Remember bond prices and yields move in opposite directions: when investors sell long-dated bonds, prices fall and yields rise. Long bonds have high 'duration', meaning their prices are the most sensitive to yield changes, so a small yield jump causes a large price loss — that is why a deficit/supply scare hits the 30-year hardest. Beginners can read a rising long-end yield as the market demanding more compensation to lend for a long time.

The yield curve plots yields across maturities. The short end (2Y) is pinned by expectations for the Fed's policy rate, while the long end reflects inflation, supply and term premium. When the long end rises faster, the curve 'steepens'. A bear steepener typically signals investors worry about long-run inflation or debt supply rather than imminent rate cuts — useful context for a beginner watching where pressure is concentrated.

This shows the two-way tug on bonds. Geopolitical fear usually sparks a 'flight to safety' that pushes investors into Treasuries — buying bonds lifts their price and pulls yields down. But if the same crisis threatens higher oil and inflation, that argues for higher yields. When yields drift lower after a big sell-off, it can simply be traders taking profit or hedging risk; beginners should watch whether the safe-haven bid or the inflation fear wins out.

A credit spread is the extra yield a company must pay over a same-maturity Treasury to compensate for default risk. A tight 81bp spread means investors are relaxed about corporate defaults. Beginners should note the distinction: rising Treasury yields lift all borrowing costs, but only widening spreads would signal genuine credit stress. Tight spreads alongside a rates sell-off suggest the move is about supply/inflation, not fear of company failures.

Higher oil feeds into inflation, and inflation is a bond's enemy because it erodes the fixed coupons bonds pay. When traders expect more inflation, they demand higher yields, which means lower bond prices. This is why an energy-supply scare can lift yields even when growth fears might normally support bonds — the inflation channel often dominates for fixed-rate lenders.

Inflation data is the biggest driver of government bond yields. A hotter-than-expected UK CPI would make traders bet the Bank of England keeps rates higher for longer, pushing gilt yields up and prices down (the price/yield inverse). Because inflation erodes the fixed coupons gilts pay, higher inflation demands higher yields as compensation. A cooler print would do the opposite. Beginners: watch the surprise versus forecast, not just the headline number.

When 'bond jitters' are mentioned, it means gilt yields are rising and prices falling, often on inflation or global rate spillovers. Higher yields raise government and mortgage borrowing costs, which can weigh on rate-sensitive equity sectors — but energy stocks tend to rise with oil, cushioning the index. For a beginner, this shows how a single shock (Middle East oil risk) can push bond prices down while lifting parts of the stock market at the same time.
