Low spreads may incentivize investors to seek higher yields in riskier assets, potentially leading to increased volatility in the bond market. According to a recent report by S&P Global, the investment-grade corporate default rate is expected to remain below 2% in 2026, reflecting a healthier corporate landscape. As central banks continue to navigate the balance between inflation and economic growth, the investment-grade bond market will likely remain a focal point for investors seeking stability amid uncertainty. The strategies employed by corporations to maintain strong balance sheets will play a crucial role in shaping future bond performance.
