(Bloomberg) -- Overseas investors cut holdings of Chinese sovereign bonds for a fifth month in June, the longest string of outflows on record, as rising US Treasury yields reduce the attractiveness of yuan-denominated debt.

Global funds held about 2.3 trillion yuan ($340 billion) of Chinese government bonds in June, according to data released by the People’s Bank of China. That’s less than the 2.38 trillion yuan of the securities they owned in May, according to official Chinabond data, and marks the longest stretch of monthly outflows since Bloomberg began tracking the data in 2014. 

Overseas demand for Chinese government bonds has waned as the yuan weakened and yields dropped relative to those of US Treasuries, which have risen as the Federal Reserve has raised interest rates to combat inflation.

China’s benchmark 10-year yield rose eight basis points in June, its biggest jump since October, on the back of a record supply of government debt and tighter liquidity. Similar-maturity US yields jumped 169 basis points in the same period as the Fed hiked rates by 75 basis points and signaled the possibility of a similar increase for July. 

Also weighing on the appeal of Chinese debt is the country’s potential plan to boost its fiscal stimulus as it copes with Covid lockdowns and a property slump. That would entail the unprecedented issuance of 1.5 trillion yuan of special bonds for the rest of 2022 and add to existing yuan-debt supply. 

Chinese bond investors may find some relief, with the central bank committing to keeping liquidity conditions ample amid growth headwinds stemming from the turmoil in the nation’s property sector. At the same time, the risk of renewed Covid lockdowns may provide support to sovereign bonds.  

By the end of June, foreign investors’ holdings of Chinese bonds -- both government and corporate -- shrunk to 3.64 trillion yuan or 2.6% of the total market versus 3.1% in January, according to central bank data.

The outflows come as China’s economy grows at its slowest pace since the coronavirus outbreak two years ago. Second-quarter growth was 0.4% from a year earlier, below the forecast of 1.2% in a Bloomberg survey, making Beijing’s growth target for the year increasingly unattainable.
