title: "Reading a CDS spread" description: "What 198 basis points actually tells you. How to translate a CDS quote into default probability, and why the cross-asset signal matters." sectionLabel: "Credit Signals" order: 1

A credit default swap is a contract between two parties. The buyer pays an annual premium to the seller. In exchange, if the reference company defaults, the seller pays the buyer the difference between the bond's face value and its post-default recovery value.

The annual premium, quoted in basis points of notional, is the CDS spread. When you read "Oracle 5-year CDS at 198 basis points," that means: insuring $10 million of Oracle bonds against default for five years costs $198,000 per year.

The number is small in absolute terms. The information it carries is large.

From spread to default probability

The CDS spread implies a market-priced default probability. The simplified relationship:

Annual default probability ≈ Spread / (1 - Recovery Rate)

For senior unsecured corporate bonds, the standard recovery assumption is 40%. So:

At 60 basis points (Oracle's baseline): 60 / (1 - 0.40) = 100bps = 1.0% annualized default probability.

At 198 basis points (Oracle today): 198 / 0.60 = 330bps = 3.3% annualized default probability.

That is a triple. The market is now pricing Oracle as roughly three times more likely to default in any given year than it was three years ago. Cumulatively over five years, the change is even larger because default probabilities compound.

This is not a forecast. It is a market-implied number. Real-world default rates for investment-grade names are much lower than CDS-implied rates. The CDS market embeds a "risk premium": investors demand compensation above expected loss to bear the risk. But that risk premium is itself informative. When it rises, the market is demanding more compensation to hold the credit.

What moves a CDS spread

Three things drive CDS spread changes:

Balance sheet deterioration. Earnings miss, debt issuance, capex commitment, deteriorating cash flow. These show up first in CDS because the CDS market has direct exposure to the recovery value if things go wrong.

Volatility of firm value. From the Merton model, equity is a call option on firm assets. The credit spread is the put premium on the same assets. When equity volatility rises, the put gets more valuable, even if the firm's leverage has not changed.

Liquidity and technicals. CDS markets are dealer-intermediated and thinner than equity markets. Single-name CDS can move on flow alone (dealer hedging, index rebalancing, structured product unwinds). The signal is noisier on short timeframes.

Why CDS leads bonds, which lead equity

There is a documented information hierarchy in corporate credit:

1. CDS market moves first. Hedge funds and credit-focused investors trade single-name CDS continuously. The market is liquid enough to express views quickly.
2. Cash bond market follows. Bond traders watch CDS to inform mark-to-market and to hedge inventory.
3. Equity options follow next. As CDS widens, implied volatility on the equity rises.
4. Equity itself moves last. Equity research desks are typically running on a quarterly earnings cycle. They are slow to incorporate credit signals.

This is why a sophisticated equity investor watches CDS. It is the leading edge of information about balance sheet stress, and it leads equity by weeks or months.

How to use this in practice

A practical workflow:

Define a baseline. What is the name's CDS spread in a normal environment? For Oracle, that was 60bps for years. For Microsoft, it has been around 25bps. The baseline is what "calm" looks like for that specific name.

Define watch and alarm thresholds. Watch is where you start paying attention. Alarm is where you start acting. In the Credit Monitor, Oracle's watch threshold is 150bps and alarm is 250bps. The 100bps gap reflects the noise in single-name CDS.

Watch the cross-asset confirmation. A single-name CDS move can be a head-fake. Look for: BBB OAS widening (sector-wide), HY OAS widening (risk-off), HYG/IEF or LQD/IEF ratios falling (relative underperformance), VIX or MOVE rising (cross-asset vol). When two or more of these confirm, the signal is real.

Translate to portfolio action. If you hold the equity, the playbook is hedge (puts, reduced position size) or rotate (out of the highest-leverage names). If you do not hold the equity, the signal is informational: it tells you what the smart money in credit thinks is happening.

Why this matters for the weekly dashboard

Every Monday and Friday, the Public Equities Ledger publishes the Credit Monitor with current spreads for the five hyperscalers (ORCL, META, MSFT, GOOGL, AMZN) plus broad credit indices (BBB OAS, HY OAS) and cross-asset vol (VIX, MOVE).

The point is not the individual numbers. It is the pattern. When the same direction shows up in multiple indicators, the regime is changing. That is when this publication is most useful.
