What happened

The Federal Reserve increased interest rates for the first time in three years. The decision was unanimous, but there is uncertainty about future rate hikes.

Why it mattersInterest rate changes affect borrowing costs and investment decisions, influencing economic growth and market stability.

Market context The Fed's unanimous decision to raise rates marks a shift in monetary policy, with mixed signals about future rate paths, creating market uncertainty.

Already priced in? The rate hike was anticipated, but the market is uncertain about the pace of future increases.

How it spreads

Each step below is caused by the step above it. The first effect is obvious and already reflected in prices. The ones after it usually are not.

1 The cost of money strong

Moves government bond yields, which set the baseline return every other investment is judged against. When that baseline moves, everything reprices.

  1. Government bond yields rise as the cost of borrowing increases. The Fed's rate hike leads to higher Treasury yields, reflecting increased baseline borrowing costs.
  2. Higher yields make equities less attractive compared to bonds. As bond yields rise, the relative attractiveness of equities declines due to higher discount rates applied to future earnings.

2 Borrowing costs moderate

Changes how expensive or how easy it is for companies to borrow, which matters most for those already carrying a lot of debt.

  1. Companies face higher borrowing costs. The rate hike increases interest expenses for firms with variable-rate debt and those seeking new financing.
  2. Higher costs may reduce corporate profits. Increased interest expenses can squeeze profit margins, particularly for highly leveraged companies.

3 Who is forced to trade speculative

Interacts with bets investors already hold. When a crowded position goes wrong, forced selling pushes the move further than the news alone justifies.

  1. Investors adjust portfolios to reduce risk. The rate hike prompts portfolio rebalancing, with investors reducing exposure to rate-sensitive assets.
  2. This leads to increased market volatility. Portfolio adjustments in response to rate changes can lead to significant asset price fluctuations.

What it means for each market

Government bonds
US 10-year Treasury yield 10 to 20 basis points

US Treasury yields are likely to rise as investors adjust to higher interest rates.

Mechanism The Fed's rate hike increases the expected path of future short-term rates, pushing up yields on longer-term Treasuries.

Direct effect days
Shares
S&P 500 1% to 2%

Equity markets may decline as higher yields make stocks less attractive.

Mechanism As discount rates rise, the present value of future corporate earnings decreases, leading to lower equity valuations.

Knock-on effect weeks
Corporate debt
US corporate bonds 5 to 10 basis points

Corporate bond spreads could widen as borrowing costs increase.

Mechanism Higher interest rates raise the cost of capital for companies, potentially increasing credit risk and widening spreads.

What the market may be missing

Investors may not fully appreciate the impact of sustained rate hikes on consumer spending and economic growth.

The cumulative effect of multiple rate hikes could significantly dampen consumer demand, slowing economic momentum more than currently anticipated.

How you would act on it
Buy US Treasury yields

Consider buying US Treasury bonds to benefit from rising yields.

Long US Treasury futures
How it loses money: Yields could fall if economic data weakens, leading to bond price increases.

What would prove this wrong

  • If inflation data shows a significant decline, reducing the need for further rate hikes.
  • If consumer spending remains robust despite higher borrowing costs.
  • If corporate earnings continue to grow, offsetting higher interest expenses.
What to watch next
  • Upcoming US inflation reports
  • Fed's next policy meeting
  • Economic growth data releases
