Shanghai Chaori Solar Energy Science & Technology had earlier announced in a stock market filing that "due to various uncontrollable factors", the company might not be able to make an 89.8 million yuan ($17.1 million) interest payment in full on Friday last week. The company failed to make the full coupon payment.
Chaori Solar sold 1 billion yuan of five-year notes called the "11 Chaori Bond" in March 2012 with a variable annual coupon, starting at 8.98 per cent. Annual interest is due on March 7 every year. Investors have the right to sell the bonds back to the company at par in March 2015.
Chaori Solar encountered significant losses and financial difficulties over the past three years, as the solar power industry in China experienced a serious overcapacity problem and falling prices for photovoltaic cells, while the Government has been embroiled in a trade war with the US and the EU.
"Overcapacity in the Chinese solar industry resulting from cheap financing and excessive local government support has led to sharp price fall in solar materials between 2009 and 2012," said Bank of America solar analyst Robin Cheng.
"Since 2012, the Chinese Government has been sending signals to the market that it would stop funding unprofitable players and encourage consolidation."
The bond is listed on the Shenzhen Exchange but trading was suspended last July after Chaori Solar experienced two consecutive years of losses. Chaori Solar last week reported a net loss of 1.33 billion yuan for 2013, its third straight annual earnings deficit.
Last year, Chaori Solar narrowly avoided a bond default after a local government in Shanghai persuaded banks to defer claims for overdue loans, which enabled the company to meet interest payments.
Some Chaori Solar bondholders plan to complain to the Shanghai Fengxian local government and "express their anger" at its not aiding the company, the 21st Century Business Herald reported.
Most analysts view the lack of defaults in China's onshore bond market as unusual, and see a potential onshore bond default as having positive implications.
"We think it's a good thing, as a normal economy needs defaults to better price bonds and other debt products," Ting Lu, a China economist, and other analysts at Bank of America wrote in a research note.
"Defaults of some debt products are not on a similar scale to a collapse of a major financial institution."
China's corporate bond market, the world's third-largest after the US and Japan, totalled 8.7 trillion yuan at the end of January compared with 800 billion yuan at the end of 2007, according to Bank of America estimates.
David Cui, China strategist at Bank of America, pointed out that the Chaori Solar bond in question is backed by a local government and an underwriter with ample resources to bail out investors. "If the bond is allowed to default, we believe it will ... be because the Government wants to teach the market a lesson and address the implicit guarantee moral hazard issue," he wrote in a report.
Letting Chaori Solar default "will help go some way to correct the moral hazard problem in China's financial sector, and that is positive for the long-term development of the onshore bond market", Zhiwei Zhang, a China economist at Nomura, noted.
Fitch Ratings said a default would be "positive for the market in the long term as it will instil greater discipline to price credit risk more effectively."
"In the recent years, local governments have intervened several times to prevent defaults in the onshore corporate credit market in order to maintain economic and social stability.
"That the Chaori [Solar] default has been allowed to emerge may signal a shift in the Government's stance toward a greater tolerance of outright corporate defaults," Fitch said.
Chaori Solar's bonds have a large retail investor base, which makes the case even more noteworthy.
Chaori Solar's default warning coincided with the annual National People's Congress, a meeting of China's political leadership. China set its gross domestic product growth target for 2014 at 7.5 per cent, as expected.
But it seems like a mission impossible to achieve every task outlined in Premier Li Keqiang's speech without compromising on the growth target, said Yao Wei, China economist for Societe Generale.
"In other words, in order to hit the growth target, debt risk will probably build further and/or reform progress may suffer," Yao said.
"2014 will be the year China seriously cleans up mounting local government and corporate debts, which have been rapidly accumulated since late 2008," the Bank of America analysts said.
"We believe the chance of some bond and trust loan defaults will rise significantly in 2014, especially as the more confident Government sees the need for some defaults to develop a more disciplined financial market," they said.
