The Real Reason Why There Is No Bond Market Liquidity Left

Back in the summer of 2013, we first commented on what we called "Phantom Markets" - displayed quotes and prices, in not only equities, FX and commodities but increasingly in government bonds, without any underlying liquidity. The problem, which we first addressed in 2012, had gotten so bad, even the all important Treasury Borrowing Advisory Committee to the US Treasury had just sounded an alarm on the topic.

Since then we have sat back and watched as our prediction was borne out, as bond market liquidity slowly devolved then sharply and dramatically collapsed recently to a level that is so unprecedented, not even we though possible, leading first to the October 15 bond flash crash and countless "VaR shock" events ever since.

And while we urge those few carbon-based life forms who still trade for a living to catch up on our numerous posts on market "liquidity" and lack thereof, here is a quick and dirty primer on just why there is virtually no bond market left, courtesy of the man who, weeks ahead of the Lehman collapse when nobody had any idea what is going on, laid out precisely what happens in 2008 and onward in his seminal note "Are the Brokers Broken?", Citigroup's Matt King.

Here is the gist of his recent note on the liquidity paradox which is a must read for everyone who trades anything and certainly bonds, while for the TL/DR crowd here is the 5 word summary: blame central bankers and HFTs.

The more liquidity central banks add, the less there is in markets

• Water, water, everywhere — On many metrics, liquidity across markets seems abundant. Bid-offers are tight, if not always  back to pre-crisis levels. Notional traded volumes in credit and rates have reached all-time highs. The rise of e-trading is helping to match buyers and sellers of securities more efficiently than ever before.
• Nor any drop to drink — And yet almost every institutional investor, in almost every market, seems worried about liquidity. Even if it’s here today, they fear it will be gone tomorrow. They say that e-trading contributes much volume, but little depth for those who need to trade in size. The growing frequency of “flash crashes” and “air pockets” – often without obvious cause – adds weight to their fears.
• Yes, street regulation has played a role — The most frequently cited explanation is that increased regulation has driven up the cost of balance sheet and reduced the street’s appetite for risk, and hence ability to act as a warehouser between  buyers and sellers.
• But so too have the central banks — And yet this fails to explain why even markets like FX and equities, which do not consume dealers’ balance sheets, have been subject to problems. We argue that in addition to regulations, central banks’ distortion of markets has reduced the heterogeneity of the investor base, forcing them to be the “same way round” over the past four years to a greater extent than ever previously. This creates markets which trend strongly, but are then prone to sudden corrections. It also leaves investors more focused on central banks than ever before – and is liable to make it impossible for the central banks to make a smooth exit.
