Capital flow management measures

Capital flow management measures (CFMs) are policy measures designed to limit international capital flows, including cross-border investments, borrowing and other financial transactions. Governments and central banks may use these measures to address risks arising from large or volatile capital movements and to support macroeconomic and financial stability. The International Monetary Fund (IMF) recognises CFMs as part of the policy toolkit available to countries managing the benefits and risks associated with international capital flows.

CFMs may apply to capital inflows, capital outflows or particular categories of cross-border financial transactions. Their design varies according to national circumstances, the nature of financial vulnerabilities and the objectives of the authorities implementing them. Some measures are based on the residency of the parties involved, while others restrict capital movements without explicitly distinguishing between residents and non-residents.

Background

International capital flows enable countries to attract foreign investment, diversify funding sources, finance economic development and integrate into global financial markets. However, large and volatile flows can also contribute to exchange-rate pressures, asset-price fluctuations, excessive borrowing and financial instability.

Capital inflows may accelerate credit growth and create vulnerabilities when banks, companies or households accumulate substantial foreign-currency liabilities. Sudden reversals can cause capital outflows, put pressure on foreign-exchange reserves and increase the cost of servicing foreign debt.

The IMF adopted its Institutional View on the Liberalization and Management of Capital Flows in November 2012 to provide a framework for assessing capital-account policies and advising member countries. A review in 2022 expanded the framework, including guidance on the pre-emptive use of certain measures to address existing financial vulnerabilities.

Types

Residency-based measures

Residency-based CFMs regulate cross-border financial transactions by distinguishing between residents and non-residents. These measures are commonly described as capital controls.

Examples include:

Limits on foreign investment in domestic securities.
Restrictions on non-resident investment in specified sectors.
Restrictions on particular cross-border borrowing or lending transactions.
Taxes or additional charges on certain transactions involving non-residents.

The scope and intensity of residency-based measures depend on the applicable national laws and regulatory framework.

Other capital flow management measures

Other CFMs do not explicitly discriminate according to the residency of the parties involved but are nevertheless designed to limit capital flows in the circumstances in which they are introduced.

Examples may include:

Minimum holding periods for particular investments.
Restrictions on certain foreign-currency transactions.
Limits on specific forms of external borrowing.
Regulatory requirements that constrain particular cross-border financial transactions.

Whether a measure qualifies as a CFM depends on its design and the country-specific circumstances surrounding its introduction or adjustment. A policy that affects capital flows is not automatically classified as a CFM.

Measures affecting inflows

Measures affecting capital inflows are designed to influence the volume or composition of foreign capital entering a country. Authorities may consider them when rapid inflows contribute to excessive credit growth, asset-price pressures, foreign-currency exposures or other financial vulnerabilities.

Examples include limits on non-resident purchases of domestic securities, restrictions on foreign borrowing and certain taxes on cross-border investments.

Measures affecting outflows

Measures affecting capital outflows restrict or influence the movement of domestic or foreign capital out of a country. They may be considered in circumstances involving disruptive outflows, severe foreign-exchange pressures or threats to financial stability.

Examples include limits on certain transfers abroad, restrictions on specified foreign-exchange transactions and requirements governing the repatriation or transfer of funds.

The appropriateness and effectiveness of these measures depend on the circumstances in which they are applied and their interaction with other economic policies.

Capital flow management and macroprudential policy

Capital flow management measures are distinct from, but can overlap with, macroprudential measures.

Capital flow management measures are designed to limit capital flows. Macroprudential measures (MPMs) primarily seek to reduce systemic risks in the financial system, including risks associated with excessive leverage, credit growth and interconnected financial institutions.

A measure may fall into both categories when it is designed to limit capital flows in order to reduce systemic financial risks. The IMF refers to such measures as capital flow management measures and macroprudential measures (CFM/MPMs).

Examples of macroprudential measures that are not necessarily CFMs include loan-to-value limits on mortgages and debt-to-income limits on household borrowing. Their classification depends on their design and circumstances rather than simply their effect on international capital movements.

Objectives

The objectives of CFMs may include:

Reducing risks associated with unusually large or volatile capital flows.
Limiting the accumulation of foreign-currency mismatches.
Reducing excessive external borrowing in vulnerable sectors.
Supporting financial stability during periods of market stress.
Mitigating pressures associated with disruptive capital outflows.
Providing policymakers with additional time to implement broader economic adjustments.

CFMs are not a substitute for appropriate monetary, fiscal, exchange-rate and financial-sector policies. The IMF's framework emphasises that their usefulness must be assessed in the context of the country's overall economic circumstances.

Economic effects

Potential benefits

CFMs may provide policymakers with additional tools to address financial vulnerabilities when conventional macroeconomic measures are insufficient or take time to work. In particular circumstances, they may help limit excessive foreign-currency borrowing, reduce exposure to volatile short-term capital and lessen risks to domestic financial institutions.

They may also help authorities manage the pace of financial integration in accordance with a country's institutional capacity and level of financial development.

Costs and limitations

CFMs can also impose economic costs. Depending on their design and implementation, they may:

Reduce access to international financing.
Increase the cost of capital for domestic firms.
Distort investment decisions and the allocation of financial resources.
Encourage transactions through less-regulated channels.
Create opportunities for regulatory arbitrage.
Reduce investor confidence if introduced unpredictably or maintained for prolonged periods.

Their effectiveness may be limited when investors can redirect transactions through alternative financial instruments, jurisdictions or intermediaries. Poorly designed restrictions can also interfere with legitimate trade and investment activity.

IMF Institutional View

The IMF's Institutional View provides guidance on the circumstances in which capital flow liberalisation and management measures may be appropriate. It recognises that international capital flows can generate substantial economic benefits but may also create macroeconomic and financial stability risks.

Under this framework, CFMs may be useful in certain circumstances, including episodes of excessive inflows, disruptive outflows or the presence of existing financial vulnerabilities that cannot be adequately addressed through conventional policies alone. The framework also recognises that some CFMs may be used pre-emptively to address systemic risks arising from foreign-currency mismatches.

The IMF emphasises that CFMs should not substitute for warranted macroeconomic adjustment. The assessment of a measure considers its design, the risks being addressed, the available policy alternatives and the circumstances in which it is introduced. Pre-emptive CFM/MPMs should be targeted, calibrated to the identified risks, transparent and temporary to the extent possible.
