Nousuvaihe

Nousuvaihe is a Finnish term used to describe a phase in which a measured variable begins to rise after a period of decline or stagnation. The word combines nousu (rise) and vaihe (phase) and is applied across several fields to denote an upward swing or recovery within a cyclical process.

In economics and business cycles, nousuvaihe refers to the expansion phase that follows a recession or trough. During this phase, economic activity accelerates, GDP grows, employment improves, production increases, and investment and demand start to rise again. The duration and strength of a nousuvaihe can vary, and it may be influenced by policy measures, investor confidence, and external conditions. It is typically contrasted with laskuvaihe (downturn) or taantuma (recession).

In financial markets, the term can describe a bullish or upward trend in prices after a period of decline. A nousuvaihe there implies rising stock prices, rising interest or credit conditions, and improved market sentiment, though such upswings may be gradual or volatile and are subject to market corrections.

In other domains, such as epidemiology, ecology, or demography, nousuvaihe denotes a rebound or growth phase after a low point or adverse conditions. For example, case numbers, population, or resource availability may begin to increase again, signaling renewed activity or recovery.

Overall, nousuvaihe indicates a turning point toward growth or recovery within a broader cyclical context and is often followed by subsequent phases of stabilization, peak, or renewed fluctuations. See also suhdanne, nousukausi, taantuma.
