August was a month where bond markets traded very nervously and equity markets behaved in the opposite manner, recovering their poise to post strong positive returns after several months of high volatility.
As mentioned in prior reports, a cocktail of strong economic growth, sticky inflation, concerns over government spending and erratic communication from the Federal Reserve had been steadily undermining confidence in the global bond markets for several months. This has largely resulted in bond prices falling and bond yields rising. To add to this list of negative influences, we should also include the effect of rising oil prices and the increasing competition for funds from the AI hyperscalers, who are seeking ever larger amounts from investors to fund their enormous infrastructure rollouts.
The pressure from all these issues resulted in a selloff in the bond markets during August, particularly in longer dated maturities.[1] This, in turn, prompted an important intervention from the US Treasury Secretary, Scott Bessent, who announced the doubling in size of his departments buyback programme for US government bonds.[2] Although small in quantum, the signalling effect was powerful and the bond market took notice. Selling pressure began to dissipate and the upward march in bond yields began to level out.
Towards the end of the month an additional intervention from the US authorities came from Chairman Warsh of the Federal Reserve. His speech at an international meeting of central bankers was widely interpreted as being much more hawkish than previous communications, focussing as it did, on the effort to combat inflation.[3] The combined push from these two important voices had the desired effect, with nervous US bond markets calming somewhat as they factored in a serious effort to deal with inflation and reduce the volatility of market prices.
