NEW YORK SHARES

Leaders of the G20 economies are preparing to endorse a communique pledging further action on growth, increased resources for the International Monetary Fund and fresh commitments by the European Union to do more to integrate to solve its problems.

The G20 leaders representing 80% of the world economy are meeting in the luxury resort of Los Cabos, Mexico, against a backdrop of incessant economic storms, mainly coming from the eurozone.

Plans for an after-dinner meeting between the US president, Barack Obama, and the leading four eurozone countries attending the G20 were scrapped officially because the issue of the eurozone had been discussed enough.

There may also have been fears that tensions were starting to escalate between eurozone leaders, notably the two EU figureheads, José Manuel Barroso and Herman Van Rompuy, and other G20 countries about the slowness with which the EU was addressing its problems.

In a sign of the tensions, the Italian prime minister, Mario Monti, said no one thought the EU was "the only source of the problem". The crisis "had its origins in imbalances in other countries, including the US", he said.

Among the commitments in a draft G20 communique, which emerged on Tuesday, was a pledge to consider concrete steps towards a "more integrated financial architecture" in Europe that would include common banking supervision and firm guarantees to repay bank depositors.

The G20 communique states that euro-area members of the G20 "will take all necessary policy measures to safeguard the integrity and stability of the area, improve financial markets and break the feedback loop between sovereigns and banks".

The US, the IMF and European commission have been urging EU member states to press ahead with a banking union.

The term banking union does not appear in the text, but the wording suggests Germany may be willing to shift a little in further talks due to be held between EU leaders both in Rome on Friday and then at a full gathering of EU heads of state in Brussels next week.

In the most substantive development, the emerging countries agreed to increase funding for the IMF in a move that will see changes in the composition in the board of the IMF in return.

China, Brazil, Mexico, India and Russia all announced contributions to the IMF to bolster a "second line of defence". China will contribute $43bn (£27.4bn), the official Xinhua news agency reported. The others' share was $10bn each.

In total, the IMF's crisis intervention fund has been increased to $456bn.

Britain is not making any further contributions after already increasing its funding in the spring.

There were fears though that the resources would still not be enough to deal with the crisis.

"There is concern that the firewall available may not be adequate to deal with contagion," the Indian prime minister, Manmohan Singh, said at the summit. "The resources currently expected to be mobilised by Europe and the IMF are less than was estimated a year ago, and the crisis is actually more serious."

He added: "Financial markets normally favour austerity, but even they are beginning to recognise that austerity with no growth will not produce a return to a sustainable debt position."

In a message to Germany, he added: "Austerity in the debt-ridden members of the eurozone can work only if surplus members are willing to expand to offset contraction elsewhere in the currency area."

Conflicting messages were coming from Germany as to whether it was willing to delay Greece's current bailout plan.

The German chancellor, Angela Merkel, took a tough line, saying there could be no backsliding in the previously negotiated timetable, but other German leaders sounded a more flexible note.

Greece must achieve a budget surplus, excluding debt-service costs, of around 4.5% of gross domestic product from 2014 onwards, compared with a deficit of 5% in 2011. Athens is expected to ask to be given until 2016 to achieve the target. A slower timetable would add to borrowing needs in the meantime.

Obama met Merkel on the fringes of the summit to press her to do more. With the US election only five months away, he is desperate to see the gloom lift from world markets.

"The president was encouraged by what he heard regarding ongoing discussions in Europe about the paths they are pursuing to address the crisis," the White House spokesman Jay Carney said.

David Cameron, the British prime minister, is due to lead a G20 discussion on trade on Tuesday, warning of the dangers of protectionism, and arguing that ending trade barriers may be one of the best ways to boost growth at a time when governments cannot afford to boost spending.

The Russian president, Vladimir Putin, showed a determination to go in the opposite direction, saying: "It is time to stop pretending and come to an honest agreement on the acceptable level of protectionist measures that governments can take to protect jobs in times of global crisis," he said.

"This is particularly important for Russia as our country will join the WTO this year and we intend to take an active part in the discussions on the future rules for global trade."

Campaigns that were just getting excited at the prospect of vacuuming up cash through text messaging, which the Federal Elections Commission green-lighted on June 11, may have yet another way to collect donations with a couple taps of the keyboard. Up to 140 taps, that is. Chirpify, a social-commerce startup based in Portland, Ore., has rolled out a site called Tweetlection at which donors can send money to Barack Obama and Mitt Romney via Twitter.

The process seems simple. All you need do is create an account with Chirpify, link it to your PayPal (EBAY) and Twitter accounts, and you could donate up to $200 instantly, just by tweeting “Donate $200 to @MittRomney for POTUS.” You log into Chirpify only once for the account setup, and then use Twitter, TweetDeck, or any other tweeting app as you normally would. ”There’s no shopping cart or checkout process,” says Chris Teso, Chirpify’s chief executive officer. “We’re calling it conversational commerce.”

The startup processes donations through PayPal. For the presidential candidates to collect the money, though, there’s a catch: Teso says they’ll have to create their own, free Chirpify accounts to cash in. If they don’t, your credit card won’t be charged. (Neither campaign has responded to a request as to whether they’ll participate.)

Teso says neither Romney nor Obama has signed on to a bigger deal with Chirpify that would let their campaigns collect more money in exchange for Chirpify’s 4 percent fee per contribution. That’s obviously the company’s hope. At least two dozen Republican senators and members of Congress will announce in the coming weeks that they’ll use Chirpify to solicit donations by tweet, Teso says. (He won’t name them.) Under those deals, campaigns can collect as much money as they want per tweet and Chirpify will supply them with information required by the FEC (i.e., donors’ full names, addresses, and occupations). The service could end up being a lot less costly than fundraising via text message, which the mobile payment aggregator known as m-Cube plans to roll out this summer at fees of up to 50 percent per donation.

Chirpify went live four months ago and is primarily used by individuals paying off IOUs. (As in: You didn’t have enough cash for your beer tab last night and need to pay back a friend today.) Teso says the company is also processing donations for the Make-A-Wish Foundation and running promotions for companies including Nestle (NESN:VX) , Power Bar, Pawngo, Sir Richard’s Condom Co., and Hewlett-Packard (HPQ). Those brands can advertise products to their Twitter followers, who can then place an order for a product by tweeting the word “buy;” Chirpify then coordinates with PayPal and the vending company to get the product paid for and shipped out.

Teso says the startup has tens of thousands of members and that “over 50 percent … have transacted in one form or another. That could be purchasing, donating, or paying you for dinner last night.” That’s nothing compared with Barack Obama’s 16.7 million followers, or even Romney’s 563,000. So far, though, their Twitter brigades aren’t exactly flooding Tweetlection. The site rolled out Tuesday; by noon Romney had $150 in pledges—and Obama just $132.
