The macro backdrop

Every theme swims in this tide — judge the week’s moves against it.

📅 On the calendar — and why it matters here

• Fri Sep 25 — FOMC (Fed rate decision / minutes). the single biggest scheduled market mover — a rate surprise in either direction repriced everything, hardest on rate-sensitive names (growth, REITs, utilities, homebuilders). Watch for a surprise vs expectations — that gap, not the number itself, is what moves markets.
• Tue Sep 29 — JOLTS (job openings). labor-market tightness — a cooling read eases wage-inflation fears. Watch for a surprise vs expectations — that gap, not the number itself, is what moves markets.
• Wed Sep 30 — GDP. the broadest growth read — confirms or breaks the soft-landing thesis. Watch for a surprise vs expectations — that gap, not the number itself, is what moves markets.
• Wed Sep 30 — PCE inflation (the Fed's gauge). a hot print pushes rate-cut odds out (pressuring long-duration assets); a soft print does the reverse — one of the highest-impact releases. Watch for a surprise vs expectations — that gap, not the number itself, is what moves markets.
• Fri Oct 2 — Jobs report (payrolls + unemployment). sets the growth-vs-recession narrative — a weak number lifts recession odds (hits cyclicals, consumer, financials); a strong one can paradoxically pressure rates. Watch for a surprise vs expectations — that gap, not the number itself, is what moves markets.

What to watch next

• The 10-year Treasury yield at 5.11% implies a higher cost of capital for critical minerals projects, which are often long-term and capital-intensive. A sustained high yield could make financing new mines or expansions more expensive, potentially slowing development or increasing project costs for companies in this theme. [macro data]
• Expected inflation at 2.33% suggests ongoing price increases, which could affect the operational costs for critical minerals companies, including energy, labor, and equipment. Managing these input costs is a key factor for maintaining profitability in the sector. [macro data]
• The VIX at 15.16 indicates a moderate level of market volatility. While not extremely high, this level suggests that investors may remain cautious, which can influence sentiment and capital flows into riskier sectors like critical minerals, potentially leading to continued stock price fluctuations. [macro data]
• A high-yield credit spread of 2.8% reflects the additional risk premium demanded for lending to companies with lower credit ratings. For critical minerals developers, this spread can impact the cost and availability of debt financing, which is often crucial for funding exploration and development activities. [macro data]
• The Shiller CAPE ratio at 41.25 suggests that the broader market is trading at a historically high valuation. This elevated valuation could imply a greater potential for market corrections, which might affect investor appetite for growth-oriented or riskier sectors like critical minerals, regardless of their individual fundamentals.
