Summary: US GDP up 1.7% (6.9% annualised) in December quarter, more than 1.4% expected; inventory main driver of result; GDP price deflator annual rate rises from 5.5% to 6.4%.
US GDP growth slowed in the second quarter of 2019 before stabilising at about 0.5% per quarter. At the same time, US bond yields suggested future growth rates would be below trend. The US Fed agreed and it reduced its federal funds range three times in the second half of 2019. Pandemic restrictions in the June quarter of 2020 sent parts of the US economy into hibernation; the lifting of those same restrictions sparked a rapid recovery.
The US Bureau of Economic Analysis has now released December quarter “advance” GDP estimates and they indicate the US economy expanded by 1.7% or at an annualised growth rate of 6.9%. The figure was higher than the +1.4% (+5.7% annualised) which had been generally expected as well as the September quarter’s 0.6% expansion after revisions.
“A large driver of growth was a lift in inventories, which contributed 4.9% to quarterly growth,” said ANZ economist Kishti Sen. “Net exports of goods and services were flat in the quarter. Government spending subtracted 0.5%.”
US GDP numbers are published in a manner which is different to most other countries; quarterly figures are compounded to give an annualised figure. In countries such as Australia and the UK, an annual figure is calculated by taking the latest number and comparing it with the figure from the same period in the previous year. The diagram above shows US GDP once it has been expressed in the normal manner, as well as the annualised figure.
US Treasury bond yields moved higher at the short end but noticeably lower at the long end on the day. By the end of it, the 2-year Treasury bond yield had added 3bps to 1.19% while the 10-year yield had lost 7bps to 1.81% and the 30-year yield had shed 9bps to 2.09%.
In terms of US Fed policy, expectations of any change in the federal funds rate over the next 12 months firmed slightly in favour of earlier rate rises. Federal funds futures contracts for March implied an effective federal funds rate of 0.23%, 15bps above the current spot rate, while April contracts implied an effective federal funds rate of 0.385% and June contracts implied 0.67%. February 2023 futures contracts implied an effective federal funds rate of 1.345%, 127bps above the spot rate.
One part of the report which is often overlooked are the figures regarding the GDP price deflator, which is another measure of inflation. The GDP price deflator is restricted to new, domestically-produced goods and services and it is not based on a fixed basket as is the case for the consumer price index (CPI). The annual rate rose from the September quarter’s revised figure of 5.5% to 6.4%.
