Financial bubbles and crises in the world of finance are well-known phenomena that have marked the history of economic volatility. They arise when the prices of financial instruments, shares, real estate or goods rise rapidly above their real value, and are often accompanied by the human factor - speculation and the need for quick profit. Predicting their burst is still quite a mystery. However, there are a number of indicators in today's modern life that help economists to better understand and prepare for potential financial crises. Financial crises come in response to the bursting of a certain type of bubble so they are reflected in the drop in share prices, the withdrawal of investors from the market, losses, bankruptcy and damage to the economy as a whole. Financial technologies are an additional incentive for creation of financial bubbles and because of their simplicity they attract more of different investors. The primary goal of this thesis is to use historical data and prediction models in order to present a conclusion about predictability of crises in the future. The work is based on secondary data sources. When writing the theoretical part of the work, the professional literature of domestic and foreign authors is used, which refers to books, and Internet sources such as scientific articles. Among the methods used in writing the diploma thesis are the description method, the inductive method and the comparison method. The paper provides a theoretical insight into the basic characteristics of financial bubbles, the factors that influence their creation, financial bubble types and forms throughout history. Also, importance is given to regulatory bodies, as well as the consequences of their failure. At the very end, by researching different models, a conclusion will be reached on the possibility of predicting the bursting of financial bubbles and the emergence of potential bubbles of the future.
