending and deposit facilities to keep the market rate inside the band. The central bank controls the short end of the yield curve closely but has far less direct control over longer maturities, which respond to expectations, term premiums, and credit conditions.
Distinguishing instrument from objective: the policy rate is what the central bank sets. Inflation, output, or employment is what the central bank ultimately wants to influence. Confusing the two is a common exam trap covered below.
Exchange-Rate Targeting
Exchange-rate targeting commits the central bank to hold the currency at or near a specific level against a reference currency, such as a peg or a narrow target zone. The central bank defends this level using two main tools: adjusting the policy rate to attract or repel capital flows, and buying or selling foreign exchange reserves directly.
Defense Mechanism | How It Works | Constraint Created |
|---|---|---|
Interest-rate alignment | Raise domestic rates to defend a weakening currency | Domestic tightening may be needed even if the economy is slowing |
Reserve intervention | Sell foreign reserves to buy domestic currency, or the reverse | Reserves are finite and intervention has a practical limit |
Capital controls (where used) | Restrict outflows to reduce pressure on the peg | Reduces investor confidence and market access over time |
Exchange-rate targeting imports the credibility and inflation performance of the reference currency, which is useful for economies with weak monetary credibility of their own. The cost is a loss of independent monetary policy. If the domestic economy needs easing but the currency is under pressure, the central bank may be forced to tighten instead to defend the peg. This conflict is the central tradeoff tested at Level I.
Comparing Central Bank Policy Targets
Dimension | Inflation Targeting | Interest-Rate Targeting | Exchange-Rate Targeting |
|---|---|---|---|
Nominal anchor | Published inflation rate or band | Policy rate level | Currency level or band |
Flexibility | Moderate, allows short-term deviation | Moderate, rate can move with conditions | Low, target is fixed or narrowly managed |
Transparency | High, requires public forecasts and communication | Moderate | Moderate, target level is public but intervention is discretionary |
Reserve needs | Low | Low | High, reserves back the defense |
Policy autonomy | High | High | Low, especially with open capital markets |
Vulnerability to shocks | Forecast errors, credibility loss | Yield curve control limited beyond short end | Speculative attacks, reserve depletion |
No single target is superior in every environment. Inflation targeting suits economies with reliable data and credible institutions. Exchange-rate targeting suits small open economies seeking imported stability. Interest-rate targeting is the operating mechanism inside most of these frameworks, not a standalone alternative.
Worked Example
Three central banks announce mandates:
Bank A publishes an inflation target of 2%, with a tolerance band of 1% to 3%. Current inflation forecast for next year is 3.6%.
Bank B manages an overnight rate corridor with a target rate of 4.00%, floor at 3.75%, ceiling at 4.25%. Interbank rates have drifted to 4.30%.
Bank C pegs its currency at 8.00 units per US dollar. The currency has weakened to 8.25 and is under continued selling pressure.
Step 1: Identify the target. Bank A uses inflation targeting. Bank B uses interest-rate targeting. Bank C uses exchange-rate targeting.
Step 2: Identify the pressure. Bank A's forecast (3.6%) sits above the tolerance band (3%). Bank B's market rate (4.30%) sits above the corridor ceiling (4.25%). Bank C's currency (8.25) has weakened past the peg (8.00).
Step 3: Identify the likely action. Bank A tightens policy now to bring the inflation forecast back inside the band over the forecast horizon. Bank B intervenes through its facilities, likely tightening liquidity conditions, to pull the market rate back under the ceiling. Bank C raises domestic interest rates and sells foreign reserves to support the currency and defend the peg, even if domestic conditions would otherwise call for easing.
Interpretation: Each bank responds to pressure differently because the variable it defends is different. Bank C's action may conflict with its domestic growth needs. This is the policy autonomy tradeoff the LOS asks you to contrast.
Common Exam Traps
Confusing the instrument with the objective. The policy rate is a tool. Price stability or employment is the goal. A question describing rate changes is testing interest-rate targeting mechanics, not necessarily the ultimate objective.
Treating exchange-rate targeting as free of cost. Pegging a currency does not eliminate tradeoffs. It transfers monetary independence to the reference currency's central bank.
Assuming an inflation target means zero inflation. A 2% target is not price stability at 0%. Deviations within the band are expected and do not always trigger a policy response.
Ignoring credibility and communication. A central bank with low credibility needs a larger policy move to achieve the same effect as one with high credibility. This affects the size, not just the direction, of the response.
Pulling in full exchange-rate regime detail. Classifying pegs, crawling bands, and free floats belongs on the exchange rate regimes note, not here.
Practice Question
A central bank publishes a mandate to keep its currency fixed at 110 units per reference currency. The currency has recently traded at 114 and shows continued depreciation pressure. Domestic unemployment is rising and would normally call for lower interest rates.
Which action is most consistent with the central bank's stated target?
Lower the policy rate to support domestic employment, allowing the currency to depreciate further.
Raise the policy rate and sell foreign currency reserves to defend the peg.
Hold the policy rate unchanged and allow the inflation forecast to determine the next move.
Correct answer: B
Explanation: The central bank's stated target is the currency peg, not domestic employment or inflation. Defending a weakening peg requires raising rates to attract capital inflows and selling reserves to support demand for the domestic currency. This is consistent with exchange-rate targeting even though it conflicts with the domestic employment goal.
Option A. This describes a response consistent with a domestic objective like employment, not the stated exchange-rate target. It ignores the mandate entirely.
Option C. This describes inflation-targeting logic. The bank in this question has not adopted an inflation target, so a forecast-based rate decision is not the correct framework.

FAQs About Central Bank Policy Targets
What are the main objectives of monetary policy?
Central banks pursue price stability and, in many mandates, full employment or stable output. Inflation, interest-rate, and exchange-rate targeting are the three operating frameworks used to pursue those objectives, and each carries different tradeoffs for flexibility and autonomy.
How does exchange-rate targeting limit monetary policy?
When a central bank commits to defend a currency level, it must set interest rates to support that level, even when domestic conditions call for a different rate. This removes the independence that inflation or interest-rate targeting regimes retain.
