A peek at Outlook 2011

2010 has been an year of turbulence and 2011 is no different. Main themes of 2011 are

Equity markets:  10% rising S&P 500 market 
US 10y rates: Rising rates to higher levels but not far from 2010 closing levels
Gold: Gold might see a cap to its further rising
EUR: Euro will be embroiled in core vs peripheral debate

Now my favorite part, volatility markets. Underlying economy is still recovering and turbulent events are anticipated in Europe and China. From this perspective volatility will be slightly higher.

US housing: Forclosures are still happening, Housing starts and new home sales are indicating double dip ahead. Persistent unemployment and dimming of prospects for brighter future is sapping confidence from people. This is not allowing the prices to rise.

EM: Emerging markets are currently battling with inflation, Hot money flows. Inflation rise in emerging markets needs to be treated on a per country basis.  Because, Inflation arises due to various factors, structural problems (institutional), overheating of economies due to unbridiled growth. Ofcourse, most of the policy makers are very much aware of the outright misery caused by Hot money inflows. They are acting on these aspects very well.  Brazil has increased IOF tax to 6 percent. This means higher rates, probably lower equity markets and Stronger currencies.

Gold: Today Gold has achieved the highest currency status driven by fear of  falling dollar. But this has created newer problems in demand side. People from India are slowly staying away from this highly expensive commodity.this structural factor can break the back of Gold price rise.Another factor that can play into this is awareness among investors. 2010 has been an year when investors were scarred by QE and Euro crisis.  Most importantly this reminds me of one thing, In India, in remote villages illiterate people are fooled by quack saints. These impostors take money to pray to rain gods to bring rain into their fields and bring them prosperity. Similarly, in highly educated western world, i see economic bloggers (some impostors) fool the ordinary investors into various investments by telling ghostly stories based on their half knowledge. I strongly beleive this is one of the drivers of the Gold speculation. 2011, gold might see 1500 but might not stay there for long. Gold option trading will be a promising area.

OiL:   OPEC controls the spigots of global oil supply. As long as no geo political shocks due to some terrorism related activity, EM countries should be driving the rise of oil prices.


I am going to write more and more on the macro factors and expressing my trading strategies.

USD swaption skew

Skew in 2010


2010 year dollar fixed income markets weathered various events ranging from hopes in recovery of housing market, Euro currency crisis, Federal reserve’s unconventional methods to handle the crisis of 2008 and geo political events. USD yield curve responds to these events accordingly and rises up when inflation talk takes precedence and falls when safe haven mentality seeps in. Changes in swaption skew reflect these scenarios.

Spot Yield curve is broken down into short dated, 2y, intermediate 5y, medium term long dated 10y and long dated 30y.

Skew is broken down into structures trading 1y and less as short dated, more than 1y and less than 5y medium term and 5y and beyond is long dated.

Players in swaption markets trade options on interest rate swaps to express views on swap rates. In this market Payer swaption and Receiver swaption are akin to call and put on Libor interest rates. Treasury yield curve along with swap spreads will represent the Swap curve on which options are traded. Implied volatility is a measure of dispersion of swap rates at some point in future. High Implied volatility suggests higher dispersion and higher cost of options. Swaption market volatility is depicted more aptly by Normalized volatility. Forward rate times Log normal implied volatility is equal to Normalized volatility.

Normal Volatility = Forward Rate X Log Implied Volatility

Rising Normalized volatility suggests bid for volatility and converse is true for falling normalized volatility.

Interest rates are correlated to Normalized vols. This correlation varies from 1 to -1. In general rising rates will have falling Normalized vols and vice versa. This means a positive correlation. But other factors can weigh in to amplify and depress the correlations. For instance normalized vols for 30y tails are at -0.3.

These factors give a framework of measure to estimate the value in an ATM option.

