The mysterious and growing divide between the rich and the rest in just about every wealthy country on Earth, including the U.S., is really two mysteries wrapped in one. The first mystery is why real wage growth has sped up at the top and slowed down for everybody else. But the second, more recent, and more fascinating problem is why labor’s share of the winnings in developed economies has been in decline. It’s not just that middle-class wages are falling behind the rich. Overall wages are falling behind something else — capital.

People are becoming less valuable to companies. Why?

All,

I’ve written my first piece in a very long time, this time on the National Debt. I’ve put quite a bit of work into it, and I’d appreciate your thoughts.

All,

Gregory White of the Business Insider has done a fine job with this interview of John Authers, discussing Authers’ new book, The Fearful rise of Markets, and the impact of moral hazard on the financial markets.

Most OTC derivatives are highly standardized, heavily traded products that are more fairly described as unfamiliar than complex.  Nonetheless, a small corner of the market comprised of customized, or bespoke, trades has captured the imagination of both the public and the press. The descriptions put forth to date muddle the scale of the market, purportedly in the hundreds of trillions of dollars, with words like “complex” and “arcane,” all to convey a sense of simultaneous condemnation — the result of some vague concept of inherent mischief — and unholy admiration for the wizards who put these “black boxes” together. In an effort to tone down the more florid descriptions of bespoke trades, what follows is introduction to the market conditions that cause certain market participants to prefer bespoke trades to more standardized alternatives.

Pecking Order

All financial agreements involve mutual promises to deliver assets and/or cash. But some financial agreements limit the scope of assets that can be drawn upon under the agreement. That is, each party has only limited rights to the assets and/or cash flows of the other. For example, assume that A wants to enter into an interest rate swap simultaneously with the issuance of floating rate bonds.  For simplicity’s sake, we will assume that (i) the swap in question is a vanilla fixed for floating rate swap where A pays a fixed rate to A’s counterparty, swap dealer D, and D pays the floating rate on the bonds to A and (ii) the payment dates on the swap are the same as the payment dates on the bonds. This arrangement allows A to pay the bondholders a floating rate, but still manage its interest rate risk by having its payments under the bonds and the swap net out to an effective fixed rate.

But what if the prospective bondholders want to be assured that the swap will not interfere with the credit quality of the bonds? They could insist that A’s payments on the swap be made subordinate to A’s payments on the bonds. That is, A makes payments on the bonds before it makes payments under the swap. This is a basic payment waterfall. This waterfall must be memorialized in both the bonds and the swap agreement, which means that a standardized swap will not do.

In practice, the credit terms of the swap could be much more complex, taking into account various agreements that A has in place, and even differentiate between certain types of payments under the swap, placing each at different levels in the payment waterfall. In short, even the most elementary swap, a fixed for floating interest rate swap, could require intense structuring simply because other agreements require it.

No Market

Another common motivation for bespoke trades is the lack of a market. That is, the risk in question is unique to the party looking to hedge it or too unusual to support a liquid hedging market. For example, assume that A is a heavy oil consumer in town X. Town X is a major delivery point for oil and so there are exchange traded oil futures that track the price of fuel delivered to X. These futures allow A to do a reasonably good job of hedging its exposure to fluctuations in the price of oil delivered to its town X operations. However, A is setting up a venture in town Y which will also consume a large quantity of oil. The price of oil delivered to Y usually tracks the price of oil delivered to X, but can deviate sharply under certain conditions. As such, A would rather not rely on futures tracking delivery to X, but would prefer a hedge that tracks the cost of delivery to Y. A could enter into a swap with dealer D where A pays a fixed rate and D pays the cost of delivery to Y. The net effect of this all-cash swap is that A has locked in a price for delivery to Y.

Further Reading

I’ve written a fair number of articles on the OTC market and related topics, but the well of financial knowledge is orders of magnitudes deeper than the information assembled by this lone wonk. But fret not, because The Qatar Financial Center has set up a simply gigantic resource, QFinance, that is fully searchable and contains information on all corners of finance. It is in essence an encyclopedic compilation of the current state of finance. It seems that most of the entries were written by high level practitioners, with others by academics and regulators. That said, it is a gigantic database, so I have reviewed only a small fraction of the entries. In any case, it is certainly worth checking out.

