LONDON, June 30 (Reuters) - The economic pain of higher interest rates seems duller than many had braced for only late last year - and subdued household debt burdens may be at least partly responsible. More interest rate sensitive countries with more flexible loan rates - such at Canada, Australia and Sweden - are already turning higher. What's more, the overall impact of higher borrowing rates is partly offset by rising interest rates on savings. And so net of interest income, JPMorgan points out, interest costs are up only 0.2 percentage point of disposable personal income since the start of the Fed hiking cycle early last year. Higher costs are still coming with a lag for many and will drag on the economies further from here.
