Treasury yields are moving lower. Yields on the 10-year Treasury note — the key benchmark for mortgages, auto loans and credit card debt — were more than 3 basis points lower at 4.6703%.

The longer-dated 30-year Treasury note yield was also 3 basis points lower at 5.2004%. The yield on the 2-year Treasury note, which typically reacts in line with short-term Federal Reserve interest rate decisions, was 1 basis point lower at 4.2166%.

In a Tuesday morning note, UBS’s Chief Investment Office said they expect bond yields to fall over the long term, which should support “a continued broadening” of the global equity rally.

They advised traders questioning whether to respond to elevated yields to “stay invested.”

“While higher yields are typically a headwind for equities, we believe strong corporate earnings and expectations of further growth should continue to support global equities broadly,” they said. “We now expect S&P 500 earnings per share to grow 25% this year and another 14% next year. In Europe, we see 15% growth in both 2026 and 2027, while we estimate Asia ex-Japan should enjoy earnings growth of 72% this year.”

The Canadian dollar extended its decline against the greenback on Tuesday morning, shedding a further 0.1% to trade at about 0.7212.

The Canadian dollar also fell against the euro and the British pound in early Tuesday trading.

Bitcoin closed in on the $80,000 mark on Tuesday, as renewed inflows into spot bitcoin ETFs and improving risk appetite extended the cryptocurrency’s recent rally.

Long-dated Treasury yields were still relatively high on Monday, but investors can take a few steps to bolster their portfolio for this runup in rates.

Treasury Secretary Scott Bessent has been working to calm higher yields in long-dated Treasurys, announcing last week it would at least double its buyback program. Though yields retreated briefly, they were still elevated on Monday, with the 10-year Treasury yield last at 4.7%. Bond yields and prices move inversely to one another, and price swings related to rate fluctuations are more dramatic for long-dated issues.

The news isn’t all that bad for investors, according to a Monday note from UBS. “Over the longer term, initiatives that result in financial repression and artificially bring down yields should be favorable for equities, while gold would be another beneficiary of this scenario.”

The firm recommended that investors focus on quality bonds with short- to medium-term maturities, “as they are less susceptible to volatility at the long end of the curve.”

Investors should also stay in stocks. “While higher yields are typically a headwind for equities, we believe strong corporate earnings and expectations of further growth should continue to support global equities broadly,” UBS said.

Finally, investors should consider “a mid-single digit allocation” to gold, according to the firm. “As a non-fiat real asset, it can benefit when financial repression fuels fears of currency debasement,” UBS said.
