We offer evidence that interest rate spreads on syndicated loans to corporate borrowers are economically significantly smaller in Europe than in the U.S., other things equal. Differences in borrower, loan and lender characteristics associated with equilibrium mechanisms suggested in the literature do not appear to explain the phenomenon. Borrowers overwhelmingly issue in their natural home market and bank portfolios display significant home "bias." This may explain why pricing discrepancies are not competed away, but the fundamental causes of the discrepancies remain a puzzle. Thus, important determinants of loan origination market outcomes remain to be identified, home "bias" appears to be material for pricing, and corporate financing costs differ in Europe and the U.S.
