As a portfolio manager, you are tasked with evaluating the implications of economic growth rates on bond market performance. Recent reports indicate that the country's GDP growth is projected to slow down significantly over the next year due to anticipated changes in trade policies and increasing inflationary pressures. Additionally, the central bank is considering adjusting interest rates in response to these economic shifts.
In this context, you need to assess how the slowing GDP growth is likely to influence the yield of long-term government bonds.
