This chapter deals with exchange rate systems. We first consider the concept of exchange rate, and then discuss the operations and adjustment mechanisms under the floating exchange rate system and the fixed exchange rate system. We also provide a brief history of the international monetary and exchange rate systems, which can help us to examine the advantages and disadvantages of the two exchange rate systems.

Interest Rate Parity–Money is worth what it can
earn.
–Interest rate parity means equal interest rates.

The Exchange Rate
Interest Rate Parity If the interest rate on the dollar is
higher in the United States than another, the demand for U.S. dollars rise and the exchange rate rises until expected interest rates are equal.

Example:
US$1 = ¥100

Price of a big Mac in Japan = ¥ 200
Price of a big Mac in Japan = US$2

Example:
If the inflation rate in Japan is 5% higher than that in the USA, the Japanese yen will depreciates against US$ by 5%.
The PPP theory also states that the exchange rate between any countries’ currencies adjust to reflect differences in the price levels (or inflation rate) in the two countries.

The Exchange RatePurchasing Power Parity
– If prices increase in Canada and other countries but remain constant in the United States, people will generally expect that the value of the U.S. dollar is too low and will expect it to rise.
– Supply of (fall) and demand for (rise) dollars change
– The exchange rate changes (rise), US$ appreciate

The fixed exchange rate system is the system whereby the exchange rate is set by a government or by agreement among countries (Lam 1996: 297).
In a country adopting a fixed exchange rate system, the monetary authority of the country buys and sells foreign currencies to maintain the value of its domestic currency in the foreign exchange market.

Under a floating exchange rate system, the market mechanism would operate to restore equilibrium simultaneously in the BOP and the exchange rate.
Whenever a country experiences a BOP deficit, the country’s currency will depreciate to restore equilibrium in the BOP.
Whenever a country experiences a BOP surplus, the country’s currency will appreciate to restore equilibrium in the BOP.

The Marshall-Lerner condition says that depreciation (or in fixed ERS, devaluation) will improve the balance of payments position of a countryprovided that the sum of elasticities of foreign demand for domestic exports and domestic demand for imports is greater than unity (1).

When there is a BOP deficit (e.g. X < M),
the foreign reserves of that country will fall.
This also implies a fall in the country’s money supply.
Price (fall) and real interest rate (rise) adjustment can restore the BoP to equilibrium/balanced market BoP.

Effects on the neighborhood countries of the devaluation
• Goods of these countries is much cheaper relative to Hong Kong’s
• Effect on tourist and import-export
• Effect on investment and hence economic growth

Floating Exchange Rate Fixed Exchange Rate
A floating exchange rate system frees the govern-ment from taking care of the BOPs condition and allows it to use its resources exclusively tomaintain internal balance.
Maintaining internal& external balances
The government must hold adequate reserves to maintain the fixed rate & must take measures to correct external imba-lances if the automatic adjustment mechanism works too slowly.Sometimes, there may be conflicts in maintaininginternal and external balances
![Page 55: Exchange Rate Systems This chapter deals with exchange rate systems. We first consider the concept of exchange rate, and then discuss the operations and](https://reader030.vdocuments.site/reader030/viewer/2022032518/56649cc35503460f9498be8c/html5/thumbnails/55.jpg)

