On August 5, 2024, the stock market witnessed a heart-stopping flash crash, with the S&P 500 plummeting 3% in a single day. The sudden downturn left investors reeling, wondering what had triggered the unexpected drop. While the stock market has since recovered, the ghosts of the event still linger causing investors to ask: what caused this brief but intense market chaos?

To understand the events leading up to the flash crash, we need to explore the complex web of global interest rates, currency fluctuations, and investor speculation. It is a story of how a seemingly isolated decision by the Bank of Japan (BoJ) had a ripple effect culminating in a brief but intense market storm.

In the middle of 2022, the United States of America and most of the world raised interest rates to combat inflation. This policy decision was intended to reduce borrowing, cool down the economy and keep prices in check. However, Japan, who is a significant player in the global economy, bucked the trend. The BoJ kept its interest relatively steady, close to zero. This created an attractive opportunity for investors.

The divergences in interest rates sparked the yen carry trade, a popular strategy among institutional investors. Big money borrowed the cheap Yen, invested in US Equities (like Nvidia stock) and pocketed the difference between the low borrowing costs and higher returns. This trade became a lucrative and speculative venture with many institutions jumping on the band wagon.

Fast forward to August 5 of this year. The Bank of Japan surprised the world with a sudden rate hike catching big money off guard. This unexpected move made servicing the debt more expensive, prompting institutions to scramble and sell assets to meet their debt obligations. What they sold were a combination of speculative assets across the board, such as: Nvidia, Tesla, Apple, Amazon, Bitcoin, Ethereum. That is why nearly every asset tanked that day. This also caused an increase in demand for the native currency of Japan, the Yen since that was the currency required to pay the debt. This demand increase caused a rapid price increase in the Yen making it more expensive, therefore investors had to sell more assets than originally anticipating to cover their costs.

The resulting selling pressure led to the flash crash , leaving markets reeling. The S&P 500 dropped 3% in a single day , a significant move for a market that typically experiences gradual changes. The sudden downturn highlighted the interconnectedness of global markets and the unpredictable nature of institutional investor sentiment.

In Conclusion. the August 5 flash crash serves as reminder of the complex dynamics at play in global markets. As investors, it is essential to stay vigilant and adapt to changing market conditions. By understanding the factors that contributed to this brief but intense market event, we can better navigate the ever-changing landscape of global finance.
