The shock that changed the financial world forced a safety-first approach that appears to have come at a price, writes Clancy Yeates.
It was the corporate collapse that shook global finance to its core. Former US Federal Reserve chairman Alan Greenspan dubbed the bankruptcy of Lehman Brothers and its fallout a "once-in-a-half-century, probably once-in-a-century type of event".
A top Australian banker describes the investment bank's demise as the moment when credit markets realised "banks can go broke".
"In the past, as a bank you could basically borrow as though there was no risk," the banker says.
When the once-venerable US bank filed for bankruptcy five years ago this weekend, it triggered a wave of panic and an unprecedented freezing up in the global financial system. Its legacy still lingers around the world today, including in Australia.
A third of the value of the ASX 200 was wiped off between September and November 2008, destroying hundreds of billions of dollars in retirement savings.
Even though the market is now back to where it was before the Lehman collapse, BT Financial chief economist Chris Caton says the crash fundamentally changed the way many Australians view stocks.
"They thought the sharemarket was a get-rich-quick machine, but they've also discovered it can be a get-poor machine," he says.
"Investors are still very gun-shy even five years later, because they feel they've taken a real hit."
But the bruising of investor sentiment is just one of many impacts still working their way through the financial system.
The big four banks - which hold about $1.5 trillion in loans - have been forced to make sweeping changes to their business models. Profits are still growing strongly, but the sector faces a future where credit will not expand nearly as quickly as it has in the past.
Credit markets have also changed fundamentally. While confidence is recovering, investors are deeply dependent on support from central banks - something that must inevitably be withdrawn.
This patchy recovery since Lehman's fall has left global authorities in the middle of a delicate balancing act, with a financial system that is safer and more stable, but also less competitive and dynamic, and potentially a drag on future growth.
While Australia dodged the worst of the 2008-09 global recession, Lehman's collapse and its aftermath continue to have far-reaching consequences for the country's financial system - in particular, the big four: Commonwealth Bank, Westpac, ANZ and National Australia Bank.
As industry insiders see it, two monumental changes stand out. One is how the banking system funds itself; the other concerns global regulation.
Over the 1990s and early 2000s, the business model that was increasingly driving banks' growth involved borrowing from large investors, instead of depositors, and then lending the money.
When markets stopped trusting the banks after Lehman's demise, this supply of wholesale money threatened to dry up. They have since been forced back towards the traditional model of raising money from depositors.
Ian Harper, a panel member of the Wallis review of the financial system in 1997, says this change has been one of the most critical shifts of the past five years.
"Prior to Lehman Brothers, you would have expected that capital markets would continue to grow and that balance sheet borrowing and lending - that is to say taking deposits and making loans - would shrink," he says.
"Lehman Brothers turned that on its head. Now, five years later, balance sheet banking, good old traditional taking deposits and making loans, is more important than it's ever been," Harper, a partner at Deloitte Access Economics, says.
Prime Minister Kevin Rudd's immediate response was to guarantee banks' wholesale liabilities with the government's AAA credit rating, but the longer-term response of banks has been to scramble to get their hands on more deposits.
Since mid-2008, consumers have ploughed $239 billion into bank deposit accounts, boosting the value of total household bank deposits by 55 per cent.
The share of bank funding that comes from deposits has surged from about 40 per cent in 2008 to almost 60 per cent today, a shift bankers say should not be underestimated.
So far, this trend has gained high publicity because banks have blamed it for not passing on interest rate cuts to borrowers in full.
But bankers predict it will have much wider consequences for the economy in the long term. Most new loans must now be funded by deposits, which could put a brake on growth when credit demand picks up.
The other critical change is tougher regulation.
Under rules set by banking regulators, lenders around the world are being forced to hold much higher amounts of capital, or shareholder equity, to absorb losses.
The Australian Prudential Regulation Authority, which prides itself on being conservative, is implementing these rules before some other countries, sparking complaints within the banking industry.
Harry Scheule, an associate professor of finance at University of Technology, Sydney, describes the new rules, known as the Basel III regime, as the most important changes to the financial system since Lehman's collapse.
"It will most likely bring down return on equity for banks," he says. "It will make banking less profitable but much safer because it means that banks have to cover future losses."
So far, profits of the big banks have not been meaningfully squeezed by the changes - return on equity in the sector is still a healthy 15 per cent and their profits are on track to exceed $26 billion this year.