The case for and against floating exchange rates
For • Monetary policy
autonomy
• Exchange rates as automatic stabilizers
Against• Discipline problem• Destabilizing
speculation and money market disturbances
• Injury to international trade and investment
![Page 56: Exchange Rate Systems This chapter deals with exchange rate systems. We first consider the concept of exchange rate, and then discuss the operations and](https://reader030.vdocuments.site/reader030/viewer/2022032518/56649cc35503460f9498be8c/html5/thumbnails/56.jpg)
69
For floating : monetary policy autonomy• Under fixed exchange rate system,
countries other than the reserve center cannot have monetary policy:– Have to adjust money supply (and hence the
interest rate) to maintain the exchange rate at a fixed level if they have no restriction on capital flow. Hence no control on inflation.
– Have to impose restriction on international payments if we want some autonomy in monetary policy distorting international trade
![Page 57: Exchange Rate Systems This chapter deals with exchange rate systems. We first consider the concept of exchange rate, and then discuss the operations and](https://reader030.vdocuments.site/reader030/viewer/2022032518/56649cc35503460f9498be8c/html5/thumbnails/57.jpg)
70
Against fixed : Tradeoff between fixed exchange rate regime and monetary policy autonomy
• Under fixed exchange rate regime, a country cannot use monetary policy to affect output
• Monetary policy, if any, serves to fix the exchange rate
• In other words, for fixed exchange rate regime, we sacrifice monetary policy as a tool to affect the economy
• Currency board system is one form of fixed exchange rate regime.
![Page 58: Exchange Rate Systems This chapter deals with exchange rate systems. We first consider the concept of exchange rate, and then discuss the operations and](https://reader030.vdocuments.site/reader030/viewer/2022032518/56649cc35503460f9498be8c/html5/thumbnails/58.jpg)
71
For floating: Exchange rates as automatic stabilizers
• A temporary fall in export demand => fall in domestic currency demand => domestic currency depreciates => cheaper export => more Qd for export
![Page 59: Exchange Rate Systems This chapter deals with exchange rate systems. We first consider the concept of exchange rate, and then discuss the operations and](https://reader030.vdocuments.site/reader030/viewer/2022032518/56649cc35503460f9498be8c/html5/thumbnails/59.jpg)
72
Against floating : Discipline
• Government might embark on over-expansionary fiscal or monetary policy, falling into the inflation bias trap because no need to worry about losses of foreign reserves.
![Page 60: Exchange Rate Systems This chapter deals with exchange rate systems. We first consider the concept of exchange rate, and then discuss the operations and](https://reader030.vdocuments.site/reader030/viewer/2022032518/56649cc35503460f9498be8c/html5/thumbnails/60.jpg)
73
Against floating : Destabilizing speculation and money market disturbances
• Anything that fluctuates, including floating exchange rate, can be speculated.
• Speculation may lead to – instability in foreign exchange markets and hence – negative effect on countries’ internal and external
balances.
• Disturbances (temporary) to the home money market could be more disruptive under floating than under a fixed rate.
![Page 61: Exchange Rate Systems This chapter deals with exchange rate systems. We first consider the concept of exchange rate, and then discuss the operations and](https://reader030.vdocuments.site/reader030/viewer/2022032518/56649cc35503460f9498be8c/html5/thumbnails/61.jpg)
74
Against floating : Injury to international trade and investment
• Fluctuating exchange rates implies more uncertain returns on investment and prices of goods traded internationally.
• Theoretically, exchange rate risk may be avoided through a transactions in the forward exchange market. – May be costly to use.

78
External Balance occurs when a country’s BOP position is in balance.
Internal balance occurs when a country can attain low unemployment and low inflation.
![Page 64: Exchange Rate Systems This chapter deals with exchange rate systems. We first consider the concept of exchange rate, and then discuss the operations and](https://reader030.vdocuments.site/reader030/viewer/2022032518/56649cc35503460f9498be8c/html5/thumbnails/64.jpg)
79
It can happen that a country pursues fiscal and monetary policies to achieve internal balance, but that these may have the opposite effect with respect to external balance.
Whether there is a conflict between the objectives of internal and external balance depends on both the initial payments position and the domestic situation.

Effectiveness of currency notes arbitrage will depend on:
(i) commitment of the Currency Board on the Convertibility Undertaking
(ii) whether banks charge a high fee for handling large amounts of currency notes
(iii)whether transaction costs in moving large amounts of currency notes is high
(iv) attitude of arbitrageurs towards the 2-day time lag (v) transferability between aggregate balance of banking
sector and currency notes(vi) whether convertibility undertaking covers aggregate
balance at the pegged rate
