The 70-year-old Fed Chairman Powell once again stands in the spotlight of the world economy. This elder, who should be enjoying a leisurely retirement, is now shouldering the heavy responsibility of guiding the global financial markets.

Powell's every public speech pulls at the nerves of countless investors. His words on 'interest rate hikes' or 'no interest rate hikes' sway Wall Street's emotions like a spell. This influence not only reflects his importance as the chair of the Fed but also highlights the complexity and fragility of the current global economy.

However, this power comes with immense pressure and responsibility. Powell needs to find a balance between inflation pressures, the job market, and economic growth, and each decision could have profound impacts on the lives of millions of people.

For ordinary investors, this situation is even more challenging. The market's severe fluctuations not only test their investment strategies but also constantly affect their financial status. In this ever-changing financial world, investors must keep a close eye on Powell's every move in hopes of finding opportunities or hedging against market volatility.

Both Powell and market participants play their respective roles in this grand play of the global economy. The direction of this play will continue to capture the attention of the entire world.
