Guest Post: Why Clearninghouses Are a Maginot Line Against Systemic Risk

Warren Turbeville

As discussed in ECONNED and on this blog, clearinghouses are not a solution to the systemic risk posed by credit default swaps, since there is no way to have a CDS counterparty post adequate margin and have the product be viable (to put it more simply, adequate margin make CDS uneconomic). ..I am one of the few people around who knows something about the clearing business and theory and is not employed by an investment bank or clearinghouse. At the end of my career on Wall Street, I was hired to perform a financial autopsy of the special purpose derivatives clearinghouse set up by California as part of an innovative power market structure. It had failed in the state's power crisis of 2001-02. Observing the tremendous systemic risk generated by using conventional clearing techniques for all but straightforward derivatives, I embarked on a seven year quest. I formed a company that designed a mathematical, IT and legal structure to provide a transparent and orderly system to manage the risks of those derivatives which shouldn't be cleared conventionally. Imagine my surprise when the banks decided against using the system...

Rajiv Sethi: The New Market Makers

...the SEC's preliminary report on the flash crash...led me to believe that most of this activity was caused by algorithmic trading strategies placing directional bets based on rapid responses to incoming market data. Two strategies in particular -- momentum ignition and order anticipation -- were explicitly mentioned as potentially destabilizing forces in the SEC's January Concept Release on Equity Market Structure. The SEC invited comments on the release, and dozens of these have been posted to date. There is one in particular, submitted by R.T. Leuchtkafer about three weeks before the crash, that I think is especially informative and analytically compelling...Leuchtkafer traces the history of recent changes in market microstructure and examines the resulting implications for the timing of liquidity demand and supply...The standard argument against increased regulation of the new market makers is that it would interfere with their ability to supply liquidity. Leuchtkafer argues, instead, that the strategies used by these firms cause them to demand liquidity at precisely those moments when liquidity is shortest supply...

The Day The Market Almost Died (Courtesy Of High Frequency Trading)

A year ago, before anyone aside from a hundred or so people had ever heard the words High Frequency Trading, Flash orders, Predatory algorithms, Sigma X, Sonar, Market topology, Liquidity providers, Supplementary Liquidity Providers, and many variations on these, Zero Hedge embarked upon a path to warn and hopefully prevent a full-blown market meltdown. On April 10, 2009, in a piece titled "The Incredibly Shrinking Market Liquidity, Or The Black Swan Of Black Swans" we cautioned "what happens in a world where the very core of the capital markets system is gradually deleveraging to a point where maintaining a liquid and orderly market becomes impossible: large swings on low volume, massive bid-offer spreads, huge trading costs, inability to clear and numerous failed trades. When the quant deleveraging finally catches up with the market, the consequences will likely be unprecedented, with dramatic dislocations leading the market both higher and lower on record volatility." Today, after over a year of seemingly ceaseless heckling and jeering by numerous self-proclaimed experts and industry lobbyists, we are vindicated...absent the last minute intervention of still unknown powers, the market, for all intents and purposes, broke. Liquidity disappeared. What happened today was no fat finger, it was no panic selling by one major account: it was simply the impact of everyone in the HFT community going from port to starboard on the boat, at precisely the same time...It is time for the SEC to do its job and not only ban flash trading as it said it would almost a year ago, but get rid of all the predatory aspects of high frequency trading, which are pretty much all of them...HFT killed over 12 months of hard fought propaganda by the likes of CNBC which has valiantly tried to restore faith in our broken capital markets. They have now failed in that task too. After today investors will have little if any faith left in the US stocks, assuming they had any to begin with. We need to purge the equity market structure of all liquidity-taking parasitic players. We must start today with High Frequency Trading...

Themis' Take: May 6, 2010 -- The Day That Will Change Market Structure

...The story is not a key-punch error. The story is a failed market structure. The market failed today. The market melted down and ``liquidity providers'' quickly pulled all bids. According to today's Wall Street Journal, high frequency firm, Tradebot, closed down its computer systems completely, as did New Jersey's own Tradeworx,...To make matters worse, while some high frequency firms shut down yesterday and pulled their bids, as we warned they would do for over a year and a half, other high frequency firms turned from being liquidity providers to liquidity demanders, as they turned around and indiscriminately hit bids...The market action of May 6th has demonstrated that our equity market has major systemic risks built into it...The price discovery process ceased to exist. High frequency firms have always insisted that their mini-scalping activities stabilized markets and provided liquidity, and on May 6th they just shut down. They pulled the plug, as we always said they would, and they even admit it in the papers this morning...This is not an isolated incident, and it will happen again.

PLUNGE! 1987 Style Sudden Drop in US Stocks Driven by Program Trading and a Ponzi Market Structure

Jesse

US equities were gripped by panic selling as the Dow plunged almost 1,000 points driven by a cascade of 100 share high frequency program trading, estimated to have been about 80% of volume. Gold rocketed higher to $1,210...This is highly reminiscent of the 1987 crash driven by a flawed market structure based on automated trading and bad theories. The entire stock market rally which we have seen this year off the February lows resembles a low volume Ponzi scheme, and formed a huge air pocket under prices. This US equity rally was driven by technically oriented buying from the Banks and the hedge funds. There was and still is a lack of legitimate institutional buying at these price levels. This was machine driven speculation enabled by the lack of reform in a system riddled with corruption...

Michael Hudson: Bankers Shake Down Congress and the G-20

(CounterPunch); ``all markets are planned, and have been ever since calendars were developed...Most market structures throughout history have been organized in a way that provides the vested interests with a free lunch. This remains the essence of post-feudal capitalism or as some have expressed it, corporativism.''
