When it comes to sovereign debt, what is the real concern? Level or Liquidity?


What can be added to the happiness of a man who is in health, out of debt, and has a clear conscience?”

Adam Smith

By Elham Saeidinezhad | The anxieties around the European debt crisis (often also referred to as eurozone crisis) seem to be a thing of the past. Eurozone sovereigns have secured record-high order books for their new government bond issues. However, emerging balance-sheet constraints have limited the primary dealers’ ability to stay in the market and might support the view that sovereign bond liquidity is diminishing. The standard models of sovereign default identify the origins of a sovereign debt crisis to be bad “fundamentals,” such as high debt levels and expectations. These models ignore the critical features of market structures, such as liquidity and primary dealers, that underlie these fundamentals. Primary dealers – the banks appointed by national debt agencies to help them borrow from investors- act as market makers in government bond auctions. These primary dealers provide market liquidity and set the price of government bonds. Most recently, however, primary dealers are leaving Europe’s bond markets due to increased pressure on their balance-sheets. These exits could decrease sovereign bonds’ liquidity and increase the cost of borrowing for the governments. It can sow the seeds of the next financial crisis in the process. Put it differently, primary dealers’ decision to exit from this market might be acting as a warning sign of a new crisis in the making. 

Standard economic theories emphasize the role of bad fundamentals such as high debt levels in creating expectations of government default and reaching to a bad-equilibrium. The sentiment is that the sovereign debt crisis is a self-fulfilling catastrophe in nature that is caused by market expectations of default on sovereign debt. In other words, governments can be subjected to the same dynamics of fickle expectations that create run on the banks and destabilize banks. This is particularly true when a government borrows from the capital market over whom it has relatively little influence. Mathematically, this implies that high debt levels lead to “multiple equilibria” in which the debt level might not be sustainable. Therefore, there will not be a crisis as long as the economy reaches a good equilibrium where no default is expected, and the interest rate is the risk-free rate. The problem with these models is that they put so much weight on the role of expectations and fundamentals while entirely abstract from specific market characteristics and constituencies such as market liquidity and dealers.

Primary dealers use their balance-sheets to determine bond prices and the cost of borrowing for the governments. In doing so, they create market liquidity for the bonds. Primary dealers buy government bonds directly from a government’s debt management office and help governments raise money from investors by pricing and selling debt. They typically are also entrusted with maintaining secondary trading activity, which entails holding some of those bonds on their balance sheets for a period. In Europe, several billion euros of European government bonds are sold every week to primary dealers through auctions, which they then sell on. However, tighter regulations, such as MiFID II, since the financial crisis has made primary dealing less profitable because of the extra capital that banks now must hold against possible losses. Also, the European Central Bank’s €2.6tn quantitative easing program has meant national central banks absorbed large volumes of debt and lowered the supply of the bonds. These factors lead the number of primary dealers in 11 EU countries to be the lowest since Afme began collecting data in 2006. 

This decision by the dealers to exit the market can increase the cost of borrowing for the governments and decrease sovereign bonds’ liquidity. As a result, regardless of the type of equilibrium the economy is at, and what the debt level is, the dealers’ decision to leave the market could reduce governments’ capacity to repay or refinance their debt without the support of third parties like the European Central Bank (ECB) or the International Monetary Fund (IMF). Economics models that study the sovereign debt crisis abstracts from the role of primary dealers in government bonds. Therefore, it should hardly be surprising to see that these models would not be able to warn us about a future crisis that is rooted in the diminished liquidity in the sovereign debt market.
