With tariff tensions easing a touch for now and price pressures coming off the boil, U.S. Treasury yields have plunged this week - defusing a tense January for bond markets and helping stocks find a foothold in the thick of a noisy earnings season. Although they backed up a touch early Thursday, 10-year Treasury yields have sliced below 4.5% - dropping more than 10 basis points at one point on Wednesday to their lowest of the year as January ISM service sector readings showed a surprise drop in the prices paid by businesses. Along with the prior day's news on some cooling of the labor market and this week's delays in U.S. tariff hikes on Mexico and Canada, the drop in yields came largely independently of futures thinking on Federal Reserve interest rates.
