The rand (sign: R; code: ZAR) is the currency of South Africa. It takes its name from the Witwatersrand (White-waters-ridge in English), the ridge upon which Johannesburg is built and where most of South Africa's gold deposits were found. The rand has the symbol "R" and is subdivided into 100 cents, symbol "c". The ISO 4217 code is ZAR, from Dutch Zuid-Afrikaanse rand.[1]

The rand is the currency of the Common Monetary Area between South Africa, Namibia, Swaziland and Lesotho.

Coins were introduced in 1961 in denominations of ½, 1, 2½, 5, 10, 20, 50 cents. In 1965, 2-cent coins replaced the 2½-cent coins. The ½-cent coin was last struck for circulation in 1973. The 2-rand was introduced in 1989, followed by 5-rand coins in 1994. The 1- and 2-cent coins were discontinued in April 2002, primarily due to inflation having devalued them. All prices are now rounded to the nearest 5 cents.

In an effort to curb counterfeiting, a new R 5 coin was released in August 2004, as well as new banknotes in February 2005. Security features introduced on the coin include a bi-metal design (similar to the €1 and €2 coins, the Thai 10 Baht coin, the British £2 coin and the Canadian $2 coin), a specially-serrated security groove along the rim and micro-lettering. The new notes also feature a number of new security features.

The 1978 series began with denominations of 2, 5 and 10 rand, with 20 and 50 rand introduced in 1984. This series saw a major design change. In addition, the series has only one variant for each denomination of note. Afrikaans was the first language on the 2, 10 and 50 rand, while English was the first language on 5 and 20 rand. The notes still bore the image of Jan van Riebeeck.

In the 1990s, the notes were redesigned with images of the Big Five wildlife species. With the 2 and 5 rand coins replacing notes, notes were introduced in 1994 for 100 and 200 rand.

The 2005 series has the same principal design, but with additional security features such as colour shifting ink on the 50 rand and higher and the EURion constellation. The obverses of all denominations are printed in English, while two other languages are printed on the reverses, making all eleven official languages of South Africa available.

As it became clear in the early 1990s that the country was destined for black majority rule and one reform after the other was announced, uncertainty about the future of the country hastened the depreciation until the level of R 3 to the dollar was breached in November 1992. A host of local and international events influenced the currency after that, most notably the 1994 democratic election which saw it weaken to over R 3.60 to the dollar, the election of Tito Mboweni as the new governor of the South African Reserve Bank, and the inauguration of President Thabo Mbeki in 1999 which saw it quickly slide to over R 6 to the dollar. The controversial land reform program that was kicked off in Zimbabwe, followed by the September 11, 2001 attacks, propelled it to its weakest historical level of R 13.84 to the dollar in December 2001.

This sudden depreciation in 2001 led to a formal investigation, which in turn led to a dramatic recovery. By the end of 2002, the currency was trading at under R 9 to the dollar again, and by the end of 2004 was trading at under R 5.70 to the dollar. The currency softened somewhat in 2005, and was trading at around R 6.35 to the dollar at the end of the year. At the start of 2006 however, the currency resumed its rally, and, as of 19 January 2006, was trading at under R 6 to the dollar again. However, during the second and third quarters of 2006 (ie April through September), the Rand weakened significantly. In Sterling terms, it fell from around 9.5p to just over 7p, losing some 25% of its international trade-weighted value in just six months. Late in 2007, the Rand rallied modestly to just over 8p, only to experience a precipitous slide during the first quarter of 2008. As at the time of writing (Friday, October 24) the Rand stands at 10.9 to the dollar.

This downward slide could be attributed to a range of factors: South Africa's worsening current account deficit, which widened to a 36-year high of 7.3% of Gross Domestic Product (GDP) in 2007; inflation at a five-year high of just under 9%; escalating global risk aversion as investors' concerns over the spreading impact of the sub-prime crisis grew; and a general flight to "safe havens", away from the perceived risks of emerging markets. The Rand depreciation was exacerbated by the Eskom electricity crisis, which resulted in the utility being unable to meet the country's rapidly growing energy demands. In particular, major mines were shut down, with Eskom warning that major new industrial projects could not be powered until additional power generation capacity could be brought on stream - something unlikely to be achieved for at least another 5 years. This would have a significant impact on production and exports by South Africa's mining industry, and would thus worsen an already worrisome current account deficit. It is particularly unfortunate that this should have happened at a time of record high prices for hard and soft commodities.

The leu ([lew], plural: lei [lej]; ISO 4217 code RON; numeric code 946) is the currency of Romania. It is subdivided into 100 bani (singular: ban). On 1 July 2005, Romania underwent a currency reform, switching from the previous leu (ROL) to a new leu (RON). 1 RON is equal to 10,000 ROL.

Romania joined the European Union on 1 January 2007 and it is expected to adopt the euro in 2014.

On August 15, 1947, a revaluation took place, with a new leu replacing the old one at a rate of 20,000 old lei = 1 new leu. This revaluation, called a monetary reform or stabilisation measure (mica stabilizare, marea stabilizare), was carried out by the Communist authorities with absolutely no advance warning and without the possibility to exchange more than a fixed amount of money for the new currency. This was done in order to depose the former middle and upper classes of their last assets, after nationalization, to prepare for collectivization and to finalize the installation of communism. At the time of its introduction, 150 new lei equalled 1 U.S. dollar.

