NEW YORK (TheStreet) -- Speculation abounds that interest rates could drop despite extremely strong U.S. data, and Jim Cramer brings up his three "black holes" in that regard: the Ukraine/Russia conflict, Japan and China.
Cramer calls Japan "a disaster" after the nation heavily increased taxes, but department store sales are down 10%; therefore, investors should keep an eye on Japan. He adds China could be decelerating more than anticipated, which also worries people.
But Cramer says the Ukraine/Russia conflict is causing the real problem. He believes rich Russian oligarchs are buying U.S. bonds, but more importantly he compares Russia's recent actions with Germany's in 1937 and 1939. Cramer says this sort of international tension will always cause problems.
Cramer is worried about all three of these issues because "every time we go up big, you're going to hear about them again."
