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.

Addicted to the medicine

It comes as a relief to markets that G20 officials have agreed it is too early to begin withdrawing massive fiscal, monetary and financial support.   However, it is hardly surprising that officials are not formulating an early exit from emergency measures especially given the ongoing uncertainty about the pace and shape of global economic recovery.  

The latest US jobs report did not help clarify the outlook for markets as a smaller than forecast drop in employment in August (-216k) weighed against a surprise jump in the unemployment rate to a 26-year high of 9.7% and downward revisions to past months employment data.

There is a growing possibility that the Fed’s expectation the unemployment rate will breach 10% by the end of the year looks may be hit even earlier.  Fears about a “jobless recovery” will likely increase as a lack of hiring is set to persist for some time yet. 

The absence of any near term reversal of stimulus measures reduces the risk of a “double dip” recession but at some point there has to be a reckoning. Fiscal positions have blown out for many countries and will eventually require spending cuts, higher taxes and/or privatisation in addition to likely increases in the retirement ages for workers, to rectify them. It is questionable how sustainable recovery will be once such measures begin to be implemented.

In the meantime, it is not even evident that policy is working efficiently. Arguably yields on bonds and corporate debt are lower than they would otherwise have been had it not been for central bank actions but lenders are still not passing the additional liquidity to consumers and households against the background of fears about a rising tide of bad loans and delinquencies.

I would compare this to a patient who came close to death and has finally come off life support as the worst passed but has relied on support in the form of various strong medicines to keep him (or her) going.  The risk that the patient has become overly dependent on the drugs has grown but it is highly unclear how he will fare once he is weaned off.  

Fears about the ability of the patient to stand on his own two feet will increase.  The risk that the patient will relapse is intensifying but his ability to pay for more medicine is already diminishing and his options are running out quickly.

Risk gyrations and FX positioning

I must admit it has been quite tough to get a handle on the sharp moves in markets over recent days. Market sentiment shifted from positive to negative and back again in a matter of hours, meaning that anyone wanting to put on a long term trading position has had to have had a significant risk tolerance to hold onto their positions.

Attention was focused squarely on Chinese stocks last week but market fears over tighter regulation eased as the week progressed. Market sentiment was helped by strong existing home sales data in the US, continuing the run of better than forecast US economic data releases. Globally data releases mirrored this tone.

A cautiously upbeat tone from central bankers at the Jackson Hole symposium sets up a positive backdrop for markets. Although Fed Chairman Bernanke noted that the rebound in growth was likely to be slow and ECB President Trichet talked about a “bumpy road ahead” the overall tone was positive.

Importantly there was no indication that a reversal in monetary policy was in sight, with the Fed’s Kohn even indicating that there was no inconsistency between the Fed maintaining low rates for an “extended period” and keeping inflation low. The comments should help to ensure that markets do not misinterpret the signs of recovery as a cue to begin hiking interest rates.

This week’s data slate will maintain the run of good news. However, there are a few risks. Consensus forecasts look for US consumer confidence to improve in August but the weak labour market situation may hold some downside risks for the Conference Board measure of confidence just as it did for the Michigan reading.

US durable goods orders are set to bounce back and new home sales are likely to echo at least some of the gains in existing home sales last week. In the eurozone, attention will focus on the August German IFO survey and this release is likely to mirror the gains in the PMI, with a healthy gain in the headline reading expected.

Risk trades continue will be favoured after overcoming last week’s setbacks keeping the USD under downward pressure but within ranges and risk currencies including AUD, NZD, CAD and NOK under upward pressure. The USD index is verging on testing its 5th August low of 77.428, whist the JPY is also weaker though its moves may be more limited ahead of upcoming elections.

The IMM report shows that speculative investors have cut pared back USD short positions further, but the shift in positioning was relatively small from the previous week, with net aggregate USD short positions at -94.8k contracts compared to -96.1 in the previous week. Notable shifts in positioning over the week include a cut back in net EUR long positions to their lowest level since the week of 5th May 2009.

Commodity currencies suffered some pullback in net long positioning too with speculative AUD and NZD contracts being cut although net CAD long positions did increase slightly. Given the resumption in risk appetite into this week it seems highly likely that positioning will reverse and net USD short positions will increase.

All eyes on Chinese stocks

Equity markets extended their declines overnight as European and US stocks were smacked across the board.  One of the biggest pull backs has occurred in the Chinese stock market where stocks are down by around 17% since early (3rd) August although stocks are still up close to 73% on the year.  Some of this could be on fears of monetary tightening in China as well as missed profit estimates. 

Risk trades were sold and the dollar and yen strengthened whilst bond markets continued to rally.  News that contributed to the move could have included a sharp 35.7% YoY decline in FDI flows to China in July as well as a broad tightening of lending standards in Q2 according to the latest Senior Loan Officer survey by the Fed.  In contrast there was some positive news on the manufacturing front as the US Empire manufacturing survey jumped 13 points to its highest reading since November 2007. 

The Fed announced that the TALF with a capacity of as much as $1 trillion will expire on June 30 rather than December 31 but for other asset backed securities and CMBS sold before January the plan was extended by three months.   This extension failed to prevent a drop in financial shares overnight with the S&P financials index down 4.2%. 

Commodity prices also extended their drop, with the CRB index now down by around 5.6% since 5 August.   This will continue to play negatively for commodity currencies including the Australian, NZ and Canadian dollars, with the currencies looking vulnerable to more downside today.   Expectations of rising oil inventories and a firmer dollar tone are also playing negatively for commodities. 

Some relief may come today from firmer economic data expected in the US and Eurozone.   US housing starts and building permits are set to reveal further signs of stabilisation in the US housing market whilst the German ZEW survey will rise in August on the back of better economic data and past stronger equity market performance.  It is debatable how much economic data can help counter the worsening in equity sentiment but it may at least provide a semblance of relief.  

The dollar index is trading around the top of its recent range and sentiment for the currency has clearly become less negative as reflected in the latest CFTC Commitments of Traders Report which showed a sharp pull back in net aggregate dollar short positions in the latest week.  

Nonetheless, the dollar is likely to show little inclination to break out of its recent ranges against most currencies.  Overall FX market attention will focus on the Shanghai composite to lead the way in terms of risk appetite and overall direction. Thin holiday trading will leave the markets prone to exaggerated moves over the near term.
