How Government Bonds Behave During Economic Downturns
When recession risks rise, government bonds tend to stand out for their distinctive defensive qualities within diversified portfolios. Not only have they demonstrated the ability to help preserve capital relative to riskier assets during economic downturns, they also have the potential to deliver positive total returns, particularly when the monetary policy backdrop is supportive.
Backed by high credit quality and dependable income
For defensive positioning, high quality government bonds are among the more secure assets available. They are issued by sovereign governments with strong creditworthiness, as debt defaults by developed market governments are extremely rare. For investors who hold these bonds to maturity, the investment has low credit risk, and for this reason, government bonds have long served as a core anchor allocation in balanced portfolios.
Another important defensive characteristic is their relatively predictable income stream. Government bonds pay fixed coupons (typically semi-annually) which continue uninterrupted through economic downturns. Unlike equity dividends, which often fall when corporate earnings decline, government bond coupons provide steady cash flow. This supports portfolio stability and enables more efficient financial planning.
More resilient and less correlated to equities than corporate bonds
During recessions, rotating out of equities into corporate bonds rather than government bonds has historically tended to be a less effective defensive strategy.
- Higher-quality investment grade corporate bonds trade closely with government bonds. However, sector-specific risks can diverge significantly during a downturn, with those most exposed to a recession more likely to suffer credit downgrades and heightened volatility as credit spreads widen.
- Riskier high yield bonds may offer relatively higher coupons and shorter maturity profiles, but this is outweighed by the increased risk of default among more indebted issuers. In practice, high yield bonds tend to behave more like risk assets during recessions.
Government bonds, by contrast, have historically maintained lower correlation with risk assets. This is why many investors reallocate from equities into government bonds at initial signs of recession to help mitigate the impact of large equity market drawdowns.
During meaningful equity drawdowns, bonds delivered positive returns and diversified to a greater degree during recessions

Drawdowns were classified as any drop larger than 12% relative to the previous peak. There were two drawdowns recorded during the 1973 recession. Monthly data was used as proxy for Treasury return and return was calculated based on the monthly peak to trough dates of drawdowns. We referred to the month end date immediately following the start of the market drawdown.
Compensating for losses elsewhere in the portfolio
Beyond their safe-haven attributes, government bonds also have historically had the potential to generate capital gains during recessions, helping to offset losses in riskier segments of portfolios.
Interest rates: During recessions, central banks typically respond by cutting interest rates to stimulate economic growth. This can push government bond yields lower and prices higher, particularly for longer-dated maturities as they hold higher duration. For example, during the 2008 global financial crisis, rapid and coordinated interest rate cuts across major economies led long-dated Treasury bonds to rally by approximately one-third over the calendar year. These returns helped cushion portfolios against severe drawdowns in equity and credit markets.
Quantitative easing: Central banks may also deploy unconventional policy tools to mitigate the impact of a recession. The most well-known is quantitative easing (QE), whereby central banks purchase large quantities of government bonds. By pushing yields lower, QE can help support total returns for bond investors while also reducing government financing costs, creating additional scope for economic stimulus.
When used in moderation, QE may help to stabilise bond yields and support market liquidity. When used extensively or for prolonged periods, however, it may increase the correlation between government bonds and risk assets, potentially weakening the traditional defensive behaviour of sovereign debt.
The benefits of liquidity
Government bond markets are among the deepest and most liquid in the world, allowing investors to trade efficiently and at scale. Because these markets are deep and active, prices adjust quickly, helping to limit overall volatility.
High levels of liquidity can also support the broader economy in the aftermath of a recession. Investors are able to quickly redeploy capital from sovereign bonds into riskier assets as conditions improve. For more active or opportunistic investors, government bond holdings can also serve as a flexible reserve of capital or ‘dry powder’, enabling them to respond to market dislocations.
Bottom line
Government bonds remain an important component of diversified portfolios during recessions because they combine strong sovereign credit quality, historically reliable income through contractual coupons, and the potential for capital gains when interest rates fall. They may help cushion portfolios during economic downturns while providing flexibility to reposition portfolios for the recovery that follows.
