Remember the see-saw: when bond prices fall, their yields rise. Traders have been selling long-dated bonds (pushing 30Y/10Y yields up) because they fear heavy future government borrowing will flood the market with new bonds. Long bonds have high 'duration', meaning their prices swing hardest when yields move, so that is where the damage concentrates. When the long end rises faster than the short end, the curve 'steepens' — a classic sign investors are demanding extra reward to lend for longer.

A debt buyback is when the Treasury repurchases some older bonds to smooth out supply and support prices. Beginners should note the two-way reaction: buybacks can gently push targeted bond prices up (yields down), but if investors read them as a sign of deeper trouble, they may demand higher yields on new debt instead. When a big investor flags a 'debt crisis' risk, money often rotates toward hard assets like gold — which is exactly why bullion has been rebounding.

A credit spread is the extra yield companies pay over safe government bonds to compensate for default risk. When spreads stay tight (small) even as Treasury yields jump, it tells beginners the market sees the problem as a 'rates/supply' story, not a 'companies are in trouble' story. If fear about the economy grew, you would expect spreads to widen as investors demanded more cushion for holding corporate bonds.

Bonds from different countries don't always move together. When global yields rise but Chinese yields stay put, Chinese bond prices hold up better, so some investors add them to spread risk. For a beginner, this is diversification in action: holding bonds that behave differently can steady a portfolio when one market sells off.

Gilts are UK government bonds and they rarely move in isolation. When US Treasury and other global long-yields climb, UK gilt prices usually fall in sympathy (so gilt yields rise), because investors compare yields across countries — if bonds elsewhere pay more, UK debt must offer more too. Longer-dated gilts, with their higher duration, would feel the biggest price swings, and higher gilt yields feed directly into UK mortgage and government borrowing costs.