1) Correlation with rates

2) Volatility ranking

3) Volatility Roll down

4) Carry

5) Implied and realized volatility ratio

6) Implied and realized premium

Skew: Market players attach volatility different from at the money options to Out of the money options. This difference in implied volatility is called skew. Existence of skew is due to demand and supply factors, view of players on the speed of rise and fall in interest rates. Skew dynamics can be abstracted into different kinds of shapes. These shapes are termed as Normal, lognormal, square root, quarter power, super normal and super lognormal skews. These skew shapes are not arbitrary but capture the underlying rates distribution phenomenon.

Log normal skew: level of Interest rates is directly proportional to normalized volatilities. When interest rates are closer to zero, due to zero lower bound rate changes will be lognormal distributed. In this skew, we tend to see, higher normalized volatilities for Out of the money payer swaptions proportional to interest rate level.

Normal skew: level of Interest rates is independent of normalized volatilities. When interest rates are away from zero rate changes will be normal distributed. In this skew, we tend to see, higher flat to similar normalized volatilities for Out of the money payer swaptions and at the money options.

Interest rates move up and down so do normalized volatilities. Swaption skew moves can be traced to moves from one skew level to another skew level. This can be termed as skew migration. Log normal skew can become super lognormal skew that is normalized vols rise fast as interest rates are rising. Similarly, skew can lower to Square root and quarter power. In these two regimes, Normalized volatilities don’t rise as fast as they rise in lognormal regime. After quarter power regime we can think of normal skew level where normalized vols are independent of rate moves. Finally beyond normal skew regime we can think of normalized vols falling when rates are rising.

Spot and forward yield curves tell us about what market is thinking today with current set of information. Volatility players take one step further by trying to guess the range of the yield curve moves with current set of information. This guessing game involves attaching equal probabilities to various rate changes. But reality is far different from ideal state. Some players think rates will go up, others think go down and another group think rates will remain range bound. Markets do what they want and winners and losers are declared accordingly. Due to this kind of market environment, its not accurate to attach equal probabilities when thinking of range of outcomes centered away from the forward curve. Systematic way of attaching higher and lower probabilities to distributions centered on rates other than forward curve is called skew.

Skew arising due to change in market sentiment towards rise or fall of rates can be captured by risk reversal transactions. Risk reversal is defined as buying and selling OTM call and put with same moneyness. For instance, buy ATM + 25 call and sell ATM - 25 put will translate to buying a risk reversal. This strategy is employed to sell rich put skew and buy cheaper call skew and position for rise in rates. This risk reversal price can be compared against price for a normal, log normal skew to identify traded skew.

Skew also arises due to demand and supply in the markets. This factor can be traced by comparing current skew level to historical skew and rate moves and sentiment in the market. Normally flow traders are privy to this kind of information but in no time this information will become public.

Another factor that plays into skew development is when rates move up and down without any particular direction. In other words if high realized volatility persists out of the money option should have higher value than what they normally have. This price can be captured by Butterfly quotes or straddle and strangle swaps. Straddle provides market level for ATM volatility. Strangle will provide indication of Out of the money options. These two quotes combined provide value of the skew for out of the money options.

Demand & supply, Risk reversals and Butterfly quotes together measure the shape of the skew. Indirectly describing how investors expect the volatility to rise. This view is captured by normalized volatility thus resulting in various skew shapes.

SABR Model interpretation of swaption skew.

Skew can be analyzed using SABR model. For detailed discussion of SABR model I will refer to a presentation I put together. SABR model has Rho and nu parameters to capture the Smile and skew of the swaption skews. I looked at NU and Rho parameter for 10y tails from Totem monthly data. Interestingly Vol of vol remained very stable. Month over month yield curve changes had minute effect across most of the maturities. This suggests very low levels of realized volatility in the market. Rho parameter showed changes by becoming positive when rates are rising and negative in falling yield curve scenario. This doesn’t give any predictability to market vols direction but describes the dynamics reasonably.

Short dated skew for 10y tails for different option expiries, 1m, 3m, 6m and 1y expiries manifest skew that is Lognormal to less log normal. As of November month end skew levels are more lognormal.

