4 International Finance and Trade Connecting several economies through Trade and Finance: the BoP the BoP is always in in balance the current account is balanced by the reserve and financial account (capital inflow = export IOU) the fundamental significance of capital movements reflects an intertemporal trade: postpone/anticipate consumption/investment: real interest rate money veils the real aspects of capital movements Francesco Franco Global Business Environment 4/32

5 International Finance and Trade Connecting several economies through Trade and Finance The BoP for the Euro The Current Account for the Euro The Financial account for the Euro The problem within the euro area - the World CA Francesco Franco Global Business Environment 5/32

11 The Gold Standard and Fixed Exchange Regimes to maintain a Fixed Exchange rate regime you need to maintain a large enough supply of foreign currency so as to be able to make private supply and demand balance at the pegged rate could be any player in the market, but tipycally a Central Bank which accumulates foreign denominated assets and gold in her balance sheet assymetry if CB can print: can always keep her currency from appreciating but not from depreciating Francesco Franco Global Business Environment 11/32

12 The Gold Standard The Gold Standard was the most important method for stabilizing exchange rates. The arrangement implied that the nation Treasury would: 1 agree to buy all gold brought to it a given price (in 1948, 35 USD per ounce, 8.75 GBP per ounce) 2 o er to sell gold freely to all comers at the same price 1. and 2. imply the dollar and the pound prices of gold are prefectly fixed (mint parity). International arbitrage then imply that the dollar-pound exchange rate is 4. Francesco Franco Global Business Environment 12/32

13 The Gold Standard and the specie-flow-price mechanism International trade could in theory deplete one country of all the gold reserves and forces it o the gold standard (mercantilistim) Hume: automatic self-correcting mechanism based on Quantity Theory (P = 1 k M): in the surplus country the increase in gold increases the quantity of M that then increases the price level P in the deficit country the decrease in gold decreases the quantity of Money that then decreases the price level Once gold became no longer important in the money supply, Treasury would follow rules of the gold-standard game (a) increase tax collection relative to expenditure, (b) increase interest rate, (c) titghten money by increasing reserves ratio, (4) put downward pressure on wage and prices Francesco Franco Global Business Environment 13/32

14 The path to the Monetary Union The European States initially adhered to the par system of Bretton Woods After a first devaluation of the French Franc and a revaluation of the Deutsche Mark in , the Hague summit sets the goal for a MU Werner Report: final objective would be the irreversible convertibility of currencies, free movement of capital, and the permanent locking of exchange rates or possibly a single currency Collapse of Bretton Woods imply the dollar starts to float, Europe reacts with the Snake from : movements in a dollar band in 1979 the EMS is launched fluctuation kept between ±2.25 percent except for Italy (and then escudo, peseta and pound) ±6 percent and realignements required unanimity Francesco Franco Global Business Environment 14/32

15 Float, example from 1919 to 1925 float between pound and dollar and again from 1973 until today Francesco Franco Global Business Environment 15/32

16 Float In a freely floating regime the supply and demand determine a flexible exchange rate. Now fundamental factors behind demand and supply are: 1 the preferences in terms of domestic versus foreign goods 2 the gowth rate of the economies 3 the di erences in prices and costs 4 the preferences in domestic and foreign assets (probable candidate to volatility) Francesco Franco Global Business Environment 16/32

21 Exchange Rates Trading You cannot go to a centralized location to watch exchange rates being determined: currencies are not traded on exchanges such as the New York Stock Exchange Instead, the foreign exchange market is organized as an over-the-counter market in which several hundred dealers (mostly banks) stand ready to buy and sell deposits denominated in foreign currencies Because these dealers are in constant telephone and computer contact, the market is very competitive; it functions no di erently from a centralized market Francesco Franco Global Business Environment 21/32
