Weak jobs data typically makes traders buy bonds. Here's the mechanic: soft growth lowers the odds the Fed keeps rates high, so future short-term rates are expected to be lower. Bond prices and yields move INVERSELY, so as buyers pile in, prices rise and yields fall. The shorter 2Y note is most 'policy-sensitive' — it hugs where the Fed is headed — so it often moves the most on jobs surprises.

The 'yield curve' just plots yields from short to long maturities. When weak data pushes down rate-hike bets, short yields (2Y) usually drop more than long yields (10Y), so the curve STEEPENS. Beginners watch this because a steepening from the front end (a 'bull steepener') is a classic sign markets expect easier policy ahead, not tighter.

A credit 'spread' is the extra yield investors demand to hold a company's bond over a safe Treasury — pay for taking default risk. Tight spreads (like 78bp) mean investors feel calm about corporate defaults and want the extra income, so they buy credit. If growth fears spiked instead, spreads would WIDEN as investors demand more compensation and prices of riskier bonds fall.

When a central bank buys fewer bonds, it removes a big, price-insensitive buyer — so with less demand, JGB prices tend to fall and yields rise. Higher JGB yields matter globally through the 'carry trade': investors borrow cheaply in yen to buy higher-yielding foreign bonds; if Japanese yields climb, that trade gets less attractive and some money can flow back home, nudging global yields around.

Fewer scheduled meetings means each decision carries more surprise, and bond markets hate surprises: uncertainty raises the 'term premium,' the extra yield investors want for holding longer bonds through unknown events. For a beginner, expect that thinner news windows can produce bigger single-day yield swings when data or Fed comments finally land.

UK gilts don't trade in a vacuum: when US Treasuries rally and yields fall, gilt yields often drift lower too, because the same 'lower-rates' theme flows across borders and global investors arbitrage between safe-haven bonds. Remember the inverse rule — if gilt yields fall, gilt PRICES rise. Longer-dated gilts feel this most because of 'duration': the longer a bond's life, the more its price moves for a given change in yield.

Inflation is a bond's enemy: it erodes the fixed coupons you receive, so rising oil can push gilt yields UP (prices down) even when growth data is soft. Beginners should watch the tug-of-war — weak US jobs pulls yields down, but a sustained oil spike pulls them back up by lifting inflation expectations and the compensation investors demand to lend to the government.
