Global PMI Indices (diffusion indices)
(y-axis – PMI suppliers’ delivery times (reversed); x-axis – PMI new export orders, change between February 2021 and Q2 2020)

Notes: The size of the bubbles is proportional to the change in the PMI index for input prices between February 2021 and Q2 2020. Grey dots reflect increases in the PMI index for input prices below 10, yellow dots reflect increases between 10 and 15 and blue dots reflect increases in the PMI index greater than 15.
Rising ocean freight shipping costs are another sign of supply bottlenecks (Chart C, upper panel). Since the second half of 2020, global freight shipping costs have been on a steady recovery path from the lows reached in the midst of the pandemic. In recent months, however, they have reached levels not seen since after the Great Financial Crisis, while growth rates have risen above those observed since 2015. At the same time, transport costs on shipping routes from Asia and China to Europe and the Mediterranean, as well as the United States, have experienced a particularly sharp rise since the second half of the year. They appear to have peaked recently (Chart C, lower panel). Two factors are associated with the increase in shipping costs. On the one hand, the strong rise in demand for intermediate inputs on the back of stronger manufacturing activity raised the demand for Chinese exports and the demand for container shipments. At the same time, shortages of containers at Asian ports have exacerbated supply bottlenecks and further increased shipping costs as companies in Asia are reported to be paying premium rates to get containers back.
