Stock Market Volatility Is Coming. Here's How to Survive It.
What Is This Article About
This article breaks down my “ThougTHs” about Japan's currency, the yen. The yen just hit its lowest value in 40 years. This is not just a Japan problem. It is starting to touch American mortgages, stocks, and interest rates too. This piece explains what is going on, why it started, and what a normal person should do about it.
What Is Happening
The Japanese yen has crashed to its weakest level in four decades. Japan stepped in to stop the fall. They sold US dollars and used that money to buy back their own currency. This is called a currency intervention. It is a rare and drastic move.
Japan also happens to be the largest foreign owner of US government debt, known as Treasuries. When Japan sells dollars, it also ends up selling Treasuries. That sends shockwaves through the US bond market. US banks have already been told to prepare for more of this.
Why It Is Happening
For years, traders ran a strategy called the "carry trade." Here is how it worked. You borrow yen at a very low interest rate, close to zero. You convert that money into dollars. You put those dollars into US Treasuries, which pay a much higher interest rate. You pocket the difference.
This worked well for a long time because Japan's rates stayed low and the yen kept losing value against the dollar. But once the gap between US and Japanese interest rates got too wide, and the yen got too weak, the trade started to break down. Investors began rushing to sell yen-funded positions, which made the yen crash even harder.
What Has Caused This
Two things collided. First, the US fought record inflation in 2022 and 2023 by raising interest rates faster than almost any time in history. Second, Japan has dealt with decades of deflation, an aging population, and weak demand, so it kept its interest rates near zero just to keep its economy moving.
That created a massive gap between US and Japanese interest rates. Money flowed out of Japan and into US dollars to chase the better return. Over time, this pushed the yen lower and lower until Japan felt forced to intervene directly in the currency markets.
How Will This Affect Americans
When Japan sells US Treasuries to raise cash for its currency defense, it adds a flood of supply to the bond market. More supply pushes bond prices down and yields up. Higher yields mean higher interest rates across the board.
That shows up in daily life as higher mortgage rates, higher rates on car loans and credit cards, and more expensive borrowing for businesses. It also puts pressure on stock prices, since higher rates tend to make stocks less attractive compared to safer investments like bonds.
How Will This Affect the Rest of the World
Global economies are tightly connected. Japan is not the only country selling US Treasuries right now. Other nations are doing the same because they are dealing with their own inflation, often driven by rising oil prices. Demand for US bonds has dropped to a 10-year low.
This is a global chain reaction. One country's currency problem can push interest rates higher everywhere, which slows down borrowing, spending, and investment worldwide.
How Should a Normal American Citizen Be Prepared
Nobody needs to panic, but it makes sense to be alert. Expect more volatility in the stock market over the coming weeks. Expect interest rates on loans and mortgages to stay elevated or possibly rise further. This is a good time to understand your own exposure. Know if you have variable rate debt, know your emergency savings situation, and know how much of your portfolio is sitting in one place.
What Should They Expect
Based on the last time this happened, in 2024, the pattern tends to repeat. Japan intervenes, the yen bounces for a few weeks, and then it slides right back down because the intervention treats the symptom, not the root cause, which is the interest rate gap between the US and Japan.
There are really only two ways this resolves. Either the gap closes slowly, with Japan raising rates and the US lowering them over time, or it closes suddenly, which could trigger a sharp, fast downturn in markets. The next major checkpoint to watch is September 16th, when the Federal Reserve is expected to make its next interest rate decision.
What Should They Do to Mitigate the Impact
A few sensible steps: keep an emergency fund so you are not forced to sell investments during a downturn, avoid making big emotional decisions based on short-term headlines, stay diversified rather than concentrated in one stock or sector, and if you are planning to borrow money soon, like for a mortgage or car, factor in that rates may stay high for a while longer. Long-term investors historically have been rewarded for staying invested through volatility rather than trying to time an exit.
Future Action Items
Keep an eye on a few dates and signals in the weeks ahead: the Federal Reserve's September 16th meeting, any further emergency interventions from the Bank of Japan, movement in the US 10-year Treasury yield, and the dollar-to-yen exchange rate. These will show whether this settles down or escalates.
