How currency rates affect the import/export and manufacturing industry of a country


                  Since the last half century, most of the international trade is done using USD as a standard currency. Consider the trade between US and China. US exports goods and services to China and gets USD in return. It does not have to convert it back to any other currency. But when China exports goods to US, it gets USD which it has to convert into Yuan to pay its workers, other expenses domestically.

                   Consider 2 scenarios.(Fictional values to provide case)

        A) 1US$ = 10 Yuan (Implies every $ earned by Chinese will fetch them 10 Yuan)
        B) 1US$ = 7 Yuan

               Clearly case B implies stronger Yuan compared to case A. What do the people of China prefer??

Importers pay Yuan to buy US$ and then buy goods internationally. Hence they would prefer paying lesser Yuan to get a dollar and hence prefer case B.

Exporters receive US$ and convert it to Yuan and pay their expense, purchase raw materials, services within China. They prefer getting more Yuan per US$ and hence prefer a weaker Yuan which is case A.

There is a conflict of interest between both these camps and the government has to decide which camp to favor in-order to develop its domestic manufacturing at the same time not costing too much on imports. Most countries allow free fluctuation of currency rates so the currency is decided by the quantum of exports and imports. But countries like China have a tightly controlled currency.

(Note: Renminbi is the official name for the currency, and yuan is the main unit of currency)

In the 1990s, China set upon the path of liberalization but did not have any significant manufacturing base as it has today. Their aim was to provide employment to its huge population and having a huge manufacturing infrastructure was the only way ahead. China already has cheap labor as its biggest asset. All it required was good governance and "Undervalued" Yuan. 
Historical USD/RMB(Yuan) chart

Around 1980, the exchange rate was 1.5 Yuan /US$ ( 0.66$/ Yuan as from chart). Slowly, China de-valued Yuan to 8.62 Yuan/ US$( 0.116 Yuan/ US$) in 1994 and maintained around about the same rate till 2005. This clearly shows the peg being maintained for more than a decade. It was during this decade that China built a massive manufacturing base and attracted foreign investments in manufacturing sector. 

Since the Yuan was heavily undervalued, every US$ gave more Yuan to Chinese exporters who could purchase cheaper labor and avail raw materials, other services at a very cheap rate hence enabling them to make extremely cheap goods and services.

These extremely cheap goods made the products from elsewhere around the world un-competitive and slowly started wiping off the manufacturing bases at many places. Eg USA, UK, France and other developed countries as they could not match the cheap labor, cheap currency and hence the cheap goods.

Even though cheap currency sparks inflation within the country the benefits of it were enormous to China as it catapulted China as a Giant Factory and simultaneously wiped off the competition elsewhere around the world. 

We will analyze the foreign currency reserve scenario and other side-effects in the next section.

US - China debt circle, international currency wars

                            Let us try to understand the vicious circle US and China are into currently and how the whole world is at a risk of a major upheaval in the near future. This topic will involve many jargons from the finance world and I will explain them as and when they appear.

The Background - Understanding how currency rates fluctuate daily (Know it? Skip it)

                            The number of factors that determine the currency rate is large and they vary from macro-economic factors like interest rate, fiscal deficit, overall debt of the nation etc to day to day factors like demand and supply. As a thumb rule, if there is a greater demand for a particular currency as compared to other, given limited supply, that currency appreciates versus other currencies and vice-versa. This is assuming the market is free from any regulatory restriction on currency rate. Examples of free flow/market based currencies are US Dollar, Euro, Japanese Yen etc. 



                            However, there are other kinds of currencies which have government/central bank as a regulator who restrict free fluctuation of the currency. This is done for various reasons like protecting export industries for example. Such currencies are pegged (fixed) against some reference currency or a basket of currencies and the fx rate is not allowed to fluctuate or limited (capped and floored) fluctuation is allowed. To maintain this constant rate, the central bank has to play an active role to buy/sell foreign currency and maintain the peg. Example of restricted currency is Chinese Yuan.It was pegged against the US$ and slow liberalization was allowed in the last decade due to international pressure. As uneven trade between two countries follows, it creates surplus for one currency and shortage for the other. At such times, restricted currency regimes need to intervene and ensure that the fx rate is at the pegged rate by buying/selling the currencies.
