- 2. Chapter 6 Government Influence on Exchange Rates
- 3. Chapter Objectives • To describe the exchange rate systems used by various governments. • To explain how governments can use direct and indirect intervention to influence exchange rates. • To explain how government intervention in the foreign exchange market can affect economic conditions.
- 4. Exchange Rate Systems • Exchange rate systems can be classified according to the degree to which the rates are controlled by the government: – fixed – freely floating – managed float – pegged.
- 5. Fixed Exchange Rate System System: Rates are held constant or allowed to fluctuate within very narrow bands only. Examples: Bretton Woods era (1944–1971), Smithsonian Agreement (1971) MNCs know the future exchange rates. Governments can revalue their currencies. Each country is also vulnerable to the economic conditions in other countries.
- 6. Freely Floating Exchange Rate System (1) System: Rates are determined by market forces without governmental intervention. Each country is more insulated from the economic problems of other countries. Central bank interventions just to control exchange rates are not needed. Governments are not constrained by the need to maintain exchange rates when setting new policies.
- 7. Freely Floating Exchange Rate System (2) Less capital flow restrictions are needed, thus enhancing market efficiency. MNCs may need to devote substantial resources to managing their exposure to exchange rate fluctuations. The country that initially experienced economic problems (such as high inflation, increased unemployment) may have its problems compounded.
- 8. Managed Float Exchange Rate System System: Exchange rates are allowed to move freely on a daily basis and no official boundaries exist. However, governments may intervene to prevent the rates from moving too much in a certain direction. A government may manipulate its exchange rates such that its own country benefits at the expense of other countries.
- 9. Pegged Exchange Rate System System: The currency’s value is pegged to a foreign currency or to some unit of account, and thus moves in line with that currency or unit against other currencies. Examples: European Economic Community’s snake arrangement (1972), European Monetary System’s exchange rate mechanism (1979), Mexican peso’s peg to the U.S. dollar (1994).
- 10. Currency Boards • A currency board is a system for pegging the value of the local currency to some other specified currency. Examples: HK$7.80 = US$1 (since 1983), 8.75 El Salvador colons = US$1 (2000) A board can stabilize a currency’s value. It is effective only if investors believe that it will last.
- 11. Currency Boards Local interest rates must be aligned with the interest rates of the currency to which the local currency is tied. Note: The local rates may include a risk premium. A currency that is pegged to another currency will have to move in tandem with that currency against all other currencies.
- 12. Dollarization • Dollarization refers to the replacement of a country’s currency with U.S. dollars. • Dollarization goes beyond a currency board, as the country no longer has a local currency. • For example, Ecuador implemented dollarization in 2000.

- 14. A Single European Currency (1) • The 1991 Maastricht treaty called for a single European currency—the euro. • By June 2002, the national currencies of 12 European countries* had been withdrawn and replaced with the euro. * Austria, Belgium, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, the Netherlands, Portugal, Spain • Since then, more European countries have adopted or are planning to adopt the euro.
- 15. A Single European Currency (2) • The Frankfurt-based European Central Bank is responsible for setting European monetary policy, which is now consolidated because of the single money supply. • Each participating country can still rely on its own fiscal policy (tax and government expenditure decisions) to help solve its local economic problems.
- 16. A Single European Currency (3) • Within the euro zone, there is neither exchange rate risk nor foreign exchange transaction cost. • This means more comparable product pricing, and encourages more cross- border trade and capital flows. • It will also be easier to conduct and compare valuations of firms across the participating European countries.
- 17. A Single European Currency (4) • The interest rates offered on government securities will have to be similar across the participating European countries. • Stock and bond prices will also be more comparable and there should be more cross-border investing. • However, non-European investors may not achieve as much diversification as in the past.
- 18. Government Intervention (1) • Each country has a central bank that may intervene in the foreign exchange market to control its currency’s value. • A central bank may also attempt to control the money supply growth in its country. • In the U.S., the Federal Reserve System (Fed) is the central bank. In Europe, the ECB European Central Bank.
- 19. Government Intervention (2) • Central banks manage exchange rates – to smooth exchange rate movements, – to establish implicit exchange rate boundaries, and – to respond to temporary disturbances. • Often, intervention is overwhelmed by market forces. However, currency movements may be even more volatile in the absence of intervention.
- 20. Government Intervention (3) • Direct intervention refers to the exchange of currencies that the central bank holds as reserves for other currencies in the foreign exchange market. • Direct intervention is usually most effective when there is a coordinated effort among central banks and when the central banks have high levels of reserves that they can use.

- 22. Government Intervention (4) • When a central bank intervenes in the foreign exchange market without adjusting for the change in money supply, it is said to engage in nonsterilized intervention. • In a sterilized intervention, the central bank simultaneously engages in offsetting transactions in the Treasury securities markets to maintain the money supply.

- 24. Government Intervention (5) • Some speculators attempt to determine when the central bank is intervening directly, and the extent of the intervention, in order to capitalize on the anticipated results of the intervention effort. • Central banks can also engage in indirect intervention by influencing the factors* that determine the value of a currency. * Inflation, interest rates, income level, government controls, expectations
- 25. Government Intervention (6) • For example, the Fed may attempt to increase interest rates (and hence boost the dollar’s value) by reducing the U.S. money supply. • Some governments have also used foreign exchange controls (such as restrictions on currency exchange) as a form of indirect intervention.
- 26. Exchange Rate Target Zones • Target zones have been suggested for reducing exchange rate volatility. • An initial exchange rate will be established with specific boundaries. Ideally, the rates will be able to adjust to economic factors without causing fear in financial markets and wide swings in international trade. • The actual result may be a system no different from that which exists today.
- 27. Intervention as a Policy Tool (1) • Like tax laws and the money supply, the exchange rate is a tool that a government can use to achieve its desired economic objectives. • A weak home currency can stimulate foreign demand for products, and hence reduce unemployment at home. However, it can also lead to higher inflation.
- 28. Intervention as a Policy Tool (2) • A strong currency may cure high inflation, since it intensifies foreign competition and forces domestic producers to refrain from increasing prices. However, it may also lead to higher unemployment.
