Speculative Attacks on Currencies

Purpose of These Slides (1) To demonstrate how markets attack foreign

currencies. Why an attack occurs and the conditions

necessary for success. Success measured by the country

abandoning its peg (a peg is where the government is managing its currency in a very tight range to another currency, or basket of currencies).

(2) To give you examples of currency attacks and the consequences of those attacks. United Kingdom pound attack in 1992. Asian currency attack in 1997.

Market Forcing Countries to Abandon Peg: An Attack on a Currency Attacks on currencies can occur for a variety of

reasons, but essentially they all relate to: Where the market believes that the existing (i.e., pegged)

rate overstates (or understates) the currency’s “true” (intrinsic) value.

Why might a currency be perceived as overvalued? Inappropriate domestic monetary and fiscal policies. Weakness in the country’s external (trade) position. Weakness in the country’s key financial sector (banking).

Why might a currency be perceived as undervalued? Underlying strength in the economy of the country which is

not reflected in the pegged exchange rate.

Attacking a “Overvalued” Pegged Currency Attacks on an Overvalued Currency:

Currency is sold short on foreign exchange markets: Short selling: Speculators borrow

“overvalued” currency, sell it on foreign exchange markets, and intend to buy it back later when currency weakens.

Short selling puts downward pressure on the overvalued currency.

Attacking a “Undervalued” Pegged Currency Attacks on an Undervalued Currency:

Currency is bought on foreign exchange markets. Speculators buy “undervalued” currency,

and intend to sell it later when currency strengthens.

Buying the currency puts upward pressure on the undervalued currency.

Assumptions Before Attack will Proceed Before attacking a currency, speculators

must also be confident that the government of the country’s who’s currency is under attack: (1) Lacks the will to defend its currency.

Not willing to adjust interest rates (perhaps for political reasons)

(2) Lacks the resources to defend its currency. Does not have sufficient foreign exchange to support its

currency. Would need dollars or other hard currency if their currency

is being sold.

Case Study: British Pound Attack (1992) Britain joined the European Exchange Rate

Mechanism (ERM) in October 1990. ERM was designed to promote exchange rate stability

within Europe. Under the ERM, European currencies were

“pegged” to one another at agreed upon rates. The British pound was locked into the German

Mark at a central rate of about DM2.9/£ Generally feeling at the time was that this rate

overvalued the pound against the mark.

Dominance of Germany in the ERM While the ERM included many European

countries, Germany was the leading player. Therefore, the German mark was the dominant

currency in this arrangement. In addition, German monetary policy had to

be followed by the other members in order for the other member states to keep their currencies aligned with the German mark. This was especially true with regard to German

interest rates.

Series of Events Leading Up to the Attack on the Pound While the markets felt the pound was “overvalued”

when it joined the ERM, a combination of events just before and after Britain joined convinced the market that the pound was ready for speculation.

These events were: The fall of the Berlin Wall in Nov 1989 The economic “recession” in the U.K. in 1991-92.

German decided to raise interest rates in order to attract needed capital for the reunification of Germany.

The issue for the U.K. was having to raise interest rates during their recession. Political and economic component to this decision.

Response of British Government to Speculative Attack: September 1992 Pound currency attack begin in September1992

Led by hedge funds: For example, George Soros. Wednesday, September 16 (“Black Wednesday”)

Bank of England raised interest rates twice from 10% to 12% and then later in the day to 15%

Move was an attempt to make U.K. investments more attractive to overseas and domestic investors.

During the attack the Bank of England spent 4 billion pounds ($7 billion) in defense of its currency.

Buying pounds (selling U.S. dollars and German marks). Estimates: 1/3 of its hard currency was spent.

Thursday, September 17, U.K. left the exchange rate mechanism and let the pound float! Pound fell from 2.7780 to 2.413; or -13.1%

British Pound: Jan 1991 – Dec 1992

15% Change in British Pound

Case Study: Asian Currency Crisis of 1997 During the 1980s, a group of countries in

Southeast Asia – known as the “Asian Tigers” – experienced exceptionally high economic growth rates.

The economic miracle was accompanied by these countries opening up their financial markets to foreign capital inflows

Also, during this time, the currencies of these countries were pegged to the U.S. dollar.

Thailand: Background Thailand was part of the southeast Asian

region which experienced double digit real growth up to the mid-1990s. Exports were critical to the regions exceptional

growth. Thailand’s exports had increased 16% per year from

1990 to 1996. Economic growth in the region was fueled by

massive increases in foreign borrowing. Government borrowing for infrastructure investment Corporate borrowing for investment expansion.

The Thai Baht: A Pegged CurrencyThe Thai baht had been pegged to the U.S. dollar at

25 to the dollar for 13 years.

Thailand Begins to Unravel The massive increase in foreign investment

eventually resulted in: Overcapacity in Thailand Poor lending/investment decisions Investment in speculative activities (especially the property

markets) On February 5, 1997, the Thai property developer,

Somprasong Land, announced it could not make a $3.1 million interest payment on an outstanding $80 billion loan. Other Thai development companies followed and the Thai

property market began to unravel.

Currency Traders Assess the Situation Currency traders were aware of the following:

Thailand’s enormous external debt which was denominated in U.S. dollars would require a large demand for dollars.

Coupled with the debt burden, Thailand’s export growth began to slow and moved into deficit. Question: Where would the dollars come from the

finance the external debt? Traders believed the baht was “overvalued at 25

to the dollar.

The Attack on the Thai Baht Peg Believing the baht was overvalued,

speculators: Start to sell the baht short in May1997

Traders borrowed bahts from local banks and immediately resold them in the foreign exchange markets for dollars. If the baht did weaken, traders could buy

the bahts back and pay off the loan and make a profit on the dollar appreciation.

Response of the Thai Government The Thai Government initially responded by:

Purchasing bahts on foreign exchange markets Used $5 billion in this effort

Raising interest rates from 10 to 12.5% Thailand was quickly running short of U.S. dollars

They had just over $1 billion left to support the baht.

The higher interest rates raised the cost of borrowing and adversely affected floating rate loan liabilities.

Bottom line: Continuing to defend the peg was quickly approaching an impossible situation.

Releasing the Peg On July 2, 1997, the Thai government announced

they were abandoning the peg and would let the currency float. The baht immediately lost 18% of its value By January 1998, it was trading at 55 to the dollar.

Baht’s 55% Fall Against the Dollar

Contagion Effect in Asia (1997) The attack on the Thai baht, quickly spread to

other Asian currencies Example of a regional contagion effect

Concern mounted regarding the economic and financial “soundness” of these countries as well.

As a direct result, many of these Asian countries were forced to abandon their pegged regimes.

One Government, However, Was Able to Successfully Defend Its Currency Hong Kong Dollar

China purchase massive amounts of stock being sold on the Hong Kong stock exchange. Offset the short selling of hedge funds.

China sold massive amounts of U.S. dollars in defense of the HK$ Offset the selling of the Hong Kong dollar on foreign

exchange markets. The HK$ peg was successfully defended and

remains so today.
