Understanding the regime change
Why are central banks buying so much gold?
Gold is often described as a hedge against inflation, geopolitical tension or a weaker dollar. That interpretation remains valid, but it no longer fully explains the scale of central-bank purchases.
01A revealing divergence
While some Western investors periodically reduce their exposure to gold, central banks are increasing their reserves. They do not operate on a quarterly horizon or under the same performance constraints: their priority is to preserve the value and liquidity of their reserves over several decades.
02Risk is shifting towards sovereign bonds
For nearly forty years, government debt was regarded as the risk-free asset par excellence. Yet a bond can be repaid at maturity and still generate a substantial loss when interest rates rise. The longer its maturity, the more sensitive its value is to that rise.
The increase in long-term yields reflects a new requirement: investors are demanding higher returns to finance increasingly indebted governments.
03Debt, interest rates and money creation
Large deficits require more bond issuance. This additional supply can weigh on bond prices, push yields higher and increase governments’ interest burden. Financing that burden then feeds further deficits.
At the same time, the financial system remains dependent on abundant liquidity. Markets require scarcer money to protect the value of bonds, while the economy needs more abundant money to absorb the debt. This contradiction defines the current regime change.
“Gold does not depend on the solvency of any government and never needs to be refinanced.”
04What central banks are looking for
Gold pays no coupon, but it is nobody’s liability. Long considered a weakness, that characteristic becomes an advantage again when the value of sovereign bonds is called into question. Gold purchases can therefore be understood as diversification away from interest-rate risk, fiscal risk and dependence on a reserve currency.
05The key takeaway
The question is no longer simply whether gold protects against inflation. It is what happens when the asset regarded as the safest in the financial system itself becomes a source of risk. In that environment, gold returns to its historic role: a reserve asset that relies on no promise of repayment.
