Will the yen continue to weaken?

Most people think so — analysts polled by Reuters this month predict that the Japanese currency will fall 18 percent against the dollar this year. That will bring the currency to around 102 per dollar from current levels of 98. And all sorts of trades, from emerging debt to euro zone periphery stocks, are banking on a world of weak yen.

Now here is a contrary view. David Bloom, HSBC’s head of global FX strategy, thinks one-way bets on the yen could prove dangerous. Here are some of the points he makes in his note today:

–  Bloom says the link between currencies and QE (quantitative easing) is not straightforward. Note that after three rounds of QE the dollar is flexing its muscles. The ECB’s LTRO too ultimately benefited the euro.

–  The BOJ surprised investors with the scale of its bond buying plan relative to the size of its economy. But Bloom says the Fed has actually tripled its monetary base since 2008 while the Bank of England has expanded it fivefold. The BOJ on the other hand plans to double it over the next two years.

– Bloom calculates that the BOJ plan relative to Japan’s monetary base justifies a yen/dollar depreciation of 15 percent. Instead the currency has fallen almost 30 percent since October.  The yen would have merely moved to 88 per dollar from a November level of around 80, had the market known the BoJ planned to double its monetary base, he says, adding:

For many months now the Russian rouble has been everyone’s favourite currency. Thanks to all the interest it rose 4 percent against the dollar during the July-September quarter. How long can the love affair last?

It is easy to see why the rouble is in favour. The central bank last month raised interest rates to tame inflation and might do so again on Friday. The  implied yield on 12-month rouble/dollar forwards  is at 6 percent — among the highest in emerging markets.  It has also been boosted by cash flowing into Russian local bond market, which is due to be liberalised in coming months. Above all, there is the oil price which usually gets a strong boost from Fed QE.  So despite worries about world growth, Brent crude prices are above $110 a barrel. Analysts at Barclays are among those who like the rouble, predicting it to hit 30.5 per dollar by end-2012, up from current levels of 31.12.

All that sounds pretty bullish. But there are reasons why the rouble’s days of strength may be numbered. First the QE effect is unlikely to last. As we argued here, QE’s impact will be less strong than after the previous two rounds. Analysts at ING Bank point out that in 3-6 months after the launch of QE2 oil prices gained 40 percent, pushing the rouble up nearly 10%. This time oil won’t repeat the trend this time, and neither will the rouble, they say:

Central bankers as carry traders? Why not.

As we wrote here yesterday, FX reserves at global central banks may be starting to rise again. That’s a consequence of a pick up in portfolio investment flows in recent weeks and is likely to continue after the U.S. Fed’s announcement of its QE3 money-printing programme.

According to analysts at ING, the Fed’s decision to restart its printing presses will first of all increase liquidity (some of which will find its way into central bank coffers). Second, it also tends to depress volatility and lower volatility encourages the carry trade. Over the next 12 months these  two themes will combine as global reserve managers twin their efforts to keep their money safe and still try to make a return, ING predicts, dubbing it a positive carry story.

The first problem is that yields are abysmal on traditional reserve currencies. That means any reserve managers keen to boost returns will try to diversify from the  dollar, euro, sterling and yen that constitute 90 percent of global reserves. Back in the spring of 2009 when the Fed scaled up QE1, its move depressed the dollar and drove reserve managers towards the euro, which was the most liquid alternative at the time.