Does understanding of these skew shapes give us any understanding of how to trade swaptions markets? I think it does. When we clearly understand what has happened we can predict the future outcome with a reasonable confidence. This requires proper description of past and current states and future expected states of market levels.

Yield curve movements-2010

I was doing some research to record the movements in the yield curve in 2010. Therefore i have put together a yield curve graph as of january, june and november month ends. 2010 has witnessed many events. Mainly pertaining to US recovery, Euro core vs peripherals and china and other emerging markets displaying signs of vigorous growth. Of all most important is rise of Gold prices to historical highs. Each of these events played into the changes in the shape of yield curve. Weaker US recovery has been bullish to treasury yields, similarly intensification of Euro crisis led to a safe haven bid.  These two factors played into the fall of yield curve. But as we came close to year end, there is a shift in sentiment of the market players. Yields started rising swiftly. does it mean people are buying into stronger recovery. What has triggered this change. US fiscal deficit widens but the extension of tax cuts is getting greater attention as economists are thinking GDP growth will be boosted by a percentage point.


My prediction for yield curve movements is hinged on same above factors. Weaker US recovery means lower rates. I attach less probability to this so rates have to go higher. Euro will not break up in 2011. We all should remember one thing. Euro project came to genesis from the ashes of second world war.  Europe has been under constant conflagaration through out this millenium. Last 50 years were peaceful years for this continent. Its not that easy to give up this peace. Germany will become stronger by helping the peripheral countries. So any Euro related safe haven bid should be treated as an opportunity to position for higher rates. Another factor that can play into this is how Emerging markets manage their economies. if any crisis erupts here, this will throw a spanner into rates from rising. I forgot two of the main players, Fed QEII and housing recovery. I beleive housing recovery is going to be anemic and slow and will have influence to impede rates fall to rise of rates. Fed QEII will be there as a trump card that can tip all the possibilities in its favor.
Net i beleive we will see higher rates next year compared to 2010.

June 28, 2010 market thoughts

Monday june 28th 2010, a very funny start to the markets. FRB Richmond researcher has published an article stating macro economics is too arcane for people without any formal training. He went on to say people with Phd’s are best suited to render their expertise on the formidable area of macroeconomics. His main intention looks like bashing at blogging world that is bringing transparency to the incomprehensible activities of various stake holders ( fed, politicians and market leaders). Bloggers came back with their rebuttals. All these rebuttals are very much fun to read.


Search for fed economist calling stupid bloggers.

Okay now let us talk some money matters. What happened today in the markets? Bonds staged another rally on the concerns of deflation and stringent measures of austerity talk from G20, Euro came down because of concerns related to Spanish banks, equities staged selloff at the behest of depression kind of feeling in the market.

Bonds: 10 year treasuries have closed at 3.02 %. Rates are in the mode of rally for a while. Entire may rates went down due to the concerns related to sovereign contagion. In june this rally got reversed initially but talk of weaker economic reports is pushing the yields lower and lower. There is a possibility of rates going lower further. Right now market sentiment is very very bullish on rates. Last week we have seen very weak housing report. One thing can put a damper into this rally is change in sentiment, this can be in the form of strong economic reports, ISM and unemployment report. Chances are less likely that a stronger report will emerge.

Now, GDP is driven by consumption and there are no signs of improvement in this factor. Financial crisis of 2008 has altered people’s mind sets from borrow and spend to save and save. Economists say this is not good for the economy. This will lead to deflation. Unofficial Unemployment rate is hovering in double digits. In such a scenario, no one wants to spend the money. Housing is ready to fall to the ground once the crutches of tax credit are expired. Market fundamentals are not at all strong. Every indicator is showing signs of weakness. In this scenario, trade of the day would be bearish trade on equities, bullish trade on bonds and a range bound to down ward bias trade in commodities. In this kind of scenario, European economies suffering from the contagion risk of peripheral countries debt problems are posing another first order risk to growth.

