But it is the US where questions are becoming loudest due to the USD’s role as a reserve currency and US Treasuries’ central role as a global benchmark. The US budget deficit (and thus funding requirement) has recently started to widen again in response to tax cuts (and tariff refunds) at a time when the economy is running hot and automatic stabilisers should be lowering the deficit (chart 25).
The increase in the US government’s call on funds comes at a time when hyperscalers and others are massively lifting capex and spending on AI. This is compounding the increase in global spending, which is already being supported by the transition to net zero, defence, and broader security and resilience measures. The lift in global spending generates intense competition for capital and pressure on global savings. The result is that estimates of neutral interest rates are rising, pushing up expected average cash rates, as well as the term premium investors require over and above the expected cash rate to commit capital to long-term bonds.
The inflationary impact of the Iran war and the strength of the US economy have seen markets switch from pricing Fed Fund rate cuts to hikes. Markets now expect the Fed Funds rate to rise to around 4.25% over the next year. But concern the Fed may not actually have the resolve to tighten policy as required, together with the competition for capital, has meant the term premium has not declined as it normally would, keeping the yield curve steeper than would be expected (off the higher cash rate, chart 26).
Fed Chairman Kevin Warsh expressed concern over inflation and the stance of policy at his recent Jackson Hole address, but markets are yet to be convinced the Fed has the resolve to tighten and lower inflation.
Central bank credibility is essential to anchor inflation expectations and bond yields. The market is approaching a crucial point and strongly signalling that the Fed needs to lift rates. Failure to so could cause yields to spike significantly. But we do anticipate the Fed will shift in this direction and conditions should start to normalise somewhat.
