Definitions & data sources
Plotted observation dates
Yields are annual percentages in each country’s own currency. The maturity axis is logarithmic so short-term tenors remain readable alongside long bonds. The yield axis starts at 0%. US Treasury par yields are fitted constant-maturity rates. Canadian bill yields are daily secondary-market money-market yields. Canadian bond yields are closing mid-market yields on selected benchmark bonds, whose actual maturities can differ from the indicated term. Canada's long-term benchmark is shown at the 30-year position for context.
SOFR and CORRA measure overnight borrowing costs secured by government securities. Dashed reference lines show each country’s latest available overnight observation and span all maturities. Only the latest overnight rates are shown.
Offsets such as −1y are measured from the latest curve date. Each country uses its most recent trading observation on or before that target day. A country without observations on that date is labelled unavailable. Lines connect adjacent published maturity points, with gaps for missing tenors. The tooltip snaps to those observations. A positive 10Y minus 2Y spread means the longer-term bond yields more. One basis point is 0.01 percentage points.
