Consumer Price Index
Swiss Consumer Price Index
The Consumer Price Index tracks changes in the cost of living. When prices are increasing too rapidly, authorities can raise interest rates to increase the cost of borrowing. This can lead to a decline in spending and force retailers to lower prices to entice buyers. For investors, an interest rate increase means higher yields on assets denominated in the currency. This drives demand for the currency but if it appears that the rate of inflation will outpace yields, investors avoid those assets.
