The USD strengthening since last July is the core driver of the global recession.
The parlor game of the moment is laying odds on the Federal Reserve’s decision to raise rates, leave rates unchanged, or (gasp!) hint at future stimulus. There are certainly a multitude of inputs to the Fed’s decision, and a variety of potential consequences, but only one really matters: the effect on foreign exchange/currency markets.
It’s not that difficult to understand the one dynamic that matters. If the Fed raise yields/interest rates in the U.S., that makes the U.S. currency, i.e. the U.S. dollar (USD), more attractive.

What happens as capital flees emerging markets and China? Bad things. Lots of bad things.
Number 1 Bad Thing: The currencies of emerging market nations weaken as capital flees, forcing the issuing nations to defend their currencies (a losing proposition, as we saw in the Asian Contagion of 1997-1998) or devalue their currencies.
We caught a whiff of what happens when China is forced to devalue the RMB/yuan–global markets went into a free-fall.
Number 2 Bad Thing: Investors sell emerging market stocks and bonds to escape the downside of currency devaluation. This crushes the stock and bond markets in emerging economies–and China, however you wish to categorize it.
Number 3 Bad Thing: Investment in emerging market economies dries up.
