The price of bitcoin is a capricious thing. Imagine that you've saved enough bitcoin to take your significant other out to a fancy restaurant. When the bill comes you discover to your horror that the price of bitcoin has crashed sometime between main course and desert. For the next few hours you're both stuck doing the restaurant's dishes. Far less embarrassing to choose dollars as your payment media at the outset given the unlikelihood of a dollar crash. This has always been one of bitcoin's main problems. The burden that a consumer must endure in absorbing bitcoin's incredible volatility until the time of payment outweighs any reduction in transaction fees that they might enjoy. Or maybe not. Marc Andreessen recently posted a number of thoughts on twitter. The most interesting ones are #9 to 17, namely that bitcoin's fabled volatility needn't deter regular folks from using it as a cheap and fast payments mechanism. 15/For example, payment applications of ...

The upcoming Greek election has renewed interest in the idea of Grexit. This option is often presented to the Greek public as desirable given that it would restore an independent monetary policy to the nation. Beware, this is dangerous advice. The euro isn't a glove that you can take on and off, it's a Chinese finger trap; once in, it's tricky to get out. Even if Greece were to formally leave the euro, odds are that it would remain unofficially euroized, leaving it just as bereft of an independent monetary policy as before. The real trade off in a Grexit-or-not scenario is between formal membership in the euro with some say in monetary policy, no matter how small, or informal membership without any say whatsoever. The optimists, say someone like Hans-Werner Sinn , advise the Greeks to leave the euro and adopt a new currency. The value of this new drachma would immediately collapse. As long as prices in Greece are somewhat sticky, Greek goods & services will become incre...

Swiss National Bank share certificates Gavyn Davies blames the Swiss National Bank's corporate structure for the floating of the Swiss franc. Paul Krugman intimates the same, as does Cullen Roche . Here is Davies: But the SNB is 45 per cent owned by private shareholders, many of whom are individuals, who receive dividends from the SNB. The rest is owned by the cantons, which have been complaining recently about insufficient cash transfers from the SNB. Davies goes on to say that the influence of shareholders, combined with the peg, means that the SNB is particularly concerned about balance sheet losses. The idea seems to be that currency pegs often result in large balance sheet fluctuations, forcing a suspension of shareholder dividends. I disagree, as a quick peek at the details shows: 1) The dividend to which Davies attributes so much importance is minuscule. In aggregate it comes out to just CHF 1.5 million per year, or US$1.7 million . Private shareholders, who own just 40.3%...

Two things worth noting: As many of you know by now, the Swiss National Bank (SNB), Switzerland's central bank, just reduced the rate that banks earn on deposits held at the SNB by half a percentage point to -0.75% (from -0.25%). The SNB had only recently instituted a negative deposit rate, having reduced it to -0.25% from 0% this December. The SNB will also be targeting a 3-month LIBOR rate of -1.25% to -0.25%, down from the previous range of -0.75% to +0.25% The SNB issues the world's largest paper bearer note denomination, the hefty CHF 1000 note (pictured above). It's worth around US$1143. The first is significant because as yet, no central bank has ever brought rates this deep into negative territory. The ECB's current deposit rate is set at -0.2% while Denmark's central bank, the Danmarks Nationalbank (DNB), applied a negative deposit rate of -0.2% on deposits that banks placed with the DNB in 2012. Neither of these top the SNB's ultra-low -0.75% rate. T...

Shibboleth , by Doris Scalcedo John Cochrane writes an interesting post that makes the case that removing or penalizing cash would not remove an economy's 0% lower bound. Briefly, the zero lower bound problem arises when a central bank tries to reduce the interest rate on central bank deposits below zero. Because cash always yields a superior 0% yield, everyone will race to convert their deposits into cash, thus preventing a negative interest rate from ever emerging. By removing cash, this escape route is plugged and a central bank can safely guide rates to -4 or -5%. Cochrane's point is that even if cash is removed, there are a number of alternative 0% yielding 'exits' to which people will flee, the effect being that rates will be inhibited from falling much below 0%. The examples he provides includes prepayment of taxes, bills, and mortgage payments, and the hoarding of gift cars or stored value cards like subway passes. In a follow-up post , he mentions a strategy o...

David Beckworth had a very interesting pair of posts outlining how QE would only have had a meaningful effect on the economy if the associated monetary base growth was permanent. One addendum I'd add on the topic is that even permanent expansions of the monetary base can have no effect on the economy. The best example of this is the "cashing up" of the Reserve Bank of New Zealand (RBNZ) in 2006, an event that doesn't get the attention that it deserves in monetary lore. Banks typically hold deposit balances at their central bank in order clear payments with other banks. Because New Zealand's clearing and settlement system was suffering signs of stress in the mid-2000s including delayed payments, hoarding of collateral, and increased use of the RBNZ standing lending facilities, the RBNZ decided to 'flood' the system with balances to make things more fluid. This involved conducting open market purchases that bloated the monetary base (comprised of currency...
