S.F. is surging to the top of the list of Grade A office property investment yields, according to a Savills/Deakin University World Office Yield Spectrum report released this week. The City by the Bay benefited from an influx of foreign investment in the revived American economy, although uncertainty around an expected interest rate hike led to a broad array of yields among US cities. European office districts, on the other hand, posted a narrower range of results between 3.5% and 4.5% yields.

Hong Kong delivered the lowest effective yield of any city on the list, thanks largely to a thin supply of investment-grade properties. Meanwhile, emerging Asian markets including Vietnam, the Philippines and Indonesia offered some of the continent's best returns. Here is a selection of the findings regarding Grade A office investment yield rates: Hong Kong, 3.11%; Tokyo, 3.95%; Munich, 4.25%; London, 4.38%; Paris, 4.52%; Shanghai, 4.71%; New York, 5.04%; Singapore, 5.29%; LA West, 5.34%; Sydney, 6.52%; San Francisco, 6.97%.
