China's central bank, the People's Bank of China (PBOC), is taking steps to calm the bond market as traders have set red lines for 10- and 30-year yields at 2.25% and 2.45% respectively, expecting the PBOC to intervene if those levels are breached. The central bank has reportedly hundreds of billions of yuan in securities to sell.
Meanwhile, Beijing is studying shifting to a short-term rate as its new policy tool, making the existing one-year benchmark rate endangered. The PBOC announced plans to conduct bond repurchase operations in the afternoon, narrowing volatility around the seven-day repurchase rate and strengthening expectations for it to become the new policy.
Financial institutions are buying Chinese government bonds, which some experts believe indicates expectations of lower interest rates in the future. This behavior can be seen as shorting the Chinese economy and increasing pressure for capital outflows. The PBOC has expressed concerns about the bond market and introduced plans to sell treasury bonds to cool a bond rally.
The central bank's goal is to stabilize exchange rate and economic expectations.
