Infrastructure debt risk-return: low defaults, high recoveries and a spread pick up vs comparable corporates

Infrastructure debt has a superior risk-return profile vs comparable corporate credit. This is due to lower loss rates and higher spreads relative to corporate bonds

Spring 2017

7 March 2017

Infrastructure debt has traded at a spread premium to comparable corporates since the aftermath of the financial crisis and global recession of 2007-09. Much of this is due to banking capacity being withdrawn from the infrastructure market because of banks having less capital available to fund long-dated projects. This, in turn, is due to Basel III, which significantly increased the quantity and quality of capital banks must hold, decreased their leverage limits and increased their minimum liquidity.

Basel III and bank stress tests have resulted in less bank funding for infrastructure

Basel III fundamentally changed the environment in which banks operate by requiring more capital, more liquidity and more stable funding – all sensible measures, but measures that resulted in less bank funding capacity.(1) Common Equity Tier 1 capital (CET1) increased from 2% of risk-weighted assets (RWA) under Basel I and II to 7% under Basel III. Tier 1 capital increased from 4% to 8.5% and total capital increased from 8% to 10.5%.(2) Under Basel II, CET1 used to be referred to as Tier 1 capital or core capital.

There are also two new capital buffers being phased in: a mandatory capital conservation buffer of 2.5% designed to give a cushion during an economic downturn, and a counter-cyclical capital buffer of 0.0-2.5% intended to shield banks during times of excessive credit growth. The level of the counter-cyclical buffer is set by each national banking authority. There are further capital surcharges for systemically important banks and for Pillar 2 risks such as operational risk. In total, banks are likely to target total capital of 13-15%, a significant increase over the pre-crisis days of 8%. 

Basel III further introduces a maximum leverage ratio of 3% to prevent an excessive build-up of leverage in the banking sector. This means that a bank’s total RWAs should not be more than 33x its Tier 1 capital.(3) It is meant to be a credible “back-stop” measure to the new risk-based capital requirements described above. There is also a new 30-day Liquidity Coverage Ratio (LCR) designed to cover short-term outflows and other demands for cash. In the LCR test the amount of high quality, liquid assets has to be 100% or more of expected net cash outflows (NCOs) over the forthcoming 30 days. 

The effect of the leverage test has been reduced lending, especially in areas outside a bank’s domestic market. This has been observed in a number of jurisdictions where banks are not lending outside their home market. It has also pressured banks to sell low margin assets (e.g., infrastructure). The effect of the LCR test has been for banks to hold significantly more liquid, low yielding assets and fewer illiquid, longer-dated assets (e.g., infrastructure). 

Exhibit 1. Infrastructure debt spreads are wider and much more stable than corporate bond spreads

The net effects of Basel III and the US and EU bank stress tests imposed since 2009 have led to a shortage of bank capital available to fund infrastructure. At the same time governments around the world are calling out for more infrastructure spending. The result has been an infrastructure spread premium over comparable corporate credit since 2010, as shown in Exhibit 1. Investors are beginning to step in to take up the slack.

Illiquidity premium over bonds

Infrastructure loans are less liquid than infrastructure bonds. To determine the illiquidity premium, we assessed 235 infrastructure bonds in the European market and compared their spreads to the senior infrastructure loan market. As can be seen in Exhibit 2, the illiquidity premium ranges from 75 bps to 125 bps+.(4)

Exhibit 2. Illiquidity premium: infrastructure loans versus bonds

We feel some of the spread premium of infrastructure is due to a complexity premium as well an illiquidity premium, although this is more difficult to discern from the data. Infrastructure is a creature of contracts and availability and/or demand-based payments. The analysis is unlike traditional credit. Not many investment managers are properly experienced to assess infrastructure risk.

Moody’s global project finance and infrastructure study

Even though infrastructure trades at a spread premium over corporates of similar credit quality, the default, recovery and loss rate data is very favourable for infrastructure.

Moody’s conducts an annual study of project finance loans. It now covers a 32-year period and is a global study covering the developed and the emerging markets. Moody’s most recent March 2016 study covers 5,880 project finance loans. This is their full data set.

As part of the study, Moody’s also has an annual Addendum, the most recent of which is September 2016. This now covers 1,890 broad infrastructure loans, the largest sub-set of the study. Within broad infrastructure, Moody’s breaks down the market into an infrastructure industry sector, which consists of global transportation and social, and a power industry sector, which consists of power transmission and distribution. The 1,890 broad infrastructure loans include 1,730 loans from global transportation and social, and 160 loans from global power transmission and distribution.

Infrastructure default probability drops over time

Several of the main conclusions from the study and the Addendum are listed below and illustrated in Exhibits 3 and 4:

  • Average annual default rates 0.49% for infrastructure vs. 0.64% for project finance in general.(5) This is much lower than Ba1 corporates at 1.05% and still lower than Baa3 corporates at 0.54%.(6)
  • Credit quality improves over time: by year five infrastructure credit quality is substantially better than that of Baa3 corporates and by year six it is consistent with A rated-corporates.
  • Marginal default rates drop after year two due to projects moving from construction to operation and de-leveraging because of amortising loans. Average improvement in credit quality is from high Ba to mid-single-A (i.e., five notches) over six years.
  • Unlike corporates, infrastructure recoveries are largely independent of the economic cycle.

The third point encapsulates the most important characteristic of infrastructure debt: that the probability of default decreases over time, unlike investment grade corporates where the probability of default increases over time (see Exhibit 3). This is because strong corporate issuers refinance and there is an ever increasing weak cohort of issuers. We feel this aspect of infrastructure debt is undervalued by the market.

Infrastructure debt has strong recovery rates and low loss rates

According to the same Moody’s study, infrastructure debt has higher recoveries than comparable corporate bonds and much more certainty in recovery levels as shown in Exhibit 4. Even though the mean recovery for broad infrastructure is 80.5%, the mode is 100%. That is, the most frequent recovery is 100%.

Exhibit 4. Infrastructure debt recoveries and loss rates

The loss rates for infrastructure can be inferred from the data in Exhibits 3 and 4 and they are very low vs. comparable corporates. Taking (1 - the mean recovery rate) x the default rate or (1 - 0.805) x 0.49% gives a historical loss rate of 9.6 bps per annum (pa) for infrastructure. The same calculation for Baa3 corporates yields (1 - 0.467) x 0.54% or 28.8 bps pa and for Ba1 corporates it is 56 bps pa, materially higher than for infrastructure. We compare infrastructure debt to Ba1 and Baa3 corporates because most infrastructure, although unrated, would be rated Ba1/Baa3 in the first four years after financial close, according to Moody's. The credit quality then climbs to mid-single-A by year six.

Infrastructure is an undervalued asset class relative to its risk

We feel this data supplies solid evidence that infrastructure debt is an undervalued asset class relative to its risk. The analysis shows that infrastructure debt trades at a wider spread premium to comparably rated corporates yet has lower loss rates. Much of this premium is attributable to the lower amount of bank capital available to fund infrastructure and an illiquidity premium. Given that our funds employ a buy-and-hold strategy, the illiquidity premium is a source of alpha and it is something we want to capture for our investors.
