Catching up with reality

Markets have had an exhilarating run up over recent weeks.  Since the start of the month the S&P 500 has risen by close to 7%,gaining around 58% from its March low, as the evidence of global economic turnaround has strengthened and the outlook for earnings improved.

Nonetheless, the rally in equities has meant that valuations are starting to look stretched again. For instance the price / earnings ratio on the S&P 500 has risen to its highest level since January 2004, perhaps hinting at the need for a degree of investor caution in the days and weeks ahead.

Other factors aside from the pace of the move also call for some restraint to market optimism such as the potential for escalation in trade tensions between the US and China, the imposition of regulations on banks and the timing of reversal of extreme stimulus measures. 

As the panic has left markets over recent months volatility has eased as reflected in the VIX index which has dropped to around its lowest level since September 2008, just before it spiked massively higher in a matter of weeks in the wake of the Lehman’s blow up. 

This has been almost perfectly echoed in the move in currency volatility, which has dropped to around the levels last seen a year ago for major currencies.  These levels are not quite pre-crisis levels but for the most part pre-date the collapse of Lehman Brothers, reversing almost all the spike in risk aversion that took place from a year ago. 

It is probably not too much of a stretch to state that having expunged the shock of Lehmans and the worst fears about the global economy from measures of risk and volatility the room for further improvements may be somewhat more limited.  This may be countered by the fact that economic data continues to deliver positive surprises relative to consensus, providing fuel for a further rally in risk appetite. 

However, a lot of good news must surely be in the price by now and it is likely that even the most bearish of forecasters has to acknowledge that an upswing in activity is underway. This ought to ensure that consensus forecasts catch up with reality, leaving less room for positive surprises and perversely less support for equity markets. 

The rally in risk appetite and equity markets has taken its toll on the US dollar which has had a gruelling few weeks during which the US dollar index (a basket of currencies versus USD including EUR, JPY, GBP, CAD, SEK and CHF) has hit new lows almost on daily basis.  Any pause in dollar selling driven by a softer tone to equities is likely to provide better opportunities for investors to take short positions in the currency given that little else has changed in terms of USD sentiment.   How far can the dollar drop?  Well for a start the April 2008 low around 71.329 for the USD index beckons and after that its into uncharted territory.

Japanese yen and FX sensitivity to interest rates

Interest rates have some way to go before they take over from risk aversion as the key driver of currency markets but as noted in my previous post, low US interest rates have played negatively for the dollar. As markets have continued to pare back US tightening expectations and US interest rate futures have rallied, interest rate differentials have moved against the dollar. 

The most sensitive currency pair in this respect has been USD/JPY which has been the most highly correlated G10 currency pair with relative interest rate differentials over the past month. It has had a high 0.93 correlation with US/Japan interest rate differentials and a narrowing in the rate differential (mainly due to a rally in US rate futures) has resulted in USD/JPY moving lower and the yen becoming one of the best performing currencies over recent weeks.

Going forward the strong FX / interest rate correlation will leave USD/JPY largely at the whim of US interest rate markets (as Japanese rate futures have hardly moved). Fed officials if anything, are adding to the pressure on the dollar as they continue to highlight that US interest rates will not go up quickly. San Francisco Fed President Yellen was the latest official to do so, warning that the prospects for a “tepid” recovery could fuel inflation risks on the downside.

This echoes the sentiments of other Fed officials over recent weeks and suggests that the Fed wants to prevent the market pricing in a premature reversal in US monetary policy.   It looks increasingly likely that the Fed will maintain interest rates at current levels throughout 2010 given the massive amount of excess capacity and benign inflation outlook, suggesting that interest rate differentials will play negatively for the dollar for several months to come.

As for the yen its path will not only depend on relative interest rates but also on the policies of the new DPJ led government. If Japanese press speculation proves correct the new Finance Minister may favour a stronger yen which will benefit domestic consumers rather than a weaker yen that would benefit exporters. Against this background, markets will largely ignore comments by outgoing Finance Minister Yosano who said that further yen strength would be detrimental for exporters.

The market certainly believes that the yen will strengthen further as reflected by the sharp increase in speculative positioning over recent weeks; net CFTC IMM long yen positions have reached their highest since 10 February 2009. Although USD/JPY has pushed higher since it’s low around 90.21 the upside is likely to be limited against this background and a re-test and likely break back below the key 90.00 psychological level is likely soon.

The best funding currency

The dollar was beaten up over the past week, finally breaking through some key levels against many major currencies; the dollar index touched 76.457, the lowest since September 25, 2008.  The usual explanation for dollar weakness over recent months has been an improvement in risk appetite.  However, this explanation fails to adequately explain the drop in the currency over recent days.   

Although we have seen a multi month trend of improving risk appetite it is not clear that there was any further improvement last week.  On the one hand the ongoing rise in equity markets points to a continued improvement in risk appetite; the S&P 500 recorded its biggest weekly gain since July.  Equity volatility has also declined, reflected by the decline in the VIX index.   

On the other hand, other indicators reveal a different picture.  The ultimate safe haven and inflation hedge, namely gold, registered further gains above $1000 per troy ounce. That other safe haven, US Treasuries underwent the strongest demand in almost 2 years (bid-cover ratio 2.92) for the $12 billion 30-year note auction, whilst the earlier 10 year note auction also saw solid demand (bid-cover ratio 2.77) as well as strong interest from foreign investors.  

The massive increase in bond issuance to fund the burgeoning fiscal deficit continues to be well absorbed by the market for now, whilst the drop in the dollar does not appear to be putting foreign investors off US assets.  The strong demand for Treasuries could reflect a lack of inflation concerns but may also reflect worries about recovery, quite a contrast to the move in equities.

The fact that the Japanese yen and Swiss franc strengthened against the dollar also contrasts with the view that risk appetite is improving.  The yen was the biggest beneficiary currency during the economic and financial crisis but has continued to strengthen even as risk appetite improves.  USD/JPY dropped close to the psychologically important level of 90 last week which actually indicates a drop in risk appetite.  Perhaps the move is more of an indication of general dollar pressure rather than yen strength.  

A likely explanation for the drop in the dollar is that it is increasingly becoming a favoured funding currency, taking over the mantle from the Japanese yen; investors borrow dollars and then use it to take short positions against higher yielding currencies.  US dollar 3-month libor rates fell below those of the yen and Swiss franc for the first time since November, effectively making the dollar the cheapest funding currency and fuelling broad based weakness in the currency.

Although the historically strong relationship between currencies and interest rates has yet to establish itself to a significant degree, ultra low interest rates suggests that the dollar will remain under pressure for a while yet, especially as the Fed continues to highlight that US interest rates are not going to go up in a hurry.
