After years dominated by the pandemic, supply chains, energy and inflation, there was a new topic topping the agenda at the World Bank and International Monetary Fund’s Spring Meetings this year: tariffs.

The IMF set the tone by kicking off the week with the release of its latest economic forecasts, which cut growth outlooks for the U.S., U.K. and many Asian countries. While economists, central bankers and politicians have been engaged in panels and behind-the-scenes talks, many are attempting to work out whether trade tensions between China and the U.S. are — or perhaps are not — cooling.

Policymakers from the European Central Bank that CNBC spoke to this week broadly stuck a dovish-leaning tone, indicating they saw interest rates continuing to fall and few upside risks to euro zone inflation. However, all stressed the current high levels of uncertainty, the need to keep monitoring data, and the high risks to the growth outlook — sentiments also echoed by Bank of England Governor Andrew Bailey in his interview with CNBC on Thursday.

These were some of the main messages from ECB members this week.

“The net impact on inflation will depend on what countermeasures are eventually taken by Europe. Then we have to take into account the [German] fiscal push by the defense investments, by the infrastructure fund.”

“We have seen successive movements, you know, announcement [of U.S. tariffs], and then a pause, and then some exemptions. So we have to be very attentive… Either we cut, either we pause, but we will be data dependent to the extreme.”

On market moves:

“When we had done our projections, we anticipated that… the dollar would appreciate, the euro would depreciate. It’s not what we saw. And there have been some counter-intuitive movements in various categories.”

“The German market has obviously been shocked in a positive way by the program soon to be put in place by the German government, with a commitment to defense, with a commitment to a big fund for infrastructure development.”

President Donald Trump denied that an aggressive bond market sell-off influenced his decision earlier this month to hold off on aggressive “reciprocal” tariffs against U.S. trading partners.

“I wasn’t worried,” Trump said in a Time magazine interview during which he was asked about financial market tumult after his April 2 “liberation day” announcement.

In the decree, Trump slapped 10% across-the-board duties against all U.S. imports and released list of tariffs against dozens of other nations. The extra levies were based on trade deficits the U.S. had against the respective countries and raised fears about inflation, a potential recession and disruption of long-held trade agreements.

Markets recoiled following the release. Treasury yields initially headed lower but quickly snapped higher. The 10-year yield rose half a percentage point in just a few days, one of its quickest moves ever, as investors also ditched stocks and the U.S. dollar.

Ultimately, Trump issued a 90-day stay on the reciprocal tariffs to allow time for negotiation. But he said it wasn’t because of the market tumult.

“No, it wasn’t for that reason,” Trump told Time in the interview from Tuesday that was published Friday. “I’m doing that until we come up with the numbers that I want to come up with. I’ve met with a lot of countries. I’ve talked on the telephone. I don’t even want them to come in.”

Yields have since moved lower, with the 10-year most recently around 4.28%, about a quarter percentage point higher than its recent low. Trump had said when he made the decision to hold off that the bond market had gotten the “yips.”

“The bond market was getting the yips, but I wasn’t. Because I know what we have,” he said. “I know what we have, but I also know we won’t have it for long if we allowed four more years of the gross incompetence. This thing was just running — it was running as a free spirit. This was — this was the most incompetent president in history.”

Though negotiations over tariffs are ongoing, Trump added that he would consider it a “total victory” even if the U.S. has levies as high as 50% still in place a year from now.

The Bank of England is focused on the potential impact of U.S. tariffs on U.K. economic growth if there is a slowdown in global trade, the central bank’s governor Andrew Bailey said Thursday.

“We’re certainly quite focused on the growth shock,” Bailey told CNBC’s Sara Eisen in an interview at the IMF-World Bank Spring Meetings.

Going into its May 8 monetary policy meeting, the central bank will consider “arguments on both sides” around the impact of tariffs on growth and domestic supply constraints on inflation, Bailey said.

“There is clearly a growth issue we start with, with weak growth … but a big question mark is how much of that is caused by the weak demand, how much of it is caused by a weak supply side,” he continued.

“Because the weak supply side, of course, unfortunately, has the sort of the upside effect on inflation. So we’ve got to balance those two. But I think the trade issue is now the new part of that story.”

Inflation could be pulled in either direction by wider forces, with a redirection of trade exports into other markets being disinflationary, but a retaliation on U.S. tariffs by the U.K. government — which he stressed did not appear likely — pushing up inflation.

Bailey added that he did not see the U.K. as being close to a recession at present, but that it was clear economic uncertainty was weighing on business and consumer confidence.

The IMF earlier this week downgraded its 2025 growth forecast for the U.K. to 1.1% from 1.6%, citing the impact of U.S. President Donald Trump’s trade tariffs, higher borrowing costs and increased energy prices.

However, economic forecasting remains mired in uncertainty as countries engage in negotiations with U.S. officials over Trump’s swingeing universal tariff policy, currently on pause. The U.S. has imposed 25% tariffs on steel, aluminum and autos and a 10% levy on other British exports.

U.K. policymakers have expressed hopes of reaching a trade deal with the White House, with U.S. Vice President J. D. Vance saying there is a “good chance” of an agreement.

Bailey told CNBC on Thursday that he would be “very encouraged if the U.K. does make a deal,” but that its economy was very open and services-oriented, so it would still be impacted by a wider slowdown in growth or trade.

He also noted that inflation would increase from the current 2.6% in the coming readings due to effects from markets such as energy prices and water bills, but that the bump up would be “nothing like what we saw a few years ago.”

The Bank of England held interest rates at 4.5% at its March meeting, before Trump shocked the world with the scale of his tariff announcement.

Markets now see the BOE slashing rates to 4% by its August meeting.
