“Yentervention” (Yen + Intervention) is when a bank (such as the Bank of Japan) intervenes in the financial markets to support the Yen (Japan’s official currency). The intervention could make the Yen weaker or stronger—whatever outcome is desired.
 
The term “Yentervention” has been cited in print sinceat least September 2008, but began to become popularly used in September 2010.
 
   
Wikipedia: Japanese yen
The Japanese yen (円 or 圓, en?) (sign: ¥; code: JPY) is the official currency of Japan. It is the third most-traded currency in the foreign exchange market after the United States dollar and the euro. It is also widely used as a reserve currency after the U.S. dollar, the euro and the pound sterling. As is common when counting in East Asia, large quantities of yen are often counted in multiples of 10,000 (man, 万) in the same way as values in Western countries are often quoted in thousands.

So what’s the conclusion? Well for one the “yentervention” probably wont work long term, and probably wont have the intended impact of boosting exports. And on the signaling side, well, Japan may well be going the way of the US and we may start seeing double on the double-dip front!

Go go BOJ!!!
Acting under pressure from the Government to DO SOMETHING, the Bank of Japan announce a 35,000,000,000,000 Yen ($418Bn) monetary easing program this morning, finally taking that last step and cutting rates to ZERO.  That’s right, the BOJ will literally give you money for nothing (no word yet on whether the chicks will also be free). Ironically enough, though, the logic of giving out free money now is the same as it was in the early 80’s - the BOJ is well aware that:
