Treasury yields edged higher Tuesday as voting began in the U.S. midterm elections, while investors parse a busy week of economic data and renewed Middle East tensions that pushed oil prices higher.

Yields on 10-year U.S. Treasurys — the main benchmark for mortgages, auto loans and credit card debt — rose more than 2 basis points to 4.9167%.

The yield on longer-dated 30-year U.S. Treasurys — which tends to move more on geopolitical developments — was up 1 basis point at 5.2879%.

The yield on the 2-year Treasury note, which more closely follows short-term Federal Reserve rate decisions, was up more than 1 basis point at 4.5956%.

One basis point equals 0.01%, or 1/100th of 1%, and yields and prices move inversely to one another.

The moves follow a mixed day for Treasurys on Monday, with the benchmark 10-year yield moving 2 basis points lower, and the shorter-dated 2-year note yield rose by more than 1 basis point.

With Americans voting in the midterm elections Tuesday, investors are keeping a close eye on how the result will shape Congress and move markets.
