Despite the Brexit earthquake and the consequent volatility in most asset classes, investment grade corporate bonds in both Europe and the US managed to post positive returns over June. The very disappointing US May employment report of +38K jobs added (later revised even lower to only +11K) and the phenomenal June report of +287K jobs, have only led to more confusion on the timing of the next Fed rate increase. In addition, the market continues to brace itself for the influx of economic data to properly gauge the initial financial impact of the vote on the UK economy.

• North American and European energy spreads tightened across every rating category in June, with CCC+ rated loans tightening the most.

• June was one of the most active months of municipal bond issuance since 2009, as $45.2 billion of new supply was priced and easily absorbed by the market.
