Three Reasons Why Goldman Expects Italian Bond Turmoil To Get Even Worse

As the return of turmoil to the Italian market has demonstrated, the decision by the current Italian government to target a deficit of 2.4% of GDP in each year through 2021 constitutes a meaningful deviation from the commitments made by the previous government to the European Commission of a projected deficit of 0.8% in 2019. The news sent BTP spreads back to the top end of their range since May, with today’s 10-year yield reaching a local high of 3.4%, surpassing the May highs.

And while some commentators see the localized turbulence in Italian markets as exaggerated - especially due to the lack of any 2nd order contagion effects - in a note this morning, Goldman's Matteo Crimella lists three reasons to expect high volatility to persist for the time being:

First, the planned fiscal expansion, while not extreme, is sizable enough to renew investor concerns about the long-term sustainability of Italy’s public debt stock, in large part owing to the expected deterioration in the country’s primary surplus. A lower primary surplus increases the vulnerability of the economy to growth and market shocks, and worsens the outlook for the public finances, especially when the stock of public debt is already elevated and growth is unlikely to benefit much from fiscal easing owing to a low fiscal multiplier. The parliamentary budget office reports that, cumulatively over the past eight years, the government primary surplus has reduced Italy’s debt-to-GDP ratio by approximately 11.5 percentage points. Positive growth and lower interest expenditures (compared with 2011-2013) have also supported the stabilization of the Italian debt level over the past few years (Exhibit 1). With a lower expected primarily surplus, higher funding costs and soft economic activity, considerations of long-term debt sustainability pose a challenge to forward debt/GDP dynamics, and have meant investors have required a higher risk premium on Italian government bonds.


Second, the increase in government funding needs stemming from a higher public deficit comes in conjunction with the slowdown and forthcoming end of the ECB’s net asset purchases. The's ECB quantitative easing program initiated by the ECB in March 2015 is coming to an end this year. Since its initiation, the central bank has purchased €360bn-worth of Italian government bonds and we expect it to buy another €5.5bn in the last quarter of this year. From January 2019 onwards, Goldman expects new purchases to end and reinvestments of the Italian government bond portfolio to average EUR3-3.5bn/month in 2019 (Exhibit 2).

Over the past few years, ECB buying of medium-/long-term debt has allowed the Italian Treasury to increase the average life of government debt by approximately 0.5 years and to bring it back to levels seen before the global financial crisis. Despite an increased reliance on term debt, the Italian Treasury has to roll over approximately EUR400bn in securities per year (including short-term securities). With ECB demand diminishing, the increase in supply to the private sector will likely represent an additional headwind to BTPs.

Third, heightened market volatility in recent months may have had lasting effects on BTP liquidity and market depth. In Exhibit 4, Goldman shows the average daily volumes of Italian government securities on cash secondary markets (M.T.S.) during April, May and June 2018. The volumes of BTPs exchanged in June, following the selloff of Italian bonds initiated at the end of May, have been almost one-third of those observed in April and May.

While these data refer to a few months ago, the collapse in volumes, accompanied by a meaningful increase in bid/ask spreads (Exhibit 5), point to a potentially severe deterioration of market liquidity, which in Goldman's view has resulted in increasingly gappy price action.

In light of these three factors: rising government debt, fading ECB support, and diminished market liquidity, in the short term Goldman expects the volatility of Italian government bonds to remain elevated:

While the broader market seems to have partly moved on from Italy’s risk and international financial spillovers have been relatively muted thus far, we believe the current situation is an unstable equilibrium. After all, the new budget proposal will  likely increase the odds of negative reactions from Brussels and rating agencies, and consequently the risk of additional  volatility and curve flattening pressures.

Finally, while conceding that both the near- and medium-term outlook for BTPs remains highly uncertain, Goldman's best guess for what happens in the near future is that spreads will trade closer to the high end of their range since May for the time being. Specifically, "a move through 300bp in spreads is possible and, if sustained, would likely require a policy change at the national or European level." Who knows, it may even prompt the ECB to delay the December 31, 2018 end date of its QE program...
