Remember the core rule: bond prices and yields move in opposite directions, so rising yields mean prices are falling. Traders demand higher yields to hold long bonds when they worry about heavy government borrowing and inflation. Long bonds have high 'duration,' meaning their prices are very sensitive to yield moves — that is why the 30Y moves more dramatically than the 2Y, and why beginners see the biggest swings at the long end.

A buyback is when the Treasury repurchases existing bonds, which reduces supply and can gently push prices up and yields down. Beginners should note the lesson here: markets move on expectations, so even a small buyback can rally bonds if traders read it as a sign officials will step in to calm the long end. The reaction depends on what the action implies about future policy, not just the headline number.

A credit spread is the reward for taking on corporate default risk versus 'risk-free' Treasuries. Tight spreads like 81 bp signal calm and confidence about companies repaying. Beginners should watch whether spreads widen: that would mean investors are getting nervous about credit, and corporate bond prices would fall even faster than Treasuries. For now, tight spreads say the stress is about rates and government debt, not company health.

When one bond market moves opposite to others, it becomes valuable for diversification — its price does not fall at the same time as everyone else's. Low, stable Chinese yields reflect a very different policy and inflation backdrop. Beginners can see this as a live example of how not all government bonds move together, which is why investors spread money across countries to smooth out returns.

Global bond markets move together, so when US long yields rise, UK gilt yields usually follow and gilt prices fall — the same price/yield inverse applies. Long-dated gilts carry high duration, so a global yield move hits their prices hardest. Beginners should note that a UK bond can sell off even with no domestic news, simply because international investors reprice all government debt at once.

Regulatory approvals like this rarely shift gilt prices, but they matter for a bank's funding and expansion, which can feed into its own bond spreads over gilts. Beginners can treat gilts as the UK 'risk-free' benchmark: a bank's bonds trade at a spread above gilts, and healthier, better-regulated banks tend to command tighter spreads — a smaller yield premium over the government curve.
