What happened
The US 10-year Treasury yield rose to 5.23%, its highest level since 2007 m.techflowpost.com. It was holding at 5.20% late in the week after peaking at a 19-year high of 5.228% fxstreet.com, a level it had touched earlier in the week as well thinkmarkets.com. The 30-year yield reached a 22-year high fxstreet.comvtmarkets.com and moved above 5.5% moneycontrol.com. Yields edged lower by the end of the week but remained at multi-year highs tradingeconomics.com.
The move was not confined to the United States. Yields on Japan's 10-year bonds rose to their highest level in three decades during a global bond selloff that pushed borrowing rates higher, with US Treasury yields hovering above 5% semafor.com. Trading Economics attributed the pressure on Treasuries to strong economic activity and to concerns over the fiscal outlook tradingeconomics.com.
Why it matters to investors
The repricing is concentrated at the long end of the curve. Friday's moves widened the gaps between short- and long-dated yields, including the two-year to 10-year and five-year segments moneycontrol.com. That is the part of the curve that sets mortgage rates and the discount rate applied to long-duration assets.
The pass-through to housing is already visible. Average 30-year mortgage rates hit 7.03%, the first time they have surpassed 7% since the beginning of last year wsj.com. The effect of rates topping that level is rippling through the market for buyers, sellers and builders wsj.com.
Not every investor reads the level as a warning. CNBC reported that the 19-year high in the 10-year yield has some investors seeing an opportunity to buy bonds, which typically make fixed interest payments for the life of the security cnbc.com.
What to watch
Whether the long end keeps diverging from the front end. VT Markets tied the 30-year move to expectations of further Federal Reserve tightening and pointed to elevated oil prices and rising inflation expectations as reasons to hedge against more yield-curve volatility vtmarkets.com. ThinkMarkets linked the move in the 10-year to expectations that the Federal Reserve and the European Central Bank will act to contain inflationary pressures thinkmarkets.com.
Auction demand is the other gauge. Trading Economics noted the reception at the week's two-year Treasury auction alongside the fiscal concerns weighing on the market tradingeconomics.com. With Japanese yields at three-decade highs semafor.com, the question is whether domestic buyers in Tokyo continue to find local paper more attractive than US paper.