In the 1990s, after the downfall of communism, inflation ran high due to reform failures, the legalization of owning foreign currency in 1990, and the bankrupt policies of the former communist era, reaching rates as high as 300% per year in 1993. By September 2003, one euro was exchanged for more than 40,000 lei, this being its peak value. Following a number of successful monetary policies in the late 1990s and early 2000s, the situation became gradually more stable, with one digit inflation in 2005.

The Romanian leu briefly held the dubious distinction of being the world's least valued currency unit, from January (when the Turkish lira dropped six zeros) to July 2005. However, the 1,000,000 lei bill was not the highest Romanian denomination ever. This distinction belongs to the 5 million lei bill from 1947.

On 1 July 2005, the leu was revalued at the rate of 10,000 "old" lei (ROL) for one "new" leu (RON), thus psychologically bringing the purchasing power of the leu back in line with those of other major Western currencies. The term chosen for the action was "denominare", similar to the English "denomination", to signify not a conversion, but rather a total reinvention.

The first day brought difficulties adjusting to the new paper currencies and closed ATMs (that needed reprogramming) and forcing a new calculation habit that slowed down shops and annoyed some salespeople and shoppers. The old ROL currency banknotes remained in circulation until December 31, 2006 (coins remained in circulation only until December 31, 2005), but all accounts have been converted starting July 1, 2005. There is no conversion time limit between the currencies. Retailers had to display prices in both old and new currency from March 1, 2005 until June 30, 2006. The appreciation of the leu during 2005 was about 20% against a basket of major currencies.

As of 2006, the revaluation is a potential source of confusion, especially to visitors, since both old and new currency values are commonly quoted. When written, the very large amounts in old currency are usually obvious, but in speaking inhabitants might refer to an amount of 5 new lei as simply "fifty" in reference to its value 50,000 old lei.

In 1952, coins were introduced in denominations of 1, 3, 5, 10 and 25 bani, with the 1, 3 and 5 struck in aluminium bronze and the others in cupro-nickel. In 1955, cupro-nickel 50 bani were added.

In 1960, a new coinage was introduced, consisting of 15 and 25 bani, with 5 bani, 1 and 3 lei coins added in 1963. All were struck in nickel-clad steel. In 1975, aluminium replaced steel in the 5 and 15 bani, with the same change happening for the 25 bani in 1982. Aluminium 5 lei were introduced in 1978.

Following the end of the communist regime, a new coinage was introduced between 1990 and 1992, consisting of 1 leu in bronze clad steel, 5 and 10 lei in nickel plated steel, 20 and 50 lei in brass clad steel and nickel plated steel 100 lei.

As inflation took its toll, 500, 1000 and 5000 lei coins were introduced in 1999, 2000 and 2001, respectively, and were the only coins circulating when the revaluation occurred. They were all criticized for being clumsy and difficult to use. The 500 lei coins were very thick (about 0.3 cm). Despite their small value, it took only a handful of such coins to fill one's pocket. They were also made of poor material and could be occasionally found with bite marks. The 1000 lei coin was considered too small and was also cheaply made, and the 5000 lei coin was not circular (it was a dodecagon). This made it awkward to handle and difficult to use in slot machines, where it was frequently the only coin accepted. The 500, 1000 and 5000 lei coins became worth 5, 10 and 50 bani with the revaluation.

In 1952, the Ministry of Finance introduced notes for 1, 3 and 5 lei, and the Banca Republicii Populare Romane introduced 10, 25 and 100 lei notes. In 1966, the Banca Nationala a Republicii Socialiste Romania took over the production of all paper money, issuing notes for 1, 3, 5, 10, 25, 50 and 100 lei.

In 1991, 500 and 1000 lei notes were introduced, followed by 200 and 5000 lei notes in 1992, 10,000 lei in 1994, 50,000 lei in 1996, 100,000 lei in 1998, 500,000 lei in 2000 and 1 million lei in 2003. There was also a 2000 lei note, introduced in 1999; it celebrated the total solar eclipse that occurred on August 11th, 1999. The final issues of the 2000, 10,000, 50,000, 100,000, 500,000 and 1 million lei were polymer notes.

Notes in circulation at the revaluation were:

* 10,000 lei (became 1 leu)
* 50,000 lei (became 5 lei)
* 100,000 lei (became 10 lei)
* 500,000 lei (became 50 lei)
* 1,000,000 lei (became 100 lei)

In 2005, polymer notes were introduced for 1, 5, 10, 50, 100 and 500 lei. 200 lei notes were added in 2006. The designs of the 1, 5, 10, 50 and 100 lei notes are based on those of the earlier 10,000, 50,000, 100,000, 500,000 and 1 million lei notes which they replaced. The 10 lei bill was redesigned in November 2008 (most of the graphic elements are identical, some of the safety elements were withdrawn, making its safety degree similar the the lower values of 1 leu and 5 lei bills).
