Introduction

Mundell and Polak models, indeed, rank among the most prominent frameworks in international economics representing fundamental findings on the relation between internal monetary policies, fixed exchange rate systems, and international stores. In the fixed exchange rates, this analysis goes further behind to consider what happens after money finishes in already an effort for foreign exchange under a managed currency regime (Makin, 2005). In addition, this analysis includes an explanation of how these models guide IMF policy concerning borrowing by debtor nations seeking bailout packages if there are countries that go begging.

Recognizing that the monetary expansions under fixed exchange rates imply quite different challenges and arcs explored using the Mundell-Fleming and Polak models, sufficient to comprehend lies in defining their results. The following discussion is designed to explain the countries’ adjustment mechanisms given by models, international reserves implications that were a result of the above measures, and government borrowing conditions by IMF (Arslanalp, & Simpson-Bell, 2022). In terms of seeking contributions regarding a more sophisticated and detailed understanding of interconnections between domestic monetary policies, fixed exchange rates as well as foreign financial stability – this comparative analysis can bring forward analytical findings that can help identify features that are similar in real-life and conclusions about their implications for global economic policymaking.

Mundell-Fleming Model: Fixed Exchange Rates and Capital Mobility

The model of Mundell and Fleming (1962) allows interpreting of the process of interaction between fiscal and monetary policies in an open economy and maintains constant parities for a foreign currency based on moves by authorized valuables, with more accentuation given to the effect of money mobility. The model assumes that the latter increase in the domestic money supply will lead to a decline in interest rates (Guo, Ottonello, & Perez, 2023). First, the explanation behind these actions is aimed at reducing borrowing costs attracting investment and thereby spending which declines with a rising supply of money.

On the other hand, the mobility of capital implies that there is a complication in this regard as well. With low interest rates, investments in domestic assets become less attractive than those in some foreign investments, leading to an outflow of capital in search of higher returns abroad. Here, at the same time, the capital from foreign is moving into the domestic national economy which is due to low interest rates. This Mobility of Capital institutions now becomes one of the superior aspects of the PIC scenario.

Although the first-round effect of higher capital inflows is associated with an appreciation in terms of their domestic currencies, this may prove costly to the balance of payments because net exports can be eroded. An increase in exchange rate increases the price of domestic goods and services which are relatively high for foreigners, thus causing demand to fall as well as negatively impacting exports and importing other foreign products (Fofanah, 2020). This trade imbalance leads to a worsening situation concerning terms of trade. In this way, the model of Mundell-Fleming emphasizes difficulties caused by capital mobility in maintaining external balance and reserve stability under a fixed exchange rate.

Adjustment Mechanism: Capital Flows and Balance of Payments

The situation, in which the domestic money supply increases and as a consequence interest rates lower their values according to the Mundell-Fleming model is addressed immediately. This negative trend is a catalyst for capital transfers and foreign investors respond to it by privileging high domestic returns (Dixon, Schena, & Capapé, (2022). On the other hand, capital inflow stimulates a complex dynamic adjustment process that will not only affect the balance of payment.

With foreign capital flooding in, there is then a high demand for the domestic currency which gets appreciated against other currencies as shown by the evolution of the exchange rate. This appreciation, however, has two sides of the same coin; a reflection of the beauty of the domestic market, and in the end it threatens to adversely affect export activities by increasing competition in e-competition (Bhat, & Bhat, 2022). Thus, the hiking exchange rate makes domestic products and services relatively expensive for foreign customers leading to a reduction in export competitiveness.

This adaptive mode becomes clear when we consider the balance of payments. The net export falloff caused by appreciation suggests that the value corresponding to imports of a nation is greater than its exports where a deficit in trade arises. This leads to a state of unbalanced payment position.

Accordingly, the adjustment process of Mundell and Fleming’s model shows how domestic monetary policy should make an intimate dance with capital flows along with all harmony constituted by fluctuations in the balance of payments. This highlights the importance of this model considering the problems facing maintaining external balance under fixed exchange rates and trade reserves.

Impact on International Reserves

The external effect of increased domicile money supply in the Mundell-Fleming model is indirectly through international reserves in a fixed rate scenario. The Central Bank intervenes in the monetary market to sell the local currency thereby determining its price and level while fixing the exchange rate for it to be compatible with the inflation target (Rossi, 2023). This intervention prevents this imbalance brought by the decrease in net exports through the utilization of international reserves to operate it.

However, the fastest and an efficient means of adjustment to address monetary equilibrium while keeping in mind the challenges posed by a greater money supply is the depletion of international reserves. Thus, within the framework of pegged exchange rates, the model predicts that an increase in the domestic money supply is going to be associated with a decline in international reserves since at that point central banking interventions carry out strategic retreats from keeping the defined exchange rate constant (Bordo, & Levy, 2021). This highlights the fact that there is a very complicated relationship between currency adjustments within monetary policy and the management of a country’s international reserves.

