Nominal Interest Rates and Purchasing Power

The Selic rate defines the cost of money in the interbank market and influences interest rates on loans and financial applications. The net return from an application is not equal to the Selic rate, as taxes must be deducted and accumulated inflation over the period must be considered to determine the real gain.

The▁purchasing power of the▁population▁depends on the▁relationship▁between nominal▁asset▁remuneration and▁price▁developments. ▁When▁inflation▁surpasses the▁gross▁return on▁investment,▁heritage▁erosion▁occurs. The▁difference▁between the▁Selic▁rate and▁past▁inflation▁does▁not▁guarantee▁protection▁against▁future high▁price▁expectations,▁requiring the▁investor to▁assess the▁risk of▁mismatch▁between▁economic▁projections and▁effective▁results.

▁Macroeconomic▁interpretation;▁does▁not determine the▁return of an▁application▁or the▁result of the▁next▁session.
