LONDON, April 2 (Reuters) - What matters in U.S. and

global markets today

By Mike Dolan, Editor-At-Large, Financial Industry and Financial

Markets

The bigger the buildup to an event, the greater the risk of

disappointment. Wednesday's much-heralded U.S. tariff

announcements might not live up to the hype, but even if they

do, this is not going to be the end of the matter, and the

market reaction won't be cut and dried either.

I'll discuss how markets are reacting in advance of the big

reveal and then explore the risk investors should be focusing on

right now. Hint, it's not a tariff surprise today.

Today's Market Minute

* U.S. President Donald Trump is poised to impose sweeping new

reciprocal tariffs on global trading partners today, upending

decades of rules-based trade, threatening cost increases and

likely drawing retaliation from all sides.

* Drugmakers are lobbying to Trump phase in tariffs on imported

pharmaceutical products in hopes of reducing the sting from the

charges and to allow time to shift manufacturing, according to

this Reuters exclusive.

* Reuters takes a look at past examples of eras dominated by

tariffs and at how they've affected prices and trade.

* The U.S. administration is planning an executive order that

would loosen the rules around exports of military equipment,

just as Europe is rearming at the fastest pace in at least 80

years, according to four sources familiar with the discussions.

* One of the world's largest auto part suppliers is preparing

for Trump's tariffs by "controlling the uncontrollable" as the

industry faces a seismic shakeup.

Trouble with a capital 'T'

The timing of the Rose Garden set piece laying out Donald

Trump's long-awaited trade strategy is now pencilled for 4 p.m.

Eastern Time today.

Various reports have circulated indicating that Trump will

be announcing 20% across-the-board import tariffs, but other

reports have talked of a tiering system. No one, including

financial traders and investors, seems fully sure of what is

coming.

Perhaps prepping for all outcomes, Wall Street stocks rose

slightly on Tuesday as the second-quarter got underway, though

they still underperformed their European peers. But

S&P 500 futures gave back those gains overnight, and most

world markets were slightly in the red on Wednesday.

The VIX "fear index" was around 22, above historical

averages but still well shy of the 7-month high near 30 set a

month ago.

Whatever the outcome later today, there is likely to be a wave

of retaliatory tariff measures, which have been less discussed

in analyses of the potential worldwide impact of the U.S.

tariffs.

ISM's March manufacturing readout on Tuesday showed U.S. factory

activity slipping back into contraction last month, with price

expectations surging. And job openings fell in February, a nervy

start to the week's big labor market updates.

March payrolls are coming on Friday, and the ADP private

sector job tally is due later today.

While the futures markets continue to price in three Federal

Reserve interest rate cuts this year, it's interesting that five

are priced by July next year despite the tariff-related

inflation jitters. That would take the policy rate back to where

Fed officials see the long-term neutral rate.

Treasury yields were a touch higher early

Wednesday, however, and the dollar index was a tad

weaker.

In other non-tariff political news, Wisconsin voters elected

Susan Crawford to the state Supreme Court, maintaining the

court's 4-3 liberal majority in a setback for Trump and his

billionaire ally Elon Musk, who had backed her conservative

rival.

In better news for the administration, however, Republican

candidates are projected to win two special elections in

Florida, which would boost the party's slim majority in the

House of Representatives by filling vacancies created by Trump's

picks for cabinet posts.

And now I'll turn back to tariffs to explain why a "crash,

bang, wallop" surprise today is not the risk investors should be

most worried about.

Tariff shock less worrying than slow burn

The still mysterious U.S. tariff sweep coming on Wednesday makes

it tough for investors to see much beyond this week, but the

real risk is more of a slow-burning U.S. market decline on some

open-ended plan - seeding months more of uncertainty rather than

a cathartic one-off.

Most medium-range market forecasting has simply been abandoned

over the past week, as strategists have no tariff baseline to

work with. Guesswork has ensued for the most part, while a lousy

quarter-end funk descended on Wall Street and implied volatility

gauges crept higher.

The size, shape and duration of the tariffs are all unknown,

and the breadth of countries affected remains up in the air.

If the big announcement on Wednesday does come as some

"crash, bang, wallop", that could at least clear the air on Wall

Street, which has been on tenterhooks over the issue all year.

In fact, analysts looking at the elevated but relatively

contained pricing of stock index volatility suggest that there's

little left to come out on Wednesday that truly surprises and

pushes those gauges up much further.

Maxwell Grinacoff, head of equity derivatives research at

UBS, made the case on Tuesday that tariffs were now well priced

into the S&P 500 index and that investors had

substantially "derisked" in March by selling equities in lieu of

hedging.

This trend led to sharp equity price declines, but a more

modest reaction in "vol", especially when compared to

some of the periodic spikes in the "fear index" seen during the

bull market of recent years.

"Volatility is now having its 'dirty-shirt' effect - it's

already stained, so a little more 'mud' won't do much else,"

wrote Grinacoff, adding that VIX levels were likely to remain

range-bound around 20 as a result.

MARKET LAUNDRY

The prospect of the tariffs announcement on Wednesday

clearing the decks then could be considered a positive, but only

if you're generally bullish about the U.S. economic outlook.

"We think the potential for even higher volatility from here

is thus limited," Grinacoff added. "Unless the U.S. falls into

recession territory over the coming months/quarters - albeit not

our base case."

Absence of recession is a big caveat.

Goldman Sachs joined JPMorgan this week in arguing that the

chance of recession in the U.S. over the next 12 months has

risen markedly. Goldman gives it slightly more than a

one-in-three chance, a tick below the 40% JPMorgan now sees.

What's more, GDP models are already indicating a first-quarter

contraction. The Atlanta Fed's headline "GDPNow" forecast is

pointing to a whopping 3.7% annualized shrinkage of national

output in the first three months of this year. Some of that is

clearly distorted by gold imports, but the Atlanta Fed's

gold-adjusted estimate is now clocking a contraction of 1.4%.

High-frequency data on Tuesday did little to brighten the mood.

ISM's manufacturing survey for March showed the factory sector

slipped back into contractionary territory, and falling job

openings suggest cracks are appearing in the once-watertight

labor market.

And no matter what happens this week, markets are still

likely to face lingering doubts about the trade war endgame and

the unknowable lagged effects of the import levies on prices,

demand, hiring and activity. So it's hard to see how the tariff

boil gets lanced this week.

Trump's administration retains the right to extend, hike,

postpone or even cancel the tariffs as part of its high-pressure

dealmaking on a range of thorny issues with both allies and

rivals.

And it is also impossible to know how the rest of the world

will react and retaliate to the U.S. actions, a factor in the

looming trade war that is often underplayed.

So economists should have more to work with after Wednesday,

but crystal clarity may be stretching it.

And it's this long-term uncertainty and gradual economic

weakening - a slow burn - that may be truly corrosive for

already bruised and still expensive equity markets.

Chart of the day

We're seeing the perfect storm that gold buyers have dreamt

of for years - well, almost 40 years. Trade wars, military

tensions, broken Western alliances, inflation concerns,

recession fears and doubts about the dollar's dominant role in

world finance: The combination of all this has seen gold

zoom nearly 20% so far this year to an all-time high of $3,148

per ounce. It's been its best quarter since 1986.

And this time around U.S. protectionism and isolationism are

also in the mix. With tariff walls and military spending rising

and the spectre of "stagflation" lurking in the background,

central banks around the world have boosted gold holdings at the

margins as part of their precautionary reserve building.
