What could trigger the next economic collapse?

It is worth looking at the history of financial markets to answer this question rather than to rely on economic theories and what is discussed in the media.

The economic collapse of 1929 was due to euphoria and poor regulation of banks and brokers. The crash of 1973 was due to the OPEC oil embargo of Western nations for supporting Israel. The Dotcom bust of 2000 was again due to euphoria in the internet sector. The Great Financial Crisis of 2008 was triggered by sub-prime mortgages held by investors and banks.

The reasons for economic collapses are not obvious before they happen. It is only obvious after the fact. The world has lived through the Korean War, Cuban missile crisis, Vietnam War, oil crisis of 1979, savings and loan crisis of 1980s and countless other events.

Every event may seem like the start of an economic collapse but the stock market sailed through the headwinds.

It does seem like the big one which is coming is the Trade war between US and China, and naturally the rest of the world will suffer because these two players are the largest single economies in the world in terms of import and export volumes as well.

So the ripple effect will definitely be felt across the board. Particularly when the interest rate changes take shape as well... tightening up money supply in the economy.
