China weighs tax on bond interest income

China is assessing the impact of introducing a 25% income tax on interest earned from central and local government bonds, a move that could influence a market where yields are hovering near record lows. The potential levy would align the tax on such interest with the standard corporate income tax rate and could lift sovereign and local bond yields from historic levels.

The initiative is currently at a consultation stage, with authorities gathering feedback from financial institutions rather than announcing a policy change. The focus is on how a new tax on interest income would alter investor behavior and pricing in the government bond market.

The People’s Bank of China conducted a survey last month that included a number of lenders to gauge market reaction to a possible 25% tax on interest income from their central and local government bond holdings. Banks were asked to estimate how their appetite for these securities would change under such a regime.

Specifically, lenders were requested to indicate whether their willingness to hold government bonds would decline by less than 10%, 20%, 30%, or more than 30% if the tax were imposed. This structured response framework is intended to help authorities quantify potential demand shifts under different scenarios.

The survey is exploratory and does not indicate whether or when existing exemptions might be removed; it signals that policymakers are actively considering how tax policy could be used alongside low yields.

At present, both enterprises and individuals in China are exempt from income tax on interest generated from central and local government bonds. Ending the corporate exemption for such interest would bring the tax treatment into line with the 25% standard corporate income tax rate.

Any change to this framework would therefore mark a notable shift in how government bond income is treated relative to other corporate earnings. The survey process is focused on understanding how removing the exemption could affect institutional investors that hold significant volumes of sovereign and local debt.

Huatai Securities estimated that if a 25% interest income tax were fully priced into the market, the 10-year sovereign bond yield would theoretically need to rise by 52 basis points to maintain current after-tax returns for investors. Even so, the firm suggested that actual yields on newly issued 10-year government bonds might increase by only 10 to 20 basis points.

Guohai Securities projected a similar upward effect on local government debt. It estimated that 10-year local government bond yields would theoretically need to rise from 1.68% to 2.25% to offset a 25% tax on interest, while noting that the real-world impact on yields would likely be smaller than the theoretical calculation.

In terms of investor obligations, Huatai Securities estimated that applying a tax to interest on existing bond holdings would result in an additional 459 billion yuan in annual tax liabilities for institutional investors. This underscores the scale of the potential change for entities heavily invested in government bonds.

The policy review takes place against a backdrop of government bond yields that are near record lows. In this environment, even moderate adjustments to the tax treatment of interest income could influence both the level of yields and the demand for sovereign and local government securities.

By exploring a tax on bond interest income, authorities are examining how fiscal tools might interact with monetary conditions in the government debt market. The ongoing survey suggests that any decision will be informed by detailed feedback on potential changes in investor behavior and market pricing.
