Yen Carry Trade May Return.

Japan had lost the race to the bottom against the US. " Ben, Ben, he’s our man / if he can’t print ‘em / no one can! "

As the risk of yen revaluation in deflationary Japan exceeded the risk of dollar inflation in the US -- where the Fed declared its intentions to have inflation rise and then abjured responsibility for inflation when it did rise and as Japan’s customers were forced into “must-do” trades for buying the YEN to pay their Japanese suppliers -- why would anyone take the risk of borrowing the yen when they could borrow the dollar instead?

Now the US is faced with the situation where the G-7 central banks have arrested the upward spike in the yen threatened after the country’s disasters and affirmed the old highs just under 80 as resistance. The net result of this move is a global borrower can now borrow the yen without fear of further revaluation!

The Dollar Carry Into the Yen

If we turn the trade around and look at the two components of the dollar carry into the yen, the interest rates spread and the spot rate return, we can see just how meaningless the interest rate component has been since the US went to a zero interest rate policy in December 2008. The spot rate return on borrowing the dollar and lending the yen has moved higher as Japan has been unable to break away from its deflationary miasma while the Federal Reserve has convinced investors the US will, one day, defeat the deflation that never existed.

Reviving the Yen Carry Trade

If the US does adopt an exit strategy from QE2 and the dollar becomes more expensive to borrow while the yen is not at risk of running away to the upside, the wider interest rate gap between the US and Japan will make Japan the preferred funding source once again. As noted last November, this has not been the case since the financial crisis; we can match the carry return of the dollar into a basket of emerging market currencies quite closely, but the yen carry trade has been irrelevant.

Where does this lead? If the dollar carry seized the baton from the yen carry trade and allowed all manner of emerging market assets to shoot higher in 2009 and most of 2010, then the yen carry trade can return the favor and finance the US should the Federal Reserve adopt an exit strategy. US would tighten; they would un-tighten for the US.

That would be quite bullish for US financial assets should events unfold this way.
