Citable research brief

Core conclusion · Tlines extraction

SMBC's US Rates Strategy report discusses the limitations of AI-based inflation forecasts, favors steepening the 5s30s curve, and expects modest improvements in inflation and labor data to keep the Fed on hold. The report also highlights opportunities in swap spreads and anticipates the upcoming FOMC minutes and industrial production data.

Key arguments

AI inflation forecasts show lower MSE than economists but exhibit data leakage, making them less accurate in true out-of-sample tests.
The Fed's pause in reserve management purchases is not a signal of longer-term balance sheet plans; reserves remain steady at ~$3trn.
Favor 5s30s steepeners due to easing inflation and softer labor data, with long-end yields vulnerable to fiscal and AI capex supply risks.
Lower expected volatility and robust risk sentiment favor swap spreads in the short term.
July inflation data were a step in the right direction, but hawkish Fed speak warrants a 'show-me' attitude.
Industrial production is forecast to rise 0.3% m/m in July.
FOMC minutes may reveal details on how patient members are willing to be regarding inflation.
The 30y swap spreads have room to catch up as 5y and 10y are near highs.

Main risks

Geopolitical risks and lack of clarity on Fed's reaction function could trigger higher yields.
Hawkish Fed stance or change in issuance mix could threaten steepeners.
AI forecast accuracy may be overstated due to data leakage in training.
Supply from AI capex cycle and fiscal concerns could weigh on long-end.

Corresponding source evidence

The Fed temporarily paused its reserve management purchases. We do not believe this is an indication of its longer-term balance sheet plans. Bank reserves have held steady around $3trn since June and softer overnight funding rates largely reflect reduced demand for financing rather than an oversupply of liquidity. · short_term
Favor 5s30s steepeners as easing inflation and softer labor data support belly, while long-end yields remain vulnerable to fiscal and AI capex led supply risks. · medium_term
Lower expected volatility and a robust risk sentiment favors swap spreads as carry should be helped in the short term. · short_term

Conditions / invalidation

If more disinflationary evidence emerges, markets may fully price out hikes.
If the Treasury changes issuance mix, steepeners could suffer.