With regards to the illustrations, it is sufficient to note the Mexican Peso Crisis of 1994 that proves all imperative predictions shaped by the Mundell-Fleming model under consideration. During a bid to foster economic growth, Mexico¿s money supply was increased resulting in a reduction in interest rates (Lustig, 2000). It led to a massive flow of capital into the country, which resulted in appreciation of the peso. On the contrary, the escalating currency affected Mexico unfavorably by posing some threat to their competitive nature of exports. The outcome was an unstable equilibrium of BOP leading to a crisis and forcing the country to exhaust its international reserves, from which it supported outflows due to currency instability and effects associated with domestic money’s increase.

Polak Model: Fixed Exchange Rates and Current Account Dynamics

While the Polak model is yet another preparatory framework in international economics, the foundation of his model rests on intricacies involving the current account and domestic policies alongside monetary flows as part of balance payments under fixed exchange rates. However, since the Mundell-Fleming model takes into consideration the aspects of capital movements which includes the mobility effect, Polak’s model is centered on domestic policy determination of the current account.

Despite this model not explaining in detail the workings of the current account, it addresses how these changes in fiscal policy and central bank policy impact country-level balances under fixed exchange rates. Through examination of such features of these dynamics, the Polak model brings an insight into the subtlety and relations between policy decisions, actual trade shipping as well as external equilibriums in the fixed subscription regime.

The value of the Polak model lies in its potential to shed clear light on the intricacy and adaptation that may be faced by countries due to constant efforts being expended towards the achievement of stability in budgeting accounts outside (Korgbeelo, 2023). In the analytical framework we have introduced, our understanding of what can take place in a country’s Macroeconomy when fiscal and monetary measures ripple through its economic landscape hence affecting trade balance due to fixed exchange rates becomes enhanced.

The version by Polak centres on the operation of the adjustment mechanism which is contingent upon such factors as the current account. An increase in the money supply started as a domestic monetary increase spurs an expansion of the domestic output. This economic expansion, however, puts up import demand as domestic demand for goods and services soars. As a result of this, the current account balance worsens because of increasing imports which work as one such channel through which changes in the money supply affect external trade dynamics for a nation-state operating under a fixed exchange rates regime.

 Impact on International Reserves

In the Polak model, one of the central ideas is that if we have a fixed exchange rate system in place, then it falls to the role of some kind of authority – let’s say call it a central bank – to preserve value for the established currency. The actions of a central bank affect the environment that this newly introduced money will go on to influence (Borio, & Zabai, 2018). As imports increase and thus, worsen the current account balance in response to an expansionary move as manifested by increased supply from what is now additional money in circulation, the central bank attempts to reverse such trends through an intervention aimed at balancing these shifts away from equilibrium. The use of its international reserves by the central bank is designed to support the fixed exchange rate measure, as in response to the higher imports that determine the market disproportionately shifting, it sells foreign currencies. This intervention helps make the international reserves on fixed growth paths, as well as emphasizes the endogeneity between current account dynamics and reserve accumulation in a set exchange rate arrangement.

Example: Thailand during the Asian Financial Crisis (1997)

The Polak mode dynamics are demonstrated in the iron of Thailand during the groundbreaking Asian Financial Crisis and its effects on Delhi in 1997. Skrtic’s 2003 paper presents his model for describing generating economic interdependencies between different countries with specific mention of India and Thailand to serve as a case study (Ainscow, & West, 2015). Each element within this model has The move to have the Thai government well adopt to engage in liberal monetary policies has led as a result to an appreciation of capital inflow and also the great investment funds flow into Thailand. Thus, the widening current account deficit coming from what caused it to expand was increased imports. To maintain the fixed rate of 1 USD =1 AED which was the par value, the central bank had to sell foreign currencies from its international reserves. On the other side, the hike in foreign currencies’ requirement during this crisis caused an alarming repletion of Thailand’s international reserves which is proof of a real-life situation that lies between monetary policies, current account balance as well and international reserve management under a fixed exchange rate system.

IMF’s Approach to Government Borrowing and Fixed Exchange Rates

The International Monetary Fund (IMF), determines its stance under borrowing policies of the government in such debtor nations that seek aid towards financial stabilization on an understanding of how monetary policies domestically prove to shape the balance-of-payments as well as international reserves. As monetary decisions frequently carry with them certain risks, the IMF has sought to enforce conditions including adding disciplines in fiscal and structural reforms (Mussa, & Savastano, 1999). The effort can reduce negative effects on the foreign sectors, which allows for creditor and debtor countries to resume a stable economic position that doesna€™t reveal crises associated with fixed exchange rates.