The internet economic debate du jour is summed up nicely by economist Paul Krugman as follows here:

why [doesn’t] a housing boom — which requires shifting resources into housing — … produce the same kind of unemployment as a housing bust that shifts resources out of housing.

And here:

why … isn’t [ there ] mass unemployment when bubbles are growing as well as shrinking — why didn’t we need high unemployment elsewhere to get those people into the nail-pounding-in-Nevada business?

His point is, on balance, both booms and busts involve the reallocation of resources, yet only busts seem to produce mass unemployment. While Krugman and Arnold Kling* are wrapped up in a debate about how the question influences our understanding of government stimulus, I’d like to simply offer up an answer.

For any fixed amount of capital available for investment, an increase in the amount of capital allocated to one area implies that the amount of capital allocated to some other area must have decreased. In short, capital allocation with a fixed amount of capital is a zero sum game. The same is true of society’s capital. If the pie doesn’t grow, but stays fixed, and society shifts more of its capital into one area of economic activity, it necessarily implies that we have taken capital away from some other activity.

Asset bubbles, however, are, according to my theory of the world, able to temporarily increase the amount of capital society has available for investment because of the effect that asset bubbles have on the market’s expectation of incurring losses on investments tied to the bubble-asset. Some of the capital that society has available for investment is held back by the market in cash or cash-like investments, such as short term Treasuries, in order to cover potential losses that might arise from investments. Some entities, such as banks and insurers, are subject to regulations that dictate how much capital must be set aside to cover these potential losses. Other entities are free to estimate the amount of capital that needs to be held back in order to cover these losses. So, if we took a snap shot of all of society’s capital available for investment at a given point in time, some portion of that would be withheld as a loss reserve in cash or cash like investments. That means some portion of the capital available for investment isn’t really being allocated to “investments,” but being withheld to cover potential losses on bona fide investments.

Asset bubbles create value out of thin air. Price trends develop that deviate sharply from historical norms, and eventually a new, albeit temporary, norm is established. As a result, asset bubbles make the bubble-asset look like a much better investment than it will eventually turn out to be in the long term. As such, asset bubbles create capital available for investment out of thin air because they cause the market to underestimate the amount of capital that has to be set aside to cover potential losses arising from investments tied to the bubble-asset. This means that the effective pie, the portion that actually gets invested in non-cash assets, can be temporarily expanded, removing the zero sum accounting restriction, simply because less of society’s resources are used to cover losses.

When homes across the U.S. all started increasing in value more or less in tandem, home owners felt, and in fact were, richer than they were the day before. They could access the newly found equity in their home to purchase other goods, or double-down and purchase yet another home. As this process escalates and apparent price trends develop, banks feel more confident in making loans tied to housing and begin to compete for those loans. Mortgage lending, which was traditionally considered a “safe” lending business, got even more “safe” since the value of the collateral would surely continue to increase over the life of the loan. So even if the borrower lost his job or his legs, he could always sell the house to cover the loan: there will surely be plenty of equity between the face value of the loan and the price of the home upon sale. And so as lenders’ expectations of an upward trend in price becomes more entrenched, lenders become willing to lend greater amounts of money tied to real estate and can do so without subtracting from other lending activities by simply reserving less capital for losses on their real estate lending.

So what happens when bubbles pop? Once losses exceed expectations, the market is forced to reallocate its capital to cover those losses or face insolvency. If the price of the bubble-asset drops far enough, this could force fire sales outside the bubble-asset market as firms scramble to cover their liabilities. Once this happens, economic actors have less access to capital than they did before the bubble got started, leading to a sharp contraction in economic activity and concomitant upticks in unemployment.

One thing that still puzzles me is why bubbles pop when the bubble-asset isn’t usually expected to produce a cash flow. For example, capital invested in internet companies (e.g., internet stocks) should at some point generate the return that everyone was expecting. When internet startups don’t generate positive cash flows, those returns fail to materialize en mass, and that’s a clear signal to the market that its expectations were off. And so the bubble pops. But what sort of return were people expecting from housing? What was the signal that caused the bubble to pop? Clearly, defaults on bonds backed by real estate were the signal to the capital markets, but what caused the price plateau in the underlying housing market that got the defaults rolling? Was it that credit was extended to the maximum extent possible, and so no further appreciation was possible? Or was the cause psychological, a sort of vertigo price point at which both lenders and borrowers lose their nerve?

