Expect volatile markets in 2025, economist warns
Sylvain Broyer, chief EMEA economist at S&P Global Ratings, said in a note to clients on Wednesday that investors should brace themselves for a difficult trading environment next year.
"Between the possible correction of the economic anomalies that emerged in 2024 and the potential for policy pivots in 2025, we expect European economies and markets will be subject to high volatility over the coming 12 months," noted Broyer, a member of the European Central Bank's "shadow council" of economists.
The incoming U.S. administration of Donald Trump, changes in EU leadership and forthcoming German elections are all clouding the economic outlook for Europe, he added.

Don’t expect a Bank of England rate cut until February: Morgan Stanley
Investors shouldn't expect interest rates in Britain to go down until 2025, Bruna Skarica, chief U.K. economist at Morgan Stanley, said in a note to clients on Wednesday.
The Bank of England previously hinted that four rate cuts could be on the cards in 2025 — but weak economic data over the past week has dampened hopes that a such a trim is imminent.
Markets are overwhelmingly expecting the Bank of England to hold rates steady at its upcoming Monetary Policy Committee meeting on Thursday, overnight index swap data shows. The data also indicate that traders are divided on whether the central bank will keep its key interest rate at 4.75% or reduce it when the MPC convenes again in February. A small majority is leaning toward a hold.
Skarica said in the Wednesday note that she is positioned away from that consensus, stressing, "We expect the next cut in February."

SBB CEO Leiv Synnes told news agency Reuters on Wednesday that the exchange — which was accepted by 95% of relevant creditors — would allow the firm to press ahead with its restructuring plans.

France has not respected fiscal rules for decades, economist says
Financial markets have allowed countries like France to get away with disrespecting the euro zone's fiscal rules for too long, economist Raphael Gallardo told CNBC Wednesday.
France is among a number of euro zone member states that have failed to meet the single currency union's fiscal rules that require member states to keep budget deficits below 3% of GDP (gross domestic product) and to restrict public debts below 60%.
The French government expects the budget deficit to hit 6.1% of GDP this year, however, while the International Monetary Fund predicts the country's debt to GDP ratio will reach around 112%. Arguments between lawmakers over taxation and spending plans means France currently has no 2025 budget in place and has instead rolled over this year's fiscal plan, as political turbulence continues.
Gallardo, chief economist at Carmignac, said France had not respected the rules for years.
"Unfortunately, the problem in the euro area is that you cannot have a currency union with it without fiscal discipline and a mechanism to enforce that fiscal discipline, and in the case of France, for 25 years, we have never respected the rules," he told CNBC's "Squawk Box Europe" Wednesday.
"The safeguards in the European constitution have been completely unable to enforce it on the French government and the markets haven't done their job either, because they have considered that France — being a core country — will be bailed out," he said.

UK inflation rises to 2.6%
Inflation in the U.K. rose to 2.6% in the year to November, meeting expectations but further dampening hopes of a rate cut from the Bank of England on Thursday.
The U.K.'s annual inflation rate stood at 2.3% in October.
Yields on the U.K.'s 10-year Gilt were little changed by 7:05 a.m. at 4.519%, while the British pound was down 0.07% against the U.S. dollar to trade at around $1.2700.
Markets are now overwhelmingly expecting the Bank of England to hold its key interest rate at 4.75% when its Monetary Policy Committee meets for the final time this year, according to overnight index swap data.

Sterling dips ahead of UK inflation data

Sterling was around 0.1% lower against the euro, and 0.06% weaker against the greenback by 6:35 a.m. London time.
November inflation data, which will be published Wednesday morning, comes after official figures showed wage growth in Britain jumped 5.2% in the three months to October, while the nation's economy unexpectedly contracted that month.
On Thursday, the Bank of England will make its final monetary policy decision of the year.
