to joins me from new york. hi jens. yes. how worrying is what's going on with 1st republic? yeah, maria, desperate time stephanie lee call for desperate to measure says so when we got to word that obviously m almost a dozen of from usaa banks are jumping him to an end to get a deposit stu 1st republic. him that did definitely cause so quite it would change . sure. but then again, i mean to think about it as sort of competitors helping another bank to stay afloat . that is of what i would call a desperate measure. i mean, the stock did turn around into is saw some decent gains in the so stay station. but now in after our trading, the stock is actually down again a buy at 20 percent of the management and hinted that it's not going to pay any a dividend. so those are definitely, well, i'm not sure if it's necessarily um,

the head of the treasury that com market said down of what definitely helped earlier this week is, is when the federal reserve for the, if the i c as said that they're actually a guaranteeing and money for a banks here in the united states. so what we need at this time is, is time because with all those financial institutions have to rebuild a trust them and that it takes time. and so to get this time, or we heard from switzerland, for example, from the national bank, i'm over there that they're guaranteeing as some money afford credit suisse. and then we have something similar here in the united states. so either from other banks or also from authorities here. so that's what everybody tries to do, build up confidence to buy some time is so that the banks can sort things out. it will be successful in every financial institution. it can be safe, there remains to be seen. yes, carter with a closing bell in the background. there are thank you very much. and meanwhile,

here in europe, the european central bank has stuck to its plans to raise interest rates by half a percentage point bringing it to 3 per cent. it's president castilla god said the decision was a robust move designed to bring inflation under control. she dismissed war is about the european banking system, saying the c b would provide additional support if needed. she was speaking just hours after switzerland central bank extended a credit lifeline to troubled lender credit suisse. for more, i'm joined by my colleague my to freshman. notice the easy be made this announcement announcement in the midst of financial turmoil. what are the considerations that central bankers are weighing off before making such an announcement? well, i think it's helpful to understand that central banks are quite weird. public animal, right? they sort of rely on the financial system that they regulate to actually do their

policy. so if they break things, they can't raise interest rates anymore, and they need to do that to rent in inflation. so that's a very tough path. they have to struggle with here in trying not to do too much and but actually at the same time actually doing something. ok, so it's a juggling act really here. some analysts expected the c, b to only raise interest rates by a quarter percentage point because of the banking turmoil that the u. s. and the a and europe are experiencing right now, but they didn't. they went for a half a percentage point. why is that? you think so a central bank needs credibility, right? the probably needs to trust that it actually performs on the job that it's set to do. and that's keeping the inflation target. and the european central bank has repeated often in the past to do this 50 percent of 50 basis point rate hike. and so they can't just move away from doing that. and now they did it,

but they've also scraped all this forward guidance from their, their statement to days. so they're, they didn't commit to anything for the future, which is something they usually have done in the past meetings. so the now want to see how the financial economic data evolves to make any more decisions. okay. um, so its goal, the seabees goal is to reduce inflation to 2 percent, ideally out. how realistic is that at this point? the c b itself says they're expecting inflation at 5.3 percent for 2023 and 2.9 percent for next year. so they're overshooting their own target. there is some wiggle room there because they've changed their stands and policy there so they can over should slightly. but it shows they're not really performing on their job. and these projections have been wrong in the past. so we also have a situation where profit margins of companies actually are pushing inflation.

that's something that used to be can't do much about. and there have been drops and energy prices, which has been helpful in the past. but food prices have still risen. so we have the still, this environment that the it is grappling with and it's clear how they're actually going to manage to calm down difficult environment. but higher interest rates never the less much us higher interest rates are also part of the reason behind the collapse of silicon valley bank last week to higher interest rates in europe. mean, we're heading towards more collapses of regional banks. so the problem here is that historically interest rate hikes have let to recessions. that's just a fact. and the c b has a particularly bad track record. they raise interest rates in 2011 just as the euro crisis was getting started. they are aware that christina la guard mentioned this and her speech today,

so they know that they're in difficult her territory and regulation has strengthened, banks are much sondra state now. so we're in a different point now where we will hope that things won't break as much. ok, so a precarious situation. thank you so much. not a statement from d. w business. now on to some of our other global business stories making news, interest rates are in a completely different league in argentine, our, the central bank has raised them to a whopping 78 percent. the $300.00 basis point increase comes after year on year inflation exceeded 102 percent and february reaching triple digits for the 1st time and over 3 decades. now, she long as economy shrank. a record 7.8 percent last year, long blackouts and critical fuel shortages have thrown the country into an

unprecedented economic crisis. the government is currently trying to secure a bailout by the international monetary fund. it's raising taxes and ending subsidies in an effort to fix its finances. japan and south korea have agreed to settle a long standing trade dispute at a meeting in tokyo. de panel lift export controls on chemicals vital to south korea, chip industry. meanwhile, sol will drop a w t o complaint against japan. now could an energy revolution also come from europe, rooftops? tesla, ellen, musk one set of sites on crating ceramic tiles, the doubled a solar panels. but now a young german company appears to be giving the billionaire a run for his money. will their invention help to top up europe's energy transition? let's take a look. this house is getting a new roof and there's something special about it. it's made with solar tiles like

regular tiles stay provide a shield from the elements, but they're also capable of generating power. they're produced by out arc, a start up from prince loud in eastern germany. now and we can make a simple calculation example of 1000 tiles under roof at the peak of 10 kilowatts fennel in brazil, depending on the location in germany, you can get about 9000. sometimes 10000 kilowatt hours are coming down every year and kind of the initial investment in pay for itself in about 20 years. the investment is a sizable one though, compared to solar panels attached on top of a normal roof. our talks, a solution can cost several 1000 years more. that's because solar tiles are still manufacturer and on a small scale in this factory with a process that involves a lot of manual labor. despite the higher price, more and more customers are expressing their strong interest in the technology,

boise, our customers of a friendly approach. they're interested in trying something that excites them, or they're interested in the aesthetics of our solution. plus we were able to come with them. thanks to our product safety features, the interpreter wants to produce more and bring down costs at the same time. to do that, the company's automating production with more and more robots in order to handle the upcoming expenditures. the owners brought new investors on board for the startup. it's the leap of faith. them last year we double our revenue to 5000000 this year. we aim to increase it fivefold. even 6 hold german homeowners tend to be price conscious, though it might still take some time for them to fully embrace this new technology . and a reminder of our top story. shares and 1st republic bank tumbled 35 percent in early trading on worries about solvency. the news of a rescue package from
