Japan's services sector ground to a halt in May after more than a year of expansion, as surging costs linked to the Middle East war dampened service demand and led to a 12-year high in output price inflation, a private survey showed on Tuesday. • The S&P Global final Japan Services Purchasing Managers' Index (PMI) fell to 50.0 in May from 51.0 in April, marking the end of a 13-month expansion streak. Readings above 50.0 indicate growth in activity, while those below point to a contraction.
