0515 GMT - Steeper government bond yield curve are likely to be a durable feature of the rates landscape, Goldman Sachs analysts say in a note. "Despite mild spot inflation news, ongoing energy volatility and the AI borrowing boom are keeping G-10 bonds under pressure, especially at the long end of the curve," they say. The analysts anticipate that the inflation and fiscal drivers of higher term premium--additional yield that investors seek to buy a longer-dated bond rather than a shorter-dated one--will prove persistent. "We think high and sticky term premium can coexist with lower rates volatility," they say.
