Sweden's real-estate industry is behind roughly half the country's traded debt, much of which is issued under a climate-friendly label.
Jyri Suonpää, a green bond manager at Ålandsbanken, says he finds the development "worrying."
Suonpää is keen to see "more issuance from basic industries" but says "a lack of clear rules" such as the European Union's taxonomy is still hampering new supply. That's despite the enforcement of the EU's sustainable finance disclosure regulation, which took effect on March 10.
Nordic borrowers sold more than EUR 13bn of bonds tied to environmental, social and governance goals in the first quarter, a record amount, according to data compiled by Bloomberg.
"ESG is now firmly a key strategic focus area for all large Nordic corporates," said Povl Bak-Jensen, head of the bond syndicate desk at Nordea Bank, which arranged most of the region's deals, including in green bonds.
Companies are flooding the market with issuance because "there is a long-term strategic benefit and most often also a concrete greenium saving to be had," the syndicate banker said, referring to the premium associated with green debt.
Too much risk
But for some investors, Swedish real estate isn't worth the risk. SEB's Mikael Anttila, who manages one of the largest corporate-bond funds focused on Sweden, says he's running a "significant underweight" in the property sector, which represents about 10 percent of the portfolio holdings.
"The prospects for real estate companies can be difficult so typically we avoid that in funds where we have Swedish krona corporate bonds," said Anttila, whose Foretagsobligationsfond has SEK 12bn of assets.
An added worry for Ålandsbanken’s Suonpaa is that borrowers might inflate their green credentials. "I am a little bit afraid of greenwashing in new issues," the investor said.
That's a particular concern if companies rely on ESG bonds to refinance old debt.
"How can I as an investor be sure that the old debt, which is now being refinanced with a green bond, does align with the current principles? My answer is no, it can't," Suonpää said.
Suonpää says that's why he avoided the recent green bond issuance by property company Citycon Oyj.
"In my thinking, I had to pass on that deal."
