Robin J Brooks predicted the European Central Bank would intervene if French government debt came under heavier pressure, outlining possible tools that could affect euro area borrowing costs without representing announced policy.
In an Oct. 25 post, Brooks pointed to France’s 10-year real yield, which he said had moved above the comparable U.S. yield. He argued that rising inflation-adjusted borrowing costs matter even as bond spreads remain tight enough to complicate use of the ECB’s Transmission Protection Instrument (TPI).
Brooks said the ECB could create a new support facility if doubts prevented use of the TPI. The instrument’s published terms do not specify a fixed spread threshold and call for assessments of market conditions, monetary-policy transmission, eligibility and proportionality, as described in earlier EconoTimes coverage of the TPI. Brooks also suggested the ECB could define a new tool around real yields rather than spreads.
Other steps in his scenario involve the central bank’s balance sheet. Brooks said the ECB could adjust how much of the proceeds from maturing French bonds it reinvests and could later halt quantitative tightening altogether. He said the reinvestment would help limit upward pressure on yields.
Brooks noted that ECB runoff of French debt appeared unusually low in September compared with the amount of French debt maturing that month. He cautioned that the difference could reflect the ECB’s holdings of particular maturities or noise in the data.
As precedent, Brooks pointed to Mario Draghi’s 2012 “whatever it takes” speech and the TPI’s introduction in 2022. Brooks said details of ECB actions to limit Italian and Spanish yields in 2022 emerged years later. His scenario depends on whether selling pressure on French debt escalates and yield pressure persists; he cited no scheduled decision on the measures he discussed.
