China is zooming to a record year of corporate-bond defaults, with the 2018 total already more than three-quarters of the previous high even before an expected economic slowdown bites. Chinese companies have reneged on about 16.5 billion yuan ($2.5 billion) of public bond payments so far this year, compared with the high of 20.7 billion yuan seen in all of 2016, according to data compiled by Bloomberg. Strains are set to get worse if the trends of credit-rating companies are anything to go by - agencies including Dagong Global Rating Co. have been downgrading firms by an unprecedented margin. \u201cCorporate profits have worsened this year and are unlikely to improve against the backdrop of an economic slowdown,\u201d Li Shi, general manager of the rating and bond-research department at China Chengxin International Credit Rating Co. \u201cRefinancing will continue to be tough as long as the crackdown on shadow banking continues.\u201d While the People\u2019s Bank of China has made steps to support the flow of lending to companies, many private businesses lack the access to the state-dominated banking system that national behemoths enjoy, and rely on credit from securities tied to wealth-management products and other nontraditional vehicles. Rising yields are set to make refinancing maturing debt all the tougher. Borrowers have missed payments on at least 20 domestic bonds so far this year, according to data compiled by Bloomberg. There was about 66.3 billion yuan of defaulted notes outstanding at the end of May, or 0.39 percent of corporate bonds outstanding, PBOC data show. While still small, that share may be poised to rise. Dagong has reported 13 credit-rating downgrades compared with 10 upgrades so far this year, the highest such ratio on record, according to Bloomberg-compiled data. Results from Dagong peers such as China Chengxin International Credit Rating Co. and China Lianhe Credit Rating Co. show similar trends. The silver lining is that the defaults show Chinese regulators are increasingly comfortable with allowing struggling companies to fend for themselves without official rescues. Ultimately, failures may help provide discipline to providers of credit, and force less productive enterprises out of business. \u2018Necessary\u2019 Defaults \u201cThey are necessary for better credit-risk pricing and will create a healthier bond market in the long term,\u201d Christopher Lee, managing director of corporate ratings at S&P Global ratings in Hong Kong said of defaults. \u201cIt is unlikely there will be a wave of large-scale defaults or concentration of defaults - any such developments will be quickly contained to prevent systemic risks from emerging.\u201d With rising trade tensions with the U.S. threatening to hurt corporate cash flows, the temptation to shore up credit provision may rise. Data over the weekend showed that a gauge of export orders tumbled into contraction in June. An escalation of the trade conflict could add to defaults in China\u2019s financial system, said Jing Ulrich, JPMorgan Chase & Co.\u2019s vice chairman for Asia Pacific. Consumer demand and the wider economy are likely to weaken and that \u201cmay translate into worse credit quality down the road,\u201d she said in a Friday interview in Hong Kong. \u201cThe volume of bond defaults will most likely surpass 2016 and hit a record this year,\u201d said Lv Pin, an analyst in Beijing at CITIC Securities. While most failures in 2016 were from state-owned firms in industries with excess capacity, the majority of defaulters this year have been private-sector firms. With a variety of industries represented, the data show the breadth of the deterioration, he said.