Conditionality and Fiscal Policy

The Greek debt crisis in the year 2010 is considered one of the great instances that highlights how GMI deals with borrowing by the government under fixed exchange rates. Graced with the extreme financial crisis, Greece applied for aid and the provisions that the IMF imposed on its loan acquisition were presented in strict terms (Wyplosz, & Sgherri, 2016). These were structural requirements for fiscal austerity and reforms that were all-encompassing. This felt that the first objective was to correct disquiet in Greece‘s balance of payments position such that it could comply with its external commitments However this left international reserve positions the poorer. This case analysis helps to demonstrate the activity of the IMF towards advising measures that seek to target deeper economic susceptibilities as well as stabilize nations that are faced with fiscal and external challenges.

Example: Greece’s Debt Crisis (2010)

However, the position of the IMF regarding government borrowing under fixed exchange rates can be evidenced by a stand on the Greek debt crisis in 2010. Greece was in the middle of an intense economic crisis so necessary strategies had to be put in place which would allow it to borrow from the IMF, which came with stringent conditions (Kalaitzake, 2017). The terms imposed fiscal tightening and reform of the structural balance to achieve an equilibrium of payments for Greece. The IMF’s objective was twofold: In the event, such steps as to re-establish fiscal integrity and revitalize economic growth radiating out without any further reduction in reserve currency values. Such a situation in which this case goes to show how the IMF plays an important role in managing policies for debtor states that are supposed to find ways of dealing with economic core issues besides ensuring stability in fixed exchange rates.

Flexibility in Exchange Rates: A Potential Solution

By asserting a more lenient position regarding exchange rates it can be said that the refinement of foreign deals lies in admitting the benefits such a system would add. In the case of floating exchange rates, which is an alternative to a constant system, a flexible arrangement provides some possible answers to the setbacks proposed in the Mundell-Fleming and Polak models (Genberg, 2010). The core difference owing here to the fact that flexible rates allow for automatic adjustments.

When it comes to the case of a domestic money supply increase, B is characterized by a flexible exchange rate system that enables the currency to depreciate. This depreciation serves as a measure that builds up export competitiveness mitigating the offset of negative impact in the balance of payments (Diaz Sanchez, & Varoudakis, 2013). The currency dynamic effects of a flexible exchange rate system automatically decrease the amount of pressure on international reserves, leading to a framework that is more stable for transferring monetary growths without great imbalances in gross. Such flexibility is a must factor in ensuring a stable and resilient economy amidst constantly changing global economic circumstances.

Monetary Expansion without Balance of Payments Crisis

Under a regime of flexible exchange rates, the rate is allowed to accommodate market changes in minute time steps. Under a situation where there is an upward adjustment of the amount of money circulating in the domestic economy, the affected currency tends to depreciate because, by association, it will result from a greater supply than demand (Johnson, 2013). Such depreciation then becomes a significant adjustment catalyst. Mainly, the lower rate of exchange represents foreign consumers’ prices for the country`s exports.

The depreciation boosts export activity in the sense that it reduces the price of goods and services within the home country, making them available for a wider range of customers in external markets. This, in turn, reduces the usual negative impact of a rapid increase in domestic money supply on the current account. Thus negatives intended consequent to the expansion of internal circulation are thereby tamed under a floating contraction rate system. Such adaptability provides more organic, market-oriented adjustment to monetary growths, which in turn reduces the possibility of the balance of payments crisis. The arguing is to this effect; flexible exchange rate systems offer a way of facilitating monetary policy adjustments without the rigidities observed in fixed exchange rates.

Example: Canada’s Flexible Exchange Rate Regime

A very good case of a system that can be designed to efficiently handle monetary shocks is created by the example of Canada’s ‘flexible exchange arsenal regime’. In reaction to the monetary expansion by the Bank of Canada, the Canadian dollar will depreciate relative to other currencies (Kia, 2013). This depreciation works as an automatic adjustment mechanism for the export side industry, which eventually leads to improved export competitiveness.

As the Canadian dollar depreciates against foreign currencies, Canadian goods become cheaper which leads to stronger demand for exports. The response further enables Canada to be in a position to negotiate changes in money supply much better without resulting in a balance of payments crisis. It was the adaptability that has proved essential for absorbing economic shocks and securing not only price but also stability in our country’s external accounts, thus proving the benefits of a flexible exchange rate system with a view to monetary policy and stably maintaining levels of international competitiveness.

Conclusion

In turn, each model the Mundell-Fleming and Polak models highlights the potential outcomes of increased domestic supply of money under fixed exchange rates. In light of these models, the IMF’s policy on government borrowing is related to this comprehension and stresses that fiscal prudence was important in order not to have a balance as the crisis problem. The possible introduction of a more flexible exchange rate rule is backed by utilizing the capacity to absorb the monetary expansion without generating large external imbalances. Real life in countries like Mexico and Thailand exemplifies these models in practice. In conclusion, thorough perspectives on such models are an utmost need for the state’s policymaking and international financial burden management.
