A More Hawkish Fed Than Expected: Anatomy of a Surprise

In mid-September 2026, the Federal Reserve raised its benchmark rate by an additional 25 basis points, bringing the target range to 3.75–4.00%. This decision, which few observers had anticipated so firmly, rests on a dual observation: on one hand, core PCE inflation refuses to converge toward the 2% target despite 18 months of restrictive policy; on the other, US growth is proving more resilient than expected — second-quarter GDP was revised up to +2.1% annualised.

The strongest signal is not the hike itself but the revised dot plot: sixteen of eighteen FOMC members envision at least one additional hike before end-2026. This potential additional tightening immediately reverberated across bond markets. The 10-year Treasury yield crossed 4.97% in the days following the announcement — a level not seen since the post-COVID hiking cycle of 2023.

For wealth investors, this configuration creates an ambivalent situation: bond yields not seen in nearly twenty years, but simultaneous pressure on risk asset valuations and a strong dollar that erodes returns on unhedged foreign assets.

The 10-Year at 5%: A Rate Regime That Changes the Rules

The symbolic breach of 5% on the US 10-year is not trivial. This threshold marks the return of a significant positive real risk-free rate: with medium-term inflation expectations around 2.3–2.5%, the real yield on the 10-year US sovereign bond is approximately 2.5% — its highest level since 2006.

This context fundamentally redraws the risk premium map. During the 2010–2022 decade, investors were forced to take risk — equities, real estate, high yield credit — to achieve positive real returns. The TINA (« There Is No Alternative ») logic now belongs to the past: short-to-medium US sovereign bonds offer competitive real returns against many risk asset classes.

The US yield curve, long inverted, is beginning a gradual normalisation. The 2–10 year spread has moved from –80bp at the start of 2026 to –25bp today, signalling that recession expectations are fading in favour of a prolonged « higher for longer » scenario.

Valuation Pressure: What the « Fed Model » Tells You

Rising long-term rates exert mechanical pressure on equity valuations through two distinct channels. The first is the discounting effect: a higher risk-free rate increases the cost of capital and compresses valuation multiples, particularly for growth stocks whose cash flows are concentrated in the distant future. With a 10-year at 5%, the Shiller P/E of the S&P 500 at 27x appears clearly stretched — the implied earnings yield (1/27 = 3.7%) is below the risk-free Treasury yield.

The second channel is behavioural: sovereign bonds at 5% attract flows from institutional and wealth investors previously captive to equities by default of alternatives. This slow but steady reallocation can weigh on US equity indices over coming quarters.

Nevertheless, the picture is not uniformly negative for equities. High-dividend « value » stocks — particularly in energy, financials, and industrials — hold up better as their dividend yields (3–5%) remain competitive. European markets, with a Stoxx 600 at a P/E of 13x, offer relatively attractive valuations even in this high-rate environment.

Bond Repositioning: Capturing Yield Without Overextending Duration

In this context, the optimal bond strategy for wealth portfolios rests on three complementary axes.

Favour the 2–5 Year Segment of the US Curve

The short-to-medium portion of the US curve offers the best yield-to-duration ratio. With yields between 4.65% and 4.80%, it captures most of the carry without exposing portfolios to the duration risk of a 10 or 30-year if rates were to rise further. In practice, ETFs such as iShares 1-3Y Treasury Bond (SHY) or iShares 3-7Y Treasury Bond (IEI) represent liquid, low-cost vehicles for this exposure.

Hedge the Dollar Risk

EUR/USD at 1.114 reflects the monetary policy divergence between a hawkish Fed and an ECB in gradual easing mode. For a European investor, the EUR/USD hedge is now inexpensive (compressed interest rate differential) and protects against a potential euro recovery toward 1.15–1.20 if the Fed pivots. EUR-hedged USD bond funds allow you to capture American yields without bearing dollar volatility.

Maintain IG Credit, Avoid US High Yield

EUR Investment Grade credit offers around 3.8% — lower than the US, but without currency risk and with generally more controlled duration. US High Yield, with spreads at just 380bp, offers insufficient compensation for default risk in a high-rate environment with a 2026–2028 refinancing wall looming.
