i) Euro Investment Grade Bond Index: Corporate Spreads

The period from late 2007 through to Q1 2009 coincided with the greatest widening in credit spreads ever seen. The excess systemic leverage/structured product bid leading to very tight spreads markets in the preceding 2003-2007 period was spectacularly undone.

We recovered hard in 2009 once the central bank easing began with money looking for a home in cheap, high yielding corporate bonds. 2009 coincided with the greatest spread tightening era ever seen.

While corporate bond markets sold off in late 2011-2012, we have seen a good recovery since. The compression trade, between high and low beta corporate bonds all the way down to and including the HY market was a key feature in the 2012-2014 years and the ECB QE-related 2016-2017 period.

False start

Fragile trade truce get us off to a weak start... It looks like markets had gotten ahead of themselves. The hopes of a Brexit deal are looking more precarious again, with the EU once again reportedly playing hardball. The potential for a US/China 'limited' trade deal has underwhelmed so far, but at least we might have something which might help calm the tensions. But the [...]

Tunnel of love

Green light and it's a go... In a flash, the tone is massively upbeat. Trade tariff talks have apparently gone well between the US and China and we are in de-escalation territory. Meanwhile, we have the makings of a deal on Brexit and markets rallied hard into the final session of last week as a result. Should the positive tone follow through into some sort of reality of [...]

Signs of progress

But too much to juggle... We're not out of the woods in any way but we have let some much needed steam out of the pressure cooker. Trade talks/Hong Kong/Middle East/Brexit/macro were all beginning to get too much and were clearly weighing on markets. So some of the heat has been let out courtesy of - or hope that we will see - some sort of breakthrough (a partial deal?) on t [...]

Boris’ Karloff moment

Now we're talking... The focus totally should have been CK Hutchison Telecom's six-part deal, with investors scrambling to get hold of the company's debt even as Hong Kong's troubles show no sign of abating - but markets were stumped. By Brexit. The latest had the markets in a tizzy as talks were said to have broken down (or close to breaking down) amid an apparently terse p [...]

ii) Investment Grade Bond Index: Corporate Spreads 2015-

Investment grade spreads as measured by the iBoxx IG cash index widened by 76bp in 2018. There were hints of a crisis for equities coming from slowing macro and a cacophony of geopolitical situations, and while credit managed to stay clear of a direct hit, the asset class got dragged into the weakness.

It was the poorest year for widening since 2016, but the worst since 2008 for total return performance as we returned -1.2%.

However, in 2019, all risk assets have rallied. Equities have typically put on 15%+ (to end September), but fixed income assets have had a tremendous time of it as well. IG spreads have tightened 50bp in this period, and returns have come in at almost 7% for the opening 9-month period.

We’re not at record lows (B+83bp) and are unlikely going to get there in 2019 (currently at B+124bp, Oct 2019). However, the ECB is back in play from November and its QE purchases might offer bit a push into year-end.


iii) Investment Grade Bond Index: Corporate Yields

We’ve seen a crunch lower in index yields in 2019. It has predominately been driven by the rally int he underlying, but credit spreads have tightened too. From 1.62% in January 2019, we saw a record low index yield of 0.38% in August. The weakness in government bond markets in September saw those yields back-up to 0.54% at the beginning of October.

The rally has boosted returns for all fixed income asset classes. More importantly, for credit investors, in so far as refinancing helps keep the default rate low (extending maturities), the lower yield environment has boosted issuance. We’re heading for a record IG non-financial deal total in 2019, while the high yield market and senior debt issuance volumes are at higher levels than average.
