Major market swings are all linked to this

While Jim Cramer was celebrating a decade of "Mad Money" on Thursday, he could not forget the central mission of the show. He knows that it is still his responsibility to explain

to investors what happened in the stock market so they can produce a profit. Cramer can clearly see that the rally of the dollar has gripped the worldwide economy and wreaked havoc overseas.

He is especially worried about Latin America, in particular the Brazilian company Petrobras, which at one time had a $350 billion market capitalization. Today, it is only worth $34 billion.

"I mention this seemingly far away situation because it's my job not just to bring you ideas, but to put them in context, explain them thematically, tell you if they can hurt your

pocketbook or your portfolio," said the "Mad Money" host. Cramer saw that almost every large move in the market on Thursday was connected to currency. Almost all of the

global stress was connected to the fact that after a long freefall, the euro finally gained a bit of strength against the dollar. That sent buyers flooding back into the U.S. stock market.

could that be? Fear that the Fed will raise interest rates has gripped the market, and perhaps the retail numbers could persuade the Fed to delay the hike. "If our retail sales are so

weak, then the Fed might not feel pressured to do anything, which means we could get through this period of rapid and worrisome moves without taking a big hit," Cramer said. Cramer

thinks that the market could have a 5 to 7 percent decline if the Fed does the wrong thing and raises rates at its meeting next week. Thursday's big currency moves were so powerful that

most investors even overlooked that one of the largest semiconductor companies in the world, Intel, made a weak pre-announcement. Yet, somehow, the market completely overlooked this
