Country’s Price Inflation

这是关于汇率的问题，影响因素以及作用

There are three factors will determine the exchange rate. A country’s price inflation, a country’s interest rate and market psychology. In the PPP model, we assume that the spot rate of two countries equal to the inflation rate of two countries.

When a country raising its interest rate, the inflow of the foreign capital will be increasing the demand for its currency and the exchange rate will rising at the same time. On the contrary, lower interest rates may leads to capital outflows and the exchange rate decrease.

Inflation refers to the phenomenon of currency devaluation and price rise caused by the money supply exceeding the amount of money needed for commodity circulation. When a country experiencing inflation, its commodity cost will inevitably increase, the price of export commodities expressed in foreign currency will inevitably rise, the competitiveness of the commodity in the international market will be weakened, and the excessively high inflation rate will inevitably leads to a capital outflow, which will also affects the market's expectation of future prices and exchange rates.

People's optimism about a country's economic situation, balance of payments, inflation and interest rate will causes a large number of purchases of its currency, causing the exchange rate to rise. Conversely, bearish, the exchange rate will fall. This kind of psychological expectation is accompanied by various speculative factors, and even some rumors and the speech of a certain leader will cause speculative activities and may set off an uproar in the foreign exchange market, resulting in the fluctuation of the exchange rate.

Because those products are irreplaceable, which means, no country, company or person can find a similar product to replace it. Technological innovation and technological progress can well enable these countries with strong currencies to make full use of their abundant resources to reduce the risks brought by foreign exchange rate.