Emerging economies are struggling to break the ugly inflation. I think world is getting into more interesting situations.

US cannot improve its consumption by giving money to consumers. It can improve this by few ways

1) Reducing taxes

2) Building a stronger manufacturing economy

3) Reducing the cost of entitlements.



Reduction of taxes has an amplifying effect on the GDP. I think researchers like Christina romer have contributed their fine minds and effort in analyzing this fact. I don’t want to muddle their well received thoughts with my interpretations. On second and third point I would like to offer my thinking. US has started loosing its grip on manufacturing economy due to increased cost pressures. It takes more dollars to build a car in US than in a developing country. So capital went to these low cost areas and hence US became an economy more dependent on services. Demographics are changing every day. Not every human being wants to become a Harvard law graduate. Some like to live a life of mechanic and some want to become a ice cream maker. These kind of people find jobs with small business owners. Main concern for these small business owners is health care costs. If governments tackle this issue deftly (not sure if Obama care can do this) then people in this sector will get to keep their jobs and they will become bearers of consumption and economy will get kick started. I would implore every leader to work towards an amicable solution to entitlement costs to bring the lower end of society to survive and live life. In the post 2008 crisis recovery, people with good education have gotten improvements faster than the low income groups.

June 23 2010 Highlights

1) Obama named David Petreaus by ordering down McChrystal as his war General


2) Fed came up with cautious outlook for economy.

3) Rates are to stay low forever

4) Long end rates will grind down lower

5) Swaption Skew changes will be favoring receivers

6) Equities will be looking range bound to lower

7) Oil will be range bound



May month has been sovereign crisis issue for Europe, BP gulf crisis for US and inflation global growth problems for Asia. June has been mostly aggravating Gulf crisis in US and equanimity in Europe and currency appreciation in Asia. Towards the end of month new twist came to this drama in the form of replacement of war general in Afghanistan. I think this is more of a political change rather than a strategic change. This act proves obama is very serious about what he means. Okay now what next, is everything all right? NO. Housing sales came low yesterday. Fed came up with cautious outlook and reading same FOMC statement for last 1 year. What does it mean. I can also read the same stuff every month. Why should fed be given such high respect for their acts? It means Fed is viewing the economy through those old rusty indicator lens. Markets are evolved, we have high frequency trading, exotic derivatives, large public sector deficits, persistently high unemployment and huge health care costs. Cocktail of all this well give a hazy picture of some thing being right all the time . This is sufficient for fed to keep rates low etc. Anyway even fed hikes rate nothing is going to happen bank lending. As they have stopped their sacred money long time ago. This means no inflation. This means long end rates have further room to fall or rise slightly.

Swaption skews for receivers are very rich.

Will yuan rise imapacts?

China is running huge surplus against developed countries. China became shop floor of the world. This was made possible by increase in entitlement costs and therefore erosion of competitiveness, improvements in communications and transportation technology, hard work of Chinese labor and political planners. Industries in western countries matured and started providing their workers with huge benefits. Cost of these benefits started tipping the balance of value generated from these industries. Corporate leaders judged for creating shareholders wealth had to scour new ways of reducing costs. Improvements in technology in global shipping and internet have allowed companies to move operations to places where cost of production is cheapest. This resulted in drying up of jobs in manufacturing sector (Middle America) and these jobs moved to eastern side of the globe. This resulted in huge trade surplus. There is one important factor that played role in the de-manufacturing of western countries. It is financial engineering. Western economies have created gigantic consumer societies. These consumers access to credit have gone on binge to finance their purchases of appliances, houses, education, cars and everything. This all was made possible by financial alchemy. Western politicians are asking china to allow their currency to rise. I would say reduce the health care and pension costs. This will tilt the balance of economies. This will reduce unemployment and allow harmony to prevail in the society. Even if china allows yuan to rise to 5 RMB to dollar it is not going to solve problems.
