The big news this week is the Federal Reserve’s rate-setting meeting tomorrow and Thursday. This is one of eight meetings held each year, approximately every six weeks. The remaining ones in 2015 are in October and December. The reason this matters is because, once again, the Fed has to decide whether to start raising rates or not. I have argued before that, economically, it doesn’t really matter that much, but from an investor confidence perspective—and thus for the markets—it does.

August was the worst month for U.S. markets in more than three years, so say the headlines. I suspect it was also the worst month in at least that long for many international markets as well. And, as today’s numbers show us, we aren’t done yet. As I write this, U.S. markets are down about 2.5 percent, and European markets closed down around 3 percent.

Now that things seem to have calmed down a bit, it’s a good time to discuss why the past week has been so turbulent. The usual explanations—the Chinese currency devaluation and stock market crash—are certainly valid, but there’s more to the story. Let's take a closer look at the connection between the news from China and U.S. stock prices.

One bad day doesn’t make a bear market. Two bad days, however, and the prospect of more to come, may well signal one.

It turns out that China’s stock market remains a market after all, despite the Chinese government’s best efforts. Prices on the Shanghai Composite Index fell 8.5 percent on Monday and another 1.7 percent Tuesday, stripping away more than half of the gain since the last bottom.

Yesterday wasn’t a good day for the stock market—anywhere. When I wrote yesterday’s post, the U.S. markets were only off by a bit. But the drop later in the day looked like it might be a bad sign; at a little over 2 percent, it was the largest one-day dip in some time.

Today, I want to revisit a post I wrote just over two years ago. I’ve updated some of the data, but the concerns and the conclusions remain timely. In keeping with one of my recurring themes, this is also an example of how rising interest rates won’t mark the end of the world but, rather, a return to a more normal environment.

Yesterday, I talked about several major trends that are poised to at least pause (and quite possibly reverse) over the next couple of decades. One major area we didn’t discuss is Europe, which is likely to see more change in the next 5 years than it has in the past 20.

Yesterday, I saw an interesting doom-and-gloom piece on rising rates, which claimed that rate increases typically sink the stock market and that we could potentially expect a crash in the near future.
