Sovereign fiscal paths in the G7 are increasingly the dominant driver of long-end yields.
We outline the framework we use to size duration exposure across mandates.
Debt levels alone do not determine sustainability. Currency denomination, maturity, domestic savings and institutional credibility all affect the market's willingness to finance a government at a stable cost.
“When fiscal policy drives the long end, duration must be priced as a risk position rather than a passive hedge.”
- 01Large refinancing needs can increase sensitivity at the long end of the curve.
- 02Inflation credibility and debt maturity profiles differ sharply by country.
- 03Duration exposure should reflect both valuation and its intended portfolio role.
The interaction between fiscal spending and monetary policy is particularly important. A central bank can influence short rates, but persistent issuance may still demand a higher term premium from long-term investors.
Across mandates, we separate duration held for income from duration intended as protection. Those positions may behave differently when inflation, growth and supply shocks arrive together.
A disciplined framework sets the role of each position before it is added and reviews that role as market pricing changes.
