🚨 New KITE analysis on the EU–India trade deal: Simulations show sizable trade effects from the “mother of all deals” linking ~1/4 of global GDP and ~1/5 of the world’s population. Beyond gains, it strengthens supply-chain diversification and market access in an uncertain global economy. Link here👇

Teures Eigentor: US-Strafzölle treffen vor allem die eigene Wirtschaft: 96 % der Kosten tragen Importeure & Verbraucher in den USA, nicht ausländische Exporteure, wie neue Forschung von @julianhi.nz, @aaron-lohmann.bsky.social, @hendrikmahlkow.com & Anna Vorwig zeigt 👇

US consumers bore 96% of the cost of the 2025 Trump tariffs. Impeccable timing for this paper by @julianhi.nz and colleagues at @kiel.institute. www.kielinstitut.de/de/publikati...

Mindestimportpreise für chinesische E-Autos sind die schlechteste Lösung, kommentiert @julianhi.nz, sie zementieren Überkapazitäten, schaffen ein Bürokratie- und Lobbying-Monster und die EU verschenkt mit einer solchen Maßnahme massive Einnahmen 👇

Ein „Deal“ im #Handelsstreit 🇺🇸🇨🇳 könnte Zollpausen & Ausnahmen bei Exportkontrollen bringen, sagt @julianhi.nz #tagesthemen. Beide Seiten können gewinnen & verlieren, Zollniveau bleibt höher als vor Trump. Größtes Plus für 🇪🇺: weniger Unsicherheit 👇

Simulations with the KITE Model show a joint response would raise US costs by 34% vs. no retaliation—reaching ~60% of the effect of a global reaction. In contrast, going it alone is less effective and riskier, esp. for integrated economies like 🇨🇦 & 🇲🇽 👇 @emanuelornelas.bsky.social @ckhead.bsky.social

There is talk of an EU-US trade deal. The EU shouldn't agree to a WTO rule-breaking shakedown that undermines the multilateral system. Instead, it should build a coalition to push back.👇 NB: The piece is written by a coalition of coauthors from Canada, Brazil, France and Germany.

🚨 KITE Insta-Analys: Trump just suggested additional 50% tariff on all goods imports from EU. This one would hurt the EU: 🇩🇪 Germany real output falls –0.78%, 🇪🇺 EU27 –0.66%, 🇺🇸 US -1.51%. In EU hardest hit sector is transportation (automotive, aircraft, etc.): -5% real production. 1/n

🚨 KITE Insta-Analys: US-China 90-day tariff pause provides short-term relief. US real GDP impact improves from -1.6% to -1.29%, and inflation eases to +4.3%. 🇨🇳 China’s real GDP loss shrinks to -0.5%. 🇩🇪 Germany and 🇪🇺 EU hardly move compared to previous situation (-0.22% and -0.14%). 1/n

🚨 KITE Insta-Analysis Update: Additional +34% tariffs by 🇨🇳 China on imports from 🇺🇸 USA, and in response an additional +50% tariffs vice versa (total 104% 🤯). Numbers largely speak for themselves, with relatively stable figures for bystanders (EU, also BRICS) hiding significant trade diversion. 1/3

The Kiel Institute is on fire – they modelled the impact of Trump’s trade war. Check out the chart. The numbers come with the usual uncertainty, but they give a good sense of the eye-popping inflation the US is now facing. Via @davideoneglia.bsky.social Paper here: www.ifw-kiel.de/topics/kiel-...

🚨 KITE Insta-Analysis: New "reciprocal" US tariffs are serious. We ran both status quo (tariffs until April 2 incl. retaliation) and newly announced reciprocal tariff regime through the KITE model. (Non-) spoiler: 🇺🇸 hits itself the hardest. NB: Short-run, extremely ad-hoc. 1/n

🚨 KITE Insta-Analysis: President Trump just announced an additional 25% on US automotive imports. While the industry has global visibility, short-run impact likely small, except for 🇲🇽 Mexico and 🇨🇦 Canada: -1.81% and -0.6% real GDP impact. Even Germany only -0.18%. Note: No retaliation here. 1/n

Translation of Trump's 232 autos executive order... 1. Are you bringing cars into the US? 25% tariff for you 2. Are you bringing parts from our special list into the US? 25% tariff for you

🚨 KITE Insta-Analysis Update: President Trump just announced an additional 25% on Canadian imports of steel and aluminum, bring the total to +50%. Overall effects similar, except for Canada: -0.62% vs. -0.39% real GDP impact. Note: No retaliation here.

1/ Trump's new 25% steel & aluminum tariffs hurt the US most—raising prices & cutting exports—while the EU remains largely unaffected. Canada & Mexico, however, face substantial repercussions @julianhi.nz 👇