*Arnold Kling has proposed an alternate explanation involving the timing of bubbles, arguing that bubbles are gradual while busts are sudden, and that’s the cause. While shocks to expectations are generally bad for markets, I think that this explanation is intellectually unsatisfying because (i) it doesn’t explain why busts are sudden and (ii) it tacitly assumes that sudden changes create unemployment, which is probably true, but is merely descriptive and not explanatory.

All,

I’ve got a new post up on Atlantic Business concerning asset bubbles. Hope you enjoy.

All,

I cannot recommend the following interviews highly enough. John Authers strikes gold again, interviewing Benoit Mandelbrot, mathematician (whom the celebrated Mandelbrot set is named after), and early critic of efficient market theory.

The interviews are available here and here.

The term “naked CDS (Credit Default Swap)” has been tossed around a lot lately, with little to no examination of the etymology of the term. You may have heard of “naked short selling” of stock, and a bit of Google action will tell you that naked short selling is generally illegal. So, you’d be inclined to think that naked CDS must be similar in nature to naked short selling, and inevitably conclude that naked CDS would be illegal but for Wall Street’s tentacles. But of course, you’d be wrong.

Naked Short Selling

Naked short selling has nothing to do with being a hedonistic financier. Ordinarily, to short sell a stock, you (i) borrow the stock and then (ii) sell it to someone else. This pair of transactions leaves you with an amount of cash equal to the price of the stock at the time of the sale and an obligation to deliver the stock to the lender at some time in the future. If the price of the stock drops after the sale, you can purchase the stock in the market for less than the price you sold it for, deliver the stock to the lender, and pocket the difference. Fantastic. Naked short selling is very similar, except you never actually borrow the stock. That’s right, you sell something you don’t actually own. There are circumstances where this wouldn’t be much of a problem (e.g., I don’t own the stock right now but I will in the next couple of minutes) and we might want to allow the practice to occur. But exactly when the practice is acceptable is beyond the scope of this discussion. The key point is that naked short selling involves the sale of an asset you do not currently own.

Naked CDS

A naked CDS position is a short position that is unhedged by the underlying credit risk. For example, I have a short position on a bond through a CDS but I don’t actually own the bond. This means that I profit if the price of CDS protection on the bond increases, which usually means that the underlying bond is more likely to default than when I opened up the CDS trade. Note that I have not sold anything that I don’t own. The equivocation between naked CDS and naked short selling stems from the observation that in each case, you don’t own the thing in question. Sure, but in the case of a naked CDS position, you’re not trying to sell the thing you don’t own.  It is the sale without current ownership that makes naked short selling problematic in certain contexts. In contrast, in the case of a naked CDS position, you simply enter into a trade expressing a negative view on a credit, that is all.

Naked CDS positions are similar to unhedged puts: buying a put on a stock without actually owning the stock. A put gives you the right to exchange stock for a fixed amount of cash, called the strike price. If the market price goes below strike price, you can go and buy the stock from the market, exercise the put, and pocket the difference between the strike price and the market price. Fantastic. So the more the price of the stock falls, the more you profit. How evil. Of course, no one has a problem with unhedged puts, even though they express a negative view on an asset in almost the same way a naked CDS position does. But don’t forget, puts are not part of the “shadow banking system,” or whatever other garbage meme is being pumped this week.

Same Same But Different

Pundits also grumble because naked CDS positions are speculative, as are short positions on commodities, such as the price of fuel. But of course, the custom crafted pundit logic applies differently to different markets. For example, in the context of CDS, naked CDS speculators are bad because they magically cause the price of the underlying bond to decrease. But when it comes to commodities, pundits claim that speculators cause the price of the underlying commodity to increase. They hold this to be true despite the fact that both the CDS market and the futures markets are comprised of an equal number of long and short positions, by definition. Moreover, speculators can make money on both the long and the short end of a trade in either market, so why should we assume they consistently choose the “evil side” of the trade? Why markets with such similar characteristics yield such different criticisms is beyond me, but perhaps one day I too will wield the Möbius strip of pundit logic.

