【正文】 for the fifth time.
　　Lord Mayor, I remember ing here to Mansion House, just weeks after the government wasformed in 20xx amp。s problems with long term answers that will build an economy foreveryone.
　　So while I know this is my fifth speech to you as Chancellor。rsquo。ndash。rsquo。rsquo。t learn the lessons of the past.
　　So we act now to insure ourselves against future problems before they can materialise.
　　Because economic security es first.
　　The first challenge is to be clear about the issue, and we are.
　　The second is to act on it.
　　When I spoke to you in 20xx, I said one of the weaknesses of the system of financialregulation Iamp。fought and controversial, like all things worth battling for in politics,and now they are already starting to work.
　　Last week we saw permissions for new homes rising by 20% in a year.
　　Weamp。rsquo。 local authorities will be able to specify the type of housing, not whether thereis housing.
　　And it will mean planning permission for up to 200,000 new homes amp。ve taken big new steps to protect financial stability, strengthen the new role ofthe Bank of England and pleted the range of tools at their disposal.
　　This addresses the economic problem of how we stop rising house prices leading to anunsustainable rise in household indebtedness, and threatening the wider economy.
　　But it does not address the social problem of how we stop young families being priced out ofthe housing market altogether.
　　That requires a third pillar to our housing strategy, alongside the clear analysis and newfinancial weapons.
　　We need to see a lot more homes being built in Britain.
　　The growing demand for housing has to be met by growing supply.
　　The alternative, as in any market, is that prices will rise so that homes bee unaffordable tomany of our citizens and take up ever more of their ines.
　　Weamp。s how.
　　First, we have to be cleareyed about where the risks to economic stability lie today.
　　The risks e when people borrow too much to pay for rising house prices.
　　In excess, that debt can cause serious difficulties for them and the banks who lent to them.
　　And it can cause difficulties for the economy as a whole if an overhang of debt suppressesconsumer spending.
　　Now, today, house prices are still lower in real terms than they were in 20xx amp。s housing market.
　　Instead we have the repeated cycle of financial instability driven by high household debt。rsquo。 45% of overthecounter derivatives trading。pound。 and there are many risks to the progress we have made.
　　Abroad, the risks stem from the weak eurozone, unpredictable geopolitics and the slowdownin some emerging markets.
　　At home, our economy is still too unbalanced, so I am the first to say we need to continue ourefforts to boost business investment, exports and housing supply.
　　But the biggest risk es from the tendency in parts of our body politics amp。ndash。 I hope it is not my last.
　　For I want to finish the job.
　　Lord Mayor, tonight we are joined by someone attending their first Mansion House dinner.
　　Our Governor of the Bank of England.
　　Mark, we all thank you for the integrity, intelligence and international reach you have broughtto the challenges of the last year.
　　And we look forward to what you have to say.
　　Our 3 new Deputy Governors amp。s largest insurance firms.
　　And we have been chosen as the location for the International Forum of the worldamp。 many of which are currently entirely unregulated.
　　Based on the Reviewamp。t sit fortably together.
　　For most people, their home is the biggest investment of their lifetime. And, of course, theywant that asset to increase in value over time.
　　But a home is also a place to live and build our lives amp。m determined to back aspiration in every way I can, including the aspiration to own yourown home.
　　But Iamp。rsquo。rsquo。re pulling up the property ladderbehind us.
　　So we will build the houses Britain needs so that more families can have the economic securitythat es with home ownership.
　　And today I will give the Bank of England the powers it needs over mortgages, so that Britainam
