Interest rates are determined by the market participants at the expectation of infla-tion of the currency and the risk they bear. Based on it the profitability and risk of a calculated venture the allocation of capital is planned. For example CAPM is based on a risk free investment, which normally should represent the actual inflation, but currently there are negative interest rates. The difference between the risk free in-vestment and the risk adjusted preferred investment is the overperformance. When the assumption especially in terms of inflation are wrong or manipulated it forts to a misallocations of capital. Also real economic growth has to be bigger than the real inflation, otherwise the capital stock depreciates. To keep the value of the capital stock it has to grow with the devaluation of the currency. Stable and sustainable growth needs a stable capital stock and reliable information during the planning hori-zon.