In 2006, few people outside of the derivatives market had used the word “credit default swap” in casual conversation. By 2008, it had become an inescapable household term. People continue to throw around buzz words gleaned from the pink pages of the FT, but as my colleague, Daniel Indiviglio recently asked: Does anyone out there really understand what the Over-The-Counter (OTC) Derivatives market is? Since I consider myself the resident derivatives wonk at Atlantic Business, I felt compelled to respond. But rather than focus on any particular instrument or issue, I thought it would be best to focus on the overall structure of the market – who the people in the market are, what they do, and what relationships they have to each other – and leave the banker-bashing to someone else.

Market-Makers

If you were to base your understanding of financial markets on your experiences as a consumer of financial products, you would probably think that any and all types of financial products are available upon demand – all you need to do is pay for them, right? No. The reason you can purchase stocks over the internet with a few clicks of the mouse is because at the other end of that trade is someone else willing to assume the exact opposite end of the trade. If you want to buy, they’re willing to sell. If you want to sell, they’re willing to buy. The folks that do this are known as market-makers. Simply put, their willingness to both buy and sell assets creates a market in which others can trade these assets.

Liquidity risk is the risk that you won’t be able to sell an asset, or more generally unwind a trade, for an amount of cash close to its expected value at any given moment. So which assets carry the most liquidity risk? As a general rule, the greatest liquidity risk comes from assets in thinly traded markets. That is, the fewer times an asset is traded on any given day, the greater the liquidity risk. For example, stock in Coca Cola carries much less liquidity risk than a Victorian mansion for the simple reason that Coca Cola stock is heavily traded every business day all over the world. As a result, Coca Cola stock trades can be executed quickly through intermediaries who are willing to buy it from or sell it to you, since these intermediaries know that at some point in the near future, someone else will show up at their door asking to buy or sell some more. So these market-makers must be the greatest people on the Earth, willing to devote their time to make markets liquid, all for the greater good of humanity, right? No.  You bought your lunch, even if you don’t remember paying for it. In exchange for providing liquidity, market-makers get to pocket the difference between the prices at which they buy and sell.

A swap is a very common type of OTC derivative, which includes that destroyer of economies, the credit default swap (CDS). While industry folk commonly speak of a buy-side and a sell-side to the swap market, you can’t really buy or sell a swap in the classic sense, since a swap is an instrument in which both sides have obligations to perform in the future. That is, if the underlying rate moves against either party, that party will have to pay up, much like a future or forward contract. This is in contrast to an option from the perspective of its holder. An option grants the right, not the obligation, to the option holder to buy a particular asset; and creates an obligation on the part of the option writer to sell that asset. You can sell a right and assume an obligation. You cannot sell an obligation. Well, there are probably a few bozos out there. But in any case, both parties to a swap could end up having an obligation to pay at some point in the future.

The Sell-Side

Swap dealers are market-makers for swaps: the sell-side of the market. But how do they create markets when you can’t really buy or sell a swap? At all times except execution, swaps have positive value to one of the parties to the swap and negative value to the other. At execution, the market value of the swap to each side of the swap is zero.  This is because the price of the swap will be based upon the value of some rate at execution. One party will be long on the rate (benefiting if the rate goes up) and the other will be short on the rate (benefiting if the rate goes down). After execution, that rate will move, up or down, which will create value to one of the parties. What swap dealers do to net their positions is offset their long positions with short positions; and offset their short positions with long positions. In reality, this process is not so simple. The face value of each trade, known as the notional amount, is not likely to match up so perfectly with the other trades, despite being executed by masters of the universe. As a result, they have to work pretty hard to make all of their trades match up.

The Buy-Side

So who is out there using these swaps aside from those evil useless bankers? Well, I’m sorry to disappoint you, but pretty much everyone: corporations of every variety, particularly heavy consumers of energy products, municipalities of every variety, and of course, hedge funds. There are others, like insurers, who have played a now infamous role in the OTC derivatives market, but the preceding list, while not exhaustive, at least provides some insight into the broad variety of market participants out there using these weapons of mass financial destruction.

