Problem 9.1 Ecuadorian Hyper-Inflation

moved from S5,000/$ to S25,000/$. What was the percentage change in its value?

The Canadian dollar’s value against the U.S. dollar has seen some significant changes over recent history. Using the following
graph of the C$/US$ exchange rate for the 30 year period between 1980 and end-of-year 2010 to estimate the percentage change in
the Canadian dollar’s value (its affectionately known as the "loonie") versus the dollar for the following periods.
Problem 9.2 Canadian Loonie
The 'spike' in the Loonie in 2008-2009, was dramatic, but was considered by many a nervous reaction to the financial crisis which
was largely experienced in the United States at the time, and not in Canada.

Problem 9.3 Nigerian naira Floated
On Friday June 17, 2016, the Central Bank of Nigeria (CBN) abandoned the Nigerian naira’s (NGN or ₦) fixed exchange
rate and allowed the currency to float. Previously fixed against the U.S. dollar at NGN 196.50 = 1.00 USD, the naira
closed at NGN 279.50/USD on Monday June 20, the first day of trading following the float. The naira quickly quickly
floated (sunk) to NGN 324.50/USD by August 18. Similarly, the naira fell from NGN 221.2001 = 1.00 EUR
toNGN316.7294 /EUR on June 20, and NGN 347.7721/EUR on August 18.

Problem 9.4 Turkish Lira Devaluation
The Turkish lira (TL) was officially devalued by the Turkish government in February 2001
during a severe political and economic crisis. The Turkish government announced on February
21st that the lira would be devalued by 20%. The spot exchange rate on February 20th was

Problem 9.5 Argentine Peso's Anguish
As illustrated in the graph, the Argentine peso moved from its fixed exchange rate of Ps1.00/$ to over Ps2.00/$ in a matter of days in early January 2002. After a brief period of high volatility,
the peso's value appeared to settle down into a range varying between 2.0 and 2.5 pesos per dollar. If you were forecasting the Argentine peso further into the future, to March 30, 2002, how
would you use the information in the graphic -- the value of the peso freely-floating in the weeks following devaluation -- to forecast its future value?
The period immediately following the peso's devaluation was highly volatile and a period of transition. Most forecasters would view the February period as a period in which the new
exchange rate is beginning to "stabilize" in its trading.

Problem 9.8 Mikhail Khorodovsky's Dilemma
Mikhail Khodorkovsky was one of the infamous Russian oligarchs, accumulating billions of dollars in wealth in the mid-1990s with the fall of the Soviet
Union. But in 2003 he had been imprisoned by the Russian state for a decade for tax evasion. Upon his release from prison in 2013 he had taken up
residence in Switzerland – with most of his money.
In November 2014 Mikhail held a portfolio of USD 200 million and CHF 150 million in Swiss banks, in addition to accounts in Russia still holding RUB
1.2 billion. Using the exchange rate table, answer the following:
Exchange Rates Nov 7, 2013 Nov 7, 2014 Dec 4, 2014 Dec 16, 2014 Dec 24, 2014 Jan 16, 2015

Problem 9.9 Trepak -- The Russian Dance
Calculate the percentage change in the value of the Ruble for the three different crossrates shown for the six datesbelow. Did the ruble fall further against
the U.S. dollar or the Swiss franc?
The Russian ruble clearly fell further against the Swiss franc than it did the U.S.
dollar. It is more evident by simply looking at the percentage change from Nov
2014 through Jan 2015.
a. BP's dividend received in USD in July 2014 Values
Rosneft dividend to BP (July 2014) in Russian rubles RUB 24,000,000,000.00
Spot rate, July 2014, RUB = 1 USD 34.78
USD 690,051,753.88
b. BP's dividend received in USD in July 2015? Values
Rosneft dividend to BP in Russian rubles RUB 24,000,000,000.00
Spot rate, July 2015, RUB = 1 USD 75.00
USD 320,000,000.00
c. If Rosneft suffers from Russian recession?
c. If the combination of Western sanctions against Russia and lower global oil prices truly sent the
Russian economy into recession, and the spot rate was RUB 75 = 1.00 USD in July 2015, what might
BP's dividend be in July 2015?
BP's dividend could very well be zero in 2015 if the Russian economy worsened in the first half of the
year, and Rosneft's profitability was destroyed from economic conditions, sanctions, and the fall of the
ruble.
Even if Rosneft did manage to achieve a positive level of profit in 2015, given its sizeable debt payment
obligation, it could choose to not pay a dividend in order to preserve cash flow for debt service.
Finally, at least in the early spring of 2015, there was a real possibility that the Russian government could
institute capital controls that would prevent the payment of the dividend to a foreign stockholder like BP.
Capital controls were a real possibility because of the plummeting value of the ruble.
Problem 9.10 BP and Rosneft 2015
BP (UK) and Rosneft (Russia) had severed a long-term joint venture in 2013, with Rosneft buying BP
out with $55 billion in cash and a 20% interest (equity interest) in Rosneft itself. Rosneft financed a large
part of the buyout by borrowing heavily. The following year, in July 2014, BP received a dividend on its
ownership interest in Rosneft of RUB 24 billion.
But Rosneft's performance had been declining, as was the Russian ruble. The winter of 2014-2015 in
Europe was a relatively mild one, and Europe's purchases of Rosneft's natural gas had fallen as had the
price of natural gas. Rosneft's total sales were down, and the ruble had clearly fallen dramatically. And to
add debt to injury, Rosneft was due to make a payment of USD 19.5 billion in 2015 on its debt from the
BP buyout.
a. Assuming a spot rate of RUB 34.78 = 1.00 USD in July 2014, how much was the dividend paid to BP
in U.S. dollars?
b. If Rosneft were to pay the same dividend to BP in July 2015, and the spot rate at that time was RUB
75 = 1.00 USD, what would BP receive in U.S. dollars?
