UniCredit stock (ISIN IT0004781412) ended Borsa Italiana trading at EUR 81.13 on September 18, 2026, roughly 3 percent below the prior close as Italian equities sold off into the end of the week. As of September 18, 2026, the shares were still markedly above their 12-month low and remained supported by robust capital markets activity.

AT1 bond placement draws strong demand

According to Teleborsa on September 18, 2026, UniCredit placed a perpetual additional tier 1 (AT1) bond with a nominal amount of EUR 750 million, attracting orders of more than EUR 3.5 billion from over 220 investors worldwide.

The guidance for the new instrument was initially indicated in a range between 6.625 percent and 6.75 percent, but the strong book allowed the bank to tighten pricing and set the coupon at 6.25 percent, with a reset margin of 284.1 basis points, described in the report as the lowest margin UniCredit has ever achieved for this type of instrument.Teleborsa This means investors accepted a lower spread over the reference rate than in previous UniCredit AT1 deals, a signal of confidence in the group’s capital position.

Share price reacts to weak Milan session

Price data from Milan show the stock closed at EUR 81.13 on September 18, 2026, after starting the session at EUR 83.18 and sliding towards the day’s lows by the end of trading.Teleborsa The same technical commentary notes that the stock’s intraday deterioration left it near the bottom of the day’s range.

Across the broader Italian market, losses were widespread. As Trading Economics reported for the FTSE MIB on September 18, 2026, UniCredit shares fell 2.83 percent during the session, while other heavyweights such as Stellantis and Hera also posted sizable declines.

Weekly performance and sector comparison

The week’s movement left UniCredit among the significant laggards in the Italian blue-chip universe. A weekly performance table published by MarketScreener on September 19, 2026 shows UniCredit with a weekly decline of 4.74 percent, compared with a 1.84 percent weekly loss for the FTSE MIB index itself.

In that same overview, several Italian peers posted gains or milder losses, underlining that UniCredit’s drop was among the more pronounced moves in the financial sector over the week.MarketScreener For investors, this combination of a successful AT1 issuance and a relatively sharp share-price setback makes the balance between capital strength and earnings prospects a central point of attention.

Market context and investor implications

A broader review of European markets highlights that Milan underperformed its regional peers over the week. An English-language market wrap from Il Sole 24 Ore dated September 18, 2026 notes that Milan closed the week down 1.8 percent, with UniCredit shares off 4.7 percent despite reported progress on a potential Commerzbank transaction.

For shareholders, the picture is therefore mixed: UniCredit is able to raise EUR 750 million of AT1 capital at the lowest margin it has yet achieved for such instruments, yet the stock moves sharply lower over the same period, underperforming the index by roughly 3 percentage points on a weekly basis.MarketScreener The discrepancy suggests that market participants are weighing potential deal execution and macro risks, even as the group’s capital-raising capacity remains intact.

Stock level and recent trading data

Per Milan price data as of September 18, 2026, UniCredit stock closed at EUR 81.13, with an intraday high reported at EUR 83.18 before sellers took control later in the session.Teleborsa That closing level stands noticeably below the weekly starting point implied by the 4.74 percent loss in the MarketScreener overview.

Detailed figures for market capitalization, 52-week range and trading volume are not broken out in the available week-filtered sources, but the combination of a falling share price, a sizeable AT1 deal and a weak FTSE MIB performance provides investors with a concrete snapshot of how UniCredit is navigating the current rate and regulatory environment.