So why do these firms voluntarily use these evil, destructive, terrible things which will inevitably cause them to suffer? Well, it’s not original sin. It’s because firms that engage in various types of economic activities have natural exposure to various types of risk. And swaps get traded on pretty much every type of rate you can think of. There are the typical and fairly well known swaps like credit default swaps, which are priced against credit spreads; interest rate swaps, which are priced against interest rate spreads; FX and currency swaps, which are priced against currency spreads; and then there are less well known swaps such as energy, weather, and catastrophe swaps, each priced against their own respective spreads. Liquidity varies across these different categories, for the same reasons outlined above: some are less commonly traded than others. Some swaps, known as bespoke swaps, are never traded at all. They are custom tailored trades designed to hedge the risks of specific parties.

So how do these rates correspond to risk? Taking a position on a given rate, long or short, allows you to assume the risk that the rate will move. If you’re naturally exposed to increasing energy prices, taking a long position on a swap keyed to some energy rate, say the price of oil, will allow you to cash in when the price of oil moves up. Because your business loses money when oil prices go up, the net effect of your business losses and your swap gains are zero, if it’s done right. And what if the price of oil goes down? Then your business does well and your swap does not. Again, if that’s done right, your net position is zero with respect to the price of oil. This lets you forget about the price of oil and focus on your business activities. So who takes up the other end of the trade? Even if a dealer takes on the short position in our example, the dealer will usually find someone else who wants to take the short position of the trade and pass the exposure onto them. So why would this other party want to short the price of oil? There are a number of reasons. They could have the exact opposite business problem that you have, and lose money when the price of oil goes down. Or, they could be one of those evil speculators. Yes, speculators serve a bona fide economic function and actually help make markets more liquid.  Again, sorry to disappoint.

Inter-dealer Trading

Dealers rely on each other to supply liquidity to the OTC market. That is, as mentioned above, it is unlikely that any one dealer’s clients will demand a perfectly balanced set of products. As a result, dealers rely heavily on their ability to trade with each other, and smooth over any imbalances in their books. And because of this heavy inter-dealer trading, swap markets have a lot of inter-dealer credit risk, which means that dealers are exposed to the risk that another dealer will default. In general, counterparty risk, which is the risk that the party you’re trading with won’t pay as promised, is of paramount concern in the swap market. The general market practice is and has been to require your counterparty to post collateral based on daily mark-to-market valuation against the relevant spread. But dealers are so important to the market and their positions are so large that even well-collateralized positions that fail to payout in full can have disruptive, even devastating effects. As a result, a central counterparty (CCP) has been set up, which acts as a heavily capitalized hub through which trades are channeled, and most importantly, netted against each other. Right now, there is only one CCP and it is dedicated to a subset of the CDS market. Other CCPs may very well follow. For more on CCPs, go here.

The image below, which does not take into account any CCP, provides an overall graphical representation of the OTC swap market, with dealers performing the classic bank-style role of intermediary between end-users of financial products.

One thing you should notice about the image above is that the swap market connects otherwise disparate parties in the financial system. This has the beneficial effect of providing each with the risk profiles they desire. But it also has the effect of causing the entire system to assume the credit worthiness of the entire system. In other words, as I mentioned above, swaps create exposure to counterparty risk, which is in essence credit risk. One of the obvious-in-hindsight lessons of this crisis is that counterparty risk is highly correlated to macroeconomic credit risk. That sounds fancy and deep, but really it’s just restating the obvious: counterparty risk is a type of credit risk, and so, as the overall risk of default rises, so does the risk of counterparty default. This means that CDS protection sellers are least likely to payout at the very moment they’re obligated to: upon someone else’s default. That said, the OTC derivatives market – the CDS market in particular – has done a simply incredible job of maintaining functionality through even the worst parts of this crisis and has adapted quickly to increase liquidity and administrative efficiency. While those outside the industry seem convinced there’s some kind of trillion-dollar ruse going on, that is certainly not the case. The OTC derivatives market is an invaluable and remarkably sophisticated market that adds real value to the financial markets and the world’s economies. Without it, our lunch will get a lot more expensive.