But the Reserve Bank has repeatedly told banks they can no longer expect to rely on rapid growth in their balance sheets to expand profits.
The RBA's assistant governor responsible for the financial system, Malcolm Edey, stressed this point in a speech in March. "On any reading, it seems clear that this will be an environment where it is harder in general for banks and for the system as a whole to grow," he said.
Bankers also say the tougher regulations are a likely constraint on future growth in credit - and hence the economy. "For every dollar of capital, we will be able to extend less credit next time than we were able to last time," one says.
Triple T Consulting managing director Sean Keane points out that the global regulatory push has encouraged residential lending rather than business because home loans receive more lenient capital treatment.
"There's much more caution among the commercial banks in Australia about lending for non-residential mortgage purposes," Keane says.
For all of the tougher regulations, however, an important effect of the changes has also been to concentrate power among the big banks.
After swallowing former rivals such as St George, Bankwest, Wizard and Aussie Home Loans, the big four enjoy about 80 per cent of the market in deposits and loans.
Harper says they are now the most powerful they have been for decades, a theme that is likely to feature in the Coalition's planned financial system inquiry.
Against this, the system is also more stable than it was before Lehman's fall. Banks have more capacity to absorb losses, more stable funding sources, and they have so far been more cautious in their lending.
It is often said regulators must trade off between competition and stability when setting the rules for a financial system. After the Lehman shock, they have opted for stability.
Changes in Australia are only part of the story, however.
As an importer of capital, the country is strongly affected by global credit markets that virtually froze when Lehman collapsed. Conditions on these markets have improved dramatically from the lows of the global financial crisis.
A gauge of the global risk of lending to 25 of Australia's biggest companies, the iTraxx index, now trades just 110 basis points above the benchmark, compared with the spread above 400 at the worst of the crisis.
Bullish investors this week also pushed the ASX 200 to five-year highs.
"It's not back to where it was, but it's a whole lot better than it was and it's out of the danger zone," Nomura interest rate strategist Martin Whetton says.
"Five years ago if you were a bank, you could not borrow on the capital markets, you had to use the government guarantee," he says. "You don't need the sovereign balance sheet any more to raise money.
"The 30,000 foot view is that we had those problems but they've been largely patched over by the amount of liquidity that's been injected into the system."
Reflecting this improvement, he says the yield on 10-year bonds issued by the Irish government - one of the worst hit during the financial turmoil - is almost level with Australian government paper.
"It's not just about safe havens any more, it's about yield. It shows that the risk in the 'bad' parts of the world, like Europe, has abated really substantially," he says.
But while confidence has lifted, markets are far from standing on their own feet. Investors are being supported by central banks pumping billions of dollars worth of cheap credit into the market every day.
Keane says the improvement must be seen against "ongoing massive central bank support".
"The degree to which markets have wobbled in the last couple of months on the mere mentioning of tapering by the Federal Reserve gives you a real sense of the degree of reliance markets continue to have on the central banks," he says.
In the past six years, central bank balance sheets globally have swelled from $US10.4 trillion to $US20.5 trillion ($22.1 trillion) as money printing has been unleashed in full force. The Bank for International Settlements warned in June that investors had become "overdependent" on this type of stimulus, and it was time for banks to wind the measures back.
But the very threat of withdrawal has created its own set of headaches.
The first mention of "tapering" in the Fed's $US85 billion a month bond-buying program triggered a spike in Treasury bond yields earlier this year, which has in turn caused speculative capital to quit some regional economies, especially Indonesia and India.
Next week - when some analysts believe the Fed will make its first moves to "taper" - looms as a potential test for how markets cope with less central bank support.
Five years on from Lehman, the world's financial system is undoubtedly on the mend. Propped up by central bank balance sheets, investors have regained the confidence needed for credit to flow around the world.
Despite fears over central bank support being withdrawn, markets are a long way from the days when there was indiscriminate panic over the prospect of bank failure.
Australia has also emerged with a more stable system that is likely to be increasingly resilient in the face of a future crisis.
Yet it is also subject to tougher regulations, and is a more concentrated industry. Critics say it is less competitive, which risks stifling innovation.
The role of finance is often likened to grease in the wheels of the economy. At some point in future, bankers say this more conservative and tightly-regulated financial sector could become a drain on economic growth.
After the shock inflicted on the world five years ago, however, sacrificing slightly slower credit growth for greater safety is a trade-off that governments are more than happy to make.
