The Crawling Peg Exchange Rate Mechanism: A Strategic Tool for Economic Stability?

In recent times, the International Monetary Fund (IMF) has recommended that Bangladesh adopt a Crawling Peg Exchange Rate system as a response to its balance of payments (BOP) decline from peak of $48 billion to ~$20 billion and a concerning 35% currency depreciation over the last 19 months.

Understanding the Crawling Peg Exchange Rate:

The Crawling Peg, an innovative hybrid of fixed and floating exchange rate systems, allows a nation's domestic currency to fluctuate within predetermined upper and lower bands. It is a strategic response to economic dislocation, inflation management, and uncontrolled currency devaluation. Central banks may employ a known formula or frequent adjustments to deter speculators.

Different Types of Crawling Pegs:

There are two primary forms of Crawling Pegs, each with distinct characteristics:

Active Crawling Peg: Central banks publicly announce upper and lower bands and actively maintain the peg through incremental buying and selling in the Forex market. This strategy aims to manipulate inflation expectations and stabilize the exchange rate.

Passive Crawling Peg: Adjustments under this model are tied to coincidental factors, such as changes in inflation rates. They are typically announced monthly or bi-monthly, with the primary goal being the preservation of foreign currency reserves.

Advantages of a Crawling Peg Exchange Rate:

Stability with Trading Partners: It promotes stable exchange rates, which are essential for international trade.

Minimized Forex Fluctuations: A Crawling Peg reduces excessive Forex rate fluctuations, enabling better planning for businesses and investors.

Inflation Expectations Management: It provides a tool for managing inflation expectations, contributing to price stability and economic growth.

Preservation of Foreign Exchange Reserves: By moderating the need for central bank interventions, it helps protect foreign exchange reserves.

Controlled Devaluation: Allows for a controlled devaluation, preventing uncontrolled currency devaluation during periods of high inflation and economic instability.

Disadvantages of a Crawling Peg Exchange Rate:

Artificial Exchange Rates: May lead to exchange rates that do not fully reflect market forces, potentially distorting resource allocation and market efficiency.

Speculation Risk: Vulnerable to speculative attacks, especially if market participants doubt its sustainability, which could strain foreign exchange reserves.

Active Intervention: Active Crawling Pegs may lead to increased central bank interventions and manipulations, potentially draining foreign exchange reserves.

Economic Impact: The system may not address underlying structural issues in the economy and should not be seen as a long-term solution.

Countries Using the Crawling Peg System:

Currently, only Nicaragua and Vietnam employ the Crawling Peg system. China has adopted a variation, often termed a delayed peg. In the past, countries like Botswana, Argentina, Ecuador, Uruguay, and Costa Rica experimented with Crawling Pegs but later abandoned them. While Crawling Pegs are relatively rare, other countries use various exchange rate mechanisms, including conventional pegs, managed floats, and independent floats, reflecting the complexities of the global economy.

Real-Life Example: The Hong Kong Dollar's Management System:

A striking real-life example of exchange rate management is the Hong Kong Dollar (HKD), which uses a crawling peg system. The Hong Kong Monetary Authority (HKMA) sets a central value for the HKD against the US dollar and announces a target exchange rate band, typically +/- 1.85% around the central value. The HKMA intervenes in the foreign exchange market to maintain the exchange rate within this band, buying HKD when the rate falls below the lower band and selling HKD when it exceeds the upper band. Periodic adjustments, based on factors like inflation differentials, are also made to keep the system responsive.

In practice, the HKMA's interventions are relatively infrequent due to its substantial foreign reserves, further supported by interest rate policy and capital controls. This exemplifies the successful management of a crawling peg system in the real world, demonstrating its capacity to provide stability in currency markets and economic planning.

Risks and Limitations:

However, the Crawling Peg system is not without its risks. If policymakers are not careful, the system can be vulnerable to speculative attacks. Additionally, the Crawling Peg system can limit the central bank's flexibility to respond to economic shocks.

In the case of Bangladesh, the adoption of a Crawling Peg warrants careful consideration. While it can provide short-term relief, it should not substitute the necessity for addressing deeper structural issues within the economy. A well-balanced approach that combines the advantages of a Crawling Peg with broader economic reforms is essential for long-term stability and growth.
